you have to add the power trigger in the changestate you have been coding in this topic as well.

change the trigger to animelemtime(=0

you are using animtime wrong. i personally despise that trigger.

You can make it like these

statedef xxxx

projectil

changestate  to state 0 (stand position)

and then make another changestate using as a trigger1= command = "a" && animelem >= 8
change to the same state or to another that is similar to these

what you ar making is that when you are on the state if you dont press a you will go to state o and if you press it  and the animelem is >= 8 you will change to the fireball state... you can use 2 statedef for the fierball to avoid cheapness

you can add a changestate on the statedef that the trigger1 = command = "a" ... it would work better if you use && another condition like the animelem = anim before the char launches the fireball

You have a fireball state. It's activated by QCFx2 a, you want every fireball AFTER this to be usable by pressing a correct? If there's no special startup animation or whatever to the state you can use a simple changestate in the cmd to reactivate the move each time you press a provided you're already in said state

trigger1 = stateno = fireball state && time > previous fireball should have fired by now

Yeah, when you use AngleDraw the flag A in the air file stops having effect.
You'll need a Trans sctrl in that same helper state.

[state 0, Trans]
type = Trans
trigger1 = 1
trans = addalpha
alpha = 256, 256

He just means you should make your animation have many frames, your lava ball one. and change the CLSn boxes on the frames according to the time the animation shrinks in game.
So that the boxes shrink becuase of the animation, as there is no other way to do it.
