  • Just show the relevant code. i.e. the touch listener and your timer. I may be able to help you out if you show the code. – JLONG Jun 27 '15 at 08:07

Sorry for the delay. I noticed that you are not clearing the Focus on the object you are dragging. You must first clear the focus of your previous touch listener in order for the code to recognize a new touch even if you removed the event listener the focus is still there: 

local objectTouched --This is to get the event.target.id that you will use later assuming that your event.target.id is a number

local function dragAndDrop (e)

    target = {}
    distanceBetweeen = {}

    objectTouched = event.target.id

    for i = 1, #checkPoint do 
        target[i] = checkPoint[i]
    end


        if e.phase == "began" then

            --YOUR CODE

        elseif e.phase == "moved" then

            --YOUR CODE

        elseif e.phase == "ended" then

            --YOUR CODE

        elseif e.condition == "forceCancelled" then

             -- ADD THIS CONDITION SO THAT THE FUNCTION WILL REMOVE -- THE FOCUSED OBJECT FIRST

            display.getCurrentStage():setFocus(nil)

        end

end


function timeoutGame()
    --BEFORE YOU REMOVE THE EVENT LISTENER CALL THIS FIRST
    ilusi[objectTouched]:dispatchEvent({name = "touch", target = ilusi[objectouched], condition = "forceCancelled"})
    timeoutGroup.alpha = 1 
    timeoutGroup:toFront()
    btnPause:removeEventListener("tap", pauseGame)
    btnReload:removeEventListener("tap", goTo)

    for i=1, #jawabanPasti do
        ilusi[i]:removeEventListener ("touch",dragAndDrop)
    end   


end
