This function is not supported in earlier versions.

Callback function triggered when a touch press moves inside the touch screen.

Function

Synopsis

love.touchmoved( id, x, y, dx, dy, pressure )

Arguments

light userdata id
The identifier for the touch press.
number x
The x-axis position of the touch inside the window, in pixels.
number y
The y-axis position of the touch inside the window, in pixels.
number dx
The x-axis movement of the touch inside the window, in pixels.
number dy
The y-axis movement of the touch inside the window, in pixels.
number pressure
The amount of pressure being applied. Most touch screens aren't pressure sensitive, in which case the pressure will be 1.

Returns

Nothing.

Notes

The identifier is only guaranteed to be unique for the specific touch press until love.touchreleased is called with that identifier, at which point it may be reused for new touch presses.

The unofficial Android and iOS ports of LÖVE 0.9.2 reported touch positions as normalized values in the range of [0, 1], whereas this API reports positions in pixels.
