Thanks!
Okay, reading the header for the physics file it makes more sense. However, everything with raymath.h isn't working either.
Similar issue with any example that uses another file besides raylib.h. For example, trying out physics_demo.c gives:
physics_demo.c:22:10: fatal error: physac.h: No such file or directory
I have tried on two separate windows computers. Ray, any workaround to this?
