I was thinking about a 2-D map, like a 2-D bound or something, where there's bounds where like you have to walk onto a floating platform, or you can fall and die.(Like mario games) Could there be a simple way of setting up a jumping system or making is that have to stay on the ground?
I was thinking that to make them stay on the ground the air could be walk-able null so if you figure out a way to make jumping work you could teleport them into the null while they are 'in the air' and then they can't normaly go in the air.
