資源管理導(dǎo)圖

資源管理.png

準(zhǔn)備工作

存儲等下需要加載的資源

• 設(shè)置Asset Labels（Unity右下角）
  • Cube ------ cubeprefab
  • mat ------- cubemat
  • pic ------- cubetexture

待會加載資源就是靠標(biāo)簽加載的

一鍵打包的實現(xiàn)

using UnityEngine;
using UnityEditor;
using System.IO;

public class BuildAssetBundle : Editor
{
    [MenuItem("AssetBundle/Build/Windows")]
    public static void BuildWindows()
    {
        //AssetBundle的存儲路徑
        string path = Application.dataPath + "/AssetBundle/Windows/";
        //如果路徑不存在
        if (!File.Exists(path))
        {
            //創(chuàng)建路徑
            Directory.CreateDirectory(path);
        }
        //打包
        BuildPipeline.BuildAssetBundles(path, BuildAssetBundleOptions.None, BuildTarget.StandaloneWindows64);
        //打印
        Debug.Log("打包成功");
    }
}

打包完成后刪掉"CubeAsset"文件夾（其實刪不刪無所謂誓琼，主要是確認(rèn)資源是從AssetBundle里面加載出來的）

AssetBundle文件夾的信息

加載紋理圖（無依賴關(guān)系）

using UnityEngine;
using System.Collections;
using UnityEngine.UI;

public class LoadTexture : MonoBehaviour
{
    private string path;
    public string bundleName;
    public string assetName;

    private void Awake()
    {
        path = "file://" +Application.dataPath + "/AssetBundle/Windows/";
    }

    private IEnumerator Start()
    {
        WWW www = new WWW(path + bundleName);
        //下載
        yield return www;
        //獲取AssetBundle
        AssetBundle ab = www.assetBundle;
        //加載資源
        Texture t = ab.LoadAsset(assetName) as Texture;
        //放圖片
        GetComponent<RawImage>().texture = t;
        //釋放資源
        ab.Unload(false);
    }
}

bundleName和assetNam根據(jù)一鍵打包的結(jié)果名稱和原圖片資源名稱決定
