Im trying to code this catch game i p5, and i cant figure out how i can detect the falling objekt with the “basket” i’ve drawn…

hope you guys can help

```auto
let box1_x;
let box1_y;
let box1

let box2_x;
let box2_y;
let box2_w;
let box2;

let score;

function setup() {
  createCanvas(800, 800);
  
  box1_x = 400;
  box1_y = 100;
  box1 = box1_x*box1_y;
  
  
  
  box2_x = mouseX;
  box2_y = 700;
  box2_w = 100;
  box2 = box2_x*box2_y;
  
  
  score = 0;
}

function draw() {
  background(220);
  
  
  //red
  fill(255,0,0)
  rectMode(CENTER)
  rect(mouseX,box2_y,box2_w,50)
  
  
  //green
  fill(0,255,0)
  rectMode(CENTER)
  rect(box1_x,box1_y,25,50)
  //the box is falling
  box1_y += 5;
  
  //get the box back up again
  if (box1_y>box2_y){
    box1_y=0;
  }
  
  if (box2_x>box1_x>box2_w){
    score += 1;
    print(score)
  }
}

```

Hi @gp-gp, hope that the link to the Collision Detection book was helpful to you.

@GoToLoop – interesting, is CrHallberg’s site a translation of Jeff Thompson’s site into JavaScript?
