Action Lever Buy System with browsing through wares!

[Evil Hero]

Hello guys,

Havn't released something in quite a while but thought this might be helpful for some people.



with the left lever you go back an item, middle you buy it and right one is to go forward.

local shop =
{
	[2453] = {gold = 1000},
	[2474] = {gold = 2000},
	[2475] = {gold = 2000},
	[2476] = {gold = 2000},
	[2477] = {gold = 2000},
	[2478] = {gold = 2000},
	[2479] = {gold = 2000},
	[2472] = {gold = 2000},
	[2473] = {gold = 3000}
	-- edit this table with the items and the price for them.
}

local order = {2453, 2472, 2473, 2474, 2475, 2476, 2477, 2478, 2479} -- you just have to put all the itemids of the items from the shop in here, in this order the items will get shown once you pull a lever
local config =
{
	level = 1, -- Level requirement to use the shop
	buyLeverAID = 5000, -- actionid of the lever to buy the item
	backLeverAID = 5001, -- actionid of the lever to go back an item
	forwardLeverAID = 5002 -- actionid of the lever to go forward an item
}

function onUse(cid, item, fromPosition, itemEx, toPosition)
local function getItemPos()
	local player = getThingPos(cid)
	return {x = player.x, y = player.y - 3, z = player.z, stackpos = 255}
end
local showItem = getThingFromPos(getItemPos()).itemid
local uid = getThingFromPos(getItemPos()).uid
local function getIndex()
	for a = 1, #order do
		if order[a] == showItem then
			return a
		end
	end
end
local function goBack()
	return getIndex() == 1 and #order or (getIndex() - 1)
end
local function goForward()
	return getIndex() == #order and 1 or (getIndex() + 1)
end
	if getPlayerLevel(cid) < config.level and getPlayerGroupId(cid) < 3 then
		doPlayerSendCancel(cid, "You do not have the required level to use this!")
		return true
	end
	if not isInArray(order, showItem) then
		local tempItem = doCreateItem(order[1], getItemPos())
		doItemSetAttribute(tempItem, "description", "price: ".. shop[order[1]].gold .."")
		return true
	end
	if item.actionid == config.buyLeverAID then
		if getPlayerFreeCap(cid) >= getItemInfo(showItem).weight then
			if doPlayerRemoveMoney(cid, shop[showItem].gold) then
				doPlayerAddItem(cid, showItem, 1)
			else
				doPlayerSendCancel(cid, "You do not have enough gold to buy this.")
			end
		else
			doPlayerSendCancel(cid, "You do not have enough cap to carry this.")
		end
	elseif item.actionid == config.backLeverAID then
		doRemoveItem(uid, 1)
		local tempItem = doCreateItem(order[goBack()], getItemPos())
		doItemSetAttribute(tempItem, "description", "price: ".. shop[order[goBack()]].gold .."")
	elseif item.actionid == config.forwardLeverAID then
		doRemoveItem(uid, 1)
		local tempItem = doCreateItem(order[goForward()], getItemPos())
		doItemSetAttribute(tempItem, "description", "price: ".. shop[order[goForward()]].gold .."")
	end
	return true
end

It's important that you build the lever room exactly like the one on the picture because else the positions wont be working.
You can also do a lot of shops at once, they wont interfere with eachother.

Hope the rest explains itself.



Kind regards, Evil Hero.

not bad

I dont get it, what do u mean by go back item and go forward o.o

 

[Evil Hero]

if you pull the left or the right lever the knight legs in this case will go away and the next item will be spawned on that place.
when you look at the item then you can see the price and with the lever in the middle you buy it.
