Spawn Units in an area.

[DESTROYER123]

Hello everyone!
I need a trigger script in which a unit is spawned in a specific region every 10 seconds of the game.
But I don't want the spawned units to overcome the maximum number of 7.
I don't know if this is the right forum but I've tried it 3 times but it leaks.

Anyway,
Thanks!

Wow!
You're really too fast.
However I don't want the unit's to be spawned at the playable map area and that causes a problem with the 3rd trigger.
Anyway I'll get some ideas and fix it.
Thanks!!!

Replace "playable map area" with your region

Will this also work??

• Prepare Region 015
  • Events
    • Time - Every 7.00 seconds of game time
  • Conditions
  • Actions
    • Set Point0008 = (Random point in Region 015 <gen>)
    • Unit Group - Pick every unit in (Units in Region 015 <gen>) and do (Actions)
      • Loop - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Unit-type of (Picked unit)) Equal to Skeletal Minnion (1)
          • Then - Actions
            • Unit Group - Add (Picked unit) to SkeletalSmallMinionsReg15
            • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
              • If - Conditions
                • (Number of units in SkeletalSmallMinionsReg15) Less than 7
              • Then - Actions
                • Unit - Create 1 Skeletal Minnion (1) for Neutral Hostile at Point0008 facing Default building facing degrees
                • Custom script: call RemoveLocation(udg_Point0008)
              • Else - Actions
          • Else - Actions

No. Instead of checking the number of uinits in region make a unit group for them and check the number fo units in it.
Edit// Will add trigger after 10 min.

Will that do it??

• Prepare Region 015
  • Events
    • Time - Every 5.00 seconds of game time
  • Conditions
  • Actions
    • Unit - Create 1 Skeletal Minnion (1) for Neutral Hostile at (Random point in Region 015 <gen>) facing Default building facing degrees
    • Unit Group - Add (Last created unit) to SkeletalSmallMinionsReg15
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Number of units in SkeletalSmallMinionsReg15) Greater than 7
      • Then - Actions
        • Do nothing
      • Else - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Number of units in SkeletalSmallMinionsReg15) Less than 7
          • Then - Actions
            • Unit - Create 1 Skeletal Minnion (1) for Neutral Hostile at (Random point in Region 015 <gen>) facing Default building facing degrees
            • Unit Group - Add (Last created unit) to SkeletalSmallMinionsReg15
          • Else - Actions

I know it leaks point but I'll fix that.

No. The do nothing is absolutely unnecesary. The Greater than 7 too it should be equal and the overal trigger is much smaller like:

• Untitled Trigger 002
  • Events
    • Time - Every 10.00 seconds of game time
  • Conditions
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Number of units in CREEP_GROUP) Equal to 7
      • Then - Actions
      • Else - Actions
        • Set TempPoint = (Random point in SPAWN_REGION <gen>)
        • Unit - Create 1 CREEP for Neutral Hostile at TempPoint facing Default building facing degrees
        • Unit Group - Add (Last created unit) to CREEP_GROUP
        • Custom script: call RemoveLocaton(udg_TempPoint))

There would be a second trigger to remove dead units:

• Untitled Trigger 003
  • Events
    • Unit - A unit Dies
  • Conditions
    • ((Triggering unit) is in CREEP_GROUP) Equal to True
  • Actions
    • Unit Group - Remove (Triggering unit) from CREEP_GROUP

Wait a sec... doesn't a dead unit auto removed from unit group or it needs to decay...

That was the thing I was about to do!
Thanks!!

You need to remove them with triggers.
