Count Items in Region

[Mechcash]

Hey People,

I made this trigger.

• Spawn Items
  • Events
    • Time - Every 0.35 seconds of game time
  • Conditions
  • Actions
    • Set VariableSet ItemLocation = (Random point in Region 000 <gen>)
    • Item - Create SpawnedItems[(Random integer number between 1 and 2)] at ItemLocation
    • Custom script: call RemoveLocation (udg_ItemLocation)

Now I need a way to count the amount of spawned items, so they stop spawning when a certain number of items is reached in the region. When the number falls under the max value, items should start Spawning again.

I just find the integer for "Count Units" , but is there something similar for items?

Thanks!

native EnumItemsInRect takes rect r, boolexpr filter, code actionFunc returns nothing

I believe you can find this in the Item category if you're using GUI, probably something like Pick Items In Region.

The exact trigger you're looking for is in this thread:
Help, pick every item region < 5 then spawn item.

And the action:

• Item - Pick every item in Region000 <gen> and do (Actions)

The exact trigger you're looking for is in this thread:
Help, pick every item region < 5 then spawn item.

And the action:

• Item - Pick every item in Region000 <gen> and do (Actions)

So I came up with this:

• Limit 1
  • Events
    • Time - Every 0.45 seconds of game time
  • Conditions
  • Actions
    • Set VariableSet ItemLocation = (Random point in Region 000 <gen>)
    • Set VariableSet IntegerVariable = 0
    • Item - Pick every item in Region 000 <gen> and do (Actions)
      • Loop - Actions
        • Set VariableSet IntegerVariable = (IntegerVariable + 1)
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • IntegerVariable Less than or equal to 500
          • Then - Actions
            • Item - Create SpawnedItems[(Random integer number between 1 and 3)] at ItemLocation
          • Else - Actions
    • Custom script: call RemoveLocation (udg_ItemLocation)

Did I do the leak clear of the location in the right spot or does it need to be inside the if then else function?

Move:

• If (All Conditions are True) then do (Then Actions) else do (Else Actions)

So it's right above:

• Custom script: call RemoveLocation (udg_ItemLocation)

So it's outside of the Pick every Item function.

And yes, that's the correct spot for the remove location. Otherwise, you'd attempt to remove the location X times, X being the total number of Items in Region 000.

If you did it the wrong way it would look like this:
Create a Point
Pick every Item and do:
Remove Point <-- this happens once for EACH picked item

Works perfect!

Also, a very minor optimization would be to only create the Point if you actually create the Item.
