            BuildAssetBundleOptions.CollectDependencies 包含所有依赖关系，应该是将这个物体或组件所使用的其他资源一并打包

            BuildAssetBundleOptions.CompleteAssets 强制包括整个资源。例如，如果传递网格到BuildPipeline.BuildAssetBundle函数并使用CompleteAssets，它还将包括游戏物体和任意动画剪辑，在同样的资源。
                                                   应该是，下载一部分，其余一并下载

            BuildAssetBundleOptions.DisableWriteTypeTree 禁用写入类型树，在资源包不包含类型信息。指定这个标识将使资源包易被脚本或Unity版本改变，但会使文件更小，更快一点加载。这个标识只影响默认包含的类型信息的平台资源包。

            BuildAssetBundleOptions.DeterministicAssetBundle 确定资源包，编译资源包使用一个哈希表储存对象ID在资源包中。
                                                             这使您可以重建的资产包，并直接引用资源。当重建资源包对象，在重建之后保证有相同的ID。由于它是一个32位的哈希表空间，如果在资源包有许多对象，这将增加潜在哈希表冲突。
                                                             Unity将给出一个错误，而不在这种情况下编译。哈希表是基于资源的GUID和对象的自身ID。
                                                             DeterministicAssetBundle加载被标准资源包慢，这是因为线程后台加载API通常期望对象排序的方式，这会使读取加少寻址。
