Adding Move Animations?

[KaktusArt]

I'm getting into editing the decomp for some qol/update changes, and I wanted to make some extra moves too
I made the power, pp, description, etc. Everything transfers perfectly to the game.

...but I can't for the life of me find a way to give it an animation in battle.

And I don't mean add an animation. Just frankenstein-ing existing moves.
But not even copy-pasting already existing animations worked.

Is there something I'm missing? What is the "formula" for a move animation? What files do I have to edit?

The only file you have to edit is data/battle_anim_scripts.s.
You just add an entry for your new move to gBattleAnims_Moves before Move_COUNT, making sure that the order of the table matches the same order in which your moves are defined at include/constants/moves.h, then write an animation script somewhere below gBattleAnims_Special following the lead of any animation script in the file, and that's basically it.

YESS! That finally worked! ^v^
I had put my moves on top for ease of access lol. Had no idea the order mattered when I was already calling the move anyways...

Thank you so much!

Also, in some animations, ie Wrap, there are 5 numbers. What do these mean?

createvisualtask AnimTask_ScaleMonAndRestore, 5, 10, -5, 5, ANIM_TARGET, 0

They're parameters read by the AnimTask_ScaleMonAndRestore function that createvisualtask is executing.
