Question

I am trying to get the bitmapdata from a MovieClip and create a Sprite with it, because I want to use this Sprite as a mask for the MovieClip, but I don;t know how. I have looked around on how I could do this, but I didn’t find anything. Can someone help me?

EDIT: Also, how will I be able to edit its contents afterwards? For example, how would I change its color?

Answer 1

To draw a MovieClip onto a BitmapData object:

var bitmapData:BitmapData = new BitmapData(mc.width, mc.height);
bitmapData.draw(mc);

Then there are a few functions to manipulate the bitmap data (e.g. colorTransform()).

To draw the bitmap data onto a Sprite instance, see Sprite.graphics.beginBitmapFill()

var sprite:Sprite = new Sprite();
var g:Graphics = sprite.graphics;

g.beginBitmapFill(bitmapData, null, false);
g.drawRect(0, 0, bitmapData.width, bitmapData.height);
g.endFill();
