Thanks, that worked. Just have to figure out how to restrict it to certain skins now.
You would need to use an If Compare statement.
Something like:If Compare: LA-Basic[54] = 1*
Offensive Collision (specific to that costume)
Else
Offensive Collision (normal)
End If
*The number "1" being whichever costume slot you want the different collision on.
If you have Project: M 3.0 or later, you can look at Mario's forward smash in PSA to get an idea of how costume-specific hitboxes work.
