Here's what I do:
# Set default projection to use upper left as origin
pyglet.gl.glMatrixMode(pyglet.gl.GL_PROJECTION)
pyglet.gl.glLoadIdentity()
pyglet.gl.glOrtho(0.0, 1024.0, 768.0, 0.0, -1.0, 1.0)
pyglet.gl.glMatrixMode(pyglet.gl.GL_MODELVIEW)
pyglet.gl.glLoadIdentity()
This makes 0,0 the upper left corner of the screen and 1024, 768 the
bottom right corner. But if you're thinking that this is what you
want, you should consider what will happen! If you use any function
that is not expecting this, it will draw upside down. For example,
try drawing some text using:
label = pyglet.text.Label('Hello, world',
font_name='Times New Roman',
font_size=36,
x=window.width//2, y=window.height//2,
anchor_x='center', anchor_y='center')
label.draw()
It will come out beautifully rendered in the right location, but
reflected upside down.
