[Trigger] Automatic Unit Spawn

[mik]

Hey guys,

i wanted to have some Buildings automatically spawn a certain Unit every X seconds (got a continuous timer).

The unit should belong to the player who built the building, and should be of the right type (tank factory spawns a tank, airfield a plane and so on). It should not just be trained there, because i want all the units to spawn together in waves.

Somehow, i dont get it done, nor was i finding a thread for that

hmmm idk what exactly you want but i think i got the most of it.

what i would do is add the buildings to a unit group.than every 10 secs pick every unit in the unit group and spawn a unit at the picked unit. err..maybe this will help

• Spawn Every 10 sec
  • Events
    • Time - Every 10.00 seconds of game time
  • Conditions
  • Actions
    • Unit Group - Pick every unit in Building1 and do (Actions)
      • Loop - Actions
        • Unit - Create 1 Footman for (Owner of (Picked unit)) at (Position of (Picked unit)) facing Default building facing degrees

building 1 is a barracks

when i create it i also put for the owner for picked unit so it spawns for the correct player.
hope that helped.

*EDIT* and here is how you would add the building to the unit group

• Barrack Add To Unit Group
  • Events
    • Unit - A unit Finishes construction
  • Conditions
    • (Unit-type of (Constructed structure)) Equal to Barracks
  • Actions
    • Unit Group - Add (Constructed structure) to Building1

Hope that helped even more

That trigger will leak causing minor lag after a while (well.. Maybe)
In any case. To remove the leak use the following code (it also condenses the whole trigger down to just 1):

• Spawn Every 10 sec
• Events
  • Time - Every 10.00 seconds of game time
• Conditions
• Actions
  • Set TempGroup = (Units in (Playable map area) matching (((Unit - Type of (Matching Unit)) Equal to ('Spawning Structure'))))
  • Unit Group - Pick every unit in TempGroup and do (Actions)
    • Loop - Actions
      • Set TempPoint = (Position of (Picked Unit))
      • Unit - Create 1 Footman for (Owner of (Picked unit)) at TempPoint facing Default building facing degrees
      • Custom script: call RemoveLocation(udg_TempPoint)
• Custom script: call DestroyGroup(udg_TempGroup)

P.S. make sure that you actually put the type of building you want to spawn units in there. Not just 'Spawning Structure' as I have. If you want to use more than one spawning structures. Just use the Or statement in the line where we set the TempGroup.
