Can I make a condition for the setup() and draw() to execute?

rebelL1ON

Hello, Maybe it's a dumb question, but is there a way to make a condition before setup() and draw()? (I want to make "Press space to start the game" -game that is in my sketch- ) Maybe I could do it in the draw() too but I don't know how to do it.

Thank you in advance. :)

How are you going to print the message if you haven't called setup()?

The traditional way is to set a flag in setup, check it on draw, draw the "press start" until the key is pressed and the flag is changed.

Keypressed () in the reference.

Could you give me an example? I didn't manage to do it :'(

var flag = false;

function setup() {
  createCanvas(800, 600);
}
function draw() {
  background(128);
  if (!flag) {
    text("press a key to start", 100, 100)
  } else {
    text("game on", 100, 100);
  }
}

function keyPressed() {
  flag = true;
}

That's what I tried but I made an error when typing curly brackets. That's what I get for trying this so late. Anyways thanks for your intelligent answer to a dumb question. Have a good day.
