In this tutorial, I'll show you how to add "Rune Agent Flasha" into Bloody Ice and let him sell Upgrade Core(High) at 1 Alz.
***********
1, What do I have to know before reading this tutorial?
Where's client and server files?
How to encrypt/decrypt ENC files?
How to edit server's SCP files?
Why I have to know these things?
Cuz I don't show you how to do (search for answer).
2, Add NPC into a map:
By modifying "extra_obj.enc" and "extra_obj_msg.enc" in Client you can add a NPC :)
Here's the way.
a, Edit "extra_obj.enc"
First, with "extra_obj.enc", by adding those lines you'll add an object in to specified map.
<cabal>
<version index="1" />
<extra_object world_id="1">
<extra_stuff id="2" filename="Character\w1rune.ebm" min="-170.873,-25.3112,-244.727" max="215.379,650,172.775" />
<extra_entity type="1" pos="1496,0,4345" rotate="0,0,0,0" scale="1,1,1" disable_cell_radius="1" stuff_id="2" name="extra_npc_003" npc_id="35" npc_tag="0" npc_type="1" />
extra_objectworld_id : ID of World - Map (for full list, check this out
extra_stuff
id : ID of object in current map
filename : 3D Model for object
min : ?
max : ?
extra_entity
type : Object type
0 : Normal Object
1 : NPC
filename : 3D Model for object
pos : NPC Position (All pos is multiplied by 100 for more accuracy)
1st : X
2nd : Z
3rd : Y
rotate : NPC Rotation
1st : Always = 0
2nd : Degree for X axis
3rd : Degree for Z axis
4th : Degree for Y axis
scale : scaling ratio (1,1,1 for normal size)
1st : X
2nd : Z
3rd : Y
disable_cell_radius : Radius of area which the object placed in (player can't cross over that area)
stuff_id : id of extra_stuff which this extra_entity describe about
name : stuff name
npc_id : ID of NPC
npc_tag : ?
npc_type :
1 : Normal NPC
7 : Shop NPC
Other value : Not sure
b, Edit "extra_obj_msg.enc"
File "extra_obj_msg.enc" must have some data to hold NPC name which stored in "extra_obj.enc".
Here is an example.
<cabal_msg>
<version index="1"/>
<nation code="EU"/>
<extra_obj_msg>
<msg id="extra_npc_003" cont="Rune Agent Flasha" />
</extra_obj_msg>
</cabal_msg>
So the thing you have to do here is adding a new <msg /> with corrected value.
msg
id : Same value with extra_entity > name
cont : Name of NPC
OK, now try to run your client. Can you see "Rune Agent Flasha" in Bloody Ice? If not, try again!
3, Modified NPC from Normal NPC to Shop NPC
Now you have to decide, which item you want to sell in that NPC. For example UCH at 1Alz, OK?
a, With "cabal.enc"
Find:
<cabal_world>
Now find: (mean Bloody Ice)
Add this new line to describe about your new NPC.<world id="1" name="world1" type="0" map_file="world_01.mcl"
<world_npc id="35" npc_name="npc01-0035" x="14" y="43" is_obj="0" />
world_npc
id : same id in "extra_obj.enc"
npc_name : follow this pattern "npcXX-YYYY" where
XX : Map ID
YYYY : NPC ID
x : X Position
y : Y Position
is_obj:
0 : Is not Object (is a NPC)
1 : Is a normal Object (non-clickable)
Now add those lines to describe which items your NPC sells:
<shop id="35" >
<item slot_id="0" item_id="1" option="0" reputation_class="-19" duration_id="0" price="1" />
</shop>
shop
id : NPC Id
item
slot_id : Slot on shop screen
item_id : ID of item
option : Option of item
reputation_class : Honor class required to buy (-19 = no required)
duration_id : Item duration
price : Price of item
b, With "cabal_msg.enc"
Add new line to describe about NPC name likes that:
<msg id="npc01-0035" cont="Rune Agent Flasha" />
c, With server file.
Find correct NPC data file for your map (Ex : for Bloody Ice : /etc/cabal/data/data_world/world1-npc.scp)
Open it and add a line to let server know about the NPC which id is 35 (our Rune Agent)
Add into [NpcPos] Flags Index PosX PosY Type IsRangeCheck section
28 0 35 15 43 1 1
Now add new line in this file for 1Alz UCH :)
Add into [ShopLst] NpcsIdx NSetIdx ItemKind ItemOpt ReputationClass DurationIdx Price section
147 35 0 1 0 1 0 1
And that's all, restart your server, and start your client. Now you'll see NPC "Rune Agent Flasha" in Bloody Ice who sells UCH for 1 Alz :)

Here's some NPC XML data which you can use to put into "extra_obj.enc".

For ppl who got problem with synchronizing client/server files. I made a tool (temporary) called "Cabal Enc Tool" :D
It will help you convert data of ENC to SCP and vice versa.
Here's its screenshot and a little of guide for using it.
1, ENC data here
2, Click to convert from ENC (text in #1) to SCP (fill #3 and #4 before click this)
3, NPC Id (must be integer, ex 4,5,7,35,...)
4, Item Index Start (value of 1st row of 1st column in SCP which will be generated)
5, Click to convert from SCP (text in #7) to ENC (no need to fill #3, #4)
6, SCP data column name
7, SCP data here
Get it here
Note : You must have .Net Framework 2.0 in order to use this.
