I meant Modules.lua not script npc

 

[babalow]

in rev 1040... has doPlayerBuyItemContainer in modules.lua
is the same function?
someone know how make it work?
example maybe ^^

[Elda Swok]

Oh, i knew to delete it lol i was just telling you that there was a spelling error and it should probly be fixed for future refrences, such as other people with the issue of not knowing what to change/delete


Great Script by the way

rep would be awsome!

Yep, anyone can tell something how to make work it in rev 1040??
I have this problem also.

 

[Elda Swok]

i would rep you but, unfortunatly idk how lmfao

 

[Elda Swok]

New Error!

Fixed that error, was wondering though, now when i try to buy a backpack of potions, it says

Would you like to buy |ITEMNAME| for 3800 gold?

any way to try and fix that?

 

[slaw]

Why there still isnt cap checking?

If someone have this in console (when player havent cap)

Lua Script Error: [Npc interface]
data/npc/scripts/runas.lua:onCreatureSay

luaDoAddContainerItem(). Could not add item

global.lua

function doPlayerbuyContainer(cid, container, itemid, charges, cost, count)
	if doPlayerRemoveMoney(cid, cost) == TRUE then
		for i = 1, count do
			local backpack = doPlayerAddItem(cid, container, 1)
			for x = 1, 20 do
				doAddContainerItem(backpack, itemid, charges)
			end
		end
		return LUA_NO_ERROR
	end
	return LUA_ERROR
end

Change to:

function doPlayerBuyItemContainer(cid, container, itemid, charges, cost, count)
	if getPlayerFreeCap(cid) > (getItemWeightById(itemid, 20)*count + getItemWeightById(container, count)) then
		if doPlayerRemoveMoney(cid, cost) == TRUE then

					doAddContainerItem(containerItem, itemid, charges)
				end
			end
			return LUA_NO_ERROR
		end
	else
		return
	end
	return LUA_ERROR
end

Also, this part: (in modules.lua)

elseif(parentParameters.eventType == SHOPMODULE_BUY_CONTAINER) then
			local ret = doPlayerbuyContainer(cid, parentParameters.container, parentParameters.itemid, parentParameters.charges, parentParameters.cost*module.amount, module.amount)

				selfSay(msg)
			else
				local msg = module.npcHandler:getMessage(MESSAGE_NEEDMOREMONEY)
				msg = module.npcHandler:parseMessage(msg, parseInfo)
				selfSay(msg)
			end

change to:

elseif(parentParameters.eventType == SHOPMODULE_BUY_CONTAINER) then
			local ret = doPlayerbuyContainer(cid, parentParameters.container, parentParameters.itemid, parentParameters.charges, parentParameters.cost*module.amount, module.amount)
			if(ret == LUA_NO_ERROR) then
				local msg = module.npcHandler:getMessage(MESSAGE_ONBUY)
				msg = module.npcHandler:parseMessage(msg, parseInfo)
				selfSay(msg)
			elseif(ret == LUA_ERROR) then
				local msg = module.npcHandler:getMessage(MESSAGE_NEEDMOREMONEY)
				msg = module.npcHandler:parseMessage(msg, parseInfo)
				selfSay(msg)
			else
				local msg = module.npcHandler:getMessage(MESSAGE_NEEDMORESPACE)
				msg = module.npcHandler:parseMessage(msg, parseInfo)
				selfSay(msg, cid)
			end

 

[Kavalor]

If it is not too much trouble can someone post up all the scripts that are needed already edited for the LATEST real tfs release by tala? along with an npc that works and does not have any jibberish in it to delete. That will stop the question spam as well as the problems spam. I am having a few problems with this myself and I am not really finding the answers because when i search in moduels for some things to then add code before or after some of them mentioned do not exist. So please would someone post the working stuff so there is less confusion?

 

[mamon_2]

How to add this to the new npc system?

 

[Kavalor]

If you are using the latest TFS version they have allready added this system. Here is a small example piece.

shopModule:addBuyableItemContainer({'bpuh'}, 2003, 2273, 7200, 1, 'Backpack of ultimate healing')

 

[joffily]

I'm using the latest tfs revison but the Advanced Container wont work, and this function shopModule:addBuyableItemContainer too, someone can help me?

 

[mamon_2]

Yep, it isnt working.

 

[gullfisk]

I kinda got i working with TFS mystic spirit.. in a way
Change modules and global.. and rune.lua
This will allow you to buy bp of sd, mana fluids..etc. BUT, as i enabled aol to be
bought from the rune npc-you cannot say "buy aol".. you will have to type "offer"
and buy it from the list. And when you type "bp gmp" the npc respond with "Do you want to buy 1 |ITEMNAME| for 1000 gold coinc?"
But what the hell, it works and saves you players alot of work on repositioning all
the fluids..

So this works for the latest tfs?
Buy Container + NPC Shop System RL?

@UP

When you say:

Kito [1]: bp gmp
Eryn: Do you want to buy 1 |ITEMNAME| for 2000 gold coins?

Or any other kind of BP it always say |ITEMNAME|, maybe if you could fix it and if you say bp sd for example, it should say 1 backpack of sudden death.

It would be nice
