Collision chart

I made a collision chart for myself, as reference. If you could take a quick look at it and check that I didnt make any mistakes, that’d be great.

Does red means slow in terms of performance?

Grey is never, some of them cant be INTO, some of them cant be FROM.
Red is invalid FROM … INTO … combination, for stuff that does have valid other combinations.

It’s entirely based on the chart here. But alphabetically and with the omitted things added in.

Is it internal panda3d physics engine or bulletphysics?
