Have you checked what I mentioned above? When I said I would need to see the rest of your code to be sure I didn't mean I want to (frankly I don't have time) but that I'm not 100% sure. Still it strikes me as a pretty likely reason for your problem: instead of calling Animate just once to start playing the animation, you call it every frame raptorhealth=0 (which is every frame until it is hit again) thus resetting the animation every frame.
