unity 怎么往生成的cs工程里面添加assets

创建AssetBundle
1创建一个空的Prefab，命名Cube，然后创建一个Cube，将其拉到刚创建好的Prefab
2新建一个脚本ExportAssetBundlescs（代码来自官方文档）,保存在Asset/Editor目录下
[csharp] view plaincopyprint
//在Unity编辑器中添加菜单
[MenuItem("Assets/Build AssetBundle From Selection")]
static void ExportResourceRGB2()
{
// 打开保存面板，获得用户选择的路径
string path = EditorUtilitySaveFilePanel("Save Resource", "", "New Resource", "assetbundle");
if (pathLength != 0)
{
// 选择的要保存的对象
Object[] selection = SelectionGetFiltered(typeof(Object), SelectionModeDeepAssets);
//打包
BuildPipelineBuildAssetBundle(SelectionactiveObject, selection, path, BuildAssetBundleOptionsCollectDependencies | BuildAssetBundleOptionsCompleteAssets, BuildTargetStandaloneWindows);
}
}
这时我们将看到Asset下面出现Build AssetBundle From Selection和Build Scene
3选中预设Cube，运行Build AssetBundle From Selection。这时会d出一个保存框，将其命名为cubeunity3d（这里为了测试方便，放在c盘。实际项目中，我们是需要将他们放在web服务器，供所有客户端下载更新)
4新建一个场景scene1unity,上面放置几个模型，然后保存
5选中该场景，在之前的ExportAssetBundlescs脚本中添加打包场景的函数，运行Assets->Build Scene，保存为scene1unity3d（这里为了测试方便，也放在c盘)
[csharp] view plaincopyprint
[MenuItem("Assets/Save Scene")]
static void ExportScene()
{
// 打开保存面板，获得用户选择的路径
string path = EditorUtilitySaveFilePanel("Save Resource", "", "New Resource", "unity3d");
if (pathLength != 0)
{
// 选择的要保存的对象
Object[] selection = SelectionGetFiltered(typeof(Object), SelectionModeDeepAssets);
string[] scenes = {"Assets/scene1unity"};
//打包
BuildPipelineBuildPlayer(scenes,path,BuildTargetStandaloneWindows,BuildOptionsBuildAdditionalStreamedScenes);
}
}
注意事项
aAssetBundle的保存后缀名可以是assetbundle或者unity3d
bBuildAssetBundle要根据不同的平台单独打包，BuildTarget参数指定平台，如果不指定，默认的webplayer
加载AssetBundle
我们通过一个简单的代码来演示如何加载assetbundle，包括加载普通asset和场景。
[csharp] view plaincopyprint
using System;
using UnityEngine;
using SystemCollections;
public class Load: MonoBehaviour
{
private string BundleURL = "file:///C:/cubeassetbundle";
private string SceneURL = "file:///C:/scene1unity3d";
void Start()
{
//BundleURL = "file//"+ApplicationdataPath+"/cubeassetbundle";
DebugLog(BundleURL);
StartCoroutine(DownloadAssetAndScene());
}
IEnumerator DownloadAssetAndScene()
{
//下载assetbundle，加载Cube
