Cursor.lockState

Descripción

How should the cursor be handled?

When locked, the cursor will automatically be centered on view and made to never leave the view. The cursor will be invisible in this state, regardless of the value of Cursor.visible. Changing thet lockState to a different value will then make Cursor.visible control visibility again. When confined, the cursor behave normally with the exception of being confined to the view.

To provide a good user experience it is recommended to only lock or confine the cursor as a result of pressing a button. Also you should check if the cursor was reset, in order to e.g. pause the game or bring up a game menu. In the Editor the cursor will automatically be reset when you press escape. In the Standalone Player you have full control over the mouse cursor, thus it won't automatically be reset unless you switch applications.
