Is there any way I can flip the coordinate system in Pyglet vertically so that y = 0 is at the top of the screen and a higher y value is closer to the bottom? It is really confusing trying to use Pyglet's flipped coordinate system with Ogmo Editor.
Just use the maximum height of the window for your calculations:
py_Y_Value = max_Screen_Height - my_Y_Value
or when getting:
my_Y_Value = max_Screen_Height - py_Y_Value
The best way to utilize these would be to abstract away their use in wrapper functions.
