Differentiate between food and drink

[attn]

The next code gives me a dump of vendor's inventory

      max_num = GetMerchantNumItems()
      for i = 1, max_num do
        name, link, quality, iLevel, reqLevel, class, subclass, 
          maxStack, equipSlot, texture, vendorPrice = GetItemInfo(GetMerchantItemLink(i));
        if (subclass == "Food & Drink") then
          has_food = 1
          has_drink = 1
            
          break
        end
      end

and best I can get from lua is subclass for "Food & Drink" category. But to make bot automatically buy food and/or drink I need to know exactly what type is each item.

I've search thru wow api but I didn't find anything. Only "subclass". I've search thru post on this forum but doesn't look like Item has Food/Drink internal type.

One idea to extract this from Item Description. For the food I think it always said "Restore XXX health over xxx sec" and for drink "Restore xxx mana over xxx seconds.". But Item description also not available via wow api unless I mouse over the item. If I'm correct it's in DBCache files. Any suggestions/links how to get it from there for Item (by name of by link) ?

Look at what spell each items casts with GetItemSpell. It will be either "Food" or "Drink".

Now if only I had a way to extract the spell ID (instead of just name & rank) from the items...

Edit: my bad, didn't see that it was in vendor that you needed this.

Thanks,

Just tried but only works if item in my inventory. Doesn't works for items on vendor page .

If your out of process Lists r Ftw

#1 Extract List of Food/Drink/Both

#2 Use List

#3 ????

#4 Done


(Item Id List of/c)

[attn]

What you mean

#2 Use List

I have it just don't know how get Item Spell if it's not in a bag

Quote from wowwiki:

local _, _, Color, Ltype, Id, Enchant, Gem1, Gem2, Gem3, Gem4, Suffix, Unique, LinkLvl, Name = string.find(itemLink, "|?c?f?f?(%x*)|?H?([^:]*):?(%d+):?(%d*):?(%d*):?(%d*):?(%d*):?(%d*):?(%-?%d*):?(%-?%d*):?(%d*)|?h?%[?([^%[%]]*)%]?|?h?|?r?")

"itemLink" should obviously be an item link. If you're enumerating the bags, use GetContainerItemLink(bag, slot).

Actually, this is slightly off topic, but still -- if anyone knows how to get the actual *spell ID* from the item, that would be boss. I use GetItemSpell right now for a poor man's version, but this doesn't give ID, only name and rank. I can manually search all spells for a matching name and rank, but this is potentially slow (yes, I can cache it, but that adds a whole new layer of complexity).

If nobody has it offhand, I'll try RE'ing GetItemSpell today (home from work with a cold) and see if it's easily obtainable (and if it's obtainable from the item ID, that might solve the OP's problem, too).

It's stored in the item cache struct for the item. (As well as a slew of other information)

You get it from COMBAT_LOG_EVENT, i havent found the direct lua function for it.

If not usable, go with reversing.


On topic :

By the merchant I go over each item and check the texture, if texture matches to what i want, and its highest level available that i can use, and its a consumable ...

This has not failed me yet when it comes to restocking drink / food from vendor, note that its untested with all items, just 0-40ish with horde.

Now, there is an even "better" solution. This is written in lua.

function ParseMerchantToopTips()
local mytext, my2text
local text, metext
local numItems = GetMerchantNumItems()
	for i=1, numItems do

			ToolTipForMerchant:SetOwner(UIParent, "ANCHOR_NONE")
			ToolTipForMerchant:ClearLines()
			ToolTipForMerchant:SetMerchantItem(i)
		for i=1,MerchantTooltip:NumLines() do
		
mytext, my2text = getglobal("MerchantTooltipTextLeft" .. i), getglobal("MerchantTooltipTextRight" .. i)
text, metext = mytext:GetText(), my2text:GetText()
	-- this will print all tooltip lines for all items at a merchant.
	print(text,metext)
		
		end
	ToolTipForMerchant:Hide()
	
	end
end

ToolTipForMerchant = CreateFrame("GameTooltip", "MerchantTooltip", UIParent, "GameTooltipTemplate")

Glah. Haven't really looked at the cache yet. Guess it's time...

Thanks, Apoc.

@audible thanks and +1 rep . That's my solution

[rootguy]

I just reversed the GetItemSpell lua function and found exactely what i needed

unsigned long GetItemSpell(unsigned long item_id);

very easy to find 113 bytes from the start of the lua function

For what it's worth you can also just use LibPeriodicTable to get more information about an item.
