Yeah, it'd help us if you'd let us know if the Rainbow Lazer is a helper or not.

Off the top of my head, if it's all one attack (no helpers, projectiles, etc.), then add trigger1 = power = 0 into the attack's ChangeState...uh, state.

If it's a helper, then still add the above into the actual attack state, but add trigger1 = power = 0 into a DestroySelf state in the helper's stateno.

Note that the trigger numbers should be different from any others you have in the ChangeState and DestroySelf states, otherwise they won't work.
