[Scripting Question] Having trouble adding a new move to essentials

So I'm trying to add a new move called Dragon Fleet into my game. I wanted it to work like Beat Up, dealing slightly more damage, but only add hits for the user and all Dragon-types in the user's party. In the PokeBattle_MoveEffects script, I copied the code for Beat Up and tried to change it so it would only register for Dragon-types, but it didn't work differently than Beat Up.
---------------------------------------------------------------------------
Here is the code that I changed from Beat Up in order to implement Dragon Fleet:
class PokeBattle_Move_179 < PokeBattle_Move
def pbIsMultiHit
return true
end

def pbNumHits(attacker)
return @participants.length
end

def pbOnStartUse(attacker)
[email protected](attacker.index)
@participants=[]
for i in 0...party.length
if attacker.pokemonIndex==i
@participants.push(i)
elsif party && !party.egg? && party.hp>0 && party.status==0 && party.pbHasType?(:DRAGON)
@participants.push(i)
end
end
if @participants.length==0
@battle.pbDisplay(_INTL("But it failed!"))
return false
end
return true
end

def pbBaseDamage(basedmg,attacker,opponent)
[email protected](attacker.index)
atk=party[@participants[0]].baseStats[1]
@participants[0]=nil; @participants.compact!
return 5+(atk/7)
end
end

Here is the original code for Beat Up:

class PokeBattle_Move_0C1 < PokeBattle_Move
def pbIsMultiHit
return true
end

def pbNumHits(attacker)
return @participants.length
end

def pbOnStartUse(attacker)
[email protected](attacker.index)
@participants=[]
for i in 0...party.length
if attacker.pokemonIndex==i
@participants.push(i)
elsif party && !party.egg? && party.hp>0 && party.status==0
@participants.push(i)
end
end
if @participants.length==0
@battle.pbDisplay(_INTL("But it failed!"))
return false
end
return true
end

def pbBaseDamage(basedmg,attacker,opponent)
[email protected](attacker.index)
atk=party[@participants[0]].baseStats[1]
@participants[0]=nil; @participants.compact!
return 5+(atk/10)
end
end
---------------------------------------------------------------------------
I know that the method for ".hasType?" was called because there was no error, it just always returned true. When I tried to see what would happen if I put an "!" in front of it to negate the statement, the attack only hit once (based on just the user). Accessing a type works if it is the user or the opponent, but it doesn't seem to work properly here. Thanks if anyone is able to help me.

In your code example, you used .pbHasType? Try charging it to just .hasType? I'm pretty sure the method you're calling is the ove that checks if the player has a pokémon of that type on the team. And, based on your scenario that would always return true.

(Note: there is a method "pbHasType?" Which checks an individual pokémon's type, but it is defined in the PokeBattle_Battler class, so it doesn't really work on the party - only on pokémon in battle).

That worked. Thank you so much!
