Unity功能——宏定义的使用
文章目录
一.开发环境
Unity 版本无限制
VS 版本无限制
二.问题描述
仅在对应平台(PC/Android/IOS等)运行对应代码
三.宏的使用原理及代码格式.
实现原理:
添加对应宏定义,达到定义内代码在对应平台运行.
对应代码:
在函数(方法)内使用# if +对应宏为开头,以 #endif为结尾,可以使用elif /else等.
#if UNITY_EDITOR
Debug.Log("Editor");
#elif UNITY_STANDALONE
Debug.Log("UNITY_STANDLONE");
#elif UNITY_ANDROID||UNITYIOS
Debug.Log("UNITY_ANDROID||UNITY_IOS");
#endif
Debug.Log("DoubleTap");
如图一所示.

五.自定义宏
除了默认的宏定义外,可以通过Unity自定义宏
5.1 Unity中自定义宏操作:
BuildSettings(Ctrl+Shift+B)——PlayerSettings——OtherSettings——Scripting Define Symbols
多个宏定义用 ; (分号)隔开;
注意事项:打包(构建)测试时,如果使用了测试才用的自定义宏,正版发布版本别忘了取消.
六.总结
保持饥饿,保持愚蠢.
这世界唯一能够相信的就是你付出的努力和你走过的路.
