What is the pyglet "way" to do nested sprites? Sprites that have their
origin/orientation/scale defined by a parent sprite? (a turret on a
tank. orbs circling a wizard. fancy text with letters that can
zoom,spin and fade independently but still line up correctly)
In the pre-pyglet version of my code I did something like this:
Class Sprite:
def old_style_draw(self):
glPushMatrix
glTranslate
glRotate
glScale
self.texture.draw()
for child in self.children:
child.old_style_draw()
glPopMatrix
In the pyglet.sprite world my sprites are out of the draw loop! Pyglet
only loves them for their vertices.
My only idea is to use a ChildGroup:
class ChildGroup(pyglet.graphics.Group):
def __init__(self,parent_sprite):
...
def set_state(self):
glPushMatrix
glTranslate(self.parent_sprite.x....)
...
def unset_state(self):
glPopMatrix
And this idea seems appealing to me except that as far as I can tell
Batches never release any group once its added to them. I use nested
sprites a lot in my special effects. They come and go a lot.
Is there a natural way to do what I want to do with pyglet sprites? Is
there a better way to think about my problem? Should there be a
Batch.remove_group() method?
Thanks for any advice,
Andrew
