Name

### delay()

Examples

    int pos = 0;
    void draw() {
      background(204);
      pos++;
      line(pos, 20, pos, 80);
      if(pos > width) {
        pos = 0;
      }
      delay(250);  // Stops the program for 250 milliseconds
    }

Description

Forces the program to stop running for a specified time. Delay times are specified in thousandths of a second. The function call delay(3000) will stop the program for three seconds.
Because the screen is updated only at the end of draw(), the program may appear to "freeze" until the delay() has elapsed.
This function causes the program to stop as soon as it is called, except if the program is running the draw() for the first time, it will complete the loop before stopping.

Syntax

    delay(milliseconds)

Parameters

milliseconds | int: specified as milliseconds (there are 1000 milliseconds in 1 second)

Usage | Web & Application
