Red rules are the sound rules
Sounds nearly always belong in red rules, the ones that happen once at a moment: Collides with, Upon pressing a key, Lands on the ground. A rule that is true all the time, like Is overlapping, would start the sound sixty times a second. That makes a horrible buzz. If a sound sticks or stutters, that is why. See Red rules happen once.
