To make an object move towards the mouse in p5.js, you can use the following code:

  1. Create a class for the object you want to move towards the mouse, for example:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16
17
18
19
20
class Object {
  constructor(x, y) {
    this.x = x;
    this.y = y;
  }

  moveTowardsMouse() {
    let dx = mouseX - this.x;
    let dy = mouseY - this.y;
    let angle = atan2(dy, dx);
    
    this.x += cos(angle) * 5;
    this.y += sin(angle) * 5;
  }

  display() {
    fill(255);
    ellipse(this.x, this.y, 20, 20);
  }
}


  1. Create an instance of the object and call the moveTowardsMouse() method inside the draw() function:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
let obj;

function setup() {
  createCanvas(400, 400);
  obj = new Object(width/2, height/2);
}

function draw() {
  background(0);
  obj.moveTowardsMouse();
  obj.display();
}


In this code, the object will continuously move towards the mouse cursor at a speed of 5 pixels per frame. You can adjust the speed by changing the value 5 in the moveTowardsMouse() method.
