fill(row, col, value, border)

Fills a specific cell and all connected cells in the quadrille with the specified value using a flood fill algorithm. The border parameter determines if the fill includes the boundary of the flood fill area.

Example #

(click on any cell to perform flood fill with selected border option; press any key to reset)

code

Quadrille.cellLength = 20;  
let quadrille;  
let mode;  

function setup() {  
  createCanvas(400, 400);  
  mode = createSelect();  
  mode.option('flood fill without border');  
  mode.option('flood fill with border');  
  mode.selected('flood fill without border');  
  reset();  
}  

function draw() {  
  background('black');  
  drawQuadrille(quadrille);  
}  

function mouseClicked() {  
  const row = quadrille.mouseRow;  
  const col = quadrille.mouseCol;  
  const border = mode.value() === 'flood fill with border';  
  quadrille.fill(row, col, 255, border);  
}  

function keyPressed() {  
  reset();  
}  

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