scripting help

I also tried in a new project and same warning

That's very peculiar that I don't get an error with mine, but yours does.

Okay, try this variation on the script:

Code: Select all

altar_1.surface:addConnector('onAcceptItem', self.go.id, "itemSwap")
function itemSwap(surface, item)
	local checkItem = "rock"
	local itemReplacement = "figure_skeleton"
		if item.go.item:getStackSize() == 1 and
			item.go.name == checkItem then
			item.go:destroyDelayed()
			surface:addItem(spawn(itemReplacement).item)
			--optional effect 
			surface.go:createComponent('Particle'):setParticleSystem('beacon_crystal')
			surface.go.particle:setDestroySelf(true)
			surface.go.particle:fadeOut(1)
			surface.go:playSound('teleport')
			return false
		end
end

This one gives me no errors, but handles things slightly different than before; based on a hunch. The original script did have a bug—though it didn't crash for me. This version fixes that bug.

that works thank you.

Hi Issac
Tried using your variation of the script but when you place the rock on the altar I end up with 2 'skeleton figurines' every time
and the particle system does not fade out, any ideas?

I am trying to use this but instead the player puts some items on a pedestal then hits a button which checks for items and spawns them on the pedastel

IIRC you wanted a script that turns multiple items into a single new item, like crafting potions.

Code: Select all

function transformItems(button)
	local input_item_names = { rock = false, branch = false }
	local output_item_name = "cudgel"
	local surface
	
	local alcove = findEntity("dungeon_alcove_1")
	if alcove and alcove.surface then
		surface = alcove.surface
	else
		print("Entity doesn't exist or has no surface component: dungeon_alcove_1")
		return
	end
	
	-- If any of the input items is on the surface, mark it as present in input_item_names
	for _, item in surface:contents() do
		if input_item_names[item.go.name] ~= nil then
			input_item_names[item.go.name] = true
		end
	end
	
	-- If at least one input item is missing from the surface, exit the function
	for _, present in pairs(input_item_names) do
		if present == false then
			return
		end
	end
	
	-- Destroy the input items
	for _, item in surface:contents() do
		if input_item_names[item.go.name] == true then
			-- Mark the item as destroyed in input_item_names
			-- So only one instance of the input item gets destroyed
			input_item_names[item.go.name] = false
			item.go:destroyDelayed()
		end
	end
	
	-- Add the output item to the surface
	surface:addItem(spawn(output_item_name).item)
	playSound("secret")
	hudPrint("The alcove has created a new " .. output_item_name .. ".")
end

Thanks. How would I make it so it destroys the items even if they are not the right ones?
