Making a Unit Cast an Ability on Every Unit Near Every Unit in a Unit Group

[Azrooh]

...The title's a bit of a mouthful. But hopefully these triggers will explain it:

• Plague
  • Events
    • Time - Every 0.25 seconds of game time
  • Conditions
  • Actions
    • Unit Group - Pick every unit in (Units in (Playable map area) matching (((Matching unit) has buff Coughing Plague) Equal to True)) and do (Actions)
      • Loop - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • ((Picked unit) is in PlagueGroup) Not equal to True
          • Then - Actions
            • Unit Group - Add (Picked unit) to PlagueGroup
          • Else - Actions
    • Unit Group - Pick every unit in PlagueGroup and do (Actions)
      • Loop - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • ((Picked unit) is in PlagueGroup) Equal to True
          • Then - Actions
            • Region - Center PlagueIncubationRegion <gen> on (Position of (Picked unit))
          • Else - Actions

• Plague 2
  • Events
    • Time - Every 0.25 seconds of game time
  • Conditions
  • Actions
    • Unit Group - Pick every unit in (Units in PlagueIncubationRegion <gen> matching (((Matching unit) is in PlagueGroup) Not equal to True)) and do (Actions)
      • Loop - Actions
        • Set DiseasePoint = (Position of (Picked unit))
        • Unit - Create 1 PlagueDummy 5 for Neutral Extra at (Center of (Playable map area)) facing Default building facing degrees
        • Unit - Order (Last created unit) to Neutral - Parasite (Picked unit)
        • EGUI Leak - Remove DiseasePoint
        • Unit - Remove (Last created unit) from the game

What I'm trying to do here is cause a dummy to cast Parasite on every unit that's near a unit in the unit group PlagueGroup.
This trigger doesn't work, but I think I'm on the right track. How would I fix it?

Well, I see one issue with the Region. The way you have it set up, it moves the region around a lot without anything actually happening.

I would suggest that instead of moving a region, you have them give a buff to each other unit within x meters, then check for the buff.

Try these triggers:

• Plague
  • Events
  • Time - Every 1 seconds of game time
    • Comment: Every .25 seconds is overkill and might lead to lag. I'd dial it back to 1 or 2 seconds.
  • Conditions
  • Actions
  • Unit Group - Pick every unit in (Units in (Playable map area) matching (((Matching unit) has buff Coughing Plague) Equal to True)) and do (Actions)
  • Loop - Actions
  • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
  • If - Conditions
  • ((Picked unit) is in PlagueGroup) Not equal to True
  • Then - Actions
  • Unit Group - Add (Picked unit) to PlagueGroup
  • Else - Actions
  • Unit Group - Pick every unit in PlagueGroup and do (Actions)
  • Loop - Actions
  • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
  • If - Conditions
    • ((Picked unit) is in PlagueGroup) Equal to True
  • Then - Actions
    • Player - Enable Spellbook for (Owner of (Picked Unit)
    • Unit - Set level of Plague Spreading for (Picked Unit) to 2
    • Player - Disable Spellbook for (Owner of (Picked Unit)
      • Comment: Plague Spreading is a simple Aura ability based off of Devotion Aura. Make sure to set it to +0 armor. The spell book is to hide the icon from the unit. Set up Plague Spreading to have 2 levels and have it give a unique buff at level 2 and nothing at level 1. Stick the Plague Spreading in the Spellbook and give the spellbook to every single unit. Put a Player - Disable Spellbook for each player in your initialization trigger.
  • Else - Actions
  • Do Nothing

Now for the actual parasite trigger:

• Plague 2
  • Events
  • Time - Every 1 seconds of game time
  • Conditions
  • Actions
  • Unit Group - Pick every unit in (Units in (Playable map area) matching (((Matching unit) has buff SpreadingPlagueBuff [Comment: Put the unique buff from the aura here) Equal to True)) and do (Actions)
  • Loop - Actions
  • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
    • If - Conditions
      • ((Picked unit) is in PlagueGroup) Equal to False
    • Then - Actions
      • Set DiseasePoint = (Position of (Picked unit))
      • Unit - Create 1 PlagueDummy 5 for Neutral Extra at (Center of (DiseasePoint)) facing Default building facing degrees [Comment: You had it at the Center of Playable Map Area, fixed to be at the plagued unit.]
      • Unit - Order (Last created unit) to Neutral - Parasite (Picked unit)
      • EGUI Leak - Remove DiseasePoint
      • Unit - Remove (Last created unit) from the game
    • Else - Actions
      • Do Nothing

Lastly, we need a new trigger that handles if a unit loses Coughing Plague.

• Events
  • Time - Every 1 seconds of game time
  • Conditions
  • Actions
  • Unit Group - Pick every unit in (PlagueGroup) and do (Actions)
  • Loop - Actions
  • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
    • If - Conditions
      • ((Picked unit) has buff matching Coughing Plague) Equal to False
    • Then - Actions
      • Remove (Picked Unit) from (PlagueGroup)
    • Else - Actions
      • Do Nothing

That should handle all the group stuff for ya.

The entire point of casting the spell is the buff. It's just a dummy spell.
What I'm stuck on is getting the spell to cast on everyone so they get the buff.


E: I see how that works. Would there be a way to 'time' the buff, so it expires?

E2: I posted before you finished it. Thanks!

Your trigger is full of leaks...
