Re: error trying to load sprites

[Linus Heckemann]

Python 3 broke reverse compatibility to 2.x versions. I'm not sure, but it's likely that pyglet simply doesn't work on Python 3.x.

I'm trying to learn pyglet, and have installed 1.2alpha with python3.3.2 64bit edition.

I have a simple script for loading an image form a sprite sheet and displaying it as a large map.

class grid(pyglet.image.ImageGrid):

    def __init__(self, sprite):

        super(grid, self).__init__(sprite, 3, 1, 96, 96)

class map_tile(pyglet.sprite.Sprite):

    def __init__(self, file):

        super(map_tile, self).__init__(pyglet.resource.image(file))

    

class screen(pyglet.window.Window):

    def __init__(self, w, h):

        super(screen, self).__init__(w, h)

        self.clock = pyglet.clock.ClockDisplay()

        pyglet.clock.schedule_interval(self.update, 1/60.)

        

        raw = pyglet.image.load('images/map_sprites.png')

        raw_seq = pyglet.image.ImageGrid(raw, 3, 1, 96, 96)

        

        self.batch = pyglet.graphics.Batch()

        self.collection = []

        x, y = 0, 0

        

        for i in range(100):

            for j in range(100):

                sprite = pyglet.sprite.Sprite(raw_seq[2], batch = self.batch)

                sprite.x = x

                sprite.y = y

                self.collection.append(sprite)

                x += 96

            y += 96

            x = 0

        

    def update(self, dt):

        pass

        

    def on_draw(self):

        self.clear()

        self.batch.draw()

        self.clock.draw()

        pyglet.clock.tick()

if __name__ == '__main__':

    s = screen(1600, 900)

    pyglet.app.run()

However, when trying to run this, I get the following error:

Traceback (most recent call last):

  File "C:\Python33\lib\site-packages\pyglet\__init__.py", line 332, in __getattr__

    return getattr(self._module, name)

AttributeError: 'NoneType' object has no attribute 'ImageGrid'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

  File "C:\Users\Pittler\Desktop\Dev\extra\pyglet experimentation\bullet_client.py", line 12, in <module>

    class grid(pyglet.image.ImageGrid):

  File "C:\Python33\lib\site-packages\pyglet\__init__.py", line 338, in __getattr__

    __import__(import_name)

  File "C:\Python33\lib\site-packages\pyglet\image\__init__.py", line 189

    except codecs.ImageDecodeException, e:

                                      ^

SyntaxError: invalid syntax

The program worked fine in python2.7 32bit, but now it's not working. What might the problem be and how do I fix it?

I believe it mostly does work, provided you run it through the 2to3 tool. Someone else around here should know for sure, though...

Trunk supports it via 2to3 with manual work which went into making it work the rest of the way.  If you run setup.py build in python3 with your build dir deleted, it should do the rest for you.
