fill(bitboard, value, littleEndian?)

Fills the quadrille based on a bitboard pattern passed as a JavaScript BigInt. Each 1 bit in the binary representation corresponds to a filled cell with the given value. The bitboard is read in row-major order, using big-endian by default.

To use little-endian ordering instead, pass true as the third argument.

Example #

(click to toggle the smiley bitboard pattern)

code

Quadrille.cellLength = 50;

let quadrille;
let smileyOn;

const SMILEY = 0b0000000_0110110_0001000_0001000_0100010_0011100_0000000n;

function setup() {
  createCanvas(350, 350);
  quadrille = createQuadrille(7, 7);
}

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

function mousePressed() {
  smileyOn ? quadrille.clear() : quadrille.fill(SMILEY, color('black'));
  smileyOn = !smileyOn;
}

Syntax #

fill(bitboard, value[, littleEndian])

Parameters #

Param	Description
`bitboard`	BigInt (or Number): A bitboard whose binary representation determines the filled cells
`value`	Any: A valid JavaScript value (e.g. string, number, object, function) to assign to filled cells
`littleEndian`	Optional Boolean: If `true`, the bitboard is interpreted in little-endian order (default is `false`)
