noise_seed()

Sets the seed value for noise().

Examples

def setup():
    py5.noise_seed(42)
    py5.stroke(0, 10)


def draw():
    n = py5.remap(py5.noise(py5.frame_count / 100), 0, 1, 0, py5.width)
    py5.line(n, 0, n, py5.height)

def setup():
    global xpos, ypos
    py5.rect_mode(py5.CENTER)
    py5.noise_seed(42)
    xpos = py5.width / 2
    ypos = py5.height / 2


def draw():
    global xpos, ypos
    py5.background(128)
    xpos = (xpos + py5.noise(py5.frame_count / 250) - 0.5) % py5.width
    ypos = (ypos + py5.noise(500 + py5.frame_count / 250) - 0.5) % py5.height
    py5.square(xpos, ypos, 25)

Description

Sets the seed value for noise(). By default, noise() produces different results each time the program is run. Set the seed parameter to a constant to return the same pseudo-random numbers each time the Sketch is run.

Underlying Processing method: noiseSeed
