cocos2dx简单弹窗实现_d a x c space弹窗-优快云博客

本文介绍了如何使用cocos2dx创建弹出窗口，并实现暂停功能。通过设置触摸级别，创建暂停游戏的场景，添加背景、暂停按钮以及继续和退出游戏的选项，实现了暂停游戏时在屏幕中央显示暂停窗口，以及点击按钮继续或结束游戏的逻辑。

回忆暑假，弹框的问题一直萦绕在我身边，我决心今夜来重新复习这个问题。回忆起当初共同探讨的时期还是十分怀念的。废话不多说。弹出框，顾名思义就是弹出一个窗口（一个Sprite纹理图片）；并且对下面的层触摸事件等没有影响。我就用暂停来实现这些功能。

首先面对弹出框，我们需要理解什么是触摸级别。触摸级别是cocos2dx触发触摸事件的优先级，级别越低，触摸的优先级越高，所以有菜单的触摸级别是-128，这已经是相当优先了。好了接下来我们试着去实现这些功能。
