You can do something like this:

• Trigger
• Events
  • Map Initialization
• Conditions
• Actions
  • Hashtable - Create a hashtable
  • Set Hashtable = (Last created hashtable)

• Trgger2
• Events
  • Unit - A unit is issued an order targeting a point
• Conditions
  • (Issued order) Equal to (order(townhall))
• Actions
  • Set Point = (Target point of issued order)
  • Set Temp_Group = (Units within 2000.00 of Points[1] matching (((Matching unit) belongs to an enemy of (Owner of (Triggering unit))) Equal to True) and ((Matching unit) is a town-hall-type unit) Equal to True)
  • If (All conditions are true) then do (Actions) else do (Actions)
    • If - Conditions
      • (Number of units in Temp_Group) Not Equal to 0
    • Then - Actions
      • Unit - Create 1 dummy for (Owner of (Triggering unit)) at Points[1] facing default building degrees
      • Hashtable - Save Handle of (Triggering unit) as 0 of (Key(Last created unit)) in Hashtable
      • Unit - Add 0.01 Generic expiration timer to (Last created unit)
    • Else - Actions
  • Custom script: call RemoveLocation (udg_Point)
  • Custom script: call DestroyGroup (udg_Temp_Group)

• Trigger3
• Events
  • Unit - A unit dies
• Conditions
  • (Unit-type of (Triggering unit)) Equal to dummy
• Actions
  • Set Builder = (Load 0 of (Key(Triggering unit)) from Hashtable)
  • Unit - Order Builder to Stop
  • Custom script: call IssueImmediateOrderById (udg_Builder, 0xD0008)
  • Hashtable - Clear all child hashtables of (Key(Triggering unit)) in Hashtable
  • Game - Display to (Player Group(Owner of (Triggering unit))) the text: "An enemy's base is too near!"
