触摸事件没有被删除，无论我在哪里触摸屏幕，都可以继续工作

Question

我有一个单词搜索游戏，有令牌，用户可以使用它们来揭示他们必须找到的单词。但我的问题是，我点击了令牌之后，我无法突出显示在搜索词中找到的单词，而是每次点击时都会留下一个令牌，无论在哪个级别上。我试图令牌：removeEventListener但没有工作，也许我把它放在了错误的地方

function token:touch(event) 
if event.phase == "began" then 
if storyboard.state.score >0 then 
    storyboard.state.score = storyboard.state.score - 1 
    score.text = tostring(storyboard.state.score) 
    clueText.isVisible = false 
    answerText.isVisible = true 
    display.getCurrentStage():setFocus(event.target) 
    event.target.isFocus = true 
elseif event.target.isFocus then 
    if event.phase == "moved" then 
     print("user has moved their finger off the token.") 
    elseif event.phase == "ended" then 
     print("user has used a token") 
     display.getCurrentStage():setFocus(nil) 
     event.target.isFocus = false 
    end 
end 
return true 
end 
end 
menubutton:addEventListener("touch", menubutton) 
token:addEventListener("touch", token) 

任何想法？

尝试修改你的函数是这样的：

function tokenTouch(event) 
    if event.phase == "began" then 
     if storyboard.state.score >0 then 
      storyboard.state.score = storyboard.state.score - 1 
      score.text = tostring(storyboard.state.score) 
      clueText.isVisible = false 
      answerText.isVisible = true 
      display.getCurrentStage():setFocus(event.target) 
      event.target.isFocus = true 
     end 
    elseif event.target.isFocus then 
     if event.phase == "moved" then 
      print("user has moved their finger off the token.") 
     elseif event.phase == "ended" then 
      print("user has used a token") 
      display.getCurrentStage():setFocus(nil) 
      event.target.isFocus = false 
     end 
    end 
    return true 
end 
token:addEventListener("touch", tokenTouch)

如果你想删除你的监听器，你必须在添加监听器后添加删除监听器。

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

       elseif event.phase == "moved" then 

       elseif event.phase == "ended" then 
       end 
     return true 
     end 
     token:addEventListener("touch",token) 


token:removeEventListener("touch",token)
