In pyglet sprites are basically just a convenience wrapper around a quad of vertices stored in a vertex list. Unlike some other game libs (pygame comes to mind), sprites are not typically drawn individually, instead they are just used as an abstraction to manipulate the vertex list inside a Batch object. The batch object itself is what is drawn.
Pyglet Group objects are not groups of sprites objects (I think the name is unfortunate), they are an abstraction for an OpenGL state and can also be used to specify the draw order. One or more vertex lists can belong to a group and groups can be nested. Sprite groups allow sprites with common state (texture, blending , etc) to be drawn with maximum efficiency since OpenGL state changes are fairly expensive. Pyglet does not have a built-in way to nest sprites in the manner you describe. This functionality would need to be built by you, or you could use a scene management library like cocos2d. -Casey On Fri, Feb 12, 2010 at 2:24 AM, Philippe <[email protected]> wrote: > Hi, > > still new to pyglet.
