In Sprite_Character, in def update add the red parts

Spoiler:

        self.src_rect.set(sx, sy, @cw, @ch)
      end

then (same section) under def character_name add the red part

Spoiler:

In PokeBattle_ActualScene add the red part
This just allows you to have a lava base during battles

Spoiler:

elsif $PokemonGlobal.surfing
      trialname="Water"
[COLOR="red"]elsif $PokemonGlobal.lavasurfing

In PokemonField, under module PBTerrain, add the red part

Spoiler:

Bridge          = 15
  Lava            = 16

16 can be a different number if you've added other tiles. As long as it's defined separately from other tiles.

Right after this module ends, add

Spoiler:

def pbIsPassableLavaTag?(tag)
  return tag==PBTerrain::Lava
end

Same section, add the red part to def Kernel.pbUpdateVehicle

Spoiler:

In PokemonMap under class PokemonGlobalMetadata, add the red part

Spoiler:

attr_accessor :surfing
  [COLOR="red"]attr_accessor :lavasurfing[/COLOR]

Slightly lower under def initialize, add the red part

Spoiler:

@surfing              = false
    [COLOR="red"]@lavasurfing          = false[/COLOR]

Lastly, same section, under Module PokemonMetadata replace this part

Spoiler:

GlobalTypes={
     "Home"=>[MetadataHome,"uuuu"],
     "WildBattleBGM"=>[MetadataWildBattleBGM,"s"],
     "TrainerBattleBGM"=>[MetadataTrainerBattleBGM,"s"],
     "WildVictoryME"=>[MetadataWildVictoryME,"s"],
     "TrainerVictoryME"=>[MetadataTrainerVictoryME,"s"],
     "SurfBGM"=>[MetadataSurfBGM,"s"],
     "BicycleBGM"=>[MetadataBicycleBGM,"s"],
     "PlayerA"=>[MetadataPlayerA,"esssssssss",:PBTrainers], 
     "PlayerB"=>[MetadataPlayerB,"esssssssss",:PBTrainers],
     "PlayerC"=>[MetadataPlayerC,"esssssssss",:PBTrainers],
     "PlayerD"=>[MetadataPlayerD,"esssssssss",:PBTrainers],
     "PlayerE"=>[MetadataPlayerE,"esssssssss",:PBTrainers],
     "PlayerF"=>[MetadataPlayerF,"esssssssss",:PBTrainers],
     "PlayerG"=>[MetadataPlayerG,"esssssssss",:PBTrainers],
     "PlayerH"=>[MetadataPlayerH,"esssssssss",:PBTrainers]
  }

And that's all the coding part. Three other things you will need to do.
1. Add Lava Surf as a move to moves.txt

Spoiler:

560,LAVASURF,Lava Surf,075,95,FIRE,Special,100,15,0,08,0,bef,"It swamps the area around the user with a giant wave of molten rock. It can also be used for crossing lava."

2. Add a filepath for each character in your metadata.txt (red part is the addition)
I'm just using the default surfing graphic, you can use a special graphic or whatever

Spoiler:

PlayerA=POKEMONTRAINER_Red,trchar000,boy_bike,boy_surf_offset,boy_run,boy_dive_offset,boy_fish_offset,boy_fishsurf_offset[COLOR="red"],boy_surf_offset[/COLOR][COLOR="red"],boy_fishsurf_offset[/COLOR]
PlayerB=POKEMONTRAINER_Leaf,trchar001,girl_bike,girl_surf_offset,girl_run,girl_dive_offset,girl_fish_offset,girl_fishsurf_offset[COLOR="red"],girl_surf_offset,girl_fishsurf_offset[/COLOR]

3. Just like with bridges, you'll have to add the terrain tag to lava tiles through the Editor. Otherwise they won't be seen as lava tags. Don't forget that the terrain tag has to be added to the tile individually on each tileset.

4. (Optional) Make Lava Surf a tm/hm move. I didn't provide this, but you can just basically copy surf and rename it.

I've provided a 4th gen style lava autotile you can use (credit to rayquaza_dot)

Note that while this allows for the graphics to change and work for fishing, this does not enable fishing while lava surfing, because I think that's just silly.
Tutorial is written for v15, untested for previous versions.

 

[kcgcrazy]

thank you so much for making this, i tried doing this myself but i just couldnt get it to work properly, ill deff try this out when i can!

 

[Radical Raptr]

That's gen 4 style lava - regardless, its a nice tutorial, I didn't realize theres so much that goes into it, hahah, good work.

 

[Qosole]

What terrain tag should the lava be? Also, how do you change the surf sprite and the lava surf sprite?

 

[mej71]

Terrain tag can be whatever unused number, just be consistent. The sprite used will be defined in your metadata.txt. I've mentioned these in the main post, please read thoroughly before asking questions.

I found an unused terrain tag, but how do you make it for lava surfing?

Did you read the OP?

"In PokemonField, under module PBTerrain, add the red part

Bridge          = 15
Lava            = 16

16 can be a different number if you've added other tiles. As long as it's defined separately from other tiles."

Not what I meant. In the database, there are only 7 terrain tags. How do you set it to 16?

 

[Florio]

Not what I meant. In the database, there are only 7 terrain tags. How do you set it to 16?

You have to go into the Pokemon Essentials Editor. From there you can change the Terrain Tag from 0-99

I changed it, but it doesn't prompt me to lava surf.

 

[Ulithium_Dragon]

Thanks for the guide!

I had a bit of a hard time following it though since Pokemon Essentials has changed so much since it was written (and like, all of the script sections got renamed for some reason...).

----
Anyways, I wanted some custom assets to use with lava surfing though, so I went ahead and made an autotile of the Gen III lava assets from R/S/E, as well as custom lava surf and lava fish-surf sprites for the male and female PC.

I'm gonna upload em here in case anyone else wants to use em! ;3

        self.src_rect.set(sx, sy, @cw, @ch)

In Walk_Run add the red part to pbCanRun?

Spoiler:

def pbCanRun?
    terrain=pbGetTerrainTag
    return Input.press?(Input::A) &&
       !pbMapInterpreterRunning? && !@move_route_forcing &&

       !$PokemonGlobal.bicycle && terrain!=PBTerrain::TallGrass &&
       terrain!=PBTerrain::Ice [COLOR="red"]&& !$PokemonGlobal.lavasurfing[/COLOR]
  end

then (same section) under def character_name add the red part

Spoiler:

if $PokemonGlobal.playerID>=0 && meta && 
         !$PokemonGlobal.bicycle && !$PokemonGlobal.diving && !$PokemonGlobal.surfing[COLOR="red"] && !$PokemonGlobal.lavasurfing[/COLOR]

          # Display normal character sprite 
          @character_name=pbGetPlayerCharset(meta,1)
        end
      end

In PokeBattle_ActualScene add the red part
This just allows you to have a lava base during battles

Spoiler:

elsif $PokemonGlobal.surfing
      trialname="Water"
[COLOR="red"]elsif $PokemonGlobal.lavasurfing
      trialname="Lava"[/COLOR]

In PokemonField, under module PBTerrain, add the red part

Spoiler:

Bridge          = 15
  Lava            = 16

16 can be a different number if you've added other tiles. As long as it's defined separately from other tiles.

Right after this module ends, add

Spoiler:

def pbIsPassableLavaTag?(tag)
  return tag==PBTerrain::Lava
end

Same section, add the red part to def Kernel.pbUpdateVehicle

Spoiler:

def Kernel.pbUpdateVehicle
  meta=pbGetMetadata(0,MetadataPlayerA+$PokemonGlobal.playerID)
  if meta
    if $PokemonGlobal.diving
      $game_player.character_name=pbGetPlayerCharset(meta,5) # Diving graphic

    else
      $game_player.character_name=pbGetPlayerCharset(meta,1) # Regular graphic
    end
  end
end

Next add the red part to def Kernel.pbCancelVehicle

Spoiler:

def Kernel.pbCancelVehicles(destination=nil)
  $PokemonGlobal.surfing=false
  $PokemonGlobal.diving=false
  [COLOR="red"]$PokemonGlobal.lavasurfing=false[/COLOR]
  if !destination || !pbCanUseBike?(destination)
    $PokemonGlobal.bicycle=false
  end
  Kernel.pbUpdateVehicle
end

Replace def pbFishingBegin and def pbFishingEnd

Spoiler:

def pbFishingBegin
  $PokemonGlobal.fishing=true
  if !pbCommonEvent(FISHINGBEGINCOMMONEVENT)
    patternb = 2*$game_player.direction - 1

          Graphics.update
          Input.update
          pbUpdateSceneMap

    meta=pbGetMetadata(0,MetadataPlayerA+$PokemonGlobal.playerID)
    num=($PokemonGlobal.surfing) ? 7 : ($PokemonGlobal.lavasurfing)? 9 : 6
    if meta && meta[num] && meta[num]!=""
      charset=pbGetPlayerCharset(meta,num)
      4.times do |pattern|
        $game_player.setDefaultCharName(charset,patternb+pattern)
        2.times do
          Graphics.update
          Input.update
          pbUpdateSceneMap
        end
      end
    end
  end
  $PokemonGlobal.fishing=false
end

Between the sections for Surf and Waterfall in PokemonHiddenMoves, add this whole thing

In PokemonMap under class PokemonGlobalMetadata, add the red part

Spoiler:

attr_accessor :surfing
  [COLOR="red"]attr_accessor :lavasurfing[/COLOR]

Slightly lower under def initialize, add the red part

Spoiler:

@surfing              = false
    [COLOR="red"]@lavasurfing          = false[/COLOR]

Lastly, same section, under Module PokemonMetadata replace this part

Spoiler:

GlobalTypes={
     "Home"=>[MetadataHome,"uuuu"],
     "WildBattleBGM"=>[MetadataWildBattleBGM,"s"],
     "TrainerBattleBGM"=>[MetadataTrainerBattleBGM,"s"],
     "WildVictoryME"=>[MetadataWildVictoryME,"s"],
     "TrainerVictoryME"=>[MetadataTrainerVictoryME,"s"],
     "SurfBGM"=>[MetadataSurfBGM,"s"],
     "BicycleBGM"=>[MetadataBicycleBGM,"s"],
     "PlayerA"=>[MetadataPlayerA,"esssssssss",:PBTrainers], 
     "PlayerB"=>[MetadataPlayerB,"esssssssss",:PBTrainers],
     "PlayerC"=>[MetadataPlayerC,"esssssssss",:PBTrainers],
     "PlayerD"=>[MetadataPlayerD,"esssssssss",:PBTrainers],
     "PlayerE"=>[MetadataPlayerE,"esssssssss",:PBTrainers],
     "PlayerF"=>[MetadataPlayerF,"esssssssss",:PBTrainers],
     "PlayerG"=>[MetadataPlayerG,"esssssssss",:PBTrainers],
     "PlayerH"=>[MetadataPlayerH,"esssssssss",:PBTrainers]
  }

And that's all the coding part. Three other things you will need to do.
1. Add Lava Surf as a move to moves.txt

Spoiler:

560,LAVASURF,Lava Surf,075,95,FIRE,Special,100,15,0,08,0,bef,"It swamps the area around the user with a giant wave of molten rock. It can also be used for crossing lava."

2. Add a filepath for each character in your metadata.txt (red part is the addition)
I'm just using the default surfing graphic, you can use a special graphic or whatever

Spoiler:

PlayerA=POKEMONTRAINER_Red,trchar000,boy_bike,boy_surf_offset,boy_run,boy_dive_offset,boy_fish_offset,boy_fishsurf_offset[COLOR="red"],boy_surf_offset[/COLOR][COLOR="red"],boy_fishsurf_offset[/COLOR]
PlayerB=POKEMONTRAINER_Leaf,trchar001,girl_bike,girl_surf_offset,girl_run,girl_dive_offset,girl_fish_offset,girl_fishsurf_offset[COLOR="red"],girl_surf_offset,girl_fishsurf_offset[/COLOR]

3. Just like with bridges, you'll have to add the terrain tag to lava tiles through the Editor. Otherwise they won't be seen as lava tags. Don't forget that the terrain tag has to be added to the tile individually on each tileset.

4. (Optional) Make Lava Surf a tm/hm move. I didn't provide this, but you can just basically copy surf and rename it.

I've provided a 4th gen style lava autotile you can use (credit to rayquaza_dot)

Note that while this allows for the graphics to change and work for fishing, this does not enable fishing while lava surfing, because I think that's just silly.
Tutorial is written for v15, untested for previous versions.

hey mej71 plz plz make lava surf for pokemon essentials 18.1

He is offline. Probably try to adapt it with how surf works.
