[Trigger] Pick Units and Revive at Nearest?

[madmuffin]

I'm trying to make a revive system for my Heroes, when they die I want it to pick all Chapels or Altars in the map, pick the nearest one, and resurrect the Hero there. Picking the buildings is no problem, but I can't find a trigger for something like a a Nearest command, how would you do this normally?

EDIT: I found somewhat of a example here, except I get stuck at "Set Distance[2] = (Distance between Point[1] and Point[2])", I can't find a difference between function to set by.

here is the main idea:

you use a unit group and pick every building that can ress him.

now you search inside the unit group for all of the buildings inside the unit group you made doing this

• set X position of dying unit
• set building = random unit from (ress buildings group)
• set Z = position of building
• unit group- pick every unit in (ress buildings group) and do
  • loop
    • set Y position of picked unit
    • if distance between X and Y less than (distance between X and Building)
      • then
        • ----building is the nearest
      • else
        • set building = picked unit
    • custom script: call RemoveLocation(udg_Y)
• custom script: call RemoveLocation(udg_X)
• custom script: call RemoveLocation(udg_Z)
• ress unit at Building <--- the nearest
