Here is a perfectai script I modifed so that a pawn was made unconcious for a few seconds if he was clubbed with a cosh and respawns when he comes round. If he is struck with any other weapon he is killed. If you look through it you will see how I did the respawn. This script works ok for me no problems. Hope this helps you.
