| Examples |
void setup() {
size(200, 200);
noLoop(); // draw() will not loop
}
float x = 0;
void draw() {
background(204);
x = x + .1;
if (x > width) {
x = 0;
}
line(x, 0, x, height);
}
void mousePressed() {
loop(); // Holding down the mouse activates looping
}
void mouseReleased() {
noLoop(); // Releasing the mouse stops looping draw()
}

| Description | By default, Processing loops through draw() continuously, executing the code within it. However, the draw() loop may be stopped by calling noLoop(). In that case, the draw() loop can be resumed with loop(). |
| Syntax | loop() |
