There are 15 creep camps that unlock a loot chest when all of them are dead. Problem is when the camp respawns, I can't figure out how to check if that camp is dead. So for the respawns we just make the chest vulnerable and ignore the "kill the entire camp" mechanic to get loot. Is there an easy way to fix this? To make sure the respawns also need to be killed.

The first round of loot is handled by GUI loot tables. and the respawn is handled by trigger. But I can't think of a good way to make the chests vulnerable once the camps are dead. Not really sure how to check where the creep camp units are in the array.

Use Unit Group arrays to track multiple groups of Units. Use a Unit Indexer or a Hashtable to link each Unit to their Unit Group. Then whenever a unit dies you can check to see if it is linked to a group and go from there. If it has a group then remove it from that group, check if that group is empty and proceed to your respawn logic if necessary. This is clean and highly efficient.

Here's a simple Unit Indexer example:

Link and Add units to their Unit Group when they're created or at the start of the map if they're pre-placed (Elapsed time 0.01s):
  • Actions
    • Unit - Create 1 Creep...
    • Set Variable CV = (Custom value of (Last created unit))
    • Set Variable Group_Number = 3
    • Set Variable Creep_Group_Number[CV] = Group_Number
    • Unit Group - Add (Last created unit) to Creep_Groups[Group_Number]
Get and Remove units from their Unit Group when they die:
  • Events
    • Unit - A unit Dies
  • Conditions
    • Creep_Group_Number[(Custom value of (Triggering unit))] Greater than 0
  • Actions
    • Set Variable CV = (Custom value of (Triggering unit))
    • Set Variable Group_Number = Creep_Group_Number[CV]
    • Unit Group - Remove (Triggering unit) from Creep_Groups[Group_Number]
    • If all conditions are true then do (Actions)
      • If - Conditions
        • (Creep_Groups[Group_Number] is empty) Equal to True
      • Then - Actions
        • -------- All of the units in the group have died --------
      • Else - Actions
        • -------- At least one unit is still alive --------
Important:

1) Unit Group arrays need to be initialized before becoming usable, so make sure that you set the Size inside of the Variable Editor to a large enough number. For example, setting it to 100 would allow you to use an Index range of [0] to [100]. In other words, you can have 100 different Unit Groups.

2) Most Unit Indexers will recycle the custom values of dead units. This could be problematic for a respawn system since you don't want your dead unit's custom values to change and lose track of their data. That means switching to a Hashtable could be necessary. The logic would remain mostly the same, just replace all instances of Creep_Group_Number[] with a saved Integer value inside of a Hashtable.

3) Removed units won't fire the Event "A unit Dies", you should be aware of this! If you must Remove a creep then you can kill it first to run the Event:
  • Actions
    • Unit - Kill (Triggering unit)
    • Unit - Remove (Triggering unit) from the game

Thank you I think I'll use this system. However I'm confused how I can reference certain units in the index if they are pre placed. How do I tell the indexer exactly which 5 units should be in a certain group?

They're preplaced so you already have a direct reference to each of them.
  • Unit Group - Add Footman 0003 to ...
  • Unit Group - Add Footman 0004 to ...
  • Unit Group - Add Footman 0005 to ...
You could also use Regions if that'd be easier, like have a Region covering each "Creep Camp", then you can use the Pick Every Unit In Region action to help simplify things.
