Flash CS5: ActionScript 2.0: Code to make a Game cursor kill an enemy

Hey, I was trying to make a flash game where a gun cursor hits an enemy…

   I got the cursor to move around the screen with the mouse by using:
              Mouse.hide()
              startDrag(MC_cursor,true)

but I could not find a code or a tutorial online that would show me a code to make the cursor hit my enemy by clicking.

If anyone could help me it’d be great :party::party::party::party::party:
