'Point at' isn't strictly necessary, although it can hepl to make sure your light is in the right direction. In this case, what is more important is to make sure that your spot light is positioned withinth e same room as your character, with no obstacles in the way to obstruct the light. The same is true of your infinite light as well: since it cannot be positioned within the space, and can only be given an angle, either find a direction where it comes through an open space or window to interact with the scene, or convert it to another spotlight and find somewhere to put it in order to 'cheat' the effect of infinte light settings.
