Name

mouseClicked()

Description

The mouseClicked() function is called after a mouse button has been pressed and then released.

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 within the image to change 
    // the value of the rectangle after
    // after the mouse has been clicked
    
    int value = 0;
    
    void draw() {
      fill(value);
      rect(25, 25, 50, 50);
    }
    
    void mouseClicked() {
      if (value == 0) {
        value = 255;
      } else {
        value = 0;
      }
    }
