cocos.batch module¶
Batch
Batches¶
Batches allow you to optimize the number of gl calls using pyglets batch
-
class
BatchNode
¶ Bases:
cocos.cocosnode.CocosNode
-
add
(child, z=0, name=None)¶ Adds a child and if it becomes part of the active scene, it calls its
on_enter()
method.- Parameters
child (CocosNode) – object to be added
z (Optional[float]) – the child z index. Defaults to 0.
name (Optional[str]) – Name of the child. Defaults to
None
- Returns
CocosNode – self
-
draw
()¶ This is the function you will have to override if you want your subclassed
CocosNode
to draw something on screen.You must respect the position, scale, rotation and anchor attributes. If you want OpenGL to do the scaling for you, you can:
def draw(self): glPushMatrix() self.transform() # ... draw .. glPopMatrix()
-
remove
(child)¶ Removes a child given its name or object
If the node was added with name, it is better to remove by name, else the name will be unavailable for further adds (and will raise an Exception if add with this same name is attempted)
If the node was part of the active scene, its
on_exit()
method will be called.- Parameters
obj (str or object) – Name of the reference to be removed or object to be removed.
-
