Another approach is to patch cocos an Ninteroc mentions in this thread:
http://thread.gmane.org/gmane.comp.python.cocos2d.user/1686
If this works for you, and performance compares well with your two-batchs
workaround, then cocos should incorporate that patch.
My tests show no difference in performance between the patch and my work
around.
I have another question. I have one layer which uses this method:
def on_mouse_drag(self, x, y, dx, dy, buttons, modifiers):
if Mouse.buttons_string(buttons) == 'MIDDLE':
self.x += dx
self.y += dy
My program idle fps is 500 (on ubuntu, so it's half of what I see on win7).
So if I do something like 'press MIDDLE and move mouse a lot', I see a
FPS of about 250. This is expected.
However if I add one more layer to the scene and do the same movement, I
see FPS drop to 50, it does not matter if the new layer is event handler
or not.
What can be the reason for this drop?
