Randomly generate a 2D plain of terrain! If you are not very patient, I would recommend not putting in a high world size. The higher, the longer it takes to load.
=== CREDITS === All made by me, @D0MBOM === Q&A === What are the purple lines? The purple lines are chunk boundaries. What are chunks? A chunk is how much area is flattened. Why does it flatten the world? After you run the project and enter a specified "world length", the code then generates it, and then goes into the boring process of flattening the terrain. The terrain is "flattened" to give more of a hilly aesthetic. How can I remove the "hilly" look? You can remove the flattening process if you click "see inside", go to the draw world definition and remove the four "if" statements at the bottom, then run the project.
