[游戏开发][Unity]Assetbundle加载篇（8）加载场景特殊处理_unity assetbundle加载场景

目录

打包与资源加载框架目录

前言

无论是AB模式还是编辑器模式，都可以加载不在BuildSetting目录里的场景

编辑器加载接口，可以根据场景路径加载：

UnityEditor.SceneManagement.EditorSceneManager.LoadSceneAsyncInPlayMode("Assets/Works/Res/" + _resPath, parameters);

 AB包加载接口，请注意，AB包加载的sceneName不带扩展名(.unity)

string sceneName = System.IO.Path.GetFileNameWithoutExtension(_resPath);
SceneManager.LoadSceneAsync(sceneName, parameters);

正文

ResourceManager获取SceneLoader的时候做个小改变，需要用户层传入 是Add还是Single

无论是AB包加载模式，还是Editor加载模式，要区分加载目标是资源是场景。

 编辑器加载代码：EditorLoadTask，重点看Tick方法里加载目标是Scene的代码

#if UNITY_EDITOR
 
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEditor;
using UnityEngine;
using UnityEngine.SceneManagement;
 
public class EditorLoadTask:LoadTaskBase
{
    /*
     * 使用方式:
     * "Works/Res/Prefabs/UIPanel/Canvas.prefab"
     * 要带着文件扩展名
     */
    public override void DoTask()
    {
        string path = "Assets/Works/Res/" + _loadResPath;
 
        if (_targetType != typeof(Scene))
            _target = AssetDatabase.LoadAssetAtPath(path, _targetType);
        //模拟异步下一帧加载
        _loadState = TaskLoadState.LoadingAsset;
    }
 
    public override void Tick()
    {
        if (_loadState != TaskLoadState.LoadingAsset)
            return;
        if (_targetType == typeof(Scene))
        {
            //EditorLoadTask 检查场景是否存在
            Scene scene = UnityEditor.SceneManagement.EditorSceneManager.GetSceneByPath("Assets/" + _loadResPath);
            if (scene == null) {
                _loadState = TaskLoadState.LoadAssetFailed;
                //通知ResourceLoader加载成功或失败
                _callback?.Invoke(null, false);
            }
            else
            {
                _loadState = TaskLoadState.LoadAssetSuccess;
                //通知ResourceLoader加载成功或失败
                _callback?.Invoke(null, true);
            }
        }
        else
        {
            _loadState = _target == null ? TaskLoadState.LoadAssetFailed : TaskLoadState.LoadAssetSuccess;
            if (_loadState == TaskLoadState.LoadAssetFailed)
                LogManager.LogError($"Failed to load asset object : path:{_loadResPath}, type:{_targetType.ToString()}");
            通知Loader加载结果
            _callback?.Invoke(_target, _target != null);
        }
    }
}
#endif

AB加载代码代码太长，在前面的文章里已经贴过源码了，这里就不再展示。
