Buffs given by a certain battle background

[Telemetius]

Hi, I recently implemented a couple new battle backgrounds and one of them is a lava filled cave floor; so I had an idea, why not give to my pokemons a couple buffs depending on the environment, eg.
+1 atk to fire pkms if the battle background is lava -1 atk to water types
+1 def to water pkms if we're underwater +1 atk if we're surfing

So I had a look at the section move effects, secret power where i found this:

when PBEnvironment::Volcano
id=getConst(PBMoves,:INCINERATE)

What I did then was to copy it, replace the second line with:

@battlers[index].pbIncreaseStat(PBStats::DEFENSE,1,@battlers[index],true)

And add it in Pokebattle_battle just after the message: Go! {1}!

What I was trying to do isn't working though.
I tried replacing "when" with "if" and still no luck.

Remember that any "if" comes with an "end".

I'm a little concerned that you're trying to do any coding stuff and you don't know these basics. The above isn't the only mistake you made here; I for one won't help you, because Essentials isn't "My First Coding Device", and if you want to change the coding in Essentials, it is assumed you already know how to use Ruby. There are plenty of guides on the Interweb.

Yes for the moment all my ruby knowledge comes by trials and errors and this one in particulat was just an intrusive thought such as "Hey, why not?". I'm guessing this is too much and too early until I'll get better at it.
