[游戏开发][Unity] ScriptableObject数据创建与各种加载方式

前言

ScriptableObject支持把类对象数据序列化成Unity asset文件，同时支持反序列化成类对象。本文章通过两个案例讲解ScriptableObject的使用方式，第一个是简单案例，序列化简单的bool值和Sting数据。第二个是复杂案例，在类对象里嵌套类对象并序列化成asset文件，再把它反序列化出来。

案例1

[CreateAssetMenu]

public class GameSetting : ScriptableObject

{

public static GameSetting Instance;

public bool AssetbundleMode;

public string GameName = "Story";

}

案例2

using System;

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

[Serializable]

public class TestData

{

public string Name;

public int index;

}

[CreateAssetMenu]

public class TestScriptableObject : ScriptableObject

{

public List dataList = new List();

}

正文

下面开始第一个案例，序列化数据如下

using UnityEngine;

[CreateAssetMenu]

public class GameSetting : ScriptableObject

{

public static GameSetting Instance;

public bool AssetbundleMode;

public string GameName = "Test!!!!!";

}

创建Unity Aseet文件的两种方式

创建方式1，通过菜单创建，文件会出现在Assets文件夹内

创建方式2，通过代码创建，可以设置创建路径，并设置数据

private void CreateGameSetting()

{

string path = "Assets/Works/Resource/AllGameSetting/GameSetting.asset";

GameSetting setting = ScriptableObject.CreateInstance();

setting.AssetbundleMode = true;

setting.GameName = "Test!!!!!";

AssetDatabase.CreateAsset(setting, path);

AssetDatabase.SaveAssets();

AssetDatabase.Refresh();

}

加载GameSetting.asset的三种方式

方式1：Resources加载

GameSetting setting = Resources.Load("GameSetting");

方式2：编辑器加载

private void EditorLoadGameSetting()

{

GameSetting setting = AssetDatabase.LoadAssetAtPath("Assets/Works/Resource/AllGameSetting/GameSetting.asset");

Debug.LogError(setting.AssetbundleMode);

FSMManager.Instance.Init();

}

方式3：assetbundle加载GameSetting

把这个GameSetting.asset文件打包成ab包

void LoadGameSettingFromBundle()

{

string loadPath = Application.streamingAssetsPath + "/assets/works/resource/allgamesetting/gamesetting.unity3d";

AssetBundle bundle = AssetBundle.LoadFromFile(loadPath);

//全路径加载也可以

//GameSetting.Instance = bundle.LoadAsset("assets/works/resource/allgamesetting/gamesetting.asset");

GameSetting.Instance = bundle.LoadAsset("GameSetting.asset");

Debug.LogError("GameName: " + GameSetting.Instance.GameName);

}

案例二

下面开始第二个复杂案例。

调用下面的代码都可以创建一个Unity Asset文件

private void GetBundleRelationFile()

{

string path = "Assets/Works/Resource/AllGameSetting/TestData.asset";

TestScriptableObject testData = ScriptableObject.CreateInstance();

AssetDatabase.CreateAsset(test, path);

AssetDatabase.SaveAssets();

AssetDatabase.Refresh();

}

再把这个Asset打包成ab

加载AB包并从反序列化数据

Resources加载方式和编辑器加载就不展示了，直接从ab包里反序列化数据

public void LoadBundleRelation()

{

string loadPath = Application.streamingAssetsPath + "/assets/works/resource/allgamesetting/testdata.unity3d";

AssetBundle bundle = AssetBundle.LoadFromFile(loadPath);

TestScriptableObject TestData = bundle.LoadAsset("TestData.asset");

Debug.LogError("TestScriptableObject.TestData.dataList[1].Name: " + TestData.dataList[1].Name);

Debug.LogError("TestScriptableObject.TestData.dataList[1].Index: " + TestData.dataList[1].index);

}
