[Scripting Question] Defense curl in the ability?

Hi everyone!
I'm new to Essentials and i am still trying to learn some basics.
I am trying to write an ability that does:
-increase defense by one upon entering into battle.
-set the [PBEffects::DefenseCurl] to true

In practice: the pokemon casts defense curl upon switching in. (useful for pokémon with rollout or ice ball like Spheal evolution line).
The code is the following:

# Iron Curl
if self.hasWorkingAbility(:IRONCURL) && onactive
self.effects[PBEffects::DefenseCurl]=true
if pbIncreaseStatWithCause(PBStats::DEFENSE,1,self,PBAbilities.getName(ability))
PBDebug.log("[Ability triggered] #{pbThis}'s Iron curl raises Defense")
end
end

The increase of defense works fine (at least the animation works, i am not sure if the defense really grows). BUT the defense curl doesn't seem to work!
I really don't know why.. Anyone got an idea?

what do you mean by the increase in defense works but defense curl doesnt?

There's a mechanic where if you use defense curl and then Rollout or Ice ball, the damage is doubled. It was implemented with the second/third generation.
The [PBEffects::DefenseCurl] doesn't work properly with this ability because the damage of rollout (or ice ball) doesn't double when I test it.

ok so my knowledge on moves is a little lacking but
under PokeBattle_MoveEffects
find shift+=1 if attacker.effects[PBEffects::DefenseCurl]
and change to
shift+=1 if attacker.effects[PBEffects::DefenseCurl] || attacker.effects[PBEffects::IronCurl]

no clue if it'll work but worth a try

You gave me the perfect hint! It was kinda what you said but using attacker.hasWorkingAbility(:IRONCURL) instead. Thanks a lot!
If someone is interested, here it is the code.
Insert this in pokebattle_battler (near intimidate or download)
and add the Bold thing in pokebattle_moveeffects:
(if you have pokemon elite system, add in EliteBattle_0 the Bold thing)

oh cool glad i could help
