Demo of a "Moon Lander" type of ship. The relative location of the Result Sprite with respect to the Ship is used to represent the Ship's Velocity Vector. The Pointer Sprite is used to track the angle and gives a display of where the ship is heading. Hiding the pointer would be more "realistic", but I left it visible to help illustrate what's going on. In this case, gravity is represented by a local variable in the Result Sprite as a small negative number, so gravity is "down". Left/Right Arrows to Turn, Up Arrow for Thrust
