Screen.lockCursor 锁定光标
static var lockCursor : bool
Description描述
Should the cursor be locked?
是否光标被锁定？
The cursor will automatically be hidden, centered on view and made to never leave the view.
光标将自动隐藏，居中于视图并且不会离开这个视图。
In the web player the cursor may only only be locked after the user has clicked on the content and the user has not left the content view with the cursor. After the user presses escape or switches to another application the cursor will be automatically unlocked. The cursor lock will also be lost when exiting full screen mode. You can query if the cursor is currently locked by checking the lockCursor state. To provide a good user experience it is recommended to only lock the cursor as a result of pressing a button. Also you should check if the cursor got unlocked, in order to e.g. pause the game or bring up a game menu. In the Web Player and Editor the cursor will automatically be unlocked when you press escape. In the Standalone Player you have full control over mouse locking thus it won't automatically lose mouse lock unless you switch applications.
在网络播放器中光标仅在用户点击内容并且用户光标没有离开内容视图时锁定。在用户按下Esc键或切换到其他应用程序之后，光标将被自动解锁。当推出全屏模式时，光标锁定也将丢失。当前光标是否被锁定，你可以通过lockCursor查询状态。为了提供一个良好的用户体验，建议只在用户按下按钮的时候锁定光标。你也应该检查光标是否解锁，例如暂停游戏或打开一个游戏菜单。在网络播放器和编辑器，当你按下Esc时，光标将自动被解锁。在独立游戏模式中，您拥有完全控制鼠标锁定，因此，它不会自动失去鼠标锁定，除非你切换应用程序。
