Two things I don't understand:
1. How did you figure out that you could use vecs := _X; in addPolygon?
2. What is forcing the new polygons into position?

Me neither, I don't understand anything, but my goal with polygons is to make them deformable AND proceduraly generated terrain based on seed
1. Idk, just type scene.addPolygon, console will tell you it needs either vecs or surfaces, idk the difference, looks like surfaces have one extra pair of brackets
2. "material velocity" of plane and friction cause newly spammed terrain to go left, after 5 seconds they stick to background, after 40 seconds they turn red, then despawn (15s), totally 60s of life per track segment
Is that what you were asking? If not, contact me outside algobox comments, I'd like to chat with you
