A Robot Arm is a programming test where you have a jointed arm, and have it extend to where you click, without the two sections changing length. It will therefore have to bend. This is useful for animators if you want two arm sections to move realistically. If you want it to bend the other way, go to the pen sprite and change the rotate 90 degrees. It uses basic trigonometry that most people know how to do (Pythagorean Theorem)
Some person told me to use sine But I didn't need it. So credit to him, sort of. Code by me. Point towards x: y: block from a different project of mine that you can look at. What is RTS? It stands for Random Trigonometry Stuff.
