Okay here’s my situation:
I’ve got code which is creating sound objects. The code is inside a method of an object which is then registered to a MovieClip in the library and later instantiated with attachMovie(); This code is totally standard, and looks something like this:
this.theSound = new Sound(this);
this.theSound.attachSound(soundName);
Now my basic problem is hat this code stops working shortly after the app starts and through testing I’ve discovered the precise line of code that is the culprit. Elsewhere in the script therere is another object that contains an array (created in its constructor with the line this.theSounds = new Array();). As soon as any instance of this object actually populates its theSounds array, all future Sound objects created fail (they show up as undefined in the debugger). For those who don’t like to read prose:
theNewObject = function () {
this.theSounds = newArray();
//sound objects will still work
this.theSounds[0] = "puppies";
//all future sound objects will be broken
}
WHAT THE #*&!?
for inquiring minds, here’s the full code:
/********************************

//Constructor is in construct() function

this.endFrame = end;
this._x = start + _level0.theTimeline._x;
this._y = y + _level0.theTimeline._y + 1;
this._height = 29;
this._width = (end-start);
this.theColor = new Color(this);
this.theColor.setRGB(rgb);
this.theSound = new Sound(this);
