如何添加一個按鈕返回主菜單（另一個.lua文件）？

Question

這款遊戲就像殺死蚊子一樣。這是1級文件。當玩家點擊蜜蜂時，會顯示遊戲結束。當時間到了，遊戲結束會顯示。殺死的蚊子總數將顯示在最後。我對電暈和遊戲開發非常陌生。 我的問題是：

1. 在哪裏可以通過「觸摸」功能返回主菜單？它的代碼是什麼？
2. 我正在使用作曲家。所以我嘗試了composer.gotoScene（「菜單」），但似乎並不奏效。錯誤。

在此先感謝您提供的任何幫助。下面是部分代碼：

Answer 1

確保一幕被稱爲「menu.lua」當您嘗試使用composer.gotoScene("menu")

首先確保您所需要的庫頂部

local composer = require("composer") 
local widget = require("widget") 

然後添加一個監聽器將處理按鈕事件

local function handleButtonEvent(event) 
    if ("ended" == event.phase) then 
     composer.gotoScene ("menu") 
    end 
end 

然後創建按鈕

local myButton = widget.newButton 
{ 
    left = 100, 
    top = 200, 
    id = "myButton", 
    label = "Default", 
    onEvent = handleButtonEvent 
} 

編輯： 看你的代碼，我可以你實際上並沒有使用作曲家看到。當然，你可能會包括這些庫，但是你沒有設置任何工作所需的功能。

我建議你閱讀這篇文章：Introducing the Composer API。這將引導您完成作曲家的使用。

至少你應該有以下功能讓作曲家工作。

• 場景：創建（）
• 一幕：表演（）
• 場景：隱藏（）
• 場景：刪除（）

並在那些使用利用場景的看法local sceneGroup = self.view。一旦物體被正確插入，您可以「管理」您的場景和其中的顯示對象。
