Locating items in player equipment by action id.

[tarjei]

Hi, recently I discovered my old function wich I was excited about when I was newbie in scripting. It was parsing tree of backpacks that locates items by specific actionid you give to function. I was so annoyed by unprofesionality of this code that I rewrote this and release it now to public. Maybe someone will find it usefull in some kind of quests or when you make events perhaps.

Here is the code.

Locate = {

}

function Locate:new()
		local obj = {}
		--specification
		obj.action = nil
		obj.itemid = nil
		---------------
		obj.found = {}
		self.__index = self
		
		setmetatable(obj,self)
		return obj
end
function Locate:setParam(name, value)
		if name == "action" then
			self.action = value
		elseif name == "itemid" then
			self.itemid = value
		elseif name == "uid" then
			self.uid = value
		end
end
function Locate:insert(v)
		table.insert(self.found, v)
end

function Locate:checkContainer(uid)
   local size = (isContainer(uid)  and getContainerSize(uid) or 0)
   for i = 0, size do    
		local tmp = getContainerItem(uid, i)
		self:compare(tmp)
		--print(getItemName(tmp.uid))
		if type(tmp) ~= "boolean" and isContainer(tmp.uid) then
		  self:checkContainer(tmp.uid)
			
		end	
   end
end
function Locate:compare(item)
		local checkItemId = (self.itemid ~= nil)

		if  checkItemId then
			if (item.itemid == self.itemid and self.action~= nil and item.actionid == self.action) then
				self:insert(item.uid)
			end
		else
			if (self.action~= nil and item.actionid == self.action) then
				self:insert(item.uid)
			end		
		end
end	

function Locate:startLocating(cid)
	for x = 1,10 do
		local slotItem = getPlayerSlotItem(cid,x)
		self:compare(slotItem)
		if isContainer(slotItem.uid) == true then
			self:checkContainer(slotItem.uid)
		end
	end
	
	doCreatureSay(cid,table.maxv(self.found).." foud items",1)
end

function getItemsByActionId(cid,action)
	local find = Locate:new()
	find:setParam("action", action)
	find:startLocating(cid)
	return find.found
end
function getItemsByItemidAndActionId(cid,itemid, action)
	local find = Locate:new()
	find:setParam("action", action)
	find:setParam("itemid", itemid)
	find:startLocating(cid)
	return find.found
end

As you can see it comes to 2 functions getItemsByActionId(cid,action) and getItemsByItemidAndActionId(cid,itemid, action).
They both returns array with uids of fiting items.
But lets give some example.

   for k, v in pairs(getItemsByActionId(cid,2000)) do
     print("Hey my uid is: "..v)
   end

Have fun with this simple code, I hope you can find it usefull somehow.
Cheers.

Bro this is some badass logic. I know it is outdated at this point but this is a great example of OOP. I love it and learned from it still. Great release! Thank you.
