so, I am making a zombie shooter game and figured the best way to give the zombies a sense of health would be to make multiple animations and every time it is hit by a bullet the animation would increase to the next one and on the last animation it would destroy itself. but I can't figure out how to increase the animation by 1 each time only hard set it to one, meaning I would have to make a, if animation is this when hit then change to this one, sort of system but I want an easy thing to do this could anyone help me set it up, so it is optimized? I will continue trying and will tell you if I manage to find it out by myself, but until then please help me figure this out.
