Exploration in quadcopter control. First, click green flag to start project. Set control slider to 0 for manual controls and fly using arrow keys to change x and y acceleration. Set control to 1 for automatic non-proportional control (copter accelerates fully in x, y coordinates towards target), then click mouse to set target. Set control to 2 for automatic proportional control (copter accelerates proportionally to distance to target), and then click mouse to set target. Set control to 3 for "preemptive" proportional control, which notices changes in distance error, and decelerates as it reaches target to avoid overshoot. (Note: If you just set slider to 0, you must then click elsewhere off of the slider to enable manual control.)
