Item Specific Container

[EnochDagor]

I was thinking a neat item might be a container for a specific type of item.

For example, an herb satchel.

So, I created the item from a base_item. Here's my container definition where I was trying the theory in general... basically, if I can get the item to remove itself and reattach to the mouse, I want to do that... then I can do it by type.

Code: Select all

	{
		class = "ContainerItem",
		containerType = "chest",
		onInsertItem = function(self, item, slot)
			local theObj = self:getItem(slot)
			if theObj ~= nil then
				self:removeItemFromSlot(slot) 
				setMouseItem(item)
			end
			return false
		end 
	},

This code works but the mouse item does not get set. Well, that's not entirely accurate. The Mouse Item gets set while I'm in scope of the function (if I do a getMouseItem and print the ID its the correct ID). But once the scope is left, I lose the item.

Any ideas on what I am doing wrong?

You need to call setMouseItem() in a delayedCall and it should work.

Replace setMouseItem with something like:

Code: Select all

delayedCall("script_entity_01", 0.1, "giveMouseItem", item.go.id)

In a script entity with id of "script_entity_01", define this function:

Code: Select all

function giveMouseItem(itemId)
    local itemGO = findEntity(itemId)
    setMouseItem(itemGO.item)
end

Did you guys ever suceed in this script?

I tried to create a Spellbook item that can only fit "SpellScrollItem" but i failed

When i try to put an item into the Spellbook it just vanishes. Im probably just too bad at scripting though

[EnochDagor]

Unfortunately, no. I tried to do the delay but it still did not work 100% (and actually lead to a nasty bug where items insta-charged which I saved for later use).

Instead, I simply allowed it for my current scenario and put an OOC to not mess with the item. I will go back at some point and try again when I get time.

Thanks for the reply

At least i know that i dont have to bother with the "spellbook" anymore. I am using another Spell scroll learn script now anyway..so no spellbook needed

Put a script entity called "script_entity_1" in your mod, and put this code in it:

Code: Select all

function giveMouseItem(item_id, altar_id)
	local item_local = findEntity(item_id)
	local altar_local = findEntity(altar_id)
	
	if ((item_local ~= nil) and (altar_local ~= nil)) then
		setMouseItem(item_local.item)
		altar_local:destroy()
	end
end

This bag only accepts keys:

Code: Select all

defineObject{
    name = "key_bag",
    baseObject = "base_item",
    components = {
        {
            class = "Model",

            gfxIndex = 82,
            gfxIndexContainer = 482,
            weight = 0.4,
            fitContainer = false,
        },
        
        {
            class = "ContainerItem",

            openSound = "container_sack_open",

            onInsertItem = function(self, item, slot)
                if (item:hasTrait("key")) then
                    self.go.data:set("item_id", nil)

Simpler version of the bag code:

Zo would you be able to create a new (Mortar) eg: The dm_tool_box from Germmany. When you put items in the Tool Box you can make things like a Torch, hammer etc... It will need to have a recipe function like the mortar though. Ok if you can give me a pm please. This would be super awesome for everyone thxs
