AS3 Benchmark: Graphics.beginBitmapFill() vs BitmapData()

Just worked on a racing game…

It requires lots of graphics and bitmaps. I have just discovered the other way how to render bitmaps in the flash.

Before, I’m using BitmapData and insert it in Bitmap, then add it in the stage. Just a while ago, I tried to use the Graphics.beginBitmapFill(). First, I did some benchmark and this how it was:
- using BitmapData:

var bmpData:BitmapData = new BitmapData(100,100, false, 0x000000);
var bmp:BitmapData = new BitmapData(100,100, false, 0x000000);
for(var i:int = 0; i < 10000; i++){
	bmp.draw(bmpData);
}

- using Graphics.beginBitmapFill()

var bmpData:BitmapData = new BitmapData(100,100, false, 0x000000);
var shp:Shape = new Shape();
for(var i:int = 0; i < 10000; i++){
	shp.graphics.beginBitmapFill(bmpData);
	shp.graphics.drawRect(0,0,100,100)
}

This gave me 17ms for Graphics.beginBitmapFill() and 93ms for Bitmapdata()

So I’m suggesting now to use Graphics.beginBitmapFill() for bitmap patterns.
