复制其他项目的资产

Assets used in one UNIGINE project, both simple and composite (e.g. a material requiring a texture, or a node that requires several materials linked to plenty of textures), can be easily copied to another project using Asset Packages.一个UNIGINE项目中使用的资产，无论是简单的还是复合的（例如，需要纹理的材料，或者需要与大量纹理相关联的多种材料的节点），都可以使用Asset Packages轻松地复制到另一个项目中。

Asset Package is a collection of files and data for UNIGINE projects stored in a single *.upackage file. Asset Package compresses data while preserving the original directory structure. Asset Packages can be used to conveniently transfer content between your projects or exchange data with other users, be it a single model or a scene with a set of objects driven by logic implemented via C# components.资产包是存储在单个*.upackage文件中的UNIGINE项目的文件和数据的集合。 Asset Package在保留原始目录结构的同时压缩数据。资产包可用于方便地在您的项目之间传输内容或与其他用户交换数据，无论是单个模型还是场景，场景中都有一组对象，这些对象由通过C＃组件。

To copy your assets from one project to another:要将您的资产从一个项目复制到另一个项目：

1. Open your source project in UnigineEditor and export all necessary assets as a package file.在UnigineEditor中打开您的源项目，然后将所有必要资产导出为打包文件。
2. Open your target project that requires those assets in UnigineEditor and import your package.在UnigineEditor中打开需要这些资产的目标项目，然后导入你的包裹。

6. In the dialog window that opens, define the name and path to your package and click Save. 在打开的对话框窗口中，定义包的名称和路径，然后单击Save。

As soon as your Asset Package is successfully created, the location of your *.upackage file will be shown in your file manager.成功创建资产包后，文件管理器中将显示*.upackage文件的位置。

To import contents of an existing package to your project you need to:要将现有软件包的内容导入到您的项目中，您需要：

1. Drag it from the File Explorer directly into the Asset Browser or click the Import button and select the *.upackage file. If you have already added the *.upackage file to your targed project, double-click on it.
   注意

   Do not use a file manager of your OS to copy a package to your project's folder, as in this case the package will be displayed in the Asset Browser, but its contents won't be extracted.Do not use a file manager of your OS to copy a package to your project's folder, as in this case the package will be displayed in the Asset Browser, but its contents won't be extracted.
   The following window will open:

   

   Do not use a file manager of your OS to copy a package to your project's folder, as in this case the package will be displayed in the Asset Browser, but its contents won't be extracted.将其从文件资源管理器直接拖到Asset Browser中，或单击Import按钮，然后选择*.upackage文件。如果您已经将*.upackage文件添加到目标项目中，请双击它。
   注意

   Do not use a file manager of your OS to copy a package to your project's folder, as in this case the package will be displayed in the Asset Browser, but its contents won't be extracted.请勿使用操作系统的文件管理器将软件包复制到项目的文件夹中，因为在这种情况下，软件包将显示在Asset Browser中，但不会提取其内容。
   将打开以下窗口：
