Unity之資源打包之AssetBundle

Unity之資源打包之AssetBundle

1.打包資源

using UnityEngine;
using System.Collections;
using UnityEditor;
public class AssetsBundle
{
    /// <summary>
    /// 打包資源
    /// </summary>
    public void BundleAssets()
    {
        //創建資源包數組,裏面只能存一個資源包
        AssetBundleBuild[] assetBundleBuild = new AssetBundleBuild[1];
        //資源包命名
        assetBundleBuild[0].assetBundleName = "cube.assetbundle";
        //資源路徑
        assetBundleBuild[0].assetNames = new string[] { "Assets/Resources/Cube.prefab" };
        //打包
        BuildPipeline.BuildAssetBundles(Application.persistentDataPath, assetBundleBuild,BuildAssetBundleOptions.None, BuildTarget.StandaloneWindows);
    }
}

2.創建菜單

using UnityEditor;

class OperateMenu
{
    [MenuItem("Tools/BundleAssets")]
    public static void Bundle()
    {
        AssetsBundle assetsBundle = new AssetsBundle();
        assetsBundle.BundleAssets();
    }
}

3.加載打包資源

using System.IO;
using UnityEngine;

/// <summary>
/// 加載打包資源
/// </summary>
class LoadBundleAssets : MonoBehaviour
{
    private void Start()
    {
        byte[] buffer = GetBuffer();
        //從流中加載出資源包
        AssetBundle assetBundle = AssetBundle.LoadFromMemory(buffer);
        GameObject cube = assetBundle.LoadAsset<GameObject>("Cube");
        Instantiate(cube, Vector3.zero, cube.transform.rotation);
    }

    /// <summary>
    /// 獲取打包資源
    /// </summary>
    /// <returns></returns>
    private byte[] GetBuffer()
    {
        //讀取資源包文件,並寫入字符流
        FileStream fs = new FileStream(Application.persistentDataPath + "/cube.assetbundle",FileMode.Open);
        byte[] buffer = null;
        buffer = new byte[fs.Length];
        fs.Read(buffer, 0, buffer.Length);
        return buffer;
    }
}
