Power drain, scanner and scrolling update

More game play to show. Added power drain system and based on attachments. At the moment only the tracks drain power based on speed. Added a scanner and converted scrolling to use uv offsets on 3d quads to make it easy to change direction with only 4 quads on the screen - no gaps. Will add connection system next so you can add more parts. https://www.youtube.com/watch?v=E0RBHgm-y2w
