Blobby effect using helper functions from the Two.js library.
function change(part, attr, min, max, deltaMin, deltaMax, x) {
let delta = Math.random() * (deltaMax - deltaMin) + deltaMin;
if (part[x]) {
part[attr] += delta;
} else if (!part[x]) {
part[attr] -= delta;
}
if (part[attr] <= min) {
part[x] = true;
} else if (part[attr] >= max) {
part[x] = false;
}
}
