Using an alcove to "combine" two items...

[apendrag0n3]

I am still learning LUA and scripting/modding for GrimRock in general. Here's what I trying to do...

I have an alcove
I want 2 specific items to be placed in the alcove (item_1 and item_2) by the party
Once both items are in the alcove - I want to destroy those items and replace them with item_3

I am not sure what the best way to accomplish this is. Any suggestions/help would be appreciated!


Thanks in Advance!

Updated (thanks minmay):
(it's trickier in LoG1) This requires that you paste this object definition script into one of the lua files found in your mod folder; usually into the objects.lua file.
*In Windows, this is usually found at: "[your documents folder]/almost human/legend of grimrock/dungeons/[name of your mod]/mod_assets/scripts/objects.lua"

When this is done, you need to reload the project, and replace your alcove with the appropriate alcove_combiner assets (that should appear in the editor's object list).

Code: Select all

for x = 1, 3 do
	local name = {"dungeon", "temple", "prison"}

	defineObject{
		--name = "dungeon_alcove_combiner",
		name = string.format("%s_alcove_combiner", name[x]),
		class = "Alcove",
		--model = string.format("assets/models/env/dungeon_wall_alcove.fbx",
		model = string.format("assets/models/env/%s_wall_alcove.fbx", name[x]),
		replacesWall = true,
		anchorPos = vec(0, 0.85, 0.2),
		targetPos = vec(0,1.3,0),
		targetSize = vec(0.6, 0.5, 0.6),
		placement = "wall",
		editorIcon = 8,
		onInsertItem = function(self, item)
						   local first_itemName  = "pitroot_bread"                  
						   local second_itemName = "dagger"
						   local prize = "blueberry_pie"
						   local soundEffect = "item_drop"  				--Defaults to item_drop, but can be changed to suit
						   if item.name == first_itemName or           		--excludes all other item names
						       item.name == second_itemName then
						      
						      for item2 in self:containedItems() do  		--having found one of the two names, it checks the surface for the other one

						         if item2.name ~= item.name then     		--ensures that it excludes duplicate items fed to the next check.  '~='  means "not equal"

						            if item2.name == first_itemName or    	--if it finds a match, it destroys it, and the other one, then adds the prize to the shelf
						               item2.name == second_itemName then
						               print(item.name, item2.name)
						                  setMouseItem()					--must clear mouseItem ~else it remains a bad object on the mouse.	
						                  item2:destroy()
						                  self:addItem(spawn(prize))
						                  playSound(soundEffect)			 --provide sound effect 
						                  					 		
						                  return false                       --must return false to cancel Insert, and MUST exit the loop at first run, or it will compare with destroyed item [==crash]
						            end
						            
						         end 
						      end
						   end
						return true   
	end
	}

Thanks - will try this tonight when I get back home...

And the LoG1 script worked great! Thanks for the help!
