Script: Visible Overworld Wild Encounter

[derFischae]

This is the error showing up for me. It happens when I lose a wild battle and get sent to the Poke Center.
I don't appear to be missing anything, and I can't seem to find a fix to it on my own. Thoughts?
This is with the latest update to the script, I didn't change anything that I shouldn't have.

Exception: NoMethodError

Message: (eval):13:in `pbExecuteScript'undefined method `removeThisEventfromMap' for nil:NilClass

Thank you for reporting your issue. There was a bug in the script. I removed the bug and I will update this script to a new version v1.9 for all the other users.
Here is the working script:

Spoiler:

#===============================================================================
# * Visible Overworld Encounters V1.9 - by derFischae (Credits if used please) *
#===============================================================================
#
# UPDATED TO VERSION 1.9
#
# This script is for Pokémon Essentials 17.
# As in Pokemon Let's go Pikachu/Eevee or Pokemon Shild and Sword
# random 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 INCLUDED:
#   - see the pokemon on the overworld before going into battle
#   - no forced battling against random encounters
#   - plays the pokemon cry while spawning
#   - Choose whether encounters occure on all terrains or only on 
#     the terrain of the player
#   - if you kill the same species in a row, then you increase
#     the chance of spawning a shiny of that species or an evolved pokemon of that species family
#
# NEW FEATURES IN VERSION 1.1:
#   - less lag
#   - supports sprites for alternative forms of pokemon
#
# NEW FEATURES IN VERSION 1.2:
#   - supports sprites for female/male/genderless pokemon
#
# NEW FEATURES IN VERSION 1.3:
#   - bug fixes for roaming encounter and double battles
#
# NEW FEATURES IN VERSION 1.4:
#   - more options in settings
#
# NEW FEATURES IN VERSION 1.5:
#   - roaming encounters working correctly
#
# NEW FEATURES IN VERSION 1.6:
#   - more lag reduction 
#
# NEW FEATURES IN VERSION 1.7:
#   - included automatic spawning of pokemon, i.e. without spawning without having to move the player
#
# NEW FEATURES IN VERSION 1.8:
#   - included vendilys rescue chain, i. e. if pokemon of the same species family spawn in a row and will be battled in a row, then you increase the chance of spawning
#     an evolved pokemon of that species family. Link: https://www.pokecommunity.com/showthread.php?t=415524
#
# NEW FEATURES IN VERSION 1.9:
#   - removed bug occuring after fainting against wild overworld encounter
#   - for script-developers, shortened the spawnEvent method for better readablitiy
#
# INSTALLATION:
# Installation as simple as it can be.
# Step 1) You need sprites for the overworld pokemon in your \Graphics\Characters
# folder named by there number 001.png, 002.png, ...,
# with the corresponding shiny versions 001s.png, 002s.png, ....
# For instance you can use Gen 1-7 OV SPrites or whatever you want for 
# your fakemon
# If you want to use alternative forms as overworld sprites, then make sure that
# you also have a sprite for each alternative form, e. g. for Unown 201_1.png, 
# 201s_1.png, 201_2.png, 201s_2.png, ...
# If you want to use female forms as overworld sprites, then make sure that you 
# also have a female sprite for each pokemon named 001f.png, 001fs.png, 002f.png, 
# 002fs.png, ... (excluding genderless pokemon of course)
# Step 2) Insert a new file in the script editor above main,
# name it Overworld_Random_Encounters and copy this code into it. 
# 
# PROPERTIES:
# 1) If you want to have water encounters only while surfing,
# you also have to change the value of the
# upcoming parameter RESTRICTENCOUNTERSTOPLAYERMOVEMENT to
#     RESTRICTENCOUNTERSTOPLAYERMOVEMENT = true
# 2) You can choose how many steps the encounter moves before vanishing 
# in parameter
#     STEPSBEFOREVANISHING
# 3) You can choose how many encounters you have to kill to obtain the increased
# Shiny-Chance in parameter
#     CHAINLENGTH
# and the increased Shiny-Chance in parameter
#     SHINYPROBABILITY
# 4) You can choose whether the sprite of your overworld encounter
# is always the standard form or can be an alternative form in parameter
#     USEALTFORMS
# 5) You can choose whether the sprites depend on the gender of the encounter
# or are always neutral in parameter
#     USEFEMALESPRITES
# 6) You can choose whether the overworld encounters have a stop/ step-animation
# similar to following pokemon in the parameter
#     USESTOPANIMATION
# 7) You can choose how many overworld encounters are agressive and run to the 
# player in the parameter
#     AGGRESSIVEENCOUNTERPROBABILITY
# 8) You can choose the move-speed and move-frequenzy of  normal and aggressive 
# encounters in parameters
#     ENCMOVESPEED, ENCMOVEFREQ, AGGRENCMOVESPEED, AGGRENCMOVEFREQ
# 9) You can choose whether pokemon can spawn automatically or only while the 
# player is moving and you can set the spawning frequency in the parameter
#     AUTOSPAWNSPEED
# 10) You can activate or deactivate vendilys rescue chain by in the parameter 
#     USERESCUECHAIN
# Moreover, you also have all settings of vendilys Rescue chain here.
#
# THANKS to BulbasaurLvl5 for bringing me to pokemon essentials and the
# super productive time

RESTRICTENCOUNTERSTOPLAYERMOVEMENT = false
#true - means that water encounters are popping up
#       if and only if player is surfing
#       (perhaps decreases encounter rate)
#false - means that all encounter types can pop up
#        close to the player (as long as there is a suitable tile)

CHAINLENGTH      = 10 # default 10
#       number describes how many pokemon of the same species
#       you have to kill in a row to increase shiny propability

SHINYPROBABILITY = 100 # default 100 --> 10%
#       increasing this value decreases the probability of spawning a shiny

STEPSBEFOREVANISHING = 6 # default 10
#      STEPSBEFOREVANISHING is the number of steps a wild Encounter goes
#      before vanishing on the map.

USEALTFORMS = true # default false
#false - means that you don't use alternative forms for your overworld sprite
#true - means that the sprite of overworld encounter varies by the form of that pokemon
#       make sure that you have the sprites with the right name
#       for your alternative forms in your \Graphics\Characters folder       

USEFEMALESPRITES = true # default false
#false - means that you use always a neutral overworld sprite
#true - means that female pokemon have there own female overworld sprite
#       make sure that you have the sprites with the right name 001f.png,
#       001fs.png, ... for the female forms in your \Graphics\Characters folder

USESTOPANIMATION = true # default false
#false - means that overworld encounters don't have a stop- animation
#true - means that overworld encounters have a stop- animation similar as  
#       following pokemon

ENCMOVESPEED = 3 # default 3
# this is the movement speed (compare to autonomous movement of events) of an overworld encounter
#1   - means lowest movement
#6   - means highest movement

ENCMOVEFREQ = 3 # default 3
# this is the movement frequenzy (compare to autonomous movement of events) of an overworld encounter
#1   - means lowest movement
#6   - means highest movement

AGGRESSIVEENCOUNTERPROBABILITY = 20 # default 20 
#this is the probability in percent of spawning of an agressive encounter
#0   - means that there are no aggressive encounters
#100 - means that all encounter are aggressive

AGGRENCMOVESPEED = 3 # default 3

AUTOSPAWNSPEED = 0 # default 60
#You can set the speed of automatic pokemon spawning, i.e. the ability of pokemon
# to spawn automatically even without even moving the player.
#0   - means that pokemon only spawn while the player is moving
#>0  - means automatic spawning is activated, the closer to 0 the faster the spawning

USERESCUECHAIN = false # default false
#This parameter activates and deactivates vendilys rescue chain
#true  - means that fighting pokemon of the same speciesfamily in a row will increase the chance of spawning an evolved pokemon
#false - means that the rescue chain is deactivated

#Here the settings for Vendilys Rescue Chain
#    #===============================================================================
#    # Rescue Chain - By Vendily [v17]
#    # This script makes it so that if you chain pokemon of the same evolutionary
#    #  family together, an evolved form of the species will appear.
#    # I used no references and I completly misinterpreted a description of SOS
#    #  battles as this thing.
#    # * Minimum length of chain before evolved forms begin to appear. With every
#    #    multiple, the chance for the evolved form or a second evolved form to appear
#    #    increases. (Default 10)
#    # * Chance that the evolved form will even show up, 1 out of this constant.
#    #    (Default 4, for 1/4 chance, it's probably too high)
#    # * Random number added to the minimum level this pokemon can evolve at or
#    #    the wild pokemon's current level if it evolves through item (Default 5)
#    # * Disable this modifier while the pokeradar is being used.
#    #    I recommend leaving it as is as the pokeradar may behave strangely and the
#    #    two scripts may reset each others' chain. (Default true)
#    # * The maps where this effect can only take place in.
#    # * The maps where this effect will never happen. Ever.
#    # * The switch to disable this effect. (Default -1)

* Visible Overworld Wild Encounters Version 1.9 - by derFischae (Credits if used please) *

UPDATED TO VERSION 1.9. NOW INCLUDING VENDILYS RESCUE CHAIN AND DOWNSCALE OF VERSION 1.6 FOR POKEMON ESSENTIALS V16.2 BY ARCHYTHEARC.

This script is for Pokémon Essentials V16.2, V17 and V17.2. Originally written for V17 and 17.2 by me and VERSION 1.6 downscaled to V16.2 by ArchyTheArc.

As in Pokemon Let's go Pikachu/Eevee or Pokemon Shild and Sword random 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 INCLUDED:
- see the pokemon on the overworld before going into battle
- no forced battling against random encounters
- plays the pokemon cry while spawning
- Choose whether encounters occure on all terrains or only on the terrain of the player
- if you kill the same species in a row, then you increase the chance of spawning a shiny of that species or an evolved pokemon of that species family

NEW FEATURES IN VERSION 1.1:
- less lag
- supports sprites for alternative forms of pokemon

NEW FEATURES IN VERSION 1.2:
- supports sprites for female/male/genderless pokemon

NEW FEATURES IN VERSION 1.3:
- bug fixes for roaming encounter and double battles

NEW FEATURES IN VERSION 1.4:
- more options in settings

NEW FEATURES IN VERSION 1.5:
- roaming encounters working correctly

NEW FEATURES IN VERSION 1.6:
- did some runtime optimization, i.e. faster despawning of pokemon after battle

NEW FEATURES IN VERSION 1.7:
- included automatic spawening of pokemon, i.e. without spawning without having to move the player

NEW FEATURES IN VERSION 1.8:
- included vendilys rescue chain, i. e. if pokemon of the same species family spawn in a row and will be battled in a row, then you increase the chance of spawning an evolved pokemon of that species family. Link: https://www.pokecommunity.com/threads/415524

NEW FEATURES IN VERSION 1.9:
- removed bug occuring after fainting against wild overworld encounter
- for script-developers, shortened the spawnEvent method for better readablitiy

INSTALLATION:
Installation as simple as it can be.
Step 1) You need sprites for the overworld pokemon in your \Graphics\Characters folder named by there number 001.png, 002.png, ..., with the corresponding shiny versions 001s.png, 002s.png, .... For instance you can use Gen 1-7 OV SPrites or whatever you want for your fakemon.
If you want to use alternative forms as overworld sprites, then make sure that you also have a sprite for each alternative form, e. g. for Unown 201_1.png, 201s_1.png, 201_2.png, 201s_2.png, ...
If you want to use female forms as overworld sprites, then make sure that you also have a female sprite for each pokemon named 001f.png, 001fs.png, 002f.png, 002fs.png, ... (excluding genderless pokemon of course)
Step 2) Insert a new file in the script editor above main, name it Overworld_Random_Encounters and copy this code into it.

PROPERTIES:
1) If you want to have water encounters only while surfing, you also have to change the value of the upcoming parameter RESTRICTENCOUNTERSTOPLAYERMOVEMENT to
RESTRICTENCOUNTERSTOPLAYERMOVEMENT = true
2) You can choose how many steps the encounter moves before vanishing in parameter
STEPSBEFOREVANISHING
3) You can choose how many encounters you have to kill to obtain the increased Shiny-Chance in parameter
CHAINLENGTH
and the increased Shiny-Chance in parameter
SHINYPROBABILITY
4) You can choose whether the sprite of your overworld encounter is always the standard form or can be an alternative form in parameter
USEALTFORMS
5) You can choose whether the sprites depend on the gender of the encounter or are always neutral in parameter
USEFEMALESPRITES
6) You can choose whether the overworld encounters have a stop/ step-animation similar to following pokemon in the parameter
USESTOPANIMATION
7) You can choose how many overworld encounters are agressive and run to the player in the parameter
AGGRESSIVEENCOUNTERPROBABILITY
8) You can choose the move-speed and move-frequenzy of normal and aggressive encounters in parameters
ENCMOVESPEED, ENCMOVEFREQ, AGGRENCMOVESPEED, AGGRENCMOVEFREQ
9) You can choose whether pokemon can spawn automatically or only while the player is moving and you can set the spawning frequency in the parameter
AUTOSPAWNSPEED
10) You can activate or deactivate vendilys rescue chain by in the parameter
USERESCUECHAIN
Moreover, you also have all settings of vendilys Rescue chain here.

THANKS to BulbasaurLvl5 for bringing me to pokemon essentials and the super productive time

THANKS to ArchyTheArc for downscaling to Pokemon Essentials V16.2.

#    # Rescue Chain - By Vendily [v17]
#    # This script makes it so that if you chain pokemon of the same evolutionary
#    #  family together, an evolved form of the species will appear.
#    # I used no references and I completly misinterpreted a description of SOS
#    #  battles as this thing.
#    # * Minimum length of chain before evolved forms begin to appear. With every
#    #    multiple, the chance for the evolved form or a second evolved form to appear
#    #    increases. (Default 10)
#    # * Chance that the evolved form will even show up, 1 out of this constant.
#    #    (Default 4, for 1/4 chance, it's probably too high)
#    # * Random number added to the minimum level this pokemon can evolve at or
#    #    the wild pokemon's current level if it evolves through item (Default 5)
#    # * Disable this modifier while the pokeradar is being used.
#    #    I recommend leaving it as is as the pokeradar may behave strangely and the
#    #    two scripts may reset each others' chain. (Default true)
#    # * The maps where this effect can only take place in.
#    # * The maps where this effect will never happen. Ever.
#    # * The switch to disable this effect. (Default -1)

Spoiler:

#===============================================================================
# * Visible Overworld Encounters V1.6 - by derFischae (Credits if used please) *
# * V1.6 Downscale to V16.2 - by ArchyTheArc*
#===============================================================================
#
# UPDATED TO VERSION 1.6
#
# This script is for Pokémon Essentials V16.2. Downscale by ArchyTheArc.
# As in Pokemon Let's go Pikachu/Eevee or Pokemon Shild and Sword
# random 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 INCLUDED:
#   - see the pokemon on the overworld before going into battle
#   - no forced battling against random encounters
#   - plays the pokemon cry while spawning
#   - Choose whether encounters occure on all terrains or only on 
#     the terrain of the player
#   - if you kill the same species in a row, then you increase
#     the chance of spawning a shiny of that species 
#
# NEW FEATURES IN VERSION 1.1:
#   - less lag
#   - supports sprites for alternative forms of pokemon
#
# NEW FEATURES IN VERSION 1.2:
#   - supports sprites for female/male/genderless pokemon
#
# NEW FEATURES IN VERSION 1.3:
#   - bug fixes for roaming encounter and double battles
#
# NEW FEATURES IN VERSION 1.4:
#   - more options in settings
#
# NEW FEATURES IN VERSION 1.5:
#   - roaming encounters working correctly
#
# NEW FEATURES IN VERSION 1.6:
#   - more lag reduction 
#
# INSTALLATION:
# Installation as simple as it can be.
# Step 1) You need sprites for the overworld pokemon in your \Graphics\Characters
# folder named by there number 001.png, 002.png, ...,
# with the corresponding shiny versions 001s.png, 002s.png, ....
# For instance you can use Gen 1-7 OV SPrites or whatever you want for 
# your fakemon
# If you want to use alternative forms as overworld sprites, then make sure that
# you also have a sprite for each alternative form, e. g. for Unown 201_1.png, 
# 201s_1.png, 201_2.png, 201s_2.png, ...
# If you want to use female forms as overworld sprites, then make sure that you 
# also have a female sprite for each pokemon named 001f.png, 001fs.png, 002f.png, 
# 002fs.png, ... (excluding genderless pokemon of course)
# Step 2) Insert a new file in the script editor above main,
# name it Overworld_Random_Encounters and copy this code into it. 
# 
# PROPERTIES:
# 1) If you want to have water encounters only while surfing,
# you also have to change the value of the
# upcoming parameter RESTRICTENCOUNTERSTOPLAYERMOVEMENT to
#     RESTRICTENCOUNTERSTOPLAYERMOVEMENT = true
# 2) You can choose how many steps the encounter moves before vanishing 
# in parameter
#     STEPSBEFOREVANISHING
# 3) You can choose how many encounters you have to kill to obtain the increased
# Shiny-Chance in parameter
#     CHAINLENGTH
# and the increased Shiny-Chance in parameter
#     SHINYPROBABILITY
# 4) You can choose whether the sprite of your overworld encounter
# is always the standard form or can be an alternative form in parameter
#     USEALTFORMS
# 5) You can choose whether the sprites depend on the gender of the encounter
# or are always neutral in parameter
#     USEFEMALESPRITES
# 6) You can choose whether the overworld encounters have a stop/ step-animation
# similar to following pokemon in the parameter
#     USESTOPANIMATION
# 7) You can choose how many overworld encounters are agressive and run to the 
# player in the parameter
#     AGGRESSIVEENCOUNTERPROBABILITY
# 8) You can choose the move-speed and move-frequenzy of  normal and aggressive 
# encounters in parameters
#     ENCMOVESPEED, ENCMOVEFREQ, AGGRENCMOVESPEED, AGGRENCMOVEFREQ

Maybe, you also need this for Pokemon Essentials 16.2:

Spoiler:

module PBTerrain
  TallGrass       = 10
  def PBTerrain.isDoubleGrass?(tag)
    return tag==PBTerrain::TallGrass
  end
end

I have one last proposal for you.
Can we introduce the chances that the pokémon you're looking for will have the MAX IVs or that it has its hidden ability?
I think it will complement the script.

PS: With your latest updates, the pokémon's shape doesn't appear. This is the standard form that appears.

Thank you in advance.

Hi, I'm using the 17.2 version of pokemon essentials and the 16.2 version of your script because the 17.2 version didn't work correctly for me. the error does not happen when I combat a wild pokemon without your script. About the missing terrain tags i added those in PBTerrain. I had some of them missing like TallGrass or Waterfall.
#===============================================================================
# Terrain tags
#===============================================================================

Ledge = 1
Grass = 2

Rock = 4
DeepWater = 5
StillWater = 6

TallGrass = 10
UnderwaterGrass = 11
Ice = 12
Neutral = 13
SootGrass = 14
Bridge = 15
Puddle = 16
Puddle = 17

Well, now there appears to be a different bug, it seems to be random, so I can't pinpoint it, but it happens when I'm simply walking around in grassy areas.
It looks to be similar to last time, but in a different area. Using the latest version again. (1.9)

Exception: NameError

PS: With your latest updates, the pokémon's shape doesn't appear. This is the standard form that appears.

Thank you in advance.

Well, now there appears to be a different bug, it seems to be random, so I can't pinpoint it, but it happens when I'm simply walking around in grassy areas.
It looks to be similar to last time, but in a different area. Using the latest version again. (1.9)

Thanks for your remarks. Should be fixed now, in the following version 1.9.1

Spoiler:

#===============================================================================
# * Visible Overworld Encounters V1.9.1 - by derFischae (Credits if used please) *
#===============================================================================
#
# UPDATED TO VERSION 1.9.1
#
# This script is for Pokémon Essentials 17.
# As in Pokemon Let's go Pikachu/Eevee or Pokemon Shild and Sword
# random 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 INCLUDED:
#   - see the pokemon on the overworld before going into battle
#   - no forced battling against random encounters
#   - plays the pokemon cry while spawning
#   - Choose whether encounters occure on all terrains or only on 
#     the terrain of the player
#   - if you kill the same species in a row, then you increase
#     the chance of spawning a shiny of that species or an evolved pokemon of that species family
#
# NEW FEATURES IN VERSION 1.1:
#   - less lag
#   - supports sprites for alternative forms of pokemon
#
# NEW FEATURES IN VERSION 1.2:
#   - supports sprites for female/male/genderless pokemon
#
# NEW FEATURES IN VERSION 1.3:
#   - bug fixes for roaming encounter and double battles
#
# NEW FEATURES IN VERSION 1.4:
#   - more options in settings
#
# NEW FEATURES IN VERSION 1.5:
#   - roaming encounters working correctly
#
# NEW FEATURES IN VERSION 1.6:
#   - more lag reduction 
#
# NEW FEATURES IN VERSION 1.7:
#   - included automatic spawning of pokemon, i.e. without spawning without having to move the player
#
# NEW FEATURES IN VERSION 1.8:
#   - included vendilys rescue chain, i. e. if pokemon of the same species family spawn in a row and will be battled in a row, then you increase the chance of spawning
#     an evolved pokemon of that species family. Link: https://www.pokecommunity.com/showthread.php?t=415524
#
# NEW FEATURES IN VERSION 1.9:
#   - removed bug occuring after fainting against wild overworld encounter
#   - for script-developers, shortened the spawnEvent method for better readablitiy
#
# NEW FEATURES IN VERSION 1.9.1:
#   - removed bug from version 1.9
#   - added shapes of overworld encounter for rescue chain users
#
# INSTALLATION:
# Installation as simple as it can be.
# Step 1) You need sprites for the overworld pokemon in your \Graphics\Characters
# folder named by there number 001.png, 002.png, ...,
# with the corresponding shiny versions 001s.png, 002s.png, ....
# For instance you can use Gen 1-7 OV SPrites or whatever you want for 
# your fakemon
# If you want to use alternative forms as overworld sprites, then make sure that
# you also have a sprite for each alternative form, e. g. for Unown 201_1.png, 
# 201s_1.png, 201_2.png, 201s_2.png, ...
# If you want to use female forms as overworld sprites, then make sure that you 
# also have a female sprite for each pokemon named 001f.png, 001fs.png, 002f.png, 
# 002fs.png, ... (excluding genderless pokemon of course)
# Step 2) Insert a new file in the script editor above main,
# name it Overworld_Random_Encounters and copy this code into it. 
# 
# PROPERTIES:
# 1) If you want to have water encounters only while surfing,
# you also have to change the value of the
# upcoming parameter RESTRICTENCOUNTERSTOPLAYERMOVEMENT to
#     RESTRICTENCOUNTERSTOPLAYERMOVEMENT = true
# 2) You can choose how many steps the encounter moves before vanishing 
# in parameter
#     STEPSBEFOREVANISHING
# 3) You can choose how many encounters you have to kill to obtain the increased
# Shiny-Chance in parameter
#     CHAINLENGTH
# and the increased Shiny-Chance in parameter
#     SHINYPROBABILITY
# 4) You can choose whether the sprite of your overworld encounter
# is always the standard form or can be an alternative form in parameter
#     USEALTFORMS
# 5) You can choose whether the sprites depend on the gender of the encounter
# or are always neutral in parameter
#     USEFEMALESPRITES
# 6) You can choose whether the overworld encounters have a stop/ step-animation
# similar to following pokemon in the parameter
#     USESTOPANIMATION
# 7) You can choose how many overworld encounters are agressive and run to the 
# player in the parameter
#     AGGRESSIVEENCOUNTERPROBABILITY
# 8) You can choose the move-speed and move-frequenzy of  normal and aggressive 
# encounters in parameters
#     ENCMOVESPEED, ENCMOVEFREQ, AGGRENCMOVESPEED, AGGRENCMOVEFREQ
# 9) You can choose whether pokemon can spawn automatically or only while the 
# player is moving and you can set the spawning frequency in the parameter
#     AUTOSPAWNSPEED
# 10) You can activate or deactivate vendilys rescue chain by in the parameter 
#     USERESCUECHAIN
# Moreover, you also have all settings of vendilys Rescue chain here.
#
# THANKS to BulbasaurLvl5 for bringing me to pokemon essentials and the
# super productive time

RESTRICTENCOUNTERSTOPLAYERMOVEMENT = false
#true - means that water encounters are popping up
#       if and only if player is surfing

#false - means that all encounter types can pop up
#        close to the player (as long as there is a suitable tile)

CHAINLENGTH      = 10 # default 10
#       number describes how many pokemon of the same species
#       you have to kill in a row to increase shiny propability

SHINYPROBABILITY = 100 # default 100 --> 10%
#       increasing this value decreases the probability of spawning a shiny

STEPSBEFOREVANISHING = 6 # default 10
#      STEPSBEFOREVANISHING is the number of steps a wild Encounter goes
#      before vanishing on the map.

USEALTFORMS = true # default false
#false - means that you don't use alternative forms for your overworld sprite
#true - means that the sprite of overworld encounter varies by the form of that pokemon
#       make sure that you have the sprites with the right name
#       for your alternative forms in your \Graphics\Characters folder       

USEFEMALESPRITES = true # default false
#false - means that you use always a neutral overworld sprite
#true - means that female pokemon have there own female overworld sprite

#true - means that overworld encounters have a stop- animation similar as  
#       following pokemon

ENCMOVESPEED = 3 # default 3
# this is the movement speed (compare to autonomous movement of events) of an overworld encounter
#1   - means lowest movement
#6   - means highest movement

ENCMOVEFREQ = 3 # default 3

#1   - means lowest movement
#6   - means highest movement

AGGRESSIVEENCOUNTERPROBABILITY = 20 # default 20

AUTOSPAWNSPEED = 0 # default 60
#You can set the speed of automatic pokemon spawning, i.e. the ability of pokemon
# to spawn automatically even without even moving the player.
#0   - means that pokemon only spawn while the player is moving
#>0  - means automatic spawning is activated, the closer to 0 the faster the spawning

USERESCUECHAIN = false # default false
#This parameter activates and deactivates vendilys rescue chain
#true  - means that fighting pokemon of the same speciesfamily in a row will increase the chance of spawning an evolved pokemon
#false - means that the rescue chain is deactivated

#    #===============================================================================
#    # Rescue Chain - By Vendily [v17]
#    # This script makes it so that if you chain pokemon of the same evolutionary
#    #  family together, an evolved form of the species will appear.
#    # I used no references and I completly misinterpreted a description of SOS
#    #  battles as this thing.
#    # * Minimum length of chain before evolved forms begin to appear. With every
#    #    multiple, the chance for the evolved form or a second evolved form to appear
#    #    increases. (Default 10)
#    # * Chance that the evolved form will even show up, 1 out of this constant.
#    #    (Default 4, for 1/4 chance, it's probably too high)
#    # * Random number added to the minimum level this pokemon can evolve at or
#    #    the wild pokemon's current level if it evolves through item (Default 5)
#    # * Disable this modifier while the pokeradar is being used.
#    #    I recommend leaving it as is as the pokeradar may behave strangely and the
#    #    two scripts may reset each others' chain. (Default true)
#    # * The maps where this effect can only take place in.
#    # * The maps where this effect will never happen. Ever.
#    # * The switch to disable this effect. (Default -1)

[derFischae]

Hi, I'm using the 17.2 version of pokemon essentials and the 16.2 version of your script because the 17.2 version didn't work correctly for me. the error does not happen when I combat a wild pokemon without your script. About the missing terrain tags i added those in PBTerrain. I had some of them missing like TallGrass or Waterfall.
#===============================================================================
# Terrain tags
#===============================================================================
module PBTerrain
Ledge = 1
Grass = 2
Sand = 3
Rock = 4
DeepWater = 5
StillWater = 6
Water = 7
Waterfall = 8
WaterfallCrest = 9
TallGrass = 10
UnderwaterGrass = 11
Ice = 12
Neutral = 13
SootGrass = 14
Bridge = 15
Puddle = 16
Puddle = 17

It is not recommanded to use the visible wild overworld encounter script version for Pokemon Essentials 16.2 while using Pokemon Essentials 17.2.
The older versions were buggy. Please try the newest version 1.9.1. Probabily, it will work for you now.

Spoiler:

#===============================================================================
# * Visible Overworld Encounters V1.9.1 - by derFischae (Credits if used please) *
#===============================================================================
#
# UPDATED TO VERSION 1.9.1
#
# This script is for Pokémon Essentials 17.
# As in Pokemon Let's go Pikachu/Eevee or Pokemon Shild and Sword
# random 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 INCLUDED:
#   - see the pokemon on the overworld before going into battle
#   - no forced battling against random encounters
#   - plays the pokemon cry while spawning
#   - Choose whether encounters occure on all terrains or only on 
#     the terrain of the player
#   - if you kill the same species in a row, then you increase
#     the chance of spawning a shiny of that species or an evolved pokemon of that species family
#
# NEW FEATURES IN VERSION 1.1:
#   - less lag
#   - supports sprites for alternative forms of pokemon
#
# NEW FEATURES IN VERSION 1.2:
#   - supports sprites for female/male/genderless pokemon
#
# NEW FEATURES IN VERSION 1.3:
#   - bug fixes for roaming encounter and double battles
#
# NEW FEATURES IN VERSION 1.4:
#   - more options in settings
#
# NEW FEATURES IN VERSION 1.5:
#   - roaming encounters working correctly
#
# NEW FEATURES IN VERSION 1.6:
#   - more lag reduction 
#
# NEW FEATURES IN VERSION 1.7:
#   - included automatic spawning of pokemon, i.e. without spawning without having to move the player
#
# NEW FEATURES IN VERSION 1.8:
#   - included vendilys rescue chain, i. e. if pokemon of the same species family spawn in a row and will be battled in a row, then you increase the chance of spawning
#     an evolved pokemon of that species family. Link: https://www.pokecommunity.com/showthread.php?t=415524
#
# NEW FEATURES IN VERSION 1.9:
#   - removed bug occuring after fainting against wild overworld encounter
#   - for script-developers, shortened the spawnEvent method for better readablitiy
#
# NEW FEATURES IN VERSION 1.9.1:
#   - removed bug from version 1.9
#   - added shapes of overworld encounter for rescue chain users
#
# INSTALLATION:
# Installation as simple as it can be.
# Step 1) You need sprites for the overworld pokemon in your \Graphics\Characters
# folder named by there number 001.png, 002.png, ...,
# with the corresponding shiny versions 001s.png, 002s.png, ....
# For instance you can use Gen 1-7 OV SPrites or whatever you want for 
# your fakemon
# If you want to use alternative forms as overworld sprites, then make sure that
# you also have a sprite for each alternative form, e. g. for Unown 201_1.png, 
# 201s_1.png, 201_2.png, 201s_2.png, ...
# If you want to use female forms as overworld sprites, then make sure that you 
# also have a female sprite for each pokemon named 001f.png, 001fs.png, 002f.png, 
# 002fs.png, ... (excluding genderless pokemon of course)
# Step 2) Insert a new file in the script editor above main,
# name it Overworld_Random_Encounters and copy this code into it. 
# 
# PROPERTIES:
# 1) If you want to have water encounters only while surfing,
# you also have to change the value of the
# upcoming parameter RESTRICTENCOUNTERSTOPLAYERMOVEMENT to
#     RESTRICTENCOUNTERSTOPLAYERMOVEMENT = true
# 2) You can choose how many steps the encounter moves before vanishing 
# in parameter
#     STEPSBEFOREVANISHING
# 3) You can choose how many encounters you have to kill to obtain the increased
# Shiny-Chance in parameter
#     CHAINLENGTH
# and the increased Shiny-Chance in parameter
#     SHINYPROBABILITY
# 4) You can choose whether the sprite of your overworld encounter
# is always the standard form or can be an alternative form in parameter
#     USEALTFORMS
# 5) You can choose whether the sprites depend on the gender of the encounter
# or are always neutral in parameter
#     USEFEMALESPRITES
# 6) You can choose whether the overworld encounters have a stop/ step-animation
# similar to following pokemon in the parameter
#     USESTOPANIMATION
# 7) You can choose how many overworld encounters are agressive and run to the 
# player in the parameter
#     AGGRESSIVEENCOUNTERPROBABILITY
# 8) You can choose the move-speed and move-frequenzy of  normal and aggressive 
# encounters in parameters
#     ENCMOVESPEED, ENCMOVEFREQ, AGGRENCMOVESPEED, AGGRENCMOVEFREQ
# 9) You can choose whether pokemon can spawn automatically or only while the 
# player is moving and you can set the spawning frequency in the parameter
#     AUTOSPAWNSPEED
# 10) You can activate or deactivate vendilys rescue chain by in the parameter 
#     USERESCUECHAIN
# Moreover, you also have all settings of vendilys Rescue chain here.
#
# THANKS to BulbasaurLvl5 for bringing me to pokemon essentials and the
# super productive time

#    #===============================================================================
#    # Rescue Chain - By Vendily [v17]
#    # This script makes it so that if you chain pokemon of the same evolutionary
#    #  family together, an evolved form of the species will appear.
#    # I used no references and I completly misinterpreted a description of SOS
#    #  battles as this thing.
#    # * Minimum length of chain before evolved forms begin to appear. With every
#    #    multiple, the chance for the evolved form or a second evolved form to appear
#    #    increases. (Default 10)
#    # * Chance that the evolved form will even show up, 1 out of this constant.
#    #    (Default 4, for 1/4 chance, it's probably too high)
#    # * Random number added to the minimum level this pokemon can evolve at or
#    #    the wild pokemon's current level if it evolves through item (Default 5)
#    # * Disable this modifier while the pokeradar is being used.
#    #    I recommend leaving it as is as the pokeradar may behave strangely and the
#    #    two scripts may reset each others' chain. (Default true)
#    # * The maps where this effect can only take place in.
#    # * The maps where this effect will never happen. Ever.
#    # * The switch to disable this effect. (Default -1)

If your error still occurs, then please post the error message (and use the CODE brackets for better readability) and let us know what you did ingame before the error occurs.

Concerning your adding of Terrain tags: It does not seem to be correct, that you have Puddle twice in the enumeration, I guess.

module PBTerrain
  [...]
  Puddle          = 16
  Puddle          = 17

I have one last proposal for you.
Can we introduce the chances that the pokémon you're looking for will have the MAX IVs or that it has its hidden ability?
I think it will complement the script.

Thank you in advance.

Can you please explain more precisely what you mean? Do you mean that we simply code that every 10th, 50th... encounter automatically has MAX IVs? Or do you what a catch or kill combo which increases the IVs of the encounter of the same type?

It is true that the method to meet the Pokemon sought with the IVs is not well defined.
In fact it's up to you to choose what's best for you.
I personally think you have to model yourself on the Rescue Chain script - By Vendily.
That is, the more we hunt the same Pokémon, the more the chance to see the MAX IVs or hidden ability appears.
A can like the S.O.S battle method.

What do you think?

If you have another solution...

But I think this should be added to the Rescue Chain script - By Vendily rather than in yours.

Your script is made to make wild Pokémon appear on the map.

Adding max IVs and hidden ability are just options that need to be in another script.
The one from Rescue Chain - By Vendily for example.

It's an option.
It's up to you to see if it needs to be added.

Right now I'm looking for a script to mimic the S.O.S battle scene like in Pokemon Sun and Moon, I'm looking for a script for the battle hordes and finally a script to show the size and weight of the pokemon captured as in Pokemon Let's Go.

All this is work and it takes a lot of time.
I hope I can make them happen.

Tanks!
(sorry for my English)

Have you done any modifications on the overworld wild encounters script? Have you installed other scripts? Well, I'm sure you did. So, it seems that you use a script, which is not compatible with the overworld wild encounter script. Or you changed something unintentionally.

Can you please send me all lines from the 334th line to the 340th line of your script "Overworld_Random_Encounters". Please, also search every script in the editor for the following code:

def pbCanEncounter?

and post every result. I'm interested in the words that stand in backets behind that "def pbCanEncounter?( ... )" and I want to know the script name (i. e. in the left column) for each result.

I predict that there will be at least one searching result where there is only one word in brackets.

    end
    return true
  end

It seems, that you are not using the current Pokemon Essentials version 17.2.

The code for pbCanEncounter? in the script "PField_Encounters" should be the following instead:

  def pbCanEncounter?(encounter,repel)
    return false if $game_system.encounter_disabled
    return false if !encounter || !$Trainer
    return false if $DEBUG && Input.press?(Input::CTRL)
    if !pbPokeRadarOnShakingGrass
      return false if ($PokemonGlobal.repel>0 || repel) &&
                      $Trainer.firstAblePokemon &&
                      encounter[1]<$Trainer.firstAblePokemon.level
    end
    return true
  end

Replace all of your "pbCanEncounter?(encounter)" method by the code I posted above. If it still doesn't work, then you will have to update your pokemon essentials version or search for help in other threads about that issue. Your problems don't come from my overworld wild encounter script. So I can't help you here in future.

I can't help you with Pokemon Essentials 16.2, since I don't have it. Use 17.2 or learn to code and optimize the script for your outdated version. Good luck and study hard.

 

[DonutDoctor10]

For some reason, Scatterbug's overworld sprite won't show up when it spawns, even though I have its overworld sprites in the Characters folder. Do you know how I can fix this?

 

[wells]

I'll try it! Thanks for your time!

 

[derFischae]

For some reason, Scatterbug's overworld sprite won't show up when it spawns, even though I have its overworld sprites in the Characters folder. Do you know how I can fix this?

Normally Scatterbug has 18 alternative forms. But you will only see one form depending on your trainerID.
if you disable alternative forms in the settings, then it will work correctly.
If you want to use alternative forms, then you also have to include 664_1.png, ..., 664_19.png and 664s_1.png, ..., 664s_19.png. Then it will show the alternative forms.

Edit: You can simply copy and rename 664.png and 664s.png. Same is true for Pokemon with number 665 and 666.

 

[Luxintra]

Is it possible to get this scrip to work with EncounterModifiers? As currently it will only spawn the overworld sprite for whatever is in the maps encounter list.
