character controller collision

hi at all. ;) i red unity documentation about CharacterController class and i seen that for manage collision in character controller there is only a function : OnControllerColliderHit;

problem of this function is that is called only while charactercontroller is performing a Move.

if my character controller represent a enemy that is stopped at a point and i shoot him,him doesn't catch a collision because in this moment enemy character controller doesn't performing a move.

so how to respond at collision if a character controller is stopped?

thanks a lot ;)
