Double click green flag to start simulation. This is a simulation of some solar system. It uses simple Newtonian laws to describe how the planets move and interact. Use the up arrow key to thrust the engines of the the solar probe, and the left and right arrow keys to change the direction. It is recommended to disable turbo mode while operating the probe. Don't consider this debugged; loads of glitches to be fixed. Use turbo mode (shift-click green flag) for faster speed of the planetary movement.
For a collaboration with @Alavacomgetepus UPDATE LOG: ---- 2016-07-22: M, Added probe animation and arrow key thrust (with gravity), and changed the name to GravitySystem instead of GravitationalSystem because it was too long. Future versions will also have this name. ---- 2016-07-22: A, Added probe physics (gravity pull from sun and planets).
