小功能⭐️Unity动态更改 Scripting Define Symbols (宏定义)

#if UNITY_EDITOR
 
//获取当前是哪个平台
BuildTargetGroup buildTargetGroup = EditorUserBuildSettings.selectedBuildTargetGroup;
 
//获得当前平台已有的的宏定义
var symbols = PlayerSettings.GetScriptingDefineSymbolsForGroup(buildTargetGroup);
            
//添加你想要的宏定义
if (!symbols.Contains("SARF"))
{
    string str = "";
    str = symbols + ";SARF";
 
    PlayerSettings.SetScriptingDefineSymbolsForGroup(buildTargetGroup, str);
}
 
#endif
