Unity热更新方案C#Like(廿三)-实战:示范如何把Unity官方免费例子Tanks! Tutorial转成可热更新项目

C#Like是Unity的热更方案,使用纯C#语言写出可以热更新的代码,就像可以在所有平台使用DLL(动态链接库)文件一样.遵从KISS设计原则,让用户轻松构建或升级成Unity的热更新项目.

简介

本篇主要介绍如何一步一步地详细地把Unity官方免费例子Tanks! Tutorial转成可热更新项目.

搭建的详细步骤

我们首先选取一个最少代码的Unity出品的免费的例子"Tanks! Tutorial"作为示范,即官方Demo里的"TankFree"项目是如何制作的,下面是详细步骤:

• 创建一个空白的2D/3D项目为TankFree

• 到Unity资源商店购买相关的免费资源:

  如果已购买则跳过本步骤
  • 免费购买Tanks! Tutorial
  • 免费购买C#Like免费版

• 导入相关的免费资源:

  • 先打开Package Manager界面 : 菜单'Window'->'Package Manager'
  • 导入'Tanks! Tutorial' : 'Packages: My Assets'->'Tanks! Tutorial'->'Import'
  • 导入'C#Like免费版' : 'Packages: My Assets'->'C#LikeFree Hot Update Framework'->'Import'

• 移除默认导出C#Like内置资源的AssetBundle: 你也可以直接删掉它

  • Project面板选中"Assets\C#Like\Scenes\BuildInDemoScene"文件后, 在Inspector面板里的Asset Labels的AssetBundle设置为none
  • Project面板选中"Assets\C#Like\Sample"目录后, 在Inspector面板里的Asset Labels的AssetBundle设置为none

• 修改产品名称:

  • 菜单'Edit'->'Project Settings'->'Player'->'Product Name' 设置为 'Tank'

• 修改脚本:

  • 删除目录'\Assets\Scripts'. 因为热更脚本里的类不能使用和没有命名空间的类名取相同的名字, 例如非热更脚本里有个不带命名空间的类叫'ClassName',热更新脚本里不能存在命名空间不同但类名相同的类'NamespaceName.ClassName', 所以建议所有的类都加上命名空间吧.
  • 复制目录'\Assets\_Completed-Assets\Scripts' 到 '\Assets\_Completed-Assets\HotUpdateScripts'. 即我们将要把原来目录'\Assets\_Completed-Assets\Scripts'里的非热更脚本改成目录'\Assets\_Completed-Assets\HotUpdateScripts'里的热更新脚本
  • 最终改好后的脚本文件详见GitHub里的TankFree项目,下面简述一些注意的事项:
    • 把原命名空间'Complete'改为'CSharpLike'.这个纯粹看你个人爱好,没限定改成什么.
    • 把基类'MonoBehaviour'的都改为'LikeBehaviour'
    • 按需确定要采用不同的HotUpdateBehaviourXXXXX.详见'\Assets\C#Like\Runtime\Interaction\HotUpdateBehaviourCustom'
      • 例如'Assets\_Completed-Assets\HotUpdateScripts\Camera\CameraControl.cs'里面用到FixedUpdate, 所以我们采用HotUpdateBehaviourFixedUpdate来绑定预制体
      • 例如'Assets\_Completed-Assets\HotUpdateScripts\Shell\ShellExplosion.cs'里面用到OnTriggerEnter, 所以我们采用HotUpdateBehaviourTrigger来绑定预制体
      • 根据你的项目,强力建议你自行仿造地编写一些非热更新定制绑定脚本, 放入'\Assets\C#Like\Runtime\Interaction\HotUpdateBehaviourCustom'目录内, 可以参考'Assets\C#Like\Runtime\Interaction\HotUpdateBehaviourCustom\HotUpdateBehaviourAll.cs'来定制
      • 如果你的项目已上线且找不到合适的绑定,就使用HotUpdateBehaviourAll吧
    • 根据绑定不同需求,在Awake或Start里绑定预制体里的数据 (int/bool/double/float/string/Color/Vector3/GameObject/TextAsset/Material/Texture/AudioClip/Sprite)
    • 注意生命周期顺序 : Awake -> OnEnable -> Start. 如果绑定其他LikeBehaviour对象的数据,尽量放在Start函数而非Awake,因为在Awake的时候,其他对象尚未执行初始化
    • C#Like免费版不支持协程,需要用Update来代替,更多免费版和完整版的区别详见:主页
    • WebGL下,AudioClip不知为何会报错无法识别,最终使用'ResourceManager.LoadAudioClipAsync'来下载音频文件后绑上的. 奇怪,不知为何'Platformer Microgame'又没问题
  • 然后我们逐一地把修改目录'\Assets\_Completed-Assets\HotUpdateScripts'里的所有cs脚本文件:
    1. 我们复制'Assets/_Completed-Assets/Scripts'整个目录为'Assets/_Completed-Assets/HotUpdateScripts'目录, 里面包含8个脚本文件,里面的8个cs文件是待修改成热更新脚本, 和原代码改动部分会标注 '// RongRong : '
    2. 修改'Assets/_Completed-Assets/HotUpdateScripts/Camera/CameraControl.cs',以下是完整版和免费版对应的改后热更新代码:

This is a precaution in case of missing button events.  m_CurrentLaunchForce = m_MinLaunchForce;  }  }  
       }

    9. 修改'Assets/_Completed-Assets/HotUpdateScripts/Managers/UIDirectionControl.cs',以下是完整版和免费版对应的改后热更新代码(两者相同):

       using UnityEngine;  namespace CSharpLike// RongRong : 命名空间改为 "CSharpLike" 或者前面使用 "using CSharpLike;".  
       {  /// <summary>  /// RongRong : 本类包含函数 'Start/Update',  /// 我们使用 'HotUpdateBehaviourUpdate' 来绑定预制体, 设置 'scriptUpdateFPS' 数值为 10000.  /// 预制体设置 'Booleans' : "m_UseRelativeRotation".  /// </summary>  public class UIDirectionControl : LikeBehaviour // RongRong : 基类 'MonoBehaviour' 改为 'LikeBehaviour'  {  // This class is used to make sure world space UI  // elements such as the health bar face the correct direction.  public bool m_UseRelativeRotation = true;       // Use relative rotation should be used for this gameobject?  private Quaternion m_RelativeRotation;          // The local rotatation at the start of the scene.  // RongRong : 绑定数值必须在放在Awake函数内,因为执行顺序为 : Awake -> OnEnable -> Start.  void Awake()  {  // RongRong : 绑定预制体的数值  m_UseRelativeRotation = GetBoolean("m_UseRelativeRotation", true);  }  private void Start ()  {  m_RelativeRotation = transform.parent.localRotation;  }  private void Update ()  {  if (m_UseRelativeRotation)  transform.rotation = m_RelativeRotation;  }  }  
       }

• 修改预制体和场景:

  • 复制目录'\Assets\_Completed-Assets\Prefabs' 到 '\Assets\_Completed-Assets\HotUpdatePrefabs'. 即我们将要把原来目录'\Assets\_Completed-Assets\Prefabs'里的预制体改成目录'\Assets\_Completed-Assets\HotUpdatePrefabs'里的预制体
  • 最终改好后的预制体详见GitHub里的TankFree项目,下面简述一些差异:
    • 依次双击打开目录内的预制体,如果里面有绑定'\Assets\_Completed-Assets\Scripts'目录内的非热更新代码, 请在相同位置添加对应的HotUpdateBehaviourXXXXX组件,然后按需设置绑定参数
    • 删除被替换成热更新代码了的原组件.这步建议最后才移除, 因为可能预制体或场景之间存在互相引用的,暂时不移除可以方便查看引用
    • 注意预制体之间的引用尽量都在'\Assets\_Completed-Assets\HotUpdatePrefabs'内的预制体. 即目录'\Assets\_Completed-Assets\Prefabs'被删掉也不应该受影响
    • 里面的AudioClip组件的引用都设为None,因为我们这里都通过'ResourceManager.LoadAudioClipAsync'下载绑定了
  • 然后我们逐一地把目录'\Assets\_Completed-Assets\HotUpdateScripts'里的预制体进行修改:
    1. 我们复制'Assets/_Completed-Assets/Prefabs'整个目录为'Assets/_Completed-Assets/HotUpdatePrefabs'目录
    2. 编辑器内双击打开场景'Assets/_Complete-Game.unity',菜单'File'->'Save As...'另存为'Assets/_Complete-Game_HotUpdate.unity'
    3. 修改场景'Assets/_Complete-Game_HotUpdate.unity'.
       • 修改GameManager节点:移除原GameManager组件,新增HotUpdateBehaviour组件 (C#Like免费版的是HotUpdateBehaviourUpdate组件,'Script Update FPS'设置为9999), (WebGL平台的,把'Audio Source'组件的AudioClip设置为None)

         ​

       • 修改CameraRig节点:移除原CameraControl组件,新增HotUpdateBehaviourFixedUpdate组件

         ​

       • WebGL平台下,修改'CameraRig/Main Camera'节点:去掉'Post-process Layer'组件的勾. (WebGL下,不知为何勾上后就是各种报错,所以禁用该组件)
    4. 修改预制体'Assets/_Completed-Assets/HotUpdatePrefabs/CompleteShell.prefab': 移除原ShellExplosion组件,新增HotUpdateBehaviourTrigger组件. (WebGL平台的,修改'CompleteShell/CompleteShellExplosion'节点里的'Audio Source'组件的AudioClip设置为None)

       ​

    5. 修改预制体'Assets/_Completed-Assets/HotUpdatePrefabs/CompleteTank.prefab'
       • 移除原TankHealth组件,新增HotUpdateBehaviour组件,如下图设置:

         ​

       • 移除原TankShooting组件,新增HotUpdateBehaviourUpdate组件,如下图设置:

         ​

       • 移除原TankMovement组件,新增HotUpdateBehaviourCommon组件,如下图设置:

         ​

       • 'CompleteTank/Canvas/HealthSlider'节点,移除原UIDirectionControl组件,新增HotUpdateBehaviourUpdate组件,如下图设置:

         ​

       • (WebGL平台的,'Audio Source'组件的AudioClip设置为None)
    6. 修改预制体'Assets/_Completed-Assets/HotUpdatePrefabs/CompleteTankExplosion.prefab', (WebGL平台的,'Audio Source'组件的AudioClip设置为None)
    7. 设置AssetBundle名字和后缀,编辑器的Project面板选中'Assets/_Complete-Game_HotUpdate.unity', 在Inspector面板的'Asset Labels'设置AssetBundle:名字为'tanks',后缀为'ab',如下图设置:

       ​

    8. 这个时候直接点编辑器里点'▶'运行,应该可以正常调试运行的

• 配置裁剪'Assets/C#Like/link.xml'

  -C#Like(Free)导出脚本的时候会自动识别用到代码部分用到的UnityEngine模块生成到'link.xml';
  -C#Like(Free)导出AssetBundle的时候会自动识别部分用到的UnityEngine模块生成到'link.xml';
  -没有识别到的部分,需要你自行添加到'Assets/C#Like/Editor/customUsingModule.txt',如下
  1. UnityEngine.InputLegacyModule  
  2. Unity.Postprocessing.Runtime  
  3. com.unity.multiplayer-hlapi.Runtime  

• 修改C#Like配置: 菜单'Window'->'C#Like'->打开'C#Like Setting'面板

  最终的配置如图:

  ​

  • 'Hot Update Script Folder'设置为'Assets/_Completed-Assets/HotUpdateScripts' (可以拖放目录)
  • 'Product Name'设置为'Tank'
  • 'Display Name'设置为'Tanks! Tutorial'
  • 'Default Scene'设置为'Assets/_Complete-Game_HotUpdate.unity' (可以拖放文件)
  • 'Download Path'设置为'https://www.csharplike.com/CSharpLikeFreeDemo/AssetBundles'
  • 'New JSON Key'可以设置自定义JSON字符串. 例如键'Icon'对应值'ABC'

• 编辑器测试调试

  • 如需Visual Studio断点调试代码, 菜单"Window"->"C#Like"->"C#Like Setting"->勾上"is debug mode" 来开启调试模式.
  • C#Like完整版因为比免费支持更多C#特性,更加接近调试模式. 即免费版会出现更多调试模式下没问题但非调试模式下有问题的情况.
  • 在编辑器里点'▶'按钮就可以正常运行调试可热更新的场景了.
  • 为了方便测试,我们加了一个"Exit"按钮,用于退出当前游戏返回最初始的场景.

• 导出最终产品AssetBundle

  • 菜单"Window"->"C#Like"->"C#Like Setting"->点击按钮"Rebuild Scripts"
  • 最终生成目录"TankFree\AssetBundles\Tank",同时也会复制到目录"StreamingAssets"
    • "TankFree\AssetBundles\Tank\WebGL\code.ab" : 是包含二进制代码文件的AssetBundle
    • "TankFree\AssetBundles\Tank\WebGL\tanks.ab" : 是包含资源(场景)的AssetBundle
    • "TankFree\AssetBundles\Tank\WebGL\config.json" : 是ResourceManager用到的配置JSON文件,作用类似manifest文件
