Arrow keys to change angle Change the 'Shape' slider at the top right to change shape Click the options to change thickness, or change the angle through the sliders. If you wish to use this engine, copy the scripts, and change the coords in the purple section of the long script.
Thanks to @Eriquito360 for help with the rotating script (the sin(),cos(),tan() one, I have no idea how they work), I did the different shapes More shapes coming soon! Comment and say what you think about it, and any shapes that you think should be added (The shape can't have any curved edges).
