In Unturned II I think that there should be player contact such as not being able to walk straight through another entity / player so if you are in a gun fight and you go inside of your teammate you don’t shoot them. Maybe make it so that if the two entities start going inside of each other they get pushed away kind of like Minecraft in the more earlier versions.
I’m pretty sure player collision is already in the game
Honestly, I expected this post to talk about more something like player communication, not just player collision.
And I think it might already be implemented.
