Introduction
So, you're probably asking yourself, "what is EVT Coding?" EVT coding is the coding language for any quest-related things to do with Knight Online. It has tons of potential, and I'll be explaining what all the functions/commands do and how you would use them.

I'm warning you right now, this is a bit of a long read and EVT coding is very time consuming, so unless you've got time, I wouldn't bother.
Functions/Commands
Basic things you should know :

A is used anytime you're using a IF / Check function

E is used anytime you're using an event function

; is used for commenting - Example
E RUN_EVENT 10601 ; You can write notes here..

-1 is used for noting a space that isn't used, if you're not using one of the supplied spaces you'll have to put a -1.

ALL of EVT Coding must be done in capital letters.

If I missed some of them above, that means I haven't taken the time to figure out what it does. I'm sure if you spend some time on it you'll be able to figure them all out, but I really couldn't care too much about the rest to bother.

Examples and Explanations

Okay, lets say we want to make a NPC where you can turn in a Fragment in for some Bifrost items. I'm only going to use one fragment for this demonstration to save me some time and trouble. I'm going to try and explain everything in detail and hopefully you'll be able to understand how everything works.

END


Now, this is our menu for the Chaotic Generator. First things first, to link a NPC to a certain part of EVT coding, it starts with the EVENT number. In this case, 22001 is linked to 137 byType(In your K_NPC table). There is no real link as to why it's like that, I believe we found out that it was hard-coded into the ebenezer. Now lets move on to the Menu(SELECT_MSG), I'll explain what each one is.

16084 - The ID Number of the NPC(It doesn't need to be correct, it's just for notes.)
61000 - The main text you find at the top when you open a menu, this information is located in 'Quest_Talk_us.tbl'
60000 - The first button in the menu, this is located in 'Quest_Menu_us.tbl'
42010 - This is the first event number you want to have, the menu button you just made above refers to this event.
60001 - This is the second button on the menu, again located in 'Quest_Menu_us.tbl'
52020 - Again, this is the event's number and it refers to the button you made above.
Basically, the same thing keeps going on until you have the whole menu finished.

Now, you should have your Quest_Menu_us.tbl looking something like this now..(Note, we'll only be using the Fragment of Avarice in this guide, but I figured I'd show you how it would be done if you were to make the full thing.)

60000        Fragment of Arrogance
60001        Fragment of Gluttony
60002        Fragment of Rage
60003        Fragment of Sloth
60004        Fragment of Lechery
60005        Fragment of Jealousy
60006        Fragment of Avarice

And your Quest_Talk_us.tbl looking like this.

61000        Welcome to the Chaotic Generator, you can turn in your fragments here for a chance at getting Bifrost Items.
61001 Sorry, you don't have the required fragment.


Okay, the tbls are set, now lets do the database-sided stuff. We'll need to add an exchange into the ITEM_EXCHANGE table.

Your table should look something like below :

Now, the database is done, the TBLs are done, now we need to do the EVT part of it all.

So, first we start off with the Menu.

EVENT 22001
E SELECT_MSG 16084 61000 60000 42010 60001 42020 60002 42030 60003 22040 60004 42050 60005 42060 60006 42070 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 ;
END


Now, 42010 is the Fragment of Avarice, so we'll only be doing that one for now.

EVENT 42010 ; Fragment of Avarice
E RUN_EVENT 42011 ; The RUN_EVENT's basically make one event expand into many others, and links them together, great for checking multiple things.
E RUN_EVENT 42012
END

EVENT 42011 ; First we'll check to see if the item doesn't exist, if it doesn't, End, and display a message.
A HOWMUCH_ITEM 389160000 0 0
E SAY -1 -1 61001 -1 -1 -1 -1 -1 -1 -1
E RETURN
END

EVENT 42012 ; Now we'll check to see if they have a fragment, if you have atleast 1 fragment, roll the dice and run the events.
A HOWMUCH_ITEM 389160000 1 9999
E ROLL_DICE 7 ; Roll a dice 7 times(The number of items we have)
E RUN_EVENT 42013
E RUN_EVENT 42014
E RUN_EVENT 42015
E RUN_EVENT 42016
E RUN_EVENT 42017
E RUN_EVENT 42018
E RUN_EVENT 42019
END

EVENT 42013 ; DICE FOR SHERION
A CHECK_DICE 1
E RUN_EXCHANGE 40001
END

EVENT 42014 ; DICE FOR LUGIAS
A CHECK_DICE 2
E RUN_EXCHANGE 40002
END

EVENT 42015 ; DICE FOR AVEDON
A CHECK_DICE 3
E RUN_EXCHANGE 40003
END

EVENT 42016 ; DICE FOR HELENOID
A CHECK_DICE 4
E RUN_EXCHANGE 40004
END

EVENT 42017 ; DICE FOR HELL BLOOD
A CHECK_DICE 5
E RUN_EXCHANGE 40005
END

EVENT 42018 ; DICE FOR GARP
A CHECK_DICE 6
E RUN_EXCHANGE 40006
END

EVENT 42019 ; DICE FOR ELYSIUM
A CHECK_DICE 7
E RUN_EXCHANGE 40007
END


That's it for that script, you should now be able to finish a Chaotic Generator for your server.




Now I'm just going to make some random examples to explain a few of the functions

Just a simple script below, checks if you have an item, then gives you exp.
