How to keep mouse cursor in the screen ?

Hi guys,
I builded a little sample game with first person shooter script. everything works well with it, and its windowed screen.

I start the game and when the mouse goes of the screen the character turns too much.

I want that the mouse cursor cannot go out of the screen. What is the way to do that ?

Any help would be apreciatted...

 

I tried hiding the cursor but it didn't work. The cursor can still go out of the window. Maybe the screen object can be helpful

 

Try Screen.lockCursor. It also hides the cursor.

 

Screen.lockCursor may be your only option in this case.
