[quote:3pv36got]Maybe a simple bullet with gravity?
After a bit of tinkering I managed to get a pretty good effect using bullet. When a worm is touched the hawk dives towards that position and destroys the worm. The hawk bounces off the worm and I angled the worms collisions so the hawk will always bounce upwardly. I am going to use animations to give the arc effect as the trajectory is is pretty straight. It's not that bad though.
For anyone wanting to do similar here is the code. The bullet gravity is 0 which is default I believe.
