Hello guys

I’m trying to get an AS that allows me to ease the alpha of the MC from 0 to 100…I have been trying but I get an endless loop and the MC disappears after a while.

Anyway, this is what I’m trying to do…if you guys got better Ideas please post it here…thanks a lot:

MovieClip.prototype.alphaUp = function(alpha){  
this.onEnterFrame = function(){  
this.\_alpha +=alpha/10;  
if(this.\_alpha\>alpha){  
delete this.onEnterFrame;  
}  
};  
};

this works…makes the alpha goes up but it wont stop and makes the MC disappears after a while…I want the function to stop adding more alpha…

Thanks again
