fgui的ui管理框架_ET框架FGUIxasset的梦幻联动
前言
技能系統(tǒng)暫時告一段落，現(xiàn)在要花點時間規(guī)范一下客戶端這邊的資源管理以及一些流程優(yōu)化，這里選擇輕量高效資源管理框架xasset：xasset開源地址?github.com
版本為：https://github.com/xasset/xasset/commit/3d4983cd24ff92a63156c8078caf34b20d2d4c02?github.com
代碼量很少，一天就能看個差不多，但是質(zhì)量很高，如果只追求使用的話，是可以開箱即用的。
另外我對xasset底層源碼做了一些修改，主要是為了迎合我們ET傳統(tǒng)藝能await/async樣式代碼，所以推薦大家直接使用我項目(下文的Moba項目)中的xasset源碼
想要入門此資源管理框架的可以查看：xasset入門指南 - TA養(yǎng)成記?www.lfzxb.top
以及視頻教程：xasset4.0入門指南_嗶哩嗶哩 (゜-゜)つロ 干杯~-bilibili?www.bilibili.com
為了方便大家參考，可以去我對Moba項目：煙雨迷離半世殤/NKGMobaBasedOnET?gitee.com
，來查看更加具體的接入代碼，目前全部功能測試通過(資源加載，普通熱更新，VFS熱更新，FGUI適配)
流程預(yù)演
為了流暢接入一個框架，可以先把大體流程先構(gòu)思一下
xasset使用主要分為3塊打包工具配置(直接拿過來改幾個路徑即可使用(因為要打包到我們資源服務(wù)器指定的目錄下面))
本地資源服務(wù)器(使用ET自帶的Web資源服務(wù)器即可)
運行時類庫(非常簡單的接口使用，完全不需要關(guān)心資源管理)
打包工具
xasset打包流程分ApplyRule(配置打包規(guī)則)，BuildRule(自動分析依賴關(guān)系，優(yōu)化資源冗余，解決資源沖突)，BuildBundle(出包)三步走，具體內(nèi)容可參照上文鏈接
本地資源服務(wù)器
這一塊是ET的內(nèi)容，事實上我們只需要修改代碼，把資源打到文件資源服務(wù)器指定的目錄就行了
運行時類庫
xasset運行時接入相對于前面兩塊內(nèi)容較為復(fù)雜，主要包括資源熱更新模塊接入，API封裝，FGUI資源加載適配
正式開始
xasset導(dǎo)入
首先導(dǎo)入xasset到ET，主要有Editor和Runtime這兩部分內(nèi)容
首先是Editor部分，把Assets/XAsset/Editor文件夾放到我們ET中的Editor文件夾
Assets/XAsset/Runtime文件夾放到我們ET中的ThirdParty，注意移除UI文件夾，因為他是和xasset的官方Demo耦合的
會有一些Updater腳本的報錯，但是不要怕，我們接下來解決他
它里面的報錯主要是引用的Message Mono類(一個用于顯示對話框的類)找不到導(dǎo)致的，所以我們把這部分內(nèi)容改成用Debug輸出或者直接刪掉就行了
這里提供一個我的修改版本的

最后因為我們Model層會用到xasset，所以引用asmdef文件,Hotfix同理
替換ET資源管理模塊
因為我們使用xasset全盤托管資源管理(資源加載，熱更新)，所以我們只需要對其進(jìn)行封裝即可
移除所有打包模塊
Editor下的打包模塊相關(guān)代碼都可以刪除
ResourceComponent
支持await/async語法
using libx;
using UnityEngine;
namespace ETModel
{
public class ResourcesComponent: Component
{
#region Assets
/// /// 加載資源，path需要是全路徑 /// /// /// /// public T LoadAsset(string path) where T : UnityEngine.Object
{
AssetRequest assetRequest = Assets.LoadAsset(path, typeof (T));
return (T) assetRequest.asset;
}
/// /// 異步加載資源，path需要是全路徑 /// /// /// /// public ETTask LoadAssetAsync(string path) where T : UnityEngine.Object
{
ETTaskCompletionSource tcs = new ETTaskCompletionSource();
AssetRequest assetRequest = Assets.LoadAssetAsync(path, typeof (T));
//如果已經(jīng)加載完成則直接返回結(jié)果(適用于編輯器模式下的異步寫法和重復(fù)加載) if (assetRequest.isDone)
{
tcs.SetResult((T) assetRequest.asset);
return tcs.Task;
}
//+=委托鏈，否則會導(dǎo)致前面完成委托被覆蓋 assetRequest.completed += (arq) => { tcs.SetResult((T) arq.asset); };
return tcs.Task;
}
/// /// 卸載資源，path需要是全路徑 /// /// public void UnLoadAsset(string path)
{
Assets.UnloadAsset(path);
}
#endregion
#region Scenes
/// /// 加載場景，path需要是全路徑 /// /// /// public ETTask LoadSceneAsync(string path)
{
ETTaskCompletionSource tcs = new ETTaskCompletionSource();
SceneAssetRequest sceneAssetRequest = Assets.LoadSceneAsync(path, false);
sceneAssetRequest.completed = (arq) =>
{
tcs.SetResult(sceneAssetRequest);
};
return tcs.Task;
}
/// /// 卸載場景，path需要是全路徑 /// /// public void UnLoadScene(string path)
{
Assets.UnloadScene(path);
}
#endregion }
}
BundleDownloaderComponent
using System;
using System.Collections.Generic;
using System.IO;
using System.Threading.Tasks;
using libx;
using UnityEngine;
namespace ETModel
{
[ObjectSystem]
public class UiBundleDownloaderComponentAwakeSystem: AwakeSystem
{
public override void Awake(BundleDownloaderComponent self)
{
self.Updater = GameObject.FindObjectOfType();
}
}
[ObjectSystem]
public class UiBundleDownloaderComponentSystem: UpdateSystem
{
public override void Update(BundleDownloaderComponent self)
{
if (self.Updater.Step == Step.Completed)
{
self.Tcs.SetResult();
}
}
}
/// /// 封裝XAsset Updater /// public class BundleDownloaderComponent: Component
{
public Updater Updater;
public ETTaskCompletionSource Tcs;
public ETTask StartUpdate()
{
Tcs = new ETTaskCompletionSource();
Updater.ResPreparedCompleted = () =>
{
Tcs.SetResult();
};
Updater.StartUpdate();
return Tcs.Task;
}
}
}
ABPathUtilities
因為xasset使用全路徑對資源進(jìn)行加載，所以我們要提供路徑拓展

namespace ETModel
{
/// /// AB實用函數(shù)集，主要是路徑拼接 /// public class ABPathUtilities
{
public static string GetTexturePath(string fileName)
{
return $"Assets/Bundles/Altas/{fileName}.prefab";
}
public static string GetFGUIDesPath(string fileName)

return $"Assets/Bundles/Unit/{fileName}.prefab";
}
public static string GetScenePath(string fileName)
{
return $"Assets/Scenes/{fileName}.unity";
}
}
}
打包配置
BuildlScript
把腳本中對應(yīng)路徑進(jìn)行修改即可
public static class BuildScript
{
//打包AB的輸出路徑 public static string ABOutPutPath = c_RelativeDirPrefix + GetPlatformName();
//前綴 private const string c_RelativeDirPrefix = "../Release/";
//Rules.asset保存路徑 private const string c_RulesDir = "Assets/Res/XAsset/Rules.asset";
....
}
Assets
按需求修改Manifest保存路徑即可
public sealed class Assets: MonoBehaviour
{
public static readonly string ManifestAsset = "Assets/Res/XAsset/Manifest.asset";
...
}
適配FGUI
我們使用FGUI提供的自定義Package加載方式
using System;
using System.Collections.Generic;
using System.Threading.Tasks;
using FairyGUI;
using libx;
using UnityEngine;
namespace ETModel
{
/// /// 管理所有UI Package /// public class FUIPackageComponent: Component
{
public const string FUI_PACKAGE_DIR = "Assets/Bundles/FUI";
private readonly Dictionary packages = new Dictionary();
public void AddPackage(string type)
{
if (this.packages.ContainsKey(type)) return;
UIPackage uiPackage;
if (Define.ResModeIsEditor)
{
uiPackage = UIPackage.AddPackage($"{FUI_PACKAGE_DIR}/{type}");
}
else
{
ResourcesComponent resourcesComponent = Game.Scene.GetComponent();
uiPackage = UIPackage.AddPackage($"{FUI_PACKAGE_DIR}/{type}", (string name, string extension, Type type1, out DestroyMethod method) =>
{
method = DestroyMethod.Unload;
switch (extension)
{
case ".bytes":
{
var req = resourcesComponent.LoadAsset($"{name}{extension}");
return req;
}
case ".png"://如果FGUI導(dǎo)出時沒有選擇分離通明通道，會因為加載不到!a結(jié)尾的Asset而報錯，但是不影響運行 {
var req = resourcesComponent.LoadAsset($"{name}{extension}");
return req;
}
}
return null;
});
}
packages.Add(type, uiPackage);
}
public void RemovePackage(string type)
{
UIPackage package;
if (packages.TryGetValue(type, out package))
{
var p = UIPackage.GetByName(package.name);
if (p != null)
{
UIPackage.RemovePackage(package.name);
}
packages.Remove(package.name);
}
if (!Define.ResModeIsEditor)
{
Game.Scene.GetComponent().UnLoadAsset(ABPathUtilities.GetFGUIDesPath($"{type}_fui"));
Game.Scene.GetComponent().UnLoadAsset(ABPathUtilities.GetFGUIResPath($"{type}_atlas0"));
}
}
}
}
熱更新流程演示
打包
xasset出包流程為Apply Rule
Build Rule
Build Bundle
Build Player
根據(jù)我們ET的傳統(tǒng)藝能，資源形式大多都是一個個prefab(但是這種做法不提倡嗷，要按正規(guī)項目那樣分布)
這里以Unit為例，對Unit文件夾應(yīng)用Prefab規(guī)則(各個規(guī)則代表的含義可以去前面鏈接里的文章查看)
對于FUI(我們的FGUI編輯器導(dǎo)出的文件)需要應(yīng)用兩次規(guī)則，因為有png和bytes兩種文件
然后我們會得到一個如下所示的Rule.asset文件
其中的Scene In Build選項中需要包含我們隨包發(fā)布的Scene(ET中的Init.scene)
然后我們Build Bundle，就可以出包了
運行
為Global添加Update Mono腳本
其中各個內(nèi)容含義為：Step：當(dāng)前熱更新階段
Update Progess：當(dāng)前熱更新階段進(jìn)度
Development Mode：是否開啟編輯器資源模式，如果開啟會使用AssetDatabase.load進(jìn)行資源加載原始資源，如果關(guān)閉會模擬出包環(huán)境下的資源加載
Enable VFS：是否開啟VFS(對于VFS更加詳細(xì)的內(nèi)容，可以去上文鏈接中查看)
Base URL：資源下載地址，這里我填寫的是HFS的資源地址，如果我們使用ET資源文件服務(wù)器就是http://127.0.0.1:8080/
然后在腳本調(diào)用，即可進(jìn)行熱更新，其中對于熱更新各個階段的進(jìn)度，都可對Updater的Step和UpdateProgress來取得
await bundleDownloaderComponent.StartUpdate();
資源加載
同步資源加載
以我們加載Hotfix.dll.bytes為例
GameObject code = Game.Scene.GetComponent().LoadAsset(ABPathUtilities.GetNormalConfigPath("Code"));
byte[] assBytes = code.GetTargetObjectFromRC("Hotfix.dll").bytes;
byte[] pdbBytes = code.GetTargetObjectFromRC("Hotfix.pdb").bytes;
異步資源加載
這里加載一在路徑Assets/Textures/TargetTextureName.png中的貼圖示例
await Game.Scene.GetComponent().LoadAssetAsync("Assets/Textures/TargetTextureName.png");
資源卸載
Game.Scene.GetComponent().UnLoadAsset("Assets/Textures/TargetTextureName.png");
資源內(nèi)存釋放
xasset采用惰性GC的資源內(nèi)存管理方案，老版本是每幀都會檢查和清理未使用的資源(稱為靈敏GC)，這個版本底層只會在切換場景或者主動調(diào)用Assets.RemoveUnusedAssets();的時候才會清理未使用的資源，這樣用戶可以按需調(diào)整資源回收的頻率，在沒有內(nèi)存壓力的時候，不回收可以獲得更好的性能。
總結(jié)
以上是生活随笔為你收集整理的fgui的ui管理框架_ET框架FGUIxasset的梦幻联动的全部內(nèi)容，希望文章能夠幫你解決所遇到的問題。
