[

let unicorn =createSprite(20,20,20,20);

function setup() {
  createCanvas(400, 400);
}

function draw() {
  background(220);
  unicorn.show();
}

]1I cannot figure out what's wrong out here . The results in the console are showing that the basic functions like "createSprite" or the "show" functions are undefined . what can be the possible reason behind this? Am i supposed to add any library here ? If yes so from where can i get it ?/
