Images, each at their own position, onto a new image:Ĭlass MyGame extends Game įlareAnimations are normally used inside FlareComponents, that way FlameGame will handle calling Working with the SpriteBatch API to optimize your drawing calls.įor such usecases Flame comes with the ImageComposition class. In some cases you may want to merge multiple images into a single image this is calledĬompositing. You render it with a Canvas and an optional Paint, BlendMode and CullRect.Ī SpriteBatchComponent is also available for your convenience.
