there shouldn't be anything missing.

i use some assets from the gamestudio folder. maybe you have to adapt some paths like this one:

add_folder("C:/Program Files (x86)/GStudio7/projects/carlevel")



...and i think the current version of the wrapper lacks the ang() function. if you need it just define it yourself until i upload the next version.

Code:
def ang(x):
    return cycle(x, -180, 180)
