Inspiration from former exercise:

https://editor.p5js.org/LunaChen/full/ElUF-foL2

Using the float number between 0~1 to be the percentage of chance each state of moving.

step() {
let r = random(1);
//40% chance of moving to the right
if (r < 0.4) {
this.x++;
} else if (r < 0.6) {
this.x--;
} else if (r < 0.8) {
this.y++;
} else {
this.y--;
}
}

Use noise in random walker:

Not “Perlin noise”, but “value noise”

(OpenSimplexNoise, value noise, gradient noise, simple noise, worley noise…..)

noise() = = random()

Worley noise蜂窝

x+=random(-1,1);
