[MDL ED] my monster wont attack, why?

[The chaser]

ah no, I actually learned some maya to do the skeletons hehe!

But everytime my monster is hitting me once it's like.. stops and the enemy stays at one place for some seconds and continously hit the same place even though I'm not close to it.

It's like a script being errored out or something.
Do I need to make all the animations the grunt has into my model to make it work properly?

I think so, just try to make your monster the more similar the grunt, the better.
