No pointer capture
An unusual omission in action games playable in a window, where the pointer is allowed to go outside the window without any restriction, possibly causing misclicks outside the game window that cause it to lose focus.
Alternate names: No pointer grab, No pointer confinement
Name variations: No mouse capture, No mouse grab, No mouse confinement
The first video game about No pointer capture was released on September 20, 2004.
Should only be marked in games where this can matter, so a turn-based game or similar progress-only-when-the-player-does-something kind should not be included.
There is no need for actual inclusion of the function as it's far more commonly present than not.
Most or even all game libraries that involve input and display offer a way to do this.
In Linux this can be done with XGrabPointer(), in Windows with SetCapture(), and in SDL it can be done with SDL_WM_GrabInput().
