The half-assed hoverboard, summon HoverBoard.xcHoverBoard to insert it.
Jump on it, crouch and start driving, can be destroyed as well.
Contains a platform that forwards damage as well, usage of Attach and Detach events, and usage of antigravity code, should work well on net games (not tested).
The hoverboard doesn't transfer velocity to jumps, get hit and say goodbye to it.
