I haven't posted any contributions lately, so I thought I'd post this (As requested).
It's still the OLD version of Newton, just adapted to work with the newer versions of A6 (A6.5). I have also added my first attempt at a physics player. The old Newton examples simply used a regular entity, so it wasn't interactable with Newton. Mine is (Somewhat... lol).
Thise is only the first version... Much more work to come along in the future. If you want to contribute to this, then please let me know and I'll add it in.
Here it is:
