Platform Dependent Compilation

【Platform Dependent Compilation】

1、Platform Defines

　　

2、在Project Setting -> Player 面板的Other Settings的Scripting Define Symbols可以自定义macro，在此片定义的macro会被所有代码引用。

　　

　　以分号分隔。

3、You can define your own preprocessor directives to control which code gets included when compiling. To do this you must add a text file with the extra directives to the "Assets/" folder. The name of the file depends on the language you are using, and the extension is .rsp:

　　

　　As an example, if you include the single line "-define:UNITY_DEBUG" in your smcs.rsp file the define UNITY_DEBUG will exist as a global define for C# scripts, except for Editor scripts.

　　smcs.exe路径：...\Unity\Editor\Data\Mono\lib\mono\unity
