Not official build - debug mode on request of helper. (credits etc are not here) please see 0.7 for official current game. E to get out of the tank, e to get back in (only works If your touching the tank) notice the errors from there :)
as you can see, when you get out of the tank it goes to the starting place, it needs to go to where it was just before you got out. when the tank is out of frame, it follows the camera, it also seems to do a funky dance while you move, I don't know if changing the controls for walking to make them different to the tank would fix this. I'll have to test that.
