Name

keyReleased()

Description

The keyReleased() function is called once every time a key is released. The key that was released will be stored in the key variable. See key and keyCode for more information.

Mouse and keyboard events only work when a program has draw(). Without draw(), the code is only run once and then stops listening for events.

Examples

  • // Click on the image to give it focus,
    // and then press any key.
    
    int value = 0;
    
    void draw() {
      fill(value);
      rect(25, 25, 50, 50);
    }
    
    void keyReleased() {
      if (value == 0) {
        value = 255;
      } else {
        value = 0;
      }
    }
