clear()

Clears all cells in the quadrille, setting each cell to empty (i.e., null).

Example

(click or press any key to toggle between clearing all cells and resetting to random colors)

code

Quadrille.cellLength = 20;  
let quadrille;  
let cleared = false;  

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

function draw() {  
  background(0);  
  drawQuadrille(quadrille);  
}  

function mouseClicked() {  
  cleared = !cleared;
  cleared ? quadrille.clear() : reset();
}  

function keyPressed() {  
  cleared = !cleared;
  cleared ? quadrille.clear() : reset();
}

function reset() {  
  quadrille = createQuadrille(20, 20, 100, color('red'));  
  quadrille.rand(100, color('lime')).rand(100, color('blue'));
}

ℹ️

Empty cells appear black because the background is set to black (background(0)).
