如何將觸摸的文本對象與某個對象的值進行比較？

Question

需要幫助。我在這裏有我的整個代碼。我試圖將觸摸的對象（文本）與局部變量答案的值進行比較，但它總是打印文本的零值。我怎樣才能比較這兩個？

function scene:create(event) 
    local sceneGroup = self.view 

    local temp1 = math.random(0,10) 
    local temp2 = math.random(0,10) 

     local answer = temp1 + temp2 


    local background = display.newImage("bg0.png") 
     background.x = display.contentWidth*0.5 
     background.y = display.contentHeight*0.5 



    local text2 = display.newText(temp1,90,45,"Arial",55) 
    text2:setFillColor(0, 0, 0) 
    local plus = display.newText(" + ",140,45,"Arial",55) 
    plus:setFillColor(0, 0, 0) 
    local text3 = display.newText(temp2,180,45,"Arial",55) 
    text3:setFillColor(0, 0, 0) 
    local equals = display.newText(" = ",235,45,"Arial",55) 
    equals:setFillColor(0, 0, 0) 


    local secondsLeft = 02 * 60 
    local clockText = display.newText("02:00", 270, -7, "Arial", 35) 
    clockText:setFillColor(0,0,0) 

    local function updateTime() 

     secondsLeft = secondsLeft - 1 

     local minutes = math.floor(secondsLeft/60) 
     local seconds = secondsLeft % 60 

     local timeDisplay = string.format("%02d:%02d", minutes, seconds) 
     clockText.text = timeDisplay 

     if timeDisplay == "00:00" then 
      GameOver() 
      print "Game Over!!!" 
     end 
    end 

    local countDowntimer = timer.performWithDelay(1000,updateTime,secondsLeft) 


    local function offscreen(self, event) 
     if(self.y == nil) then 
      return 
     end 

     if(self.y > display.contentHeight - 100) then 
      Runtime:removeEventListener("enterFrame", self) 
      self:removeSelf() 
     end 
    end 

    local function balloonTouched(event) 
     if (event.phase == "began") then 

      print("object touched =", event.target) 
      print (answer) 

      if event.target == answer then 
       print "Good" 

        local temp1 = math.random(0,10) 
        local temp2 = math.random(0,10) 

        local text2 = display.newText(temp1,90,45,"Arial",55) 
         text2:setFillColor(0, 0, 0) 
        local text3 = display.newText(temp2,180,45,"Arial",55) 
         text3:setFillColor(0, 0, 0) 
       secondsLeft = secondsLeft + 5 

      else 
       print "Wrong Answer" 
       secondsLeft = secondsLeft - 3 

      end 
      Runtime:removeEventListener("enterFrame", event.self) 
      event.target:removeSelf() 
     end 
     return true 
    end 

    local function ulit() 
     lobo = { ("blue.png"), ("green.png"), ("red.png"), ("orange.png"), ("pink.png"), ("violet.png"), ("yellow.png") } 
     local lobo = display.newImage(lobo[math.random(7)], math.random(35,260), 600) 
     physics.addBody(lobo, { density=0.1, friction=2.0, bounce=0.0, velocity=-40, isSensor=true }); 
     lobo.gravityScale = -0.1111111115 
      sceneGroup:insert(lobo) 
      lobo.enterFrame = offscreen 

     local text = display.newText(math.random(0,9),50,30,"Arial",40) 
     text.id = "sagot" 
      sceneGroup:insert(text) 
      text.enterFrame = offscreen 

      function lobo:enterFrame() 
       text.x, text.y = lobo.x, lobo.y; 
      end 
     Runtime:addEventListener("enterFrame", lobo) 
     lobo:addEventListener("touch", balloonTouched) 

    end 

    timer.performWithDelay(300,ulit,0) 

    local backBtn = widget.newButton 
    { 
     labelColor = { default={255}, over={128} }, 
     defaultFile= "home.png", 
     overFile= "home.png", 
     width=50, height=50, 
     onRelease = onBackBtnRelease  
    } 
    backBtn.x = 20 
    backBtn.y = -7 

    sceneGroup:insert(background) 
    sceneGroup:insert(clockText) 
    sceneGroup:insert(backBtn) 
    sceneGroup:insert(text2) 
    sceneGroup:insert(plus) 
    sceneGroup:insert(text3) 
    sceneGroup:insert(equals) 

end

嘗試（應該工作）

local function ulit() 
    local mRandom = math.random 
    local imagesNames = { "blue.png", "green.png", "red.png", "orange.png", "pink.png", "violet.png", "yellow.png" } 
    local lobo = display.newImage(imagesNames[mRandom(7)], mRandom(35,260), 600) 

    ... 

    local n = mRandom(0, 9) 
    local text = display.newText(n,50,30,"Arial",40) 
    lobo.number = n 
    ... 

local function balloonTouched(event) 

    ... 

    -- here event.target is equal lobo 
    if event.target.number == answer then 
    ... 

在ulit功能，您使用的表對象和diplay對象相同的名稱（lobo）。那是錯的。
