Unity 的 Package Manager

A package is a container that stores various types of features or assets, such as:

• Editor 工具和庫(kù)，例如文本編輯器、動(dòng)畫查看器或測(cè)試框架。
• 運(yùn)行時(shí)工具和庫(kù)，例如物理 API 或圖形管線。
• 資源集合，如紋理或動(dòng)畫。
• 項(xiàng)目模板，用于與其他人共享常見(jiàn)的項(xiàng)目類型。

包通過(guò) Package Manager 為 Unity 提供了廣泛的增強(qiáng)功能。在 Editor 中，可以通過(guò)以下菜單來(lái)訪問(wèn) Package Manager 窗口：Window > Package Manager。

Note: The Package Manager also supports viewing any Asset Store packages you have already downloaded or imported from the Unity Asset Store. For more information, see Asset packages.

Unity 如何使用包

When Unity opens a Project, the Unity Package Manager reads the Project manifest (1) to figure out what packages to load in the Project. Then it sends a request (2) to the package registry server (3) for each package that appears as a dependency in the manifest. The package registry then sends the requested information and data back to the Package Manager (4), which then installs those packages (5) in the Project. Each Project has its own manifest which lists the packages to load as “dependencies” of the Project.

Unity Package Manager 安裝包的方式

如果要在項(xiàng)目中包含某個(gè)包，則必須更新項(xiàng)目清單以將該包包含在依賴項(xiàng)列表中。如果需要，可以直接修改項(xiàng)目清單，但是讓 Package Manager 執(zhí)行此操作會(huì)更安全、更輕松。有關(guān)使用用戶界面的更多信息，請(qǐng)參閱 Package Manager 窗口的文檔。

如何使用 Package Manager

Package Manager 使用三個(gè)界面與用戶、清單和注冊(cè)表進(jìn)行通信：
