Using Private Variables To Avoid Garbage Collections

Garbage collection is occasionally recycling my tween variables and thereby killing my tween.

I was wondering if it would be possible to use a private array of variables that I reset after the tweens are completed, since I believe garbage collection does not apply to private variables (please correct me if I am wrong so far).  However, i seem to be having trouble with the private variables.

here is my code on this.  really the slideBlade function is the only revelant part, but I thought I would also include the part where it is called, since it runs four times in a row.  (bladeTotal is always equal to 4)
public function slideBlade(which, pos, bladeTotal) {

			

			trace(bladeTotal+": bladeTotal");

			

			

			var tween:Tween = new Tween( which, "x", Regular.easeInOut, which.x, which[pos], .6, true);

			

		}

		//--------------------------------------------------------------------------------

		public function bladeEngine(which) {

			removeThumb(null);
 

			if (this.currentBlade == which) {

				for (x = 1; x <= bladeTotal; x++) {

					whichBlade = this["blade" + x];

					slideBlade(whichBlade,"closePos",bladeTotal);

				}

				which.blade.gotoAndStop(1);
 

				this.currentBlade = null;

				this.bladeNumber = 0;

			} else {

				if ( this.currentBlade != null) {

					this.currentBlade.blade.gotoAndStop(1);

				}

				if (which.bladeNum < this.bladeNumber) {

					for (x = which.bladeNum + 1; x <= bladeTotal; x++) {

						whichBlade = this["blade" + x];

						slideBlade(whichBlade,"closePos",bladeTotal);

					}

				} else {

					for (x = 1; x <= bladeTotal; x++) {

						if (x <= which.bladeNum) {

							whichBlade = this["blade" + x];

							slideBlade(whichBlade,"openPos",bladeTotal);

						}

					}

				}

				this.currentBlade = which;

				this.bladeNumber = this.currentBlade.bladeNum;

				this.currentBlade.blade.gotoAndStop(2);
 

				if (this.currentBlade == which) {

					buildTree( this.bladeNumber, this.currentBlade.bladeName, "", "" );

				}

			}

		}

Yeah, just create a private var outside your function block, e.g.

private var tween:Tween;

then in your function:

tween = new Tween(...);

That should stop your tweens from being killed.

Is that not working for you?

Put them all in an array / object container. Pop/shift them as you complete them or just dump the container when they're all done.

MattKenefick-
I'm sorry, I'm not sure how that would work?  Do you kill them after they run?  Can you show me how that would work?
