Well, if you had something like


onClipEvent(enterFrame){
  if(this.HitTest("wall"){
    this._visible=false;
  }
}

Then you could do something like this I suppose.


onClipEvent(enterFrame){
  if(this.HitTest("wall"){
    _root.attachMovie("explosionClip","explosion",this._depth);
    _root.explosion._y=this._y;
    _root.explosion._x=this._x;
    this._visible=false;
  }
}

Will that for you?

thanks a ton for the help, its working fine. I have have 1 more question, is there a way i can combine hitTests? something like…

if (this.hitTest(_root.block, _root.block1, _root.block2)) and so forth?

for that, you could use the logical operators.

[AS]

//logical OR: ||

if(1>2 || 2>1){
//do stuff…
}
//gets executed because the second condition is true

//logical AND: &&
if(1>2 && 2>1){
//do stuff…
}
//does not get executed because only one of the conditions is true.
[/AS]

Thnx njs, thats working quite well for me. I know i said that was my last question but i have one more. Is there a way to void an action, like after it has been executed once, it can not be used again?

  1. You could delete the event handler:
    [AS]myMovieClip.onEnterFrame = function() {
    // statement(s)
    if (this.hitTest(this._parent.myOtherClip)) {
    // statement(s)
    delete this.onEnterFrame;
    }
    };[/AS]
    This method only works for dynamic event handlers.

  2. Use a variable:
    [AS]onClipEvent (enterFrame) {
    // statement(s)
    if (!myVar && this.hitTest(this._parent.myOtherClip)) {
    // statement(s)
    myVar = true;
    }
    }[/AS]
