Synopsis
x, y = love.touch.getPosition( id )
Arguments
light userdata id
- The identifier of the touch-press. Use love.touch.getTouches, love.touchpressed, or love.touchmoved to obtain touch id values.
Returns
number x
- The position along the x-axis of the touch-press inside the window, in pixels.
number y
- The position along the y-axis of the touch-press inside the window, in pixels.
Notes
The unofficial Android and iOS ports of LÖVE 0.9.2 reported touch-press positions as normalized values in the range of [0, 1], whereas this API reports positions in pixels.
Examples
Draw a circle at each location in the window where a touch press is active.
function love.draw()
local touches = love.touch.getTouches()
for i, id in ipairs(touches) do
local x, y = love.touch.getPosition(id)
love.graphics.circle("fill", x, y, 20)
end
end
