mousePressed

Description

The mousePressed() function is called once after every time a mouse button is pressed. The mouseButton variable (see the related reference entry) can be used to determine which button has been pressed.

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
    void draw() {
      if (mousePressed == true) {
        fill(0);
      } else {
        fill(255);
      }
      rect(25, 25, 50, 50);
    }
