I am trying to check the possibilities of DirectPython by converting the
DirectX tutorials to Python.
Can you tell me what's wrong with the following example ?
The sprite rotates but the triangle stays in place.
I have downloaded the source-code but could not find a way to compile it.
Am I missing some makefiles or is there a trick to compile the sources ?
Regards,
Gert
