近日在用cocos2dx3.4的时候使用了JNI调用,发现一个现象 当不使用jni的时候全然正常.使用了jni后回去的全部文字都变成黑块,而且有概率程序崩溃.附带出了两个log call to OpenGL ES API with no current context 和 Fatal signal 11 但相同的cocos2dx ,相同的jni代码,还有一个项目却正常.找寻了好久之后发现了原因 cocos2dx 3.x以后版本号 不再是一个进程跑究竟: 引用:"Cocos2d-x从2.x版本号…
前言 在开发应用程序时,通常只让程序运行一个实例.所以,就要判断程序是否已经运行. 下面是我自己在项目中使用到,封装好的帮助类.有 普通的 C# 应用程序 和 Windows CE 和 Windows Mobile 应用程序使用的方法. 主要是通过 System.Threading.Mutex 类 和 Win32 API 来实现,下面就是各自的代码,调用示例在最后面. 普通 C# 应用程序 主要是 Windows 窗体应用程序和控制台程序. 1. 使用 System.Threading.Mute…
