I’m using a number of onEnterFrame functions in my project and to slow down the CPU consumption I want to delete them when they’ve done their job. I’ve got this code to work with things like alpha fades, but the delete this.onEnterFrame doesn’t work with the easeing code. I think it’s the division part of the code that’s affecting it. Can someone lend me a hand?  
Thanks,  
GD

```auto
var targetY = 220;
this.onEnterFrame = function() {
	if (blank_mc._y<targetY) {
		blank_mc._y += (targetY-blank_mc._y)/10;
		trace("ease");
		if (blank_mc._y>targetY) {
			delete this.onEnterFrame;
		}
	}
};

```

Lets make some output here:

blank\_mc.\_y += (targetY-blank\_mc.\_y)/10;

```auto
(220 - 0) / 10 = 22
(220 - 22) / 10 = 19.8
...
...
(220 - 219) / 10 = 0.1
(220 - 219.1) / 10 = 0.09
(220 - 219.19) / 10 = 0.81

```

See? Never gona be higher then the targetY. If you want 10 steps to get to final destination, so, keep the first value in a variable.

Balala ment that the blank\_mc.\_y will never reach the targetY so it keeps looping.

try  
[AS]  
var targetY = 220;  
this.onEnterFrame = function() {  
if (Math.abs(blank\_mc.\_y-targetY)\>1) {  
blank\_mc.\_y += (targetY-blank\_mc.\_y)/10;  
trace(“ease”);  
}else {  
delete this.onEnterFrame;  
}  
};  
[/AS]
