Name

loop()

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().

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()
}

Syntax

  • loop()

Return

  • void
