You can update an Asset Store package by using the Package Manager window.
Open the Package Manager window and select My Assets from the Packages menu.
An upward-pointing arrow indicator () appears next to any Asset Store packages that have updates available.
Optional: To view your list with the most recently updated Asset Store packages first, sort the list by Recently updated.
Select the Releases tab to review the changes in the latest versions of the package.
Click the Update button. Note: If the downloaded version of your package isn’t compatible with your version of the Unity Editor, a message appears in the details view and an alternate Update button displays, which lets you download a compatible version of the package.
进度条结束后,新 Asset Store 资源包的版本信息将显示在详细信息视图中,并且该包将立即可用。
