I want to modify bullet script to check have faced object "Take_Damage" function or it doent, and only if it have, then call it.
But i dont know how to check it.

Use Object's has_method(method: String) to check whether the object has a method defined:

if body.has_method("take_damage"):
    body.take_damage()

This is also called "duck typing".
