AsssetBunlder打包

就想.net网站。很多图标都是放一个大图片上。而不是一个图标就是一个图片
因为是在项目编辑时候给资源打包。并不是项目运行。所以要用到Editor。untiy编辑类,脚本放到Editor文件夹中
1 using UnityEngine; 2 using System.Collections; 3 using UnityEditor; 4 public class AsssetBunlder 5 { 6 [MenuItem("Custom/SayHello")] 7 static void SayHello() 8 { 9 Debug.Log("hello"); 10 } 11 12 [MenuItem("Custom/CreateBundle")] 13 static void CreateBoundle() 14 { 15 /* 16 * Selection类,在编辑状态下,获取选中的对象引用 17 */ 18 Object[] objs = Selection.GetFiltered(typeof(object), SelectionMode.DeepAssets); 19 20 string path = string.Empty; 21 22 foreach (Object ojb in objs) 23 { 24 path = Application.streamingAssetsPath + "/" + ojb.name + ".unity3d"; 25 //创建AssetBunlder 26 BuildPipeline.BuildAssetBundle(ojb, null, path); 27 28 //BuildTarget.Android :不同平台打包路径不同 29 //BuildPipeline.BuildAssetBundle(ojb, null, path, BuildAssetBundleOptions.CollectDependencies, BuildTarget.Android); 30 } 31 //自动刷新 32 AssetDatabase.Refresh(); 33 } 34 35 36 37 [MenuItem("Custom/CreateAllBundle")] 38 static void CreateAllBoundle() 39 { 40 /* 41 * Selection类,在编辑状态下,获取选中的对象引用 42 */ 43 Object[] objs = Selection.GetFiltered(typeof(object), SelectionMode.DeepAssets); 44 45 string path = string.Empty; 46 path = Application.streamingAssetsPath + "/All.assetbundle"; 47 //创建AssetBunlder 48 BuildPipeline.BuildAssetBundle(null, objs, path); 49 50 //自动刷新 51 AssetDatabase.Refresh(); 52 } 53 54 55 //场景打包 56 [MenuItem("Custom/StreamBundle")] 57 static void StreamBundleScene() 58 { 59 //要压缩的场景位置 60 string[] leves = { "Assets/Scene/Demo2.unity" }; 61 62 //压缩后。资源保存的位置 63 string path = Application.streamingAssetsPath + @"/Test.assetsbundle"; 64 65 /* 66 BuildAdditionalStreamedScenes:以流的方式打包场景 67 * StandaloneWindows64:在window64位电脑下打包 68 */ 69 BuildPipeline.BuildPlayer(leves, path, BuildTarget.StandaloneWindows64, BuildOptions.BuildAdditionalStreamedScenes); 70 71 72 73 } 74 75 }
单击菜单。会出现你刚写的菜单选项
单击不同的选项就可以根据不同的资源打包了
当读取资源前必须解压

对于不同平台打包路径是不同的。具体看
