How do I assign sprite to another sprite

Hi,

can anybody tell me, how do I assign any sprite to another? I have lot of object and i set some actions of one sprite depend on another sprite. For example, man and gun and lot of theese objects, and i need to assign gun to man, and affect man defend on his gun, not others...

Can anybody help me? I really do not know how to continue...

You'd probably want to use the pin behaviour, and have the gun assigned to an image point that you place at a hand.
