Mouse drag (event)

The mouse_drag event occurs every time the mouse is moved until the user releases the mouse button. It will always occur after a mouse_click event. The event will only be fired when the mouse moves to another character position, dragging within the same character will have no effect.

Event mouse_drag
Fired when the mouse is dragged (implies that a mouse_click event has already occurred).
Returned Object 1	The mouse button that was clicked.
Returned Object 2	The X-coordinate of the mouse (in screen-characters).
Returned Object 3	The Y-coordinate of the mouse (in screen-characters).

Examples

Example
Print the new co-ordinates of the mouse every time a mouse_drag event occurs.
Code	while true do _, button, xPos, yPos = os.pullEvent("mouse_drag") print("mouse_drag => " .. tostring(button) .. ": " .. "X: " .. tostring(xPos) .. ", " .. "Y: " .. tostring(yPos)) end
Output	The X and Y position of the mouse during the drag.

Example
Draws a single pixel on the screen, which is moved to the mouse position when mouse is clicked and dragged on the screen
Code	x = 5 y = 5 while true do term.setBackgroundColor( colors.black ) term.clear() paintutils.drawPixel( x, y, colors.red ) event, button, xPos, yPos = os.pullEvent("mouse_drag") if button == 1 then -- left button was clicked x = xPos y = yPos end end
