一、asset序列化：
[CreateAssetMenu(fileName ="ABConfig",menuName ="CreateABConfig",order =0)]
public class ABConfig : ScriptableObject {
public List<string> m_AllPrefabsPath=new List<string>();
public List<FileDirABName> m_AllFileDirAB = new List<FileDirABName>();
[System.Serializable]
public struct FileDirABName
{
public string ABName;
public string Path;
}
}二、打包AB包：
[MenuItem("Tools/1.打包AB包",false,1)]
public static void BuildAB()
{
//EditorUserBuildSettings.activeBuildTarget检测运行所在平台
//将AB打包在StreamingAssets文件夹下,注意先创建该文件夹
BuildPipeline.BuildAssetBundles(Application.streamingAssetsPath, BuildAssetBundleOptions.ChunkBasedCompression,EditorUserBuildSettings.activeBuildTarget);
AssetDatabase.Refresh(); //编辑器的刷新
}三、编辑器查找和进度显示：
//查找到所有prefabs，转换成GUIID数组。
string[] allPrefabsGUIDArr = AssetDatabase.FindAssets("t:Prefab", abConfig.m_AllPrefabsPath.ToArray());
for (int i = 0; i < allPrefabsGUIDArr.Length; i++)
{
string path = AssetDatabase.GUIDToAssetPath(allPrefabsGUIDArr[i]);
Debug.Log(path);
EditorUtility.DisplayProgressBar("查找prefabs", "path：" + path, i * 1.0f / allPrefabsGUIDArr.Length);
}
EditorUtility.ClearProgressBar();四、代码设置AB包名：
static void SetABName(string name,string path)
{
AssetImporter assetImporter = AssetImporter.GetAtPath(path);
if (assetImporter==null)
{
Debug.LogError("不存在此路径的文件：" + path);
}
else
{
assetImporter.assetBundleName = name;
}
}五、代码清除Ab包名：
string[] oldABNameArr = AssetDatabase.GetAllAssetBundleNames();
for (int i = 0; i < oldABNameArr.Length; i++)
{
AssetDatabase.RemoveAssetBundleName(oldABNameArr[i],true);//是否强制清除
EditorUtility.DisplayProgressBar("清除AB包名", "Name：" + oldABNameArr[i], i * 1.0f / allPrefabsGUIDArr.Length);
}
EditorUtility.ClearProgressBar();六、简易单例
public class Singleton<T> where T:new()
{
private static T m_instance;
public static T Instance
{
get
{
if (m_instance==null)
{
m_instance = new T();
}
return m_instance;
}
}
}public class MonoSingleton<T> : MonoBehaviour where T : MonoSingleton<T>
{
private static T instance;
public static T Instance
{
get
{
if (instance == null)
{
instance = FindObjectOfType<T>();
if (instance == null)
{
//创建脚本立即执行Awake
instance = new GameObject("Singleton Of " + typeof(T)).AddComponent<T>();
}
else
{
instance.Init();
}
}
return instance;
}
}
private void Awake()
{
if (instance == null)
{
instance = this as T;
Init();
}
}
protected virtual void Init()
{
}
}七、移动端判断是否点在UGUI组件上
UGUI 提供了一个检测是否点击在UI上的方法 EventSystem.current.IsPointerOverGameObject(); 在EventSystem的标准输入Standalone Input Model下是正常的，但是在Touch Input Module输入模式下不正常(编辑器中正常,Android端不正常)
public static bool IsPointerOverGameObject()
{
PointerEventData eventData = new PointerEventData(UnityEngine.EventSystems.EventSystem.current);
eventData.pressPosition = Input.mousePosition;
eventData.position = Input.mousePosition;
List<RaycastResult> list = new List<RaycastResult>();
UnityEngine.EventSystems.EventSystem.current.RaycastAll(eventData, list);
return list.Count > 0;
}或者
#if UNITY_EDITOR
if (EventSystem.current.IsPointerOverGameObject())
{
}
#elif UNITY_IOS || UNITY_ANDROID
if (Input.touchCount>0&& EventSystem.current.IsPointerOverGameObject(Input.GetTouch(0).fingerId))
{
}
#endif八、默认unity 脚本模板修改
默认模板地址：D:\Program Files\Unity2017.3.1f\Editor\Data\Resources\ScriptTemplates\81-C# Script-NewBehaviourScript.cs
/****************************************************

作者：Edision
邮箱: 424054763@qq.com

*****************************************************/
using UnityEngine;
public class #SCRIPTNAME# : MonoBehaviour
{
}把下边脚本放到Plugins/Editor文件夹下
/****************************************************

using System;
using System.IO;
public class ScriptsInfoRecoder : UnityEditor.AssetModificationProcessor
{
private static void OnWillCreateAsset(string path)
{
path = path.Replace(".meta", "");
if (path.EndsWith(".cs"))
{
string str = File.ReadAllText(path);
str = str.Replace("#CreateAuthor#", Environment.UserName).Replace(
"#CreateTime#", string.Concat(DateTime.Now.Year, "/", DateTime.Now.Month, "/",
DateTime.Now.Day, " ", DateTime.Now.Hour, ":", DateTime.Now.Minute, ":", DateTime.Now.Second));
File.WriteAllText(path, str);
}
}
}创建一个Test脚本：

using UnityEngine;
public class Test : MonoBehaviour
{
}九、射线
private void Update()
{
if (Input.GetMouseButtonDown(0))
{
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
/*射线检测单个*/
//RaycastHit hitInfo;
//if (Physics.Raycast(ray, out hitInfo, 1 << 8))
//{
// if (hitInfo.collider != null)
// {
// Debug.Log(hitInfo.point);
// }
//}
/*射线检测多个*/
//RaycastHit[] hitInfoArr = Physics.RaycastAll(ray, 1000, 1 << 8);
//Debug.Log(hitInfoArr.Length);
Collider[] colliderArr = Physics.OverlapSphere(player.transform.position, 3, 1 << 8);
foreach (var item in colliderArr)
{
Debug.Log(item.name);
}
}
}十、值类型和引用类型最基本的区别
//值类型改变的是值
int a = 10;
int b = a;
a = 20;
Debug.Log(a);//a=20
Debug.Log(b);//,b=10
//引用类型改变的是地址
TestData testData1 = new TestData();
testData1.ID = 1001;
TestData testData2 = testData1;
testData2.ID = 1002;
Debug.Log(testData1.ID);//打印1002
Debug.Log(testData2.ID);//打印1002
//string特殊的引用类型，不会改变引用，其实是新创建而已，相当于又new了一次
string str1 = "str1";
string str2 = str1;
str2 = "str2";
Debug.Log(str1);//打印"str1"
Debug.Log(str2);//打印"str2"十一、粘包和拆包 解决
using System;
using System.Collections.Generic;
using System.IO;
/// <summary>
/// 关于编码的工具类
/// </summary>
public static class EncodeTool
{
#region 粘包拆包问题，封装一个有规定的数据包
/// <summary>

public static byte[] EncodePacket(byte[] value)
{
//内存流对象
using (MemoryStream ms = new MemoryStream())
{
using (BinaryWriter bw = new BinaryWriter(ms))
{
//先写入数据长度，再写入数据
bw.Write(value.Length);
bw.Write(value);
byte[] byteArr = new byte[(int)ms.Length];
//复制字节数组，内存中转移效率极高
Buffer.BlockCopy(ms.GetBuffer(), 0, byteArr, 0, (int)ms.Length);
return byteArr;
}
}
}
/// <summary>
/// 解析消息体：从缓存里取出一个一个完整的数据包
/// </summary>
/// <returns></returns>
public static byte[] DecodePacket(ref List<byte> dataCache)
{
//四个字节构成一个int长度，小于4，就不能构成一个完整的消息体
if (dataCache.Count < 4)
{
throw new Exception("数据长度不足4，不能构成一个消息体");
}
//内存流对象
using (MemoryStream ms = new MemoryStream(dataCache.ToArray()))
{
using (BinaryReader br = new BinaryReader(ms))
{
//先写入数据长度，再写入数据
int len = br.ReadInt32();
int dataRemainLength = (int)(ms.Length - ms.Position);
if (len > dataRemainLength)
{
throw new Exception("数据长度不够包头的约定长度，不能构成一个完整的消息");
}
byte[] data = br.ReadBytes(len);
//更新数据缓存
dataCache.Clear();
dataCache.AddRange(br.ReadBytes(dataRemainLength));
return data;
}
}
}
#endregion
}十二、Unity发布PC版exe安装包（不是生成exe和Data文件夹）
当项目开发完成以后，对于我们的开发人员来说，最后一步就是去打包，其中Unity打包出来的PC项目是两个文件，一个.exe文件，一个Data文件夹。如果想运行，必须两个一块才能正常运行。
Window提供了可以对这个生成安装程序的方法，但下面要给大家介绍的是一个非常快捷方便的办法。使用RAR的自解压。
如何使用winrar命令压缩文件夹，都可以在“WinRAR帮助文件”中找到。
public static void GenerateWinExe(BuildTarget target, string pathToBuiltProject)
｛
if (target != BuildTarget.StandaloneWindows)
｛
return;
｝
var rootFolder = Path.GetDirectoryName(pathToBuiltProject);
var fileName = Path.GetFileNameWithoutExtension(pathToBuiltProject);
var configFilePath = string.Format("｛0｝/｛1｝_sfx.txt", SFXConfigFolder, fileName);
var buildAsExe = File.Exists(configFilePath);
var exePath = Path.GetDirectoryName(rootFolder) + "/" + Path.GetFileName(rootFolder) + (buildAsExe ? ".exe" : ".rar");
FileUtil.DeleteFileOrDirectory(exePath);
var argList = ProcessHelper.CreateArgumentsContainer();
var regKeyPath = @"SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\WinRAR.exe";
string winrarPath = null;
try
｛
var regKey = Registry.LocalMachine.OpenSubKey(regKeyPath);
winrarPath = regKey.GetValue("").ToString();
regKey.Close();
｝
catch (Exception e)
｛
｝
if (string.IsNullOrEmpty(winrarPath))
｛
winrarPath = "WinRAR.exe";
｝
argList.Add(winrarPath);
argList.Add("a");
argList.Add("-r");
argList.Add("-ep1");
if (buildAsExe)
｛
argList.Add("-sfx");
argList.Add("-iicon" + string.Format("｛0｝/｛1｝.ico ", SFXConfigFolder, fileName));
argList.Add("-scuc");
argList.Add("-z" + configFilePath);
｝
argList.Add(exePath);
argList.Add(rootFolder + "/*.*");
var p = ProcessHelper.Start(ProcessHelper.CreateStartInfo());
ProcessHelper.WriteLine(p, ProcessHelper.CreateArguments(argList));
p.WaitForExit();
Debug.Log(p.StandardOutput.ReadToEnd());
｝1.通过注册表获取WinRAR的安装路径，如果没获取到，有可能安装的绿色版，可以在path里面配置路径，然后直接使用winrar.exe
2.添加自解压模块
3.添加图标Path=默认安装路径
SavePath
Setup=游戏名.exe
Shortcut=D, 游戏名.exe, , , 快捷方式名，
1.设置默认安装路径
2.记录安装路径，下次安装会直接找到这个路径
3.自解压之后自动运行游戏
4.在桌面创建快捷方式
图标得使用“转ICO.exe”之类的软件制作，否则不会在不同分辨率之下，有对应的图标。
十三、C#自带线程池刷新
private void Test()
{
System.Timers.Timer temp_Timer = new System.Timers.Timer(1000d);
temp_Timer.AutoReset=true;
temp_Timer.Elapsed += (object sender, System.Timers.ElapsedEventArgs e) =>
{
Debug.Log("***测试当前C#循环***");
};
temp_Timer.Start();
//temp_Timer.Stop();
}十四、根据名称递归查找子物体
private Transform FindChildInTransform(Transform parent, string child)
{
Transform childTF = parent.Find(child);
if (childTF != null)
{
return childTF;
}
for (int i = 0; i < parent.childCount; i++)
{
childTF = FindChildInTransform(parent.GetChild(i), child);
}
return null;
}十五、动画控制
using System;
using UnityEngine;
namespace LastZero
{
/// <summary>
/// 动画控制
/// </summary>
public static class AnimatorController
{
/// <summary>
/// 播放动画
/// </summary>
/// <param name="animator">animator</param>
/// <param name="aniName">动画名</param>
/// <param name="callback">回调</param>
/// <returns>时长</returns>
public static float Play(this Animator animator, string aniName, Action callback = null)
{
if (!animator.TryGetClip(aniName))
{
Debug.LogError("未找到该动画！");
return 0;
}
float lengh = animator.GetLengthByName(aniName);
if (callback == null)
return lengh;
CoroutinesController.DelayDo(() =>
{
callback?.Invoke();
}, lengh);
return lengh;
}
/// <summary>
/// 获取动画时长
/// </summary>
/// <param name="animator">animator</param>
/// <param name="name">名字</param>
/// <returns>时长</returns>
public static float GetLengthByName(this Animator animator, string name)
{
float length = 0;
AnimationClip[] clips = animator.runtimeAnimatorController.animationClips;
foreach (AnimationClip clip in clips)
{
if (clip.name.Equals(name))
{
length = clip.length;
break;
}
}
return length;
}
/// <summary>
/// Try--获取Clip
/// </summary>
/// <param name="animator">animator</param>
/// <param name="name">名字</param>
/// <returns></returns>
private static bool TryGetClip(this Animator animator, string name)
{
AnimationClip[] clips = animator.runtimeAnimatorController.animationClips;
foreach (AnimationClip clip in clips)
{
if (clip.name.Equals(name))
{
return true;
}
}
return false;
}
}

string constring = "server=localhost;user=root;pwd=;database=test;";
string file = Application.dataPath + "/backup.sql";
using (MySqlConnection conn = new MySqlConnection(constring))
{
using (MySqlCommand cmd = new MySqlCommand())
{
using (MySqlBackup mb = new MySqlBackup(cmd))
{
cmd.Connection = conn;
conn.Open();
mb.ImportFromFile(file);
conn.Close();
}
}
}
}
}这里要提醒一下:MySqlBackup.dll是依赖于MySql.Data.dll的 所以引用MySqlBackup.dll的同时也要引用MySql.Data.dll
20、Hook 键盘事件
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using System;
using System.Diagnostics;
using System.Runtime.InteropServices;
class InterceptKeys : MonoBehaviour
{
private const int WH_KEYBOARD_LL = 13;
private const int WM_KEYDOWN = 0x0100;
private static LowLevelKeyboardProc _proc = HookCallback;
private static IntPtr _hookID = IntPtr.Zero;
void Start()
{
_hookID = SetHook(_proc);
}
void OnApplicationQuit()
{
UnhookWindowsHookEx(_hookID);
}
private static IntPtr SetHook(LowLevelKeyboardProc proc)
{
using (Process curProcess = Process.GetCurrentProcess())
using (ProcessModule curModule = curProcess.MainModule)
{
return SetWindowsHookEx(WH_KEYBOARD_LL, proc,GetModuleHandle(curModule.ModuleName), 0);
}
}
private delegate IntPtr LowLevelKeyboardProc(int nCode, IntPtr wParam, IntPtr lParam);
private static IntPtr HookCallback(int nCode, IntPtr wParam, IntPtr lParam)
{
if (nCode >= 0 && wParam == (IntPtr)WM_KEYDOWN)
{
int vkCode = Marshal.ReadInt32(lParam);
UnityEngine.Debug.Log("Keydown:"+vkCode);
}
return CallNextHookEx(_hookID, nCode, wParam, lParam);
}
[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
private static extern IntPtr SetWindowsHookEx(int idHook,

[DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)]
private static extern IntPtr GetModuleHandle(string lpModuleName);
}21、Unity方便查看日志的插件Reporter
将开源的项目clone下来解压，拷贝Reporter到项目的第三方库。
22、数据的序列化
[Serializable]
public abstract class Msg { }using System;
using System.Collections.Generic;
using System.IO;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary;
using System.Text;
using System.Threading;
/// <summary>
/// 序列化
/// </summary>
/// <returns></returns>
public static byte[] Serialize<T>(T msg) where T : Msg
{
using (MemoryStream ms = new MemoryStream())
{
try
{
BinaryFormatter bf = new BinaryFormatter();
bf.Serialize(ms, msg);
ms.Seek(0, SeekOrigin.Begin);
return ms.ToArray();
}
catch (SerializationException e)
{
Error("Failed to serialize.Reason:{0}", e.Message);
throw;
}
}
}
/// <summary>
/// 反序列化
/// </summary>
/// <returns></returns>
public static T Deserialize<T>(byte[] bytes) where T : Msg
{
using (MemoryStream ms = new MemoryStream(bytes))
{
try
{
BinaryFormatter bf = new BinaryFormatter();
T msg = (T)bf.Deserialize(ms);
return msg;
}
catch (SerializationException e)
{
Error("Failed to serialize.Reason:{0}", e.Message);
throw;
}
}
}23、数据的压缩与解压
/// <summary>
/// 数据压缩
/// </summary>
public static byte[] Compress(byte[] input)
{
using (MemoryStream outMS = new MemoryStream())
{
using (GZipStream gzs = new GZipStream(outMS, CompressionMode.Compress, true))
{
gzs.Write(input, 0, input.Length);
gzs.Close();
return outMS.ToArray();
}
}
}
/// <summary>
/// 数据解压缩
/// </summary>
public static byte[] DeCompress(byte[] input)
{
using (MemoryStream inputMS = new MemoryStream(input))
{
using (MemoryStream outMS = new MemoryStream())
{
using (GZipStream gzs = new GZipStream(inputMS, CompressionMode.Decompress))
{
byte[] bytes = new byte[1024];
int len = 0;
while ((len=gzs.Read(bytes,0,bytes.Length))>0)
{
outMS.Write(bytes, 0, len);
}
gzs.Close();
return outMS.ToArray();
}
}
}
}24、C# String 前面不足位数补零的方法
比如 定义一个整型
int i = 5;
要把这个 i 转换成 0005，拼接到字符串中，可以使用方法
string s = i.ToString().PadLeft(4,'0'); //第一个参数是位数，第二个是位数不足时，补充的字符；
定义：
PadLeft(int totalWidth, char paddingChar) //在字符串左边用 paddingChar 补足 totalWidth 长度
PadRight(int totalWidth, char paddingChar) //在字符串右边用 paddingChar 补足 totalWidth 长度
注意第二个参数为 char 类型，所以用单引号，也可以用 Convert.ToChar(string value) 把字符串转换成 char 类型。如果字符串长度大于 1，则使用 str.ToCharArray()[index]。
查看其他人博客还有类似
1> i.ToString("D5");
2> i.ToString("0000")); //转换成4位
等方法，没有测试过。请用之前试试可行否；25、FPS显示
using UnityEngine;
using UnityEngine.UI;
public class FPSManager : MonoBehaviour
{
public Text fpsText;
float deltaTime;
public int targetFps = 30;
[Tooltip("ignore targetFPS when vSyncCount > 0")]
public int vSyncCount = 0;
float UpdateTextTimer = 0f;
float UpdateTextThreshold = 0.2f;
void Update()
{
#if !UNITY_WEBGL || UNITY_EDITOR
if (QualitySettings.vSyncCount != vSyncCount) QualitySettings.vSyncCount = vSyncCount;
if (Application.targetFrameRate != targetFps) Application.targetFrameRate = targetFps;
#endif
if (fpsText == null) return;
deltaTime += (Time.deltaTime - deltaTime) * 0.1f;
//if (Time.frameCount % 5 == 0)
//{
// float fps = 1.0f / deltaTime;
// fpsText.text = "FPS: " + Mathf.Ceil(fps).ToString();
//}
UpdateTextTimer += Time.deltaTime;
if (UpdateTextTimer > UpdateTextThreshold)
{
UpdateTextTimer = 0f;
float fps = 1.0f / deltaTime;
fpsText.text = "FPS: " + Mathf.Ceil(fps).ToString();
}
}
public void Action_SetFPS(int _fps)
{
targetFps = _fps;
}
