First I would "fix" your Regions so that they work properly:
-
Region Fixer
-
Events
-
Conditions
-
Actions
-
Custom script: local rect r
-
-------- --------
-
-------- Set this to the number of Regions you want to fix: --------
-
Set VariableSet RegionFixer_Count = 2
-
-------- --------
-
-------- Assign each Region you want to fix: --------
-
Set VariableSet RegionFixer_Region[1] = Archer Trigger Region <gen>
-
Set VariableSet RegionFixer_Region[2] = Archer Starting Region <gen>
-
-------- --------
-
-------- Once our variables are setup, loop through all of the Regions and adjust them so that they have the correct size: --------
-
For each (Integer A) from 1 to RegionFixer_Count, do (Actions)
-
Loop - Actions
-
Custom script: set r = udg_RegionFixer_Region[bj_forLoopAIndex]
-
Custom script: call SetRect(r, GetRectMinX(r) - 32., GetRectMinY(r) - 32., GetRectMaxX(r) + 32., GetRectMaxY(r) + 32.)
-
Custom script: set r = null
Regions have issues related to their coordinates which can make the Enters/Leaves Events run before the Unit is actually in/out of the Region. This makes Conditions like "Is unit in Region" fail in cases where you'd expect it to work.
Then you can use an Integer variable and Unit Group variable to determine how many units are in your region. Here are the triggers.
First, add 1 to our Integer and check if it's equal to 1 when we enter the region. If it is 1 then the archers should advance forward:
-
Enter Region
-
Events
-
Unit - A unit enters Archer Trigger Region <gen>
-
Conditions
-
((Owner of (Triggering unit)) controller) Equal to User
-
(Unit-type of (Triggering unit)) Not equal to Goblin Land Mine
-
Actions
-
Set VariableSet Units_In_Region = (Units_In_Region + 1)
-
Unit Group - Add (Triggering unit) to Enter_Group
-
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
-
If - Conditions
-
Units_In_Region Equal to 1
-
Then - Actions
-
Unit Group - Pick every unit in Archer_Group and do (Actions)
-
Loop - Actions
-
Unit - Order (Picked unit) to Attack-Move To (Center of Archer Advance Region <gen>)
-
Trigger - Turn on Unit Dies In Region <gen>
-
Else - Actions
Next, subtract 1 from our Integer and check if it's equal to 0 when we leave the region. If it is 0 then there are zero units in the region:
-
Exit Region
-
Events
-
Unit - A unit leaves Archer Trigger Region <gen>
-
Conditions
-
((Owner of (Triggering unit)) controller) Equal to User
-
(Unit-type of (Triggering unit)) Not equal to Goblin Land Mine
-
Actions
-
Set VariableSet Units_In_Region = (Units_In_Region - 1)
-
Unit Group - Remove (Triggering unit) from Enter_Group.
-
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
-
If - Conditions
-
Units_In_Region Equal to 0
-
Then - Actions
-
Unit Group - Pick every unit in Archer_Group and do (Actions)
-
Loop - Actions
-
Unit - Order (Picked unit) to Move To (Center of Archer Starting Region <gen>)
-
Trigger - Turn off Unit Dies In Region <gen>
-
Else - Actions
Also, a unit dying doesn't make it "leave" a region so we need to account for this:
-
Unit Dies In Region
-
Events
-
Conditions
-
((Triggering unit) is in Enter_Group.) Equal to True
-
Actions
-
Trigger - Run Exit Region <gen> (ignoring conditions)
This will ensure that the archers only advance when there's a unit in the region owned by a User that
ISN'T a goblin land mine (change it to dwarf land mine in your case). I assume when you said Human player you meant a User.
Note that these triggers leak a Point whenever we order the units to move/attack-move to the (Center) of a region.
You're also leaking A LOT of Unit Groups by doing this:
-
(Number of units in (Units in ArchersAttack <gen> matching ((Unit-type of (Matching unit)) Equal to Warrior)))
