// THE NATURE OF CODE// Exercise 0.3// Create a random walker with dynamic probabilities. For example, can you give it a 50 percent chance of moving in the direction of the mouse?// by Alexander Oddenfunction setup() { class Walker { constructor() { this.x = width/2; this.y = height/2; } step() { let r = random(1); if (r < 0.5) { if (this.x < mouseX) { this.x++; } else if (this.x > mouseX) { this.x--; } // follow mouse x if(this.y < mouseY) { this.y++; } else if (this.y > mouseY) { this.y-- } // follow mouse y // otherwise move randomly } else if (r < .625) { this.x++; } else if (r<.75) { this.x--; } else if (r<.875) { this.y++; } else this.y-- } // step show() { stroke( 255 * abs(sin(this.x/70)), //R 255 * abs(cos(this.y/80)),//G 255 * abs(sin(this.y/60)) //B ); let d = abs(dist(this.x, this.y, mouseX, mouseY)); strokeWeight(sqrt(d)*2); point(this.x, this.y) } } createCanvas(600, 600); background(30); walker = new Walker() }function draw() { walker.step() walker.show()}
