Getting closest unit

[PrisonLove]

How would I get the closest enemy unit in a straight line from my caster? For example:

X = Caster
-- = area to find unit

  -------------

X 
 
  -------------

So how would I find the closes unit to X in those brackets?

IF you want to make in in GUI do it like tihs:

- need variable "distance" = 0 (start value)
Pick random unit in playable map area and do:
set "distance" = distance between position of "yourUnit" and position of "picked unit"

Pick all units in playable map area and do actions:
if(distance between position of "yourUnit" and picked unit < "distance")
set distance = distance between position of "yourUnit" and position of picked unit


That will get the closest unit BUT it will cause lag if too many units are around :/

should be only used for things like scroll of townportal :/ (like in dota)

If you don't need units in the entire map, limit it to the maximum range you want. For example, pick random unit within X range of ???

Yeah but image there is no unit in that range :/

He wanted to get the closest one

Actually what I am trying to do is pick the closest unit within the current camera bounds. However, I am using a third person camera so I don't know If using current camera bounds would give me all the visible units. Basically I need to storm bolt the closest visible enemy in these camera bounds:
