[Scripting Question] Adding Terrain-Changing Abilities

kwaiipotato said:

the terrains themselves are coded in 17x and I believe you can port them to 16x without issues. though the surge abilities i'll try and code below.
it's divided between the messages that pop up in Pokebattle_Battle and the actual effects spread around Pokebattle_Move, Pokebattle_MoveEffects and Pokebattle_BattlerEffects. you can use the search thingy in the script editor.

if you want to code them yourself:

you have to use a field effect instead of a weather (those are in PBEffects, close to things like trick room, magic room and gravity):

first you define the effect there. in the part that says "these affect both sides" add the line:
MISTYTERRAIN = (any number not used in that bunch of effects)

then an ability that applies it ("coded" it on the fly based on intimidate, tell me if it works cause i'll use it too XD):
paste this in PokeBattle_Battler, below the code for intimidate:

if self.hasWorkingAbility(:MISTYSURGE) && onactive
PBDebug.log("[#{pbThis}: has Misty Surge]")
@battle.pbDisplayEffect(self)
@field.effects[PBEffects::MistyTerrain]=5
end

also a move effect in MoveEffects that applies it (this one was in 17x):

class PokeBattle_Move_XXX < PokeBattle_Move #replace XXX with an unused effect number
def pbEffect(attacker,opponent,hitnum=0,alltargets=nil,showanimation=true)
if @battle.field.effects[PBEffects::MistyTerrain]>0 #this makes the move fail if Misty Terrain is already on
@battle.pbDisplay(_INTL("But it failed!"))
return -1
end
pbShowAnimation(@id,attacker,nil,hitnum,alltargets,showanimation)
@battle.field.effects[PBEffects::TerrainY]=0 #this makes the move eliminate other similar terrain effects
@battle.field.effects[PBEffects::TerrainZ]=0
@battle.field.effects[PBEffects::MistyTerrain]=5 #this makes the move set Misty Terrain to last 5 turns
@battle.pbDisplay(_INTL("Misty Terrain was applied!"))
return 0
end
end

and then go into Pokebattle_Move/Battle/etc and add conditions like:
if @battle.field.effects[PBEffects::MistyTerrain]>0
to any move/effect/ability that interacts with the terrain.

I need to sleep lol
