[Unity]添加自定义宏 PlayerSettings.SetScriptingDefineSymbolsForGroup

一般我们都是在playersetting->Player-> ScriptsCompilcation添加宏定义

但是现在实现在脚本中定义：

using System.Linq;
using UnityEditor;
using UnityEngine;
#if UNITY_EDITOR
public class ScriptingDefineSymbolsTest 
{
    //在菜单栏中点击自动添加
    [MenuItem("Tool/AddScriptingSymbols")]
    private static void AddScriptingSymbols()
    {

        //获取当前是哪个平台
    BuildTargetGroup buildTargetGroup = EditorUserBuildSettings.selectedBuildTargetGroup;
        Debug.Log("buildTargetGroup" + buildTargetGroup);
        //获取当前平台已有的宏定义
        var symbols = PlayerSettings.GetScriptingDefineSymbolsForGroup(buildTargetGroup);
        Debug.Log("symbols" + symbols);
        //添加想要的宏定义
        var ss = symbols.Split(';').ToList();
        if (ss.Contains("UNITY_TEST"))
        {
            return;
        }
        ss.Add("UNITY_TEST");
        symbols = string.Join(";", ss);
        PlayerSettings.SetScriptingDefineSymbolsForGroup(buildTargetGroup, symbols);
       Debug.Log("添加后的宏：" + PlayerSettings.GetScriptingDefineSymbolsForGroup(buildTargetGroup));
    }
    [MenuItem("Tool/RemoveScriptingSymbols")]
    private static void RemoveScriptingSymbols()
    {
        //获取当前是哪个平台
        BuildTargetGroup buildTargetGroup = EditorUserBuildSettings.selectedBuildTargetGroup;
        //获取当前平台已有的宏定义
        string symbols = PlayerSettings.GetScriptingDefineSymbolsForGroup(buildTargetGroup);
        var ss = symbols.Split(';').ToList();
        //移除想要的宏定义
        if (!ss.Contains("UNITY_TEST"))
        {
            return;
        }
        ss.Remove("UNITY_TEST");
        symbols = string.Join(";", ss);
        PlayerSettings.SetScriptingDefineSymbolsForGroup(buildTargetGroup, symbols);
        Debug.Log("移除后的宏：" + PlayerSettings.GetScriptingDefineSymbolsForGroup(buildTargetGroup));
    }

}
