Quest to check if item exist in inventory?

[covfefe 31]

Hello I need help writing a quest that would detect if an item exists in inventory, but it has to be without login trigger

It only works when I do it like this:

quest item_detect begin
    state start begin
    when login or enter begin
        if pc.count_item(50709)==1 then
        chat("You have x item in your inventory.")
end
end
end
end

My intended result is to make the quest spontaneously spit this chat whenever player receives said item in inventory, whether through exchange, drop, or other means, without waiting for login to trigger it.

If the item you are checking is quest type, then you can only check whether you have picked the item from the ground using the “pick” trigger which is called like this:

quest detect_item begin
	state start begin
		when 50709.pick begin
			chat("You have x item in your inventory.")
		end
	end
end

Quests are limited, you can't check every action you so this isn't possible unless you add a new trigger to your quest manager source file.

The only solution if you want to do this via quest without modifying the source is to use a timer to keep checking for the item but I strongly don’t recommend this.
Regardless, this is how you would do it:

quest detect_item begin
	state start begin
		function get(vnum, count)
			if pc.count_item(vnum) >= count then
				return true
			end
			return false
		end

		when login begin
			timer("item_detector_1", 3)
		end

		when item_detector_1.timer begin
			if detect_item.check(50709, 1) then
				chat("You have x item in your inventory.")
			end
			timer("item_detector_2", 3)
		end

		when item_detector_2.timer begin
			if detect_item.check(50709, 1) then
				chat("You have x item in your inventory.")
			end
			timer("item_detector_1", 3)
		end
	end
end

WoM2 did it so there must be a way. And no I don't want to do it with timer either, that's gonna eat all of my CPU usage..

Sir, I don't think you have any idea how timers work. Also...

The green part is doable in lua, via the method @Owsap explained, the .pick trigger.

The red part is not doable in lua, since there's no trigger for exchange.

 

Timers would be useless here, but they don't "EAT YOUR CPU".

It's easy to make a new trigger for that, but you have to make changes to the sourcecode, you can't do that with what the default Metin2 triggers.
