How many items in total? Can you make a list and an example of the npc conversation ingame (how it will look like when you talk to the npc).
me: Hi
npc: Hello there NAME! I'm trading my special weapons for your items !
me: Weapons
npc: You can trade yourself a Warlord sword, Spellbook of dark mysteries and Royal crossbow
me: Royal crossbow
Npc: Do you want to exchange arbalest and 100 demonic essences for a royal crossbow ?
Like that with all items
Warlord sword = 100 demonic essence + magic sword
spellbook of d = 100 demonic essence + spellbook of lost souls
royal crossbow = 100 demonic essence + arbalest
These items for now, but i might add a mace and a axe for the NPC for knights benefits.
You can change the npc conversations but i would like it something similar

Also i'm new to this scripting. I'm actually learning could you add me somewhere and just help me sometimes ? I'm not looking for someone to make my scripts for me but i'm looking for someone that might coach me a little bit. So i can learn it properly. This npc is the current problem we gotta fix

npcHandler:addModule(FocusModule:new())Hey, it works great but there is only 1 problem.
When i write HI to him he says
16:06 Robbie the dealer: Welcome, Wyrome! I have been expecting you.
I want him to say Hello there Wyrome! I got some weapons for exchange.
Or something like that, so people understand that they should write weapons to know what weps
Use greetmessage in the xml of the npc, like this
Code:
<?xml version="1.0" encoding="UTF-8"?>
<npc name="Robbie the dealer" script="exhchange.lua" walkinterval="2000" floorchange="0">
<health now="100" max="100"/>
<look type="274" head="0" body="113" legs="78" feet="114" addons="3"/>
<parameters>
<parameter key="message_greet" value="Hello there |PLAYERNAME|! I'm trading my special {weapons} for your items!"/>
</parameters>
</npc>
