// reading zoom levels appears to be different for all browsers (if possible at all)

// i thought it would be easier to disable browser zoom and instead hardcode

// a pinch zoom in p5

so far, it appears p5 can detect multiple simultaneous mouse/finger presses

but the problem is that it only reads the coordinates of one and i dont think

there is any way to access the coords of the others

​

​

let touch = 0;

let i;

​

function setup() {

  createCanvas(400, 400);

  textSize(20);

}

​

function draw() {

  background(220);

  for(i=0;i<touch;i++){

    text(i,20,20+i*20);

  }

  text("X: " + mouseX,width-100, 20);

  text("Y: " + mouseY,width-100, 40);

}

​

function mousePressed(){

  touch++;

}

​

function mouseReleased(){

  touch--;

}
