Script: Visible Overworld Wild Encounter

[derFischae]

Can you add new types of overworld spawns?

I assume that you use Pokemon Essentials V19.1 and Visible Overworld Wild Encounters Plugin Version V19.1.0.3.

If you want to include overworld versions for the default encounter types then you can simply include the plugin "Different Spawn And Normal Encounters - Overworld Encounters Add On" to your project. You can find it at https://github.com/VisibleOverworldWildEncounters/Visible-Overworld-Wild-Encounters

If you want to include your own new custom encounter types (for instance "desert") then you have to do the following:

1. At first, you have to add your custom encounter type as usual to your project. If you are not familiar with that then you find an explaination in the following spoiler section
   
   Spoiler:

   
   Adding a custom encounter type is described in more detail in https://www.reddit.com/r/PokemonRMXP/comments/nac0zx/new_encounter_types_with_new_scripts_in_v19/ and https://essentialsdocs.fandom.com/wiki/Adding_new_encounter_methods
   Basically it consists of the following steps
   

   1. Add a new environment (this is needed if the encounter happens on a new area, such as a desert). This might look something like this
      

      GameData::Environment.register({
        :id          => :Desert,
        :name        => _INTL("Desert"),
        :battle_base => "desert"
      })

   2. Add a new terrain tag. This might look similar to this
      

      GameData::TerrainTag.register({
        :id                     => :Desert,
        :id_number              => 17,
        :battle_environment     => :Desert # or an already existing environment such as :Grass if the encounter does not happen on a new area
      })

   3. Add new encounter types. This might be something like this
      

      GameData::EncounterType.register({
        :id             => :Desert,
        :type           => :desert, # or an already existing type such as :land or :cave if the encounter does not happen on a new area
        :trigger_chance => 21,
        :old_slots      => [20, 20, 10, 10, 10, 10, 5, 5, 4, 4, 1, 1]
      })

      plus additional encounter types per time such as DesertDay, DesertNight, ...
   4. Overwrite the method encounter_type of class PokemonEncounters in script section /Scripts/012_Overworld/002_Battle triggering/003_Overworld_WildEncounters.rb to make encountering work. Probably, encounter_type will look similar to this
      

        def encounter_type
          time = pbGetTimeNow
          ret = nil
          if $PokemonGlobal.surfing
            ret = find_valid_encounter_type_for_time(:Water, time)
          else   # Land/Cave (can have both in the same map)
            if has_land_encounters? && $game_map.terrain_tag($game_player.x, $game_player.y).land_wild_encounters
              ret = :BugContest if pbInBugContest? && has_encounter_type?(:BugContest)
              ret = find_valid_encounter_type_for_time(:Land, time) if !ret
            end
            # here the desert encounter is added ---
            if !ret && has_encounter_type?(:desert) && $game_map.terrain_tag($game_player.x, $game_player.y).battle_environment == :Desert
              ret = find_valid_encounter_type_for_time(:Desert, time)
            # --------------------------------------
            if !ret && has_cave_encounters?
              ret = find_valid_encounter_type_for_time(:Cave, time)
            end
          end
          return ret
        end

   5. If the encounter should happen on a new area (as it is in our example "desert"), then set the terrain tag (in our example 17) onto all that tiles where you want the encounter to happen. Use the the debug section while running your game to do that. Note that the probabilities defined for each Pokemon in the encounters must be the same as the ':old_slots' defined in the 'EncounterType' script. Otherwise your game will raise an error.
2. Overwrite the method encounter_type_on_tile of class PokemonEncounters in the Visible Overworld Wild Encounters Plugin to make overworld encountering work. Probably, encounter_type_on_tile needs to be something like this
   

     def encounter_type_on_tile(x,y)
       time = pbGetTimeNow
       ret = nil
       if $game_map.terrain_tag(x,y).can_surf_freely
         ret = find_valid_encounter_type_for_time(:Water, time)
       else   # Land/Cave (can have both in the same map)
         if has_land_encounters? && $game_map.terrain_tag(x, y).land_wild_encounters
           ret = :BugContest if pbInBugContest? && has_encounter_type?(:BugContest)
           ret = find_valid_encounter_type_for_time(:Land, time) if !ret
         end
         # here the desert encounter is added ---
         if !ret && has_encounter_type?(:desert) && $game_map.terrain_tag($game_player.x, $game_player.y).battle_environment == :Desert
           ret = find_valid_encounter_type_for_time(:Desert, time)
         # --------------------------------------
         if !ret && has_cave_encounters?
           ret = find_valid_encounter_type_for_time(:Cave, time)
         end
       end
       return ret
     end

If you want new custom encounter types (such as "desert") where you have different pokemon for spawning and for instant battle then

1. install the plugin "Different Spawn And Normal Encounters - Overworld Encounters Add On" from https://github.com/VisibleOverworldWildEncounters/Visible-Overworld-Wild-Encounters
2. add your custom encounter types to your project as it is written in the spoiler section above.
3. Add corresponding Overworld encounter types for all your custom encounter types. This might be something like this
   

   GameData::EncounterType.register({
     :id             => :OverworldDesert,
     :type           => :desert, # or an already existing type such as :land or :cave if the encounter does not happen on a new area
     :trigger_chance => 21,
     :old_slots      => [20, 20, 10, 10, 10, 10, 5, 5, 4, 4, 1, 1]
   })

   plus additional encounter types per time such as OverworldDesertDay, OverworldDesertNight, ...
4. Overwrite the method encounter_type_on_tile of class PokemonEncounters in the "Different Spawn And Normal Encounters - Overworld Encounters Add On" plugin (and not in the "Visible Overworld Wild Encounters" Plugin) to make different overworld encountering work. Probably, encounter_type_on_tile needs to be something like this
   

     def encounter_type_on_tile(x,y)
       time = pbGetTimeNow
       ret = nil
       if $game_map.terrain_tag(x,y).can_surf_freely
         ret = find_valid_encounter_type_for_time(:OverworldWater, time)
         ret = find_valid_encounter_type_for_time(:Water, time) if !ret && VisibleEncounterSettings::LET_NORMAL_ENCOUNTERS_SPAWN
       else   # Land/Cave (can have both in the same map)
         if has_land_encounters? && $game_map.terrain_tag(x, y).land_wild_encounters
           ret = :OverworldBugContest if pbInBugContest? && has_encounter_type?(:OverworldBugContest)
           ret = :BugContest if pbInBugContest? && has_encounter_type?(:BugContest) if !ret && VisibleEncounterSettings::LET_NORMAL_ENCOUNTERS_SPAWN
           ret = find_valid_encounter_type_for_time(:OverworldLand, time) if !ret
           ret = find_valid_encounter_type_for_time(:Land, time) if !ret && VisibleEncounterSettings::LET_NORMAL_ENCOUNTERS_SPAWN
         end
         # here the desert encounter is added ---
         if !ret && has_encounter_type?(:desert) && $game_map.terrain_tag($game_player.x, $game_player.y).battle_environment == :Desert
           ret = find_valid_encounter_type_for_time(:OverworldDesert, time)
           ret = find_valid_encounter_type_for_time(:Desert, time) if !ret && VisibleEncounterSettings::LET_NORMAL_ENCOUNTERS_SPAWN
         # --------------------------------------
         if !ret && has_cave_encounters?
           ret = find_valid_encounter_type_for_time(:OverworldCave, time)
           ret = find_valid_encounter_type_for_time(:Cave, time) if !ret && VisibleEncounterSettings::LET_NORMAL_ENCOUNTERS_SPAWN
         end
       end
       return ret
     end

 

[OverusedNameHere]

is there a way to possibly make it so that pokemon evolve when spawned in if they're a high enough level? i'm running this on 19.1 and havent found an operational way to implement this so far-

 

[Lynker]

This script works perfectly!! Thank you so much, this is EXACTLY what I wanted for my game. 😌

 

[derFischae]

is there a way to possibly make it so that pokemon evolve when spawned in if they're a high enough level? i'm running this on 19.1 and havent found an operational way to implement this so far-

Try this [EDIT: Updated code for PEv20]

EventHandlers.add(:on_wild_pokemon_created_for_spawning, :evolve_high_leveled_spawning_pokemon, proc { |pkmn| 
  next if !pkmn || pkmn.egg?
  new_species = pkmn.check_evolution_on_level_up
  next if new_species.nil?
  # Evolve Pokémon if possible
  pkmn.species = new_species
  pkmn.calc_stats
  pkmn.ready_to_evolve = false
  # See and own evolved species
  moves_to_learn = []
  movelist = pkmn.getMoveList
  movelist.each do |i|
    next if i[0] != 0 && i[0] != pkmn.level   # 0 is "learn upon evolution"
    moves_to_learn.push(i[1])
  end
  # Learn moves upon evolution for evolved species
  moves_to_learn.each do |move|
    # Pokémon already knows the move
    next if pkmn.hasMove?(move)
    # Pokémon has space for the new move; just learn it
    if pkmn.numMoves < Pokemon::MAX_MOVES
      pkmn.learn_move(move)
      next
    end
    # Pokémon already knows the maximum number of moves; try to forget one to learn the new move
    forgetMove =  rand(Pokemon::MAX_MOVES) 
    pkmn.moves[forgetMove] = Pokemon::Move.new(move)   # Replaces current/total PP
  end
})

Simply copy and paste this code at the bottom of the visible overworld wild encounter script.

This code checks if the level of a spawning pokemon is high enough to start evolution and triggers it, without showing an evolution scene. So, the evolved pokemon will spawn. If you want to change this code more for your liking then I recommand to read the spoiler section about "instructions on how to make your own Add-On or to modify an already existing script to make it work with the visible overworld wild encounter script. This includes modifying a pokemon on spawning but not on battling again, by using the events OnStartBattle, OnWildPokemonCreate and OnWildPokemonCreateForSpawning" in the main post https://www.pokecommunity.com/showthread.php?p=10472596#post10472596

If you want that pokemon can evolve not only into there next evolution form but also in even higher forms, then use a loop around the block of code, i. e.

EventHandlers.add(:on_wild_pokemon_created_for_spawning, :evolve_high_leveled_spawning_pokemon, proc { |pkmn| 
  loop do
    next if !pkmn || pkmn.egg?
    new_species = pkmn.check_evolution_on_level_up
    break if new_species.nil?
    # Evolve Pokémon if possible
    pkmn.species = new_species
    pkmn.calc_stats
    pkmn.ready_to_evolve = false
    # See and own evolved species
    moves_to_learn = []
    movelist = pkmn.getMoveList
    movelist.each do |i|
      next if i[0] != 0 && i[0] != pkmn.level   # 0 is "learn upon evolution"
      moves_to_learn.push(i[1])
    end
    # Learn moves upon evolution for evolved species
    moves_to_learn.each do |move|
      # Pokémon already knows the move
      next if pkmn.hasMove?(move)
      # Pokémon has space for the new move; just learn it
      if pkmn.numMoves < Pokemon::MAX_MOVES
        pkmn.learn_move(move)
        next
      end
      # Pokémon already knows the maximum number of moves; try to forget one to learn the new move
      forgetMove =  rand(Pokemon::MAX_MOVES) 
      pkmn.moves[forgetMove] = Pokemon::Move.new(move)   # Replaces current/total PP
    end
  end
})

Does anyone else's spawning take a long time? It seems to take at least 20-30 seconds upon walking onto the route.

Also, it seems to make the map connections screen lag very bad. Not completely sure why.

Edit- One more thing! How can I make certain Pokemon appear only on water or sand?

There are multiple settings in the overworld encounters script and add-ons that let you change the spawning rate. Moreover you can change the encounter chance for your maps as usual, see the Pokemon Essentials Manual for more details. And the spawning rate depends on how much grass is on your road. Clearly, less grass means less tiles a pokemon can spawn at.

What do you mean by "map connection screen"? And how did you open it, so I may reproduce your issue myself. Have you tried to remove this script and test it again and does the lag still remain? The lag my come from a different script.

You add water pokemon as usual, see the Pokemon Essentials Manual for more details.

If you want pokemon to spawn on specific tiles such as sand, then read the spoiler section

• How to add your own new custom overworld encounter types (such as "desert")

in the Modifications section of the main post https://www.pokecommunity.com/showpost.php?p=10472596&postcount=414

 

[Lynker]

I'm happy with the spawning rate for the maps, it's just that the initial spawn takes awhile.

I go through the debug menu to get the the map connections. I will try removing the script and see if it "fixes" it.

Also, thank you!!

 

[derFischae]

I'm happy with the spawning rate for the maps, it's just that the initial spawn takes awhile.

As we all know, it is annoying to run into the next wild battle just a few steps after your last one.
That's why Pokemon Essentials implements an encounter chance that is low after a wild battle and increases each step. So, it might suppress 8 pokemons to spawn, before a new pokemon encounters.
This is totally fine for normal encounters. Unfortunately, this might result in your mentioned odd behaviour for spawning encounters, since the encounter chance will be reset after a battle and not after a pokemon has spawned.
So, it will take long for the first pokemon to spawn, and then it will be fast and gets even faster the more steps the game player makes, until the game player runs into a pokemon and triggers a battle.

How to stop this? There are multiple ways.

• The easiest way is to reset the encounter chance back to zero every time a pokemon spawned.
  This can be archieved with the following code snipped (simply copy and paste it at the bottom of your visible overworld wild encounter script)
  

  EventHandlers.add(:on_wild_pokemon_created_for_spawning, :reset_step_count,
    proc { |pkmn|
      $PokemonEncounters.reset_step_count
    }
  )

  With this solution, the spawning rate will be always similar to the spawning rate of the first pokemon. If this is to long for you, then you can increase the encounter rate in the classical encounter settings for your maps and encounter types as usual.
  
• You can use TrankerGold's Add-On "Fixed Spawn Probability" for the Overworld Encounter Plugin. It gets rid of the variable encounter probability and sets a fixed one, which you can set yourself in the variable VISIBLE_ENCOUNTER_PROBABILITY the settings section in the code of that Add-On
  With this Add-On the spawning probability will be the same on every map and on every encounter type, whether it is grass, cave of water.
  
• You can make our own encounter chance explicitly for spawning encounters, that increases by step (but maybe faster as the original encounter chance) and resets to zero when a pokemon spawns. This can be archieved by the "Own Minimum Spawn Chance - Overworld Encounters Add On", which can be found on github.
  With this code all pokemon, whether the first one or the later ones will have the same average spawning time.
  Moreover, you can set the variable MAX_ENCOUNTER_REDUCED = 0 in the plugin, then all pokemon will have the usual spawn probability as you set it for the maps and encounter types (default grass 21%, Cave 5%, water 2%) in your Pokemon Essentials project. I.e. the spawn probability is as high as it was previously for all pokemon except the first one.
  Setting this variable MAX_ENCOUNTER_REDUCED larger than zero will increase the average spawning time of all pokemon simultanously.

I would prefer the last way, where I set MAX_ENCOUNTER_REDUCED = 0 or MAX_ENCOUNTER_REDUCED = 1 or MAX_ENCOUNTER_REDUCED = 2 (and increase the default spawning chances in Pokemon Essentials, since 2% is pretty low for water encounters).
EDIT: Updated code for PEv20.

I go through the debug menu to get the the map connections. I will try removing the script and see if it "fixes" it.
Also, thank you!!

I also have checked the map connection screen. And indeed, the screen always needs quite a long time to start, whether with or without the visible overworld wild encounter screen. So, I would say that this lag does not come from the visible overworld wild encounters script. I would have been surprised too, if the lag would come from the script.

 

[Lynker]

Thank you so much!

* Visible Overworld Wild Encounters Version 20.0.0.4 for PEv20 and PEv21 - by derFischae (Credits if used please) *

UPDATED TO VERSION 20.0.0.4 FOR POKEMON ESSENTIALS V20 and V21.

This script is for Pokémon Essentials v20, v20.1, v21 and v21.1 (for short PEv20 and PEv21).

As in Pokemon Let's go Pikachu/Eevee or Pokemon Shield and Sword wild encounters pop up on the overworld, they move around and you can start the battle with them simply by moving to the pokemon. Clearly, you also can omit the battle by circling around them.

FEATURES

• Easy Install as Plugin
• see the pokemon on the overworld before going into battle
• no forced battling against overworld encounters
• Supports individual sprites for shiny, female and alternative forms
• plays the pokemon cry while spawning
• Overworld pokemon will despawn after some steps
• you can have instant wild battle and overworld spawning at the same time and set the propability of that in percentage
• In caves, pokemon don't spawn on impassable Rock-Tiles, which have the Tile-ID 4
• In water, pokemon won't spawn above other tiles, which made them stuck or walk on ground
• See "advanced features" and "additional features by add-ons" below for more (e.g. additional animations...)

INSTALLATION
Installation as simple as it can be.

1. Add Graphics: Either get the resources from Gen 8 Project (broken link removed)
   and install the "Graphics/Characters" folder in your game file system.
   Or you watch in the following spoiler section
   
   Spoiler:

   
   Place your own sprites for your pokemon/fakemon with the right names in your "\Graphics\Characters\Follower" folder and your shiny sprites in your "\Graphics\Characters\Follower shiny" folder.
   The right name of sprites is:
   usual form - SPECIES.png where SPECIES is the species name in capslock (e.g. PIDGEY.png)
   alternate form - SPECIES_n.png where n is the number of the form (e.g. PIKACHU_3.png)
   female form - SPECIES_female.png or SPECIES_n_female (e.g. PIDGEY_female.png or PIKACHU_3_female.png)
   
2. Add Script: Follow this link https://github.com/VisibleOverworldWildEncounters/V20 and copy the folder "Visible Overworld Wild Encounters - Script" to your "/plugins/" folder.
3. [Optional] Change Settings: Open the script file in the folder and change the parameters in the settings section therein as you like. Details descriptions about the parameters can be found there as well.
4. [optional] Install Add-Ons (the folders under "/optional/" in the github repository): There are a lot of Add-Ons and parameter settings for your personal optimal solution. So, Copy Add-Ons in your "/plugins/" folder and edit parameters in settings of that Add-Ons to your liking. Some Add-Ons are incompatible to each other and some Add-On and parameter combinations can produce lag, e.g. a high spawning rate without a spawning cap, or e.g. "NO_OF_CHOSEN_TILES=0" (or too high) when having other scripts like Pokemon Following. So, do not simply include all folders.
5. Enjoy!

    Spoiler:

    
    

    In this post I bring not Add-On, but an animation resource.
    
    So, for everyone who haven't noticed yet the new script for PEv19.1 has parameters to store the id of specific animations.
    Currently, since the only thing provided is code there was no need for this kind of thing.
    But for anyone that is interested in this, here are some examples on what you can do with them:
    

    Spoiler:

    
    

    

    

    

    
    (When shiny or agressive the animations have a specific sound effect so you can notice without looking)
    

    
    You can find these new animations I created in this download.
    
    (WARNING! This resource overrides your current animations.rxdata which contains all animations from the database, DON'T use this resource if you already edited yours.)
    
    If you already have your own animations and still want to try these ones here is a little tip:
    

    Spoiler:

    - First, copy your project folder (or download PEv19.1)
    - Second, paste there (in the copy) the animations.rxdata in Data folder
    - Third, open both your project and the copied project with the animations
    - Fourth, in the copied project open database, go to Animations, click "008: Shiny", and do Ctrl+C
    - Fifth, in your own proyect do the same but click a blank space with no animations and do Ctrl+V
    - Sixth, do the 4th and 5th step with:
        - "009: Shiny no sound"
        - "010: Water splash"
        - "011: Agressive"
    - Seventh, make sure your project has the audio and graphic
    - Eighth, change in VisibleEncounterSettings the id for the animations

    You can totally make your own animations instead, and remember this is for the script that works with PEv19.1 version.

• How to add your own new custom overworld encounter types (such as "desert")
  
  Spoiler:

  
  These instructions are for Visible Overworld Wild Encounters Plugin Version 20.0.0.1 for PEv20. Nevertheless the last time it was tested was with PEv19.1, but it should work.
  
  If you want to include overworld versions for the default encounter types then you can simply include the plugin "Different Spawn And Normal Encounters - Overworld Encounters Add On" to your project. You can find it at https://github.com/VisibleOverworldWildEncounters/V20
  
  If you want to include your own new custom encounter types (for instance "desert") then you have to do the following:
  

  1. At first, you have to add your custom encounter type as usual to your project. If you are not familiar with that then you find an explaination in the following spoiler section
     
     Spoiler:

     
     Adding a custom encounter type is described in more detail in

     https://www.reddit.com/r/PokemonRMXP/comments/nac0zx

     and https://essentialsdocs.fandom.com/wiki/Adding_new_encounter_methods
     Basically it consists of the following steps
     

     1. Add a new environment (this is needed if the encounter happens on a new area, such as a desert). This might look something like this
        

        GameData::Environment.register({
          :id          => :Desert,
          :name        => _INTL("Desert"),
          :battle_base => "desert"
        })

     2. Add a new terrain tag. This might look similar to this
        

        GameData::TerrainTag.register({
          :id                     => :Desert,
          :id_number              => 17,
          :battle_environment     => :Desert # or an already existing environment such as :Grass if the encounter does not happen on a new area
        })

     3. Add new encounter types. This might be something like this
        

        GameData::EncounterType.register({
          :id             => :Desert,
          :type           => :desert, # or an already existing type such as :land or :cave if the encounter does not happen on a new area
          :trigger_chance => 21,
          :old_slots      => [20, 20, 10, 10, 10, 10, 5, 5, 4, 4, 1, 1]
        })

        plus additional encounter types per time such as DesertDay, DesertNight, ...
     4. Overwrite the method encounter_type of class PokemonEncounters in script section /Scripts/012_Overworld/002_Battle triggering/003_Overworld_WildEncounters.rb to make encountering work. Probably, encounter_type will look similar to this
        

          def encounter_type
            time = pbGetTimeNow
            ret = nil
            if $PokemonGlobal.surfing
              ret = find_valid_encounter_type_for_time(:Water, time)
            else   # Land/Cave (can have both in the same map)
              if has_land_encounters? && $game_map.terrain_tag($game_player.x, $game_player.y).land_wild_encounters
                ret = :BugContest if pbInBugContest? && has_encounter_type?(:BugContest)
                ret = find_valid_encounter_type_for_time(:Land, time) if !ret
              end
              # here the desert encounter is added ---
              if !ret && has_encounter_type?(:desert) && $game_map.terrain_tag($game_player.x, $game_player.y).battle_environment == :Desert
                ret = find_valid_encounter_type_for_time(:Desert, time)
              # --------------------------------------
              if !ret && has_cave_encounters?
                ret = find_valid_encounter_type_for_time(:Cave, time)
              end
            end
            return ret
          end

     5. If the encounter should happen on a new area (as it is in our example "desert"), then set the terrain tag (in our example 17) onto all that tiles where you want the encounter to happen. Use the the debug section while running your game to do that. Note that the probabilities defined for each Pokemon in the encounters must be the same as the ':old_slots' defined in the 'EncounterType' script. Otherwise your game will raise an error.
  2. Overwrite the method encounter_type_on_tile of class PokemonEncounters in the Visible Overworld Wild Encounters Plugin to make overworld encountering work. Probably, encounter_type_on_tile needs to be something like this
     

       def encounter_type_on_tile(x,y)
         time = pbGetTimeNow
         ret = nil
         if $game_map.terrain_tag(x,y).can_surf_freely
           ret = find_valid_encounter_type_for_time(:Water, time)
         else   # Land/Cave (can have both in the same map)
           if has_land_encounters? && $game_map.terrain_tag(x, y).land_wild_encounters
             ret = :BugContest if pbInBugContest? && has_encounter_type?(:BugContest)
             ret = find_valid_encounter_type_for_time(:Land, time) if !ret
           end
           # here the desert encounter is added ---
           if !ret && has_encounter_type?(:desert) && $game_map.terrain_tag($game_player.x, $game_player.y).battle_environment == :Desert
             ret = find_valid_encounter_type_for_time(:Desert, time)
           # --------------------------------------
           if !ret && has_cave_encounters?
             ret = find_valid_encounter_type_for_time(:Cave, time)
           end
         end
         return ret
       end

  
  If you want new custom encounter types (such as "desert") where you have different pokemon for spawning and for instant battle then
  

  1. install the plugin "Different Spawn And Normal Encounters - Overworld Encounters Add On" from https://github.com/VisibleOverworldWildEncounters/Visible-Overworld-Wild-Encounters
  2. add your custom encounter types to your project as it is written in the spoiler section above.
  3. Add corresponding Overworld encounter types for all your custom encounter types. This might be something like this
     

     GameData::EncounterType.register({
       :id             => :OverworldDesert,
       :type           => :desert, # or an already existing type such as :land or :cave if the encounter does not happen on a new area
       :trigger_chance => 21,
       :old_slots      => [20, 20, 10, 10, 10, 10, 5, 5, 4, 4, 1, 1]
     })

     plus additional encounter types per time such as OverworldDesertDay, OverworldDesertNight, ...
  4. Overwrite the method encounter_type_on_tile of class PokemonEncounters in the "Different Spawn And Normal Encounters - Overworld Encounters Add On" plugin (and not in the "Visible Overworld Wild Encounters" Plugin) to make different overworld encountering work. Probably, encounter_type_on_tile needs to be something like this
     

       def encounter_type_on_tile(x,y)
         time = pbGetTimeNow
         ret = nil
         if $game_map.terrain_tag(x,y).can_surf_freely
           ret = find_valid_encounter_type_for_time(:OverworldWater, time)
           ret = find_valid_encounter_type_for_time(:Water, time) if !ret && VisibleEncounterSettings::LET_NORMAL_ENCOUNTERS_SPAWN
         else   # Land/Cave (can have both in the same map)
           if has_land_encounters? && $game_map.terrain_tag(x, y).land_wild_encounters
             ret = :OverworldBugContest if pbInBugContest? && has_encounter_type?(:OverworldBugContest)
             ret = :BugContest if pbInBugContest? && has_encounter_type?(:BugContest) if !ret && VisibleEncounterSettings::LET_NORMAL_ENCOUNTERS_SPAWN
             ret = find_valid_encounter_type_for_time(:OverworldLand, time) if !ret
             ret = find_valid_encounter_type_for_time(:Land, time) if !ret && VisibleEncounterSettings::LET_NORMAL_ENCOUNTERS_SPAWN
           end
           # here the desert encounter is added ---
           if !ret && has_encounter_type?(:desert) && $game_map.terrain_tag($game_player.x, $game_player.y).battle_environment == :Desert
             ret = find_valid_encounter_type_for_time(:OverworldDesert, time)
             ret = find_valid_encounter_type_for_time(:Desert, time) if !ret && VisibleEncounterSettings::LET_NORMAL_ENCOUNTERS_SPAWN
           # --------------------------------------
           if !ret && has_cave_encounters?
             ret = find_valid_encounter_type_for_time(:OverworldCave, time)
             ret = find_valid_encounter_type_for_time(:Cave, time) if !ret && VisibleEncounterSettings::LET_NORMAL_ENCOUNTERS_SPAWN
           end
         end
         return ret
       end

• instructions on how to make your own Add-On or to modify an already existing script to make it work with the visible overworld wild encounter script. This includes modifying a pokemon on spawning but not on battling again, by using the events :on_wild_species_chosen, :on_wild_pokemon_created, :on_calling_wild_battle and :on_wild_pokemon_created_for_spawning
  
  Spoiler:

  
  This instruction is for you
  

  • if you plan to modify your overworld encounters right on creation or right on battle start, such as making your overworld encounters shiny or evolving the encounters if they spawn with a suitable high level, or
  • if you want to add a script to your project that modifies encounters right on the creating the pokemon or right on battle start but is written only for the ordinary case of instant battle with wild pokemon, such as Vendilys Rescue Chain or Joltiks Level Balance.

  Lots of other scripts out there work as suggested with this script. But some scripts might need to be modified to make them work properly with the visible overworld encounter script. Here I give you some instructions for that.
  
  TYPES OF ENCOUNTERS
  In your pokemon game, you can have 3 types of encounters.
  

  • normal encounters,
  • overworld encounters and
  • events which you have placed by your own in the map editor that force a wild battle, which also counts somehow as normal encounters.

  To have overworld encounters and normal encounters at the same time, you can set the parameter INSTANT_WILD_BATTLE_PROPABILITY = 1,2,3,4,... or 99 in the settings section of the visible overworld wild encounter script before starting the game, or you use additional plugins such as "Variable Spawn To Normal Encounter Proportion During Game - Overworld Encounters Add On".
  
  So, you might come to the point that you want to modify a pokemon or run a certain procedure in battle only for overworld encounters, only for normal encounters or for all encounters.
  
  USING EVENTS
  Concerning Wild Pokemon, there are multiple Events, which trigger before a wild overworld pokebattle, and can be used to modify the encounter.
  

  • :on_calling_wild_battle
    At first, the event :on_calling_wild_battle triggers right before the battle. This includes running into a spawned overworld pokemon and instant battles with normal encounters and running into your map events that trigger as wild battles.
    You can add a procedure to this event, so that procedure will run when going into battle.
    See the Pokemon Essentials manual if you want to read more on how to use it.
  • :on_battle_start
    The event :on_battle_start triggers right before the battle. This includes running into a spawned overworld pokemon and instant battles with normal encounters and running into your map events that trigger as wild battles.
    You can add a procedure to this event, so that procedure will run when going into battle.
    See the Pokemon Essentials manual if you want to read more on how to use it.
    NOTE that Pokemon Essentials v20 does not support to modify the encountering pokemon in OnStartBattle, nevertheless OnStartBattle can be used for lots of other stuff.
  • :on_wild_species_chosen
    Another event is :on_wild_species_chosen. This event triggers every time a wild pokemon needs to be created. This includes creating a pokemon right before it spawns on the overworld and creating wild pokemon right before a normal instant battle starts.
    Typically it is used to change the species and level, e.g. to replace an encounter by an roaming pokemon.
    You can add a procedure to this event, so that procedure will run in that described situations. And you can use this event to modify the encountering pokemon.
    You find more instructions in the Pokemon Essentials manual.
  • :on_wild_pokemon_created
    Another event is :on_wild_pokemon_created. This event triggers after :on_wild_species_chosen every time a wild pokemon needs to be created. This includes creating a pokemon right before it spawns on the overworld and creating wild pokemon right before a normal instant battle starts. But this also includes event that you have placed on the map in the map editor and that will start a pokemon battle when triggered.
    You can add a procedure to this event, so that procedure will run in that described situations. And you can use this event to modify the encountering pokemon.
    You find more instructions in the Pokemon Essentials manual.
    So, you can still use all your old scripts which make use of the event :on_wild_species_chosen, :on_wild_pokemon_created and of :on_calling_wild_battle (as long as they are not from an outdated Pokemon Essentials version).
  • :on_wild_pokemon_created_for_spawning
    The visible wild overworld encounter script introduces a new event :on_wild_pokemon_created_for_spawning.
    It can be used the same way as the event :on_wild_pokemon_created, but this event will only trigger when a pokemon wants to spawn on the overworld, and it does not trigger in any other situations.
    If you want to add a procedure that modifies a pokemon only for spawning but not before battling then you can do it with this event.
    Simply add that procedure to the event :on_wild_pokemon_created_for_spawning. The code you need to write for that will look exactly the same as for the event :on_wild_pokemon_created. So read the Pokemon Essentials manual about :on_wild_pokemon_created for more informations.

  
  Using these events will give you a good way to include your modification. Unfortunately, it will not distinguish good enough between spawning encounters and normal encounters. But the next section will tell you how to do so.
  
  MODIFYING SPECIFIC ENCOUNTERS
  To distinguish between normal encounters and spawned encounters, the visible overworld wild encounter script introduces two new global variables.
  

  • $PokemonGlobal.battlingSpawnedPokemon
    During events, such as :on_wild_pokemon_created, you can use $PokemonGlobal.battlingSpawnedPokemon to decide if you are going into battle against an overworld encounter (true) or not (nil or false), including battling a normal encounter or not battling at all.
  • $PokemonGlobal.creatingSpawningPokemon
    During events, you can use $Pokemon.creatingSpawningPokemon in :on_wild_pokemon_created and :on_wild_pokemon_created_for_spawning to decide if a pokemon is created to let it spawn on the map (true) or for any other reason (nil or false).

  
  Combining both global variables makes it possible to distinguish every situation when a pokemon is created.
  
  For example, if you want to add a procedure that triggers only when going into battle with spawned pokemon then use this code snipped
  

  EventHandlers.add(:on_calling_wild_battle, :your_battle_proc,
    proc { |species, level, handled|
     if $PokemonGlobal.battlingSpawnedPokemon
       #The actual code of your procedure you want to run only when battling overworld encounters.
     end
    }
  )

  Of course, !$PokemonGlobal.battlingSpawnedPokemon in the code snipped above would mean that the procedure will run only for normal encounters and wild pokebattle events on the map.
  
  If you want to add a procedure to the event @@OnWildPokemonCreate and you want that this procedure runs only on creation of an overworld encounter use this code snippet (or simply use @@OnWildPokemonCreateForSpawning)
  

  EventHandlers.add(:on_wild_pokemon_created, :your_proc_name,
    proc { |pkmn|
     if $PokemonGlobal.creatingSpawningPokemon
       #The actual code of your procedure you want to run only when a pokemon is created for spawning.
     end
    }
  )

  Of course, !$PokemonGlobal.creatingSpawningPokemon in the code snipped above would mean that the procedure will run only for normal encounters and wild pokebattle events on the map.
  
  Concerning the event :on_wild_pokemon_created, you can find the other if conditions and its meaning below
  
  

  $PokemonGlobal.battlingSpawnedPokemon # means procedure never triggers, since onWildPokemonCreate will not trigger for spwned encounters
  !$PokemonGlobal.battlingSpawnedPokemon # means procedure triggers always, i.e. for instant battles, during spawning and for handplaced map events
  $PokemonGlobal.creatingSpawningPokemon # means procedure triggers when a pokemon is created for spawning
  !$PokemonGlobal.creatingSpawningPokemon # means procedure triggers in every situation except that it is created for spawning, including instant battles and triggering handplaced pokeevents on the map
  $PokemonGlobal.battlingSpawnedPokemon and $PokemonGlobal.creatingSpawningPokemon # equals $PokemonGlobal.battlingSpawnedPokemon
  $PokemonGlobal.battlingSpawnedPokemon and !$PokemonGlobal.creatingSpawningPokemon # equals $PokemonGlobal.battlingSpawnedPokemon
  !$PokemonGlobal.battlingSpawnedPokemon and $PokemonGlobal.creatingSpawningPokemon # equals $PokemonGlobal.creatingSpawningPokemon
  !$PokemonGlobal.battlingSpawnedPokemon and !$PokemonGlobal.creatingSpawningPokemon # equals $PokemonGlobal.creatingSpawningPokemon

  If you want pokemon to spawn on specific tiles such as sand, then read the spoiler section "How to add your own new custom overworld encounter types (such as "desert")" in the Modifications section

About Good Spawning Rate

• What's a good spawn rate for this code? I don't want too many Pokemon on the field, but I don't want it to take forever to spawn an individual Pokemon.

  Spoiler: Answer

  
  

  There are multiple settings in the overworld encounters script and add-ons that let you change the spawning rate. Moreover you can change the encounter chance for your maps as usual, see the Pokemon Essentials Manual for more details. And the spawning rate depends on how much grass is on your road. Clearly, less grass means less tiles a pokemon can spawn at.

• Does anyone else's spawning take a long time? It seems to take at least 20-30 seconds upon walking onto the route.
  I'm happy with the spawning rate for the maps, it's just that the initial spawn takes awhile.

About Move Independent Spawning

• is there a way to modify the script so that instead of working when the player makes a step, making this working based on time? For example calling the "step function" every second in time. It would look more realistic in my opinion, so that you can stand in the same spot and the Pokémon keep on spawning and despawning.

• Do you think there is any way to make it work only if a switch is activated? Perhaps in this way we can make special maps or items that allow you to see the Pokemon in the grass for a certain amount of time ...

  Spoiler: Answer

  Let's say, you want to let the script work only if the game switch 12345678 is on.
  Then add the following code snippet
  

  alias map_pbBattleOrSpawnOnStepTaken pbBattleOrSpawnOnStepTaken
  def pbBattleOrSpawnOnStepTaken(repel_active)
    return false if $game_switches[12345678]==false
    return map_pbBattleOrSpawnOnStepTaken(repel_active)
  end

  to the bottom of your visible overworld wild encounters script. Make sure that no other modifications or add-ons of the visible overworld wild encounters script, which you use, overwrite the method "pbBattleOrSpawnOnStepTaken".

About Overworld Pokemon And Cutscenes

• I just ran into an issue as an aggressive encounter spawned just before I started an event cutscene. The player has forced movement in it and the encounter blocked the path. I have prevented this with "ignore if can't move", but the cutscene looks ugly with the encounter interfering. Is it possible to pause the overworld encounters until an event is over?

• I've been trying to implement solutions for the cutscenes, but I've only managed to stop the spawn encounters until the scene is over, but the Pokemon that already appeared before are still hanging around. I read the post and the suggestion of game_temp.in_menu = true but I would like to know (if I missed it somewhere), is there any command to just make all the Pokemon that have appeared on the map at that moment disappear?

[OverusedNameHere]

Try this

EventHandlers.add(:on_wild_pokemon_created_for_spawning, :evolve_high_leveled_spawning_pokemon,
  proc { |pkmn|
    newSpecies = pkmn.check_evolution_on_level_up
    next if !newSpecies
    # Modify Pokémon to make it evolved
    pkmn.species = newSpecies
    pkmn.form    = 0 if pkmn.isSpecies?(:MOTHIM)
    pkmn.calc_stats
    # Learn moves upon evolution for evolved species
    movelist = pkmn.getMoveList
    for i in movelist
      next if i[0]!=0 && i[0]!=pkmn.level   # 0 is "learn upon evolution"
      newMove = i[1]
      # Pokémon already knows the move
      return if pkmn.moves.any? { |m| m && m.id == newMove }
      # Pokémon has space for the new move; just learn it
      if pkmn.moves.length < Pokemon::MAX_MOVES
        pkmn.moves.push(Pokemon::Move.new(newMove))
        next
      end
      # Pokémon already knows the maximum number of moves; try to forget one to learn the new move
      forgetMove =  rand(Pokemon::MAX_MOVES) 
      pkmn.moves[forgetMove] = Pokemon::Move.new(newMove)   # Replaces current/total PP
    end
  }
)

Simply copy and paste this code at the bottom of the visible overworld wild encounter script.

This code checks if the level of a spawning pokemon is high enough to start evolution and triggers it, without showing an evolution scene. So, the evolved pokemon will spawn. If you want to change this code more for your liking then I recommand to read the spoiler section about "instructions on how to make your own Add-On or to modify an already existing script to make it work with the visible overworld wild encounter script. This includes modifying a pokemon on spawning but not on battling again, by using the events OnStartBattle, OnWildPokemonCreate and OnWildPokemonCreateForSpawning" in the main post https://www.pokecommunity.com/showthread.php?p=10472596#post10472596

TYSM AAAAAA

I tested it, works amazing. The only issue is that Pokémon like Lillipup will only evolve once in the case that it's high enough leveled to be a Stoutland; it'll just be a Herdier.

As you already noticed, the error comes from line 1259.
To fix this replace the line

    return if pkmn.moves.any? { |m| m && m.id == newMove }

by

    next if pkmn.moves.any? { |m| m && m.id == newMove }

This should solve the crashes. But your solution is very good as well.

Concerning higher evolutions, such as for Lillipup, Herdier and Stoutland:
To have multiple evolutions, you can simply place a loop around your block. Should look like this

Events.onWildPokemonCreate+=proc {|sender,e|
    pkmn = e[0]
    loop do
      newSpecies = pkmn.check_evolution_on_level_up
      break if !newSpecies
      # Modify Pokémon to make it evolved
      pkmn.species = newSpecies
      pkmn.form    = 0 if pkmn.isSpecies?(:MOTHIM)
      pkmn.calc_stats
      pkmn.reset_moves
      newSpecies = pkmn.check_evolution_on_level_up
      next if !newSpecies
      # Modify Pokémon to make it evolved (in case the Pokemon has another evolution)
      pkmn.species = newSpecies
      pkmn.calc_stats
      pkmn.reset_moves
    end
}

or you place a loop similarily around the other code (where the evolved pokemon can get there evolution-moves).

This error comes from the script "Advanced Pokemon Level Balancing". This script was written for Pokemon Essentials Version 17 by Joltik and it was updated for Pokemon Essentials version 18 by Phye. The corresponding thread is

https://www.pokecommunity.com/showthread.php?t=409828

Unfortunately, Joltiks' "Advanced Pokemon Level Balancing" script seems not to be updated for Pokemon Essentials version 19, which you use. Thus your error message comes from that incompatibility.

So, the easiest way to remove the error is to remove the "Advanced Pokemon Level Balancing" script from your fan game. If you still want to use that script, then you have to update the script for Pokemon Essentials version 19 by your own. Maybe you can ask for help in the thread https://www.pokecommunity.com/showthread.php?t=409828

Nevertheless, I want you to give you some instructions for updating.
Your error message says that the word "PBExperience" in line 64 of your "Advanced Pokemon Level Balancing" script causes the problem. I highlighted this in your error message above. Every error message works like that (compare the previous error message concerning "def_arg").

So the first step would be to find the new notation for that "PBExperience::MAXLEVEL". I would guess that it is "GameData::GrowthRate.max_level" now, but I'm not completely sure. And replace all code snippits by the new notation.

There will be even more that needs to be changed. For example all appearences of "MAXIMUMLEVEL" need to be replaced by "Settings::MAXIMUM_LEVEL". There to replace code will always be told by the error messages. Unfortunately, what to use to replace it can only be found by comparing Pokemon Essentials version 18 and 19.
