Unity 会检查是否有可用的更新。在 Unity 启动时,或者选择 Help > Check for Updates 菜单项时,便会执行此检查。更新检查过程会将当前 Unity 修订号(在 About Unity 对话框中的版本名称后面的括号内显示的五位数字)发送到更新服务器,然后在此处与最新发布的版本进行比较。如果有更新版本的 Unity,则会显示以下对话框:
如果使用的版本是最新版本,则会显示以下对话框:
单击 Download new version 按钮将进入可下载新版本的网站。
来自服务器的响应中还包含一个时间间隔,建议何时应进行下一次更新检查。这样,当认为 Unity 没有可用的更新时,可以降低更新检查频率。
如果正在项目进行过程中,可能不希望更新为 Unity 的新版本。在 Unity Editor Update Check 对话框中选中 Skip this version 按钮将阻止 Unity 通知此更新。
无法禁用检查更新。对话框上的 Check For Updates 复选框用于控制 Unity 启动时是否发出有关更新(如果可用)的通知。即使取消选中 Check for Updates 选项,仍可以使用 Help > Check for Updates 菜单项来检查更新。
