I was working on some buggy "bounce" code (https://scratch.mit.edu/projects/1179827047) and couldn't figure out why it was failing at shallow bounce angles. This demonstrates why. "Moving" at an angle is a little erratic. Some angles are worse than others. Scratch must be doing the required trig, and then "rounding" to the nearest x,y location before rendering, which causes a "zig-zag" motion. Scratch must be doing "touch" detection based on rendered location rather than calculated location. A 45 deg. angle is smoother than a 20 deg. angle. I show both.
