[Butia-devel-list] The layer problem

[Alan Jhonn Aguiar Schwyn]

I make some test..
I make a for to get the complete list of sprites..
    def set_layer(self, layer=None):        ''' Set the layer for a sprite '''        self._sprites.remove_from_list(self)        if layer is not None:            self.layer = layer
        # print all sprites list        print 'list:'        for i in range(self._sprites.length_of_list()):            a = self._sprites.get_sprite(i)            print 'sprite', a
        for i in range(self._sprites.length_of_list()):            a = self._sprites.get_sprite(i)            if layer < a.layer:                self._sprites.insert_in_list(self, i)                self.inval()                return        self._sprites.append_to_list(self)        self.inval()
With this, I corroborate that in a few cases, the list have None sprites:
list:sprite <TurtleArt.sprites.Sprite instance at 0x91d586c>sprite <TurtleArt.sprites.Sprite instance at 0x98d4fec>sprite <TurtleArt.sprites.Sprite instance at 0x98d8a2c>sprite <TurtleArt.sprites.Sprite instance at 0x98d8ccc>sprite <TurtleArt.sprites.Sprite instance at 0x98da14c>sprite <TurtleArt.sprites.Sprite instance at 0x98da54c>sprite <TurtleArt.sprites.Sprite instance at 0x98da9ec>sprite <TurtleArt.sprites.Sprite instance at 0x98dadac>sprite <TurtleArt.sprites.Sprite instance at 0x98de22c>sprite <TurtleArt.sprites.Sprite instance at 0x98de5ec>sprite <TurtleArt.sprites.Sprite instance at 0x98de9ec>sprite <TurtleArt.sprites.Sprite instance at 0x98dee2c>sprite <TurtleArt.sprites.Sprite instance at 0x9d2e2ac>sprite <TurtleArt.sprites.Sprite instance at 0x9d2e66c>sprite <TurtleArt.sprites.Sprite instance at 0x9d2ea2c>sprite <TurtleArt.sprites.Sprite instance at 0x9d2ee2c>sprite <TurtleArt.sprites.Sprite instance at 0x9d3228c>sprite <TurtleArt.sprites.Sprite instance at 0x9d326ec>sprite <TurtleArt.sprites.Sprite instance at 0x9d32aac>sprite <TurtleArt.sprites.Sprite instance at 0xa0d5d4c>sprite <TurtleArt.sprites.Sprite instance at 0x98cc1ec>sprite <TurtleArt.sprites.Sprite instance at 0x98cc52c>sprite <TurtleArt.sprites.Sprite instance at 0xa0d274c>sprite <TurtleArt.sprites.Sprite instance at 0xa0d2acc>sprite <TurtleArt.sprites.Sprite instance at 0xa0d2e6c>sprite <TurtleArt.sprites.Sprite instance at 0xa0d524c>sprite <TurtleArt.sprites.Sprite instance at 0xa0d562c>sprite <TurtleArt.sprites.Sprite instance at 0xa0d5a8c>sprite <TurtleArt.sprites.Sprite instance at 0xa0cf0ac>sprite <TurtleArt.sprites.Sprite instance at 0xa0cf46c>sprite <TurtleArt.sprites.Sprite instance at 0xa0cf82c>sprite <TurtleArt.sprites.Sprite instance at 0xa0cfbec>sprite <TurtleArt.sprites.Sprite instance at 0xa0d52ac>sprite <TurtleArt.sprites.Sprite instance at 0x9d5542c>sprite <TurtleArt.sprites.Sprite instance at 0x9d5578c>sprite <TurtleArt.sprites.Sprite instance at 0x9d55b2c>sprite <TurtleArt.sprites.Sprite instance at 0x9d55f8c>sprite <TurtleArt.sprites.Sprite instance at 0x9d583ac>sprite <TurtleArt.sprites.Sprite instance at 0x9d587ec>sprite <TurtleArt.sprites.Sprite instance at 0x9d58bcc>sprite <TurtleArt.sprites.Sprite instance at 0x9d58fcc>sprite <TurtleArt.sprites.Sprite instance at 0x9d5b44c>sprite <TurtleArt.sprites.Sprite instance at 0x9d5b84c>sprite <TurtleArt.sprites.Sprite instance at 0x9d5bcac>sprite Nonesprite Nonesprite Nonesprite Nonesprite Nonelist:sprite <TurtleArt.sprites.Sprite instance at 0x91d586c>....
Attach the part of the logs...
For solve the problem, attach a patch that only check for the None sprites..
The question is: why are None sprites in that list?
Who insert the sprites in the list?
Regards!
