How would I make a type of shield that only works when you hold on to the key, and when you let go it stops? This is my code so far.

    Shield()
        if(!(usr.shield))
            if(usr.canshield)
                usr.shield = 1
                usr.frozen = 1
                usr.can_attack = 1
                usr.clash = 1
                usr.overlays += 'Shield.dmi'
                sleep(75)
                if(usr.shield)
                    usr << "Battle Information: Your shield has broken!"
                    usr.overlays -= 'Shield.dmi'
                    usr.frozen = 0
                    usr.can_attack = 0
                    usr.clash = 0
                    usr.shield = 0
                    usr.canshield = 0
                    sleep(30)
                    usr.canshield = 1
                    return
                    
        else
            usr.overlays -= 'Shield.dmi'
            usr.frozen = 0
            usr.can_attack = 0
            usr.clash = 0
            usr.shield = 0
            return

Here's an idea to help you along the way:

Define a macro, one calling a verb when the key is pressed down (not held) and another, same macro key, calling another verb (or the same verb with a different argument) when the key is released.

Only problem with this is quickly pressing the shield button twice. Then it stays shielded without holding down the button.
