Value returned: the constant true if the mouse has been clicked sometime during the running of the current handler, or false if it hasn't.
If the mouse button is down, the mouseClick waits until the mouse button is up before returning true.
Note: Use the mouse to return the current state of the mouse button and the mouseClick to return whether the mouse has been clicked in the current handler.
