smth I made because I'm autistic, pretty much "yoyo simulator" :) the amplitude modifier is for how high / low you want the object to be. I set minimum to 50 (wow that rhymed) because setting it as an astronomically low value would make it basically... go out of existence.
uses trigonometry functions alongside a constant to simulate this. thought it'd be fun there isn't ACTUALLY a rope, but it's supposed to be an illusion that puts the object in the opposite position, as if there were a center of imbalance. this simulation automatically calculates the average size of the object, which is multiplied to the frequency of the rope to make it look realistic.
