I was making a game and using one of the pixel shader effects and I didnt see this event but if there is one please correct me. I wanted to check if an effect was active during runtime I didnt see an option that said something like "Is Object's TintPlus Activated?". Instead im using a variable to check that but just saying that it would be a bit more convienient XD
AFAIR applying effects isn't possible in runtime. I'm afraid we should be careful not to put too much conditions/expressions, because even now Sprite's condition list is large. If something can be handled with single PV - why not work this way?
