AssetBundle打包：腳本放在Editor文件夾內
具體代碼如下：
C# Code
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 | using UnityEditor; using System.IO; public class CreateAssetBundles { [MenuItem("自定義菜單/資源打包")] static void BuildAllAssetBundles() { //定義文件夾名字 string dir = "AssetBundles"; //文件夾不存在，則創建 if(!Directory.Exists(dir)) { Directory.CreateDirectory(dir); } //資源打包 BuildPipeline.BuildAssetBundles(dir, BuildAssetBundleOptions.None, BuildTarget.StandaloneWindows64); } } |
AssetBundle的四種方式資源加載，腳本綁在場景任意物體即可
