Spawn Points and Center of Mass!

I actually started redoing my phsyics from scratch ( of course keeping the fundamentals and functions/formulas). I added a simple blue center of mass visual for the full body. Also, the spawn locations should work and then next I might be able to get back into reformatting the phsyics for gravity and then air and water, and etc then BOOM, we can start building stuff again! ALso, Ill add different parts! Wheels, motors, springs, all kinds of good stuff. NOTE: IF YOU HAVE ANY IDEAS FOR PARTS< LET ME KNOW! I MIGHT INCLUDE THEM!
