Line of sight (UFO2000)
All units in UFO2000 have line of sight. A unit's line of sight encompasses any objects or other units which are:
- Within visible range (17 tiles at the maximum light level of 16 and 2 at the minimum light level of 6)
- Not blocked by terrain or smoke
- Within the unit's field of view (FOV, also field of vision)
FOV in horizontal plane
Just like in X-COM, all units have a 90 degree field of vision, radiating outward in a cone in whichever direction they are facing.
FOV in vertical plane
Units in UFO2000 can not see downwards as well, as upwards. They can see up to 85 degrees up but only 45 degrees down in vertical plane.
There is a tweak request in the bugtracker for making the FOV in the area below to be identical to the FOV in the area above, see http://ufo2000.net/mantisbt/view.php?id=628.
