Cast ensnare on nearest unit type..

[pangahas]

How do I make a trigger that would order my unit to cast ensnare on the nearest unit of certain type..
I already did the triggers on how to cast the spell but I want it such that it would cast it to the specific unit nearest from its location..

If the spell has somehow limited range, it would be wise to pick units in range, looping throught every unit in game is slower. (Like pick units in 1000 range and choose from them)
Also, I am not 100% sure here, but using (Temp_Unit_1 Not equal to (Matching unit)) is slower than just picking all and then removing Temp_unit_1 from the group.
