ANIMATION PROBLEM !! HELP !!
Hi guys. I'm currently making a survival horror game for our thesis and this animation problem is killing me for days. Whenever my enemy attacks, he just stays in place. I want him to follow me when I get too far from him and then attack at close range. Can you help me please?? It's my first time posting at this site. I really need help.
