[Error] Error during a battle

[AskipLudo]

Hello, It's been a long time not messing with Pokemon essentials and I don't know who I got an error while doing a battle, I've made like 5 before this one,

This is the error:

[2023-09-16 03:07:26 +0200]
[Pokémon Essentials version 21.1]
[v21.1 Hotfixes 1.0.1]

Exception: NoMethodError
Message: undefined method `has_active_ability?' for #<Battle::Battler>

Backtrace:
[Generation 9 Pack] [004] AI_MoveEffects.rb:842:in `block in <main>'
Event_Handlers:139:in `trigger'
Battle_AI:98:in `move_will_fail?'
AI_ChooseMove:190:in `pbPredictMoveFailure'

Battle_Battler:461:in `each_with_index'
Battle_Battler:461:in `eachMoveWithIndex'
AI_ChooseMove:25:in `pbGetMoveScores'

And about what I'm doing i'm just making the player into an AI so that both fight themselves. Found the code somewhere on the forum and added it to my essentials and worked perfectly until a fight against 2 trainers
One with a Paras and one with a Poliwhirl.

Thanks for any help (and maybe any way to improve the AI vs AI thing well be nice)

Edit: After some checking seems like it's pointing to this code:

#===============================================================================
# Rest
#===============================================================================
# Adds failure check with the Purifying Salt ability.
Battle::AI::Handlers::MoveFailureCheck.add("HealUserFullyAndFallAsleep",
proc { |move, user, ai, battle|
next true if user.battler.has_active_ability?(:PURIFYINGSALT)
next true if !user.battler.canHeal?
next true if user.battler.asleep?
next true if !user.battler.pbCanSleep?(user.battler, false, move.move, true)
next false
}
)

Because the Poliwhirl actually have the Rest move

Hello, @Ludow79,
I believe this error may be due to the new script imported (Gen 9 Pack) being based on a later version of essentials than your other scripts
If this is the problem, then this can be fixed by putting:

class Battle::Battler
  alias has_active_ability? hasActiveAbility?
end

However, you should expect to find other errors further on for the same reason
Hope this helps!

Weird then because I use Essentials v21.1 with the hotfixes

Ok, thanks for telling me that.
Upon reflection, that is not the issue.
The issue is that the battler referred to in line 842 is a Battle::Battler, when it should be a Battle::AI::AIBattler
(Apologies, I am not very familiar with the new AI system)

Weird I feel like I'm the only one with this error tho, and I don't know where I should modify this since I'm also not familiar with all this. Maybe I will wait and see if the creator of this will check my message on reliccastle xD

 

[Swdfm]

You can ask him by all means, but he will likely say that the addition fo the Gen 9 Pack caused the issue. I will come back and have another look at this tomorrow

Well I didn't tested much those days but the last time I test with a pokemon with rest and the "has_active_ability?" changed to "hasActiveAbility?" in line 842 didn't made any error, I guess everything didnt get changed

Edit: The dev will fix this next update so it will be fixed :P
