module: [kind=event] mouse_click

This event is fired when the terminal is clicked with a mouse. This event is only fired on advanced computers (including advanced turtles and pocket computers).

Return values

1. [string]: The event name.
2. [number]: The mouse button that was clicked.
3. [number]: The X-coordinate of the click.
4. [number]: The Y-coordinate of the click.

Mouse buttons

Several mouse events ([mouse_click], [mouse_up], [mouse_scroll]) contain a "mouse button" code. This takes a numerical value depending on which button on your mouse was last pressed when this event occurred.

Button Code	Mouse Button
1	Left button
2	Right button
3	Middle button

Example

Print the button and the coordinates whenever the mouse is clicked.

  local event, button, x, y = os.pullEvent("mouse_click")
  print(("The mouse button %s was pressed at %d, %d"):format(button, x, y))
end
