Scripting Help: Item Placement on Two Alcoves

[Adamconcept]

Hello potential helpers

I've been working on this problem all day, and the resources and Youtube tutorials Komag put together have been an incredible help, but it's time to admit my shortcomings at programming and organizing my thoughts appropriately for it.

I have a door with an alcove on each side of it, and the goal is to get the player to place a skull in each alcove and activate the door. This is the basic code I've managed to put together:

Code: Select all

function puzzleR101()
   
   local itemName = "skull"
   local alcoveID = R1Alcove1
   for i in alcoveID:containedItems() do
      if i.name == itemName then
playSound("lever")

      else
     
      end
   end
end

The code is repeated on the other alcove, using different names for the function and alcoveID. I tried tying it together with a counter (placed just beneath the "playSound" command), but the problem comes when you use an object that isn't a skull, or remove a skull; it screws up the counter. I've tried this, along with a combination of other scripts which lie far beyond my comprehension, and mucking around with other tools built into Grimrock with no success. If someone can tell me what to look for, or even help me put the code together, that would be amazing. I basically just want a door to open when there's only a skull in each alcove, and to stay shut otherwise. That includes closing itself if a skull is removed.

Thank you again. If this is too complicated to pull off with the resources available, so be it.

As far as I'm concerned make 1 script for every alcove connect them and connect both alcoves to the counter.

Code: Select all

function skullPuzzle()
   for i in dungeon_alcove_4:containedItems() do -- Name of the alcove
      if i.name == "skull" then -- Item category
      counter_2:decrement() -- Counter name
		playSound("lever")
         break
end
end
end

Then connect the counter to the door, you need to try if you like to close the door when a skull is removed or not, as well as connect the alcove to the counter with "Event: deactivate" and "Action: increment".

Almost there; I don't know if I'm missing something. The door won't open unless a skull is in each alcove; that works perfectly fine. As well, if a skull is removed, it closes. That's fine as well. Here's the problem now:

If a skull is in the alcove and another item is placed (say, a torch), then the counter goes up again because it sees a skull during that event. The player can then remove the skull and the door will stay open. :S

I might leave it for now and move on to making the next floor, and hope a solution pops up in the knowledgebases sometime. Again, thank you for the help; it works much better than it did before. It's probably not something most players would pick up on, but two skulls can add a lot on one floor if the player's minotaur has that ability.

Try this witout counter - just link both altars to the areItemsThere() function.. (not tested)

Code: Select all

altar_1_had_skull = false
altar_2_had_skull = false

function altarHasItem(altar,item_name, had_skull)
   
   for i in altar:containedItems() do
      if i.name == item_name then
         if(!had_skull) then
            playSound("lever")
         end
         return true
      end
   end
   
   return false
   
end

function areItemsThere()

   local altar_1_ok = altarHasItem(altar_1, "skull", altar_1_had_skull)
   local altar_2_ok = altarHasItem(altar_2, "skull", altar_2_had_skull)
   
   if(altar_1_ok) then 
      altar_1_had_skull = true 
   end
   if(altar_2_ok) then 
      altar_2_had_skull = true 
   end

   if  altar_1_ok and altar_2_ok then
      altardoor:open()
   else
      altardoor:close()
   end
end

function skullPuzzle()
   for i in dungeon_alcove_4:containedItems() do -- Name of the alcove
      if i.name == "skull" then -- Item category
      counter_2:decrement() -- Counter name
		playSound("lever")
         break
end
end
end

Then connect the counter to the door, you need to try if you like to close the door when a skull is removed or not, as well as connect the alcove to the counter with "Event: deactivate" and "Action: increment".

Found this while stuck on the exact same thing (great minds). My problem is that I'm just learning how to call functions, but don't know how to increment the counter while the item is removed from the alcove (for example, like you can if you remove a torch from the holder). In other words, a player only needs one item instead of two; they can just place it on the alcove, remove it, and replace it and the counter will decrease and open the door. Can someone please help?

IIRC, you can set the alcove to "activate always", then make your "activate" connection to decrement, but also a "deactivate" connection to increment, so if they put an item in and out it will have no net effect

That's more what I mean...I don't know how to script "if [item name] is not equal to [item ID].

Got all excited that help was here...and then...spam.

spam cleaned up

Code: Select all

function checkItems(caller)
	for i in caller:containedItems() do
		if i.name == "skull" then
			counter_1:decrement()
			return
		end
	end
	
	counter_1:increment()
end

Add a counter and change its ID to counter_1 (or change counter_1 in the code to its ID). Set it to have an initial value of 2 and to toggle your door when it receives "any" event. Link your alcoves to the script entity with an "any" event and make sure that 'Activate Always' is unchecked.
