Hello,
I've started a file in Flash CS6 that includes animation and actionscript 3 and everything looked fine when I previewed it with CTRL + ENTER during the process. After I saved and closed my .fla I tried the .swf and it is lagging whenever I reach the part that involved most of the complicated actionscript.
I already tried to downsize the preview settings quality and it's still lagging at 20, so I'm not really sure if it's the actionscript itself.
stop();
var lineSize:Number=400;
// doDraw is true when user's mouse is down
var doDraw:Boolean=false;
// resumeDrawing is true when user drags their mouse off stage while drawing
var resumeDrawing:Boolean=false;
/*

Add it to stage & cache as bitmap
*/
var erasableBitmapData:BitmapData = new BitmapData(1280, 768, true, 0xFFFFFFFF);
var erasableBitmap:Bitmap = new Bitmap(erasableBitmapData);
erasableBitmap.cacheAsBitmap = true;
addChild(erasableBitmap);
/*

*/
puddle_mc.cacheAsBitmap = true;
puddle_mc.mask = erasableBitmap;

function mouseFollower (e:Event):void {

}

function mouseClicked (e:Event):void {

mouseclick_mc.visible = true;
}
stage.addEventListener (MouseEvent.MOUSE_UP, mouseRelease)
function mouseRelease (e:Event):void {
mouse_mc.visible = true;
mouseclick_mc.visible = false;
}
I'm leaving the actionscript I used here so it's easier if someone knows how to help me out.
Thank you
