Is There Is A Way To Make Interactive Animation [Ragdoll based]
Like if he crashed in something he falls ?

Ragdolls are supported, you can check the "game basics/character ragdoll" tutorial
you can also simulate shot hits on the skeleton
apply custom pre-generated animations
apply modifications to the skeleton via modifying skeleton bone orientations in the code

It's all in the tutorials

sorry other question do you have Neural-Network AI Based?
or i will have to do my own?

AI needs to be programmed manually
