# Click within the image to change # the value of the rectangle after # after the mouse has been clicked value = 0 def draw(): fill(value) rect(25, 25, 50, 50) def mouseClicked(): global value if value == 0: value = 255 else: value = 0
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.
