Enables mouse and keybord input for the character that is set to the focus of the camera by SetCameraFocus. Regardless of how many times EnableInput was called in succession, if the player controls are enabled, it is only necessary to call DisableInput once to disable them.
Pressing the escape button disables the input and pressing it again enables it.
Certain actions including HideList, HideCredits, HideNarration, HideList, and HideDialog also enable the input since they are normally called after a corresponding Show action, e.g. ShowMenu, and those actions disable the input.
