AS3 - How to copy sprites / graphics of sprites?

Solution

You can use the function `copyFrom`.

Something like this:

var s:Sprite = new Sprite();
s.graphics.beginFill(0);
s.graphics.drawRect(0, 0, 100, 100);
s.graphics.endFill();
addChild(s);

var s2:Sprite = new Sprite();
// Copyfrom accepts a `Graphics` object.
s2.graphics.copyFrom(s.graphics);
s2.x = 100;
s2.y = 100;
addChild(s2);

Have a look at the documentation about copyFrom().

Problem

Let's say I have a 2D level that is build out of 2D blocks. Some of them are boxes. The boxes look just the same. No difference! How can I "copy" or clone the graphics of one box to another ? The only difference the boxes will have is that `sprite.x` and `sprite.y` have different values. I would probably go that way: ``` public static function drawBox(graphics:Graphics):void { graphics.clear(); // draw box } drawBox(box1.graphics); drawBox(box2.graphics); drawBox(box3.graphics); ``` No textures will be used, only vector drawing! Is this a good practice ? Is there another way to achieve the same ? Update: Sometimes I draw sprites randomly (very hard to redraw them if I need many instances of one sprite and all its attributes).
