Variable scope type problem thing ...

[Nitchy]

Arrrr, this stupid thing is driving me insane. I have a movie called mainBg with this code:

onClipEvent (load) {
	var bgRand;
	bgSpeed = 30;

	function attachBg() {
		bgRand = random(4);
		if (bgRand == 0) {
			bgRand = 1;
		}
		
		this.attachMovie("bgTile" + bgRand, "tile" + bgRand, 1);
	}
	
	attachBg();
	bgStartX = this._x;
}

onClipEvent (enterFrame) {	
	this._x -= bgSpeed;
	if (this._x <= (bgStartX - this["tile" + bgRand]._width)){
		this.removeMovieClip("tile" + bgRand)
		attachBg();
		this._x = bgStartX - bgSpeed;
	}
}

Then I have another movie clip called tileBg. In this mc all I'm trying to do is

onClipEvent (load) {
    trace(_root.mainBg.bgRand);
}

All it traces is undefined! Any ideas, please?!

The problem is that you are limiting the scope of the variable by defining it with var. bgRand only exists while the load event is occuring, and is deleted immediately thereafter. Remove the line:

var bgRand;

and it should work fine.

Sorry, that's still not working ... don't I need to delcare it anyway so that the statements in the enterFrame event can use bgRand (as it was defined in the function)?

What I have now:

MainBg

onClipEvent (load) {
	bgSpeed = 30;

	function attachBg() {
		bgRand = random(4);
		if (bgRand == 0) {
			bgRand = 1;
		}
		
		this.attachMovie("bgTile" + bgRand, "tile" + bgRand, 1);
	}
	
	attachBg();
	bgStartX = this._x;
}

onClipEvent (enterFrame) {	
	this._x -= bgSpeed;
	if (this._x <= (bgStartX - this["tile" + bgRand]._width)){
		this.removeMovieClip("tile" + bgRand)
		attachBg();
		this._x = bgStartX - bgSpeed;
	}
}

tileBg

onClipEvent (load) {
	trace("load: " + _root.mainBg.bgRand);
}

onClipEvent (enterFrame) {
	trace("enterFrame: " + _root.mainBg.bgRand);
}

Please help! This is driving me insane ...

Are you instantiating both MCs in the same frame? Try instantiating tileBg one frame after mainBg.

Worth a try.

Nope, no luck ... could it be something to do with the use of attachMovie or smth? Or the that the bgRand function is in the load event?
