If you get no collisions, you have a wrong setup. For instance, you move an object that is neither kinematic nor a character. Collisions are supported for character controllers and kinematic objects only. Other possibilities are that your object penetrates the ground, or that you've set some strange physics flags.

Just begin with the very simple example from the link that I posted. It's only a few lines of code and shows you all 4 movement methods. Also check which version you're using - pxent_moveglobal for chars is only supported in 8.20.
