Okay, if you want the character to always be ghost, then all you need to do is find this
[Statedef -2]
Implement
[State -2]
Type = Trans
Trigger1 = 1
trans = Add1
[State -2]
Type = NotHitBy
trigger1 = 1
value = AP
Thats it. Now If You want to make it so that the character turns Ghost By Holding Start then You Use This.
[State -2]
Type = Trans
triggerall = Palno >6
Trigger1 = 1
trans = Add1
[State -2]
Type = NotHitBy
triggerall = PalNo >6
trigger1 = 1
value = AP
That Should Work. Hope this helps.
