It's getting a wrong type for argument 1. From what I can tell, this means
that when you're initialising the base Sprite, it's getting something else
for the blend function. Looking at the code, I suggest changing the super
call to this:
super(Level_1, self).__init__(img, x=x, y=y, batch=batch)
I'm not sure if that will error and I can't test now (it shouldn't). If it
does, do this:
super(Level_1, self).__init__(img, x, y, GL_SRC_ALPHA,
GL_ONE_MINUS_SRC_ALPHA, batch)
after importing * or the two GL_ things from pyglet.gl.
The reason is that YOUR sprite class has the order of __init__ variables
(img, x, y, batch), but if you look at a normal sprite, it goes (img, x, y,
blend_src, blend_dest, batch, ...). So you have to always remember to
compensate for that in your code.
