Using baked rotations is a great way to improve graphical performance when dealing with rotating sprites. Load your the graphic for your
FlxSprite by using
FlxSprite.loadRotatedGraphic(), and the system will generate a sprite sheet for your sprite that has frames for all of the possible angles. When you set the angle of a
FlxSprite which is using baked rotations, it will choose the frame(s) that are closest to your specified angle.
// sprite's graphic will be baked using 16 rotations. sprite.loadRotatedGraphic('path/to/image.png', 16);
