[RESOLVED] [F8] Is there anyway to "lock" a variable?

[sandyrivers]

I don't know why this is escaping me, but I'm banging my head on this one.

What I want to do is tween a movie clip from point a to point b on the y axis if a button is pressed. I understand the mechanics of coding what I want to do but I don't want to be bothered with plugging in the actual _y starting and ending points. I want to use a variable.

code:

---

var myMCnewY = myMC._y + 103;

mcTween = function() {

     this.onEnterFrame = function() {

          if (myMC._y < myMCnewY){

               myMC._y +=10;

          } else {

               myMC._y = myMCnewY

               delete this.onEnterFrame();

          }

     }

}

buttonMC.onRelease = function () {

     mcTween();

}

---

The obvious problem with this is that since the myMCnewY variable contains myMC._y, it'll always be greater than the clip's current position and the tween will never end. How do I "capture" the ending point in a variable, and then "lock" that number so that it doesn't increase due to the onEnterFrame?

Also, I rather not use the Tween class, as it wasn't working all that well for me and I understand this way.

Thanks in advance for any help!

???

//
mcTween = function (mc, newY) {
	this.onEnterFrame = function() {
		if (mc._y < newY) {
			mc._y += 10;
		} else {
			mc._y = newY;
			delete this.onEnterFrame;
		}
	};
};
//
buttonMC.onRelease = function() {
	mcTween(myMC, myMC._y + 103);
};

you are awesome. thank you.

I can never remember what goes in the parenthesis when writing a function to make it work like I want. I always leave it blank and try to figure out a way around it.

anyways... thanks!
