Problem with TFS npc's

[christiandb]

Hey,

I've added some others npc's to my TFS server but when I say hi they aren't responding. The bug I get:

[26/08/2008 20:55:10] Lua Script Error: [Npc interface]
[26/08/2008 20:55:11] data/npc/scripts/seller.luanCreatureSay

[26/08/2008 20:55:11] data/npc/scripts/seller.lua:39: attempt to call global 'getDistanceToCreature' (a nil value)
[26/08/2008 20:55:11] stack traceback:
[26/08/2008 20:55:11] data/npc/scripts/seller.lua:39: in function <data/npc/scripts/seller.lua:36>

Does anyone know how to fix this?

Thanks in advance,

Chris~

You have something wrong in lines 36 and 39, and its problem with "getDistanceToCreature". Can you give here your seller.lua ? ;p

Chris~

This is sayin that that command "getdistancetocreature" is not a command the server recognizes, i had this problem before with rune npc when tryin to do bp sd as a buyable item.

I have not yet figured this out but im close when i do ill let u know.

HOWEVER! for the shovel and those single items try this :

<parameter key="shop_buyable" value="backpack,1988,20;pick,2553,10;shovel,2554,20;rope,2120,50"/>

(if the script is in npcname.xml file)Make sure each added item has :shovel,2554,20; formate.
shovel = name, 2554 = item id, 20 = price. and always end with a ";"

(if script is in the .lau file)In rune script and such use this format.
shopModule:addBuyableItem({'wand of vortex', 'vortex'}, 2190, 500, 'wand of vortex')

change the name, itemid(2190), price(500) and thats a working script right there

Hope i help you. I am a ultra noob scripter.

You helped me, but the problem is when I need to do that with all the NPC's it will take ages to fix it
