Third person assassin

If your guard is built in another application such as Cinema 4D or other 3D modelling softwares then you create an animation in there of your guard. I would make about 3 animations on your guard, one of him idle (not doing anything, maybe fidgeting, or breathing). Another on him walking, and another in an attack position ... Make sure these animations are ALL ON THE SAME TIME LINE and import the whole file into Unity.

When you have done that, click on your object you just imported, then in the Inspector add your animations according to name and frame range.

Then you add code to activate particular animations eg:

function Update() { if (GuardAttack == true) { animation.wrapMode = WrapMode.Clamp; animation.Play("GuardAttack", PlayMode.StopAll); } else animation.wrapMode = WrapMode.Clamp; animation.Play("GuardIdle", PlayMode.StopAll);
