[Scripting Question] Apply Yawn effect on every pokemon on the field ?

[hirokimura]

Hello guys !
I'm planning to do something in my game.
Kinda like a field effect that apply Yawn effect to both pokemons. It would be that as long as the terrain is ON, at the end of each turn, it applies Yawn to every pokemon battling.
Thing is, I don't even know where to start.
I don't need it cooked, but, can someone help me to see what I should do first ?
Thank you !

Look up where the terrain field effects are applied (Ctrl+Shift+F is your friend) and look into how Yawn is implemented. Certain Pokémon will be immune to this effect of course.

Thanks for the answer !
I progressed a bit : I can now have my Bells field functions well and I can start it with a move.
I tweaked a bit with grassy's healing at the end of the round, but seems I cant get it working : here is my code

def pbBellsYawn(battler)
    return if battler.fainted?
    # Bells putting Yawn
    if @field.terrain == :Bells && battler.pbCanSleep? && battler.effects[PBEffects::Yawn] > 0
      PBDebug.log("[Lingering effect] Bells made #{battler.pbThis(true)} drowsy!")
      battler.effects[PBEffects::Yawn] = 2
      pbDisplay(_INTL("The bells made {2} drowsy!", battler.pbThis))
    end
  end

Idk what I'm doing wrong, but I feel I'm closer to the goal.

It looks like your code is defined in the Battle class. How is pbBellsYawn being called? I did notice that battler.effects[PBEffects::Yawn] > 0 only returns true if the battler is already under the effect of Yawn. By changing > to >= allows Pokémon who are not under the effect of Yawn to gain the effect.

Thanks for the help !
Indeed, I defined the process but I didn't call it, so it didn't work haha !
After calling it, I got few errors, and fixed them with your advices and others, here is the final code just for the record

#----------------------------------------------------------------
    # End Of Round Yawn from Bells Terrain
  #=============================================================================
def pbBellsYawn(battler)
    return if battler.fainted?
    # Bells putting Yawn
    if @field.terrain == :Bells && battler.pbCanSleepYawn? && battler.effects[PBEffects::Yawn] == 0
      PBDebug.log("[Lingering effect] Bells made #{battler.pbThis(true)} drowsy!")
      battler.effects[PBEffects::Yawn] = 2
      pbDisplay(_INTL("The bells made {1} drowsy!", battler.pbThis))
    end
  end

Thank you very much for the help ! It's very appreciated !
