How to disable a HIT area in AS2?

Question

How to disable a HIT area (a movieClip with instance name "HIT") in AS2?

Please note that I don't want to hide the hit area after it get hitted. Just needed a code that disable it or remove its instance name so that other objects cannot hit it again.

Answer 1

You can just do :

your_mc.hitArea = null

Or

your_mc.hitArea = undefined

Answer 2

If you want an instance c1 to be disabled after being touched, you can do:

c1.onEnterFrame = function():Void {
    if (this.hitTest(anotherMovieClip)) {
        delete this.onEnterFrame;
    }
}

The hitTest can't occur after the onEnterFrame function is deleted.
