背景:

在游戏开发中不免需要加一些我们自己的功能宏定义比如DebugMod开发模式宏 方便进行gm开发，或者一些debugtool的开发，开发者一定要重视debugTool的开发

不然会面临很多测试上的难题，比如某个流程很长的功能一轮测试下来可能就要几分钟。

主类很简单其他忽略 但是我这边定义了一个逻辑位 DefineBit 这里主要可以学习到逻辑位操作的技巧。点击开启宏之后等待工程编译（使用接口CompilationPipeline.RequestScriptCompilation()）

等菊花转完之后就好了，同时之前显示的开启宏会变为关闭宏 ，再次点击按钮取消该宏定义，点击关闭所有宏定义会取消所有defineArray数组定义的所有宏

1.main.cs

public class Main : MonoBehaviour
{#if UNITY_EDITORpublic int DefineBit; 
#endif
}

2.编辑器类MainEditor.cs

using System.IO;
using Launcher;
using Runtime.Core.Constants;
using UnityEditor;
using UnityEditor.Compilation;
using UnityEngine;
using Application = UnityEngine.Application;
[CustomEditor(typeof(Main))]
public class MainEditor : Editor
{
bool SymbleDefine = true;
string[] defineArray = new string[]
{"",    "DebugMod","FRUIT_DEBUG","DEV_DEBUG_NET", // 网络调试   "VIP_DEBUG", // 测试vip   "UNITASK_DOTWEEN_SUPPORT", // DoTween UniTask"HOT_UPDATE_TEST", // 测试热更新   "DELIVERY_DEV_1_1_3",// 分包开发 "DEBUG_REDPACK",    "REMOTE_DEBUG", // 远程测试  "TEST_INPUT" , // 测试输入系统 "TEST_WELCOMEUI" , // 测试欢迎界面 "TEST_RANKMATCHEX" , // 测试排位赛"DEV_MODE",
};public BuildTarget buildTarget
{get{#if UNITY_ANDROIDreturn  BuildTarget.Android;#elif UNITY_WEBGLreturn BuildTarget.WebGL;#elif UNITY_STANDALONEreturn BuildTarget.StandaloneWindows;#endif}
}
private void OnEnable()
{int nBit = 0;if(defineArray.Length >= 32){Debug.LogError("警告位已经不够用了");}for(int i = 0; i < defineArray.Length; i++){if (string.IsNullOrEmpty(defineArray[i])) continue;if(EasyUseEditorFuns.HasDebugSymble(buildTarget,defineArray[i])){nBit |=  GetBit(nBit, i);}   }(target as Main).DefineBit = nBit;//c# read json }static int GetBit(int number, int bitPosition)
{// 检查位是否有效if (bitPosition < 0 || bitPosition >= sizeof(int) * 8){throw new ArgumentOutOfRangeException(nameof(bitPosition), "位位置无效");}// 生成掩码：将 1 左移 bitPosition 位，然后取反int mask = (1 << bitPosition);// 使用按位与操作干掉指定位return number | mask;
}
static int ClearBit(int number, int bitPosition)
{// 检查位是否有效if (bitPosition < 0 || bitPosition >= sizeof(int) * 8){throw new ArgumentOutOfRangeException(nameof(bitPosition), "位位置无效");}// 生成掩码：将 1 左移 bitPosition 位，然后取反int mask = ~(1 << bitPosition);// 使用按位与操作干掉指定位return number & mask;
}static bool HasBit(int number, int bitPosition)
{// 检查位是否有效if (bitPosition < 0 || bitPosition >= sizeof(int) * 8){throw new ArgumentOutOfRangeException(nameof(bitPosition), "位位置无效");}// 判断指定位是否为 1return (number & (1 << bitPosition)) != 0;
