1s1s1p = 1 sprite, 1 script, 1 pixel. In other words, everything is drawn by pen. Repost of an older project- For Design Studio. Use the arrow keys to move one ball. Per suggestion of Sky01, you can click and drag to move around balls. Press space to give both balls random velocities. 2 balls interacting with gravity. The physics here, unlike before, ARE accurate. Hopefully, I will incorporate elastic physics when I get around to remaking Airhockey.
