Move object on touch

Unknown

Hi guys,
how can move an object just by touching the screen and it will move until i release my touch
i trying to do it by:
btn_right:addEventListener("click",
function ()
ship.xdirection = -1
local x = ship:getX()
x = x + (ship.xdirection * ship.xspeed)

if x < 0 then
ship.xdirection = -1
end

ship:setX(x)
end)
but it only moves it when i touch the screen , i need a flowing movement

Yours is not multi touch but the same logic. You need to use event ontouchmove not onclick.
