PUSH ME AND THEN JUST TOUCH ME UNTIL I GET MY... COLLISSION.
This addon is literally the easiest way to create collision for Source I've ever witnessed. It's simple and effective. While also letting you get into some of the settings deeper if desired.
The creator is super helpful and will basically entertain any question no matter how stupid I am.
