It seems I solved this problem. I've used hgrunt-compatible model from cz deleted scenes and probably there was some lacks in compatibility. With default model he attacks quick enough.
Hello, can you help me with some issues on my map.
There is hallway with doors on sides. When player approaches one of door opens and hgrunt jumps from room and engages with player.
But the problem is grunt that is waiting about 3 sec after action animation so he can be beaten with crowbar without any opposition. Can I give him behavior more like grunt_repel.
