Is there a way to tell if a mouse button is being held down? I know there is a mouse button click function, but is there any functionality to tell if a mouse button is being held down?

Thanks!

if (Ms.b(0)) {
// Lightbulb?
}

In the headers you also get:

Bool b (Int x) {return BUTTON_ON(button[x]);} // if button 'x' on
Bool bp(Int x) {return BUTTON_PD(button[x]);} // if button 'x' pushed
Bool br(Int x) {return BUTTON_RS(button[x]);} // if button 'x' released
Bool bd(Int x) {return BUTTON_DB(button[x]);} // if button 'x' double clicked

Thank you very much Chris!
