Name

mousePressed

Description

The mousePressed variable stores whether a mouse button has been 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);
}
