Im also stuck at this one... At first i wanted my maincharacter to walk up to a hostage ,sitting backbound on the ground, kneel then get back up and point his gun and fire. I managed to get everything to work but when i reached and not managed to finish the step where i need the hostage to also play animations in the exact time the maincharacter does i moved over to this idea.. just to be as stuck as before..
If i dont manage to solve how to play animations in sync i will continue on this one and i´ll post the solution here right away!
