Understand hex code for items 1.02Q

[Z80]

Hi folks,

I know its not a brand new thingy, but I put all together in a nice working sheet,
so its a big help, when you are trying to adapt your website or other tools you made to mange your server, for the new items of season 2, which you will find in goe's release 06/04 for example.

Thanks to goe for his great release, liselotte for the best English item(kor).txt, CZF for the editor 1.5, and all reagzoners which are sharing knowledge ^^!

Re: [Guide] Understand hex code for items 1.02Q

A good guide, tnx, but you have some mishaps.
Lets try it again, this time my way

Use the attached word document or just have a look here:
Byte 1-2: Item ID
Byte 3-4: Level, Option(0-12), Luck, Skill
Byte 5-6: Durability
Byte 7-14: SN
Byte 15-16: Excellent Opts, Additional Option(12~28)
Byte 17-18: Ancient Data
Byte 19-20: Item Index
Byte 21-32: Blank Zero data

there is now "17 byte" for the simple reason that it cannot exist. The minimum length of a binary string is "FF" (2 varchar symbols which is equal to 1varbin string)

The item id and item index are the same as the once in item(kor).txt with a minor differences in the types (12,13 and 14) and four of the shields (Legendary, Chaos and two more i don't remember at this time)

further more the excellent options coding are not correct (in your doc file)
00 = not excellent
01 = Increase Zen +40%
02 = Defense Success rate +10%
04 = Reflect Damage +5%
08 = Damage Decrease +4%
10 = Increase Mana +4%
20 = Increase HP +4%
<- NOT !

Correct ->
01 = Increase Zen +40%
02 = Defense Success rate +10%
04 = Reflect Damage +5%
08 = Damage Decrease +4%
16 = Increase Mana +4%
32 = Increase HP +4%


Also the level byte is calculated by (ItemLevel*8)
The item type is calculated by (ItemIndex*16)
And the skill adds 128 to the value , not 8

about people wondering how to convert int into binary here's the function's u'll need to do it (php and mssql)

php:

//Int -> Bin
sprintf("%02X", $INTVALUE, 00);
//Bin -> Int
hexdec(bin2hex($BinaryValue));

mssql:

-- For Int -> Bin
cast(IntValue as varbinary(1))
OR 
convert(varbinary(1), Int Value);

-- For Bin>Int
cast(IntValue as int)
OR 
convert(int, Bin Value);

Re: [Guide] Understand hex code for items 1.02Q

If you woulf read carefully, you would have noticed, that I wrote: Calculate in hex ^^
So, where is the point??
If you would check the items in the db, you would see that i.e. exc. opt. Increase HP 4% is stored as "20" of course in hex!
The items are stored in hex NOT in dec. This causes confusion to most pelople...
And why converting to dec. and then reconverting to hex...???
Anyway, thx for your comments and the php adds.

I don't see the point of working in hex when its item kor is in txt and its easy to decode it by a simple formula in int..but nvm, its my opinion, you have yours..

Re: [Guide] Understand hex code for items 1.02Q

Don't get me wrong. I really appreciate your post, because it shows a different point of view, and we all can learn from that.
Why I dont want to convert in dec?
Simple: in hex I have simple additions, without passing through conversion and reconversion with multiplying, and at least what for me counts, are the values in the db and they are in hex.:sweatdrop

I'm not I'm not getting it all (maybe i'm retarded, happens)
can you explain how will you cr8 an item like this (step by step)

Mace +12+20+skill+luck+excellent damage+hp/kill

Re: [Guide] Understand hex code for items 1.02Q

Byte 21-32: Blank Zero data

Maybe this can be a space for Jewel of Harmony options.

Re: [Guide] Understand hex code for items 1.02Q

Item options are wrong. To make +4 to +16 and +20 to +28 options you should add 01h-03h to 03-04 bytes. But the difference for options larger than +16 is in 40h item in 15-16 bytes. There are some more pitfalls in items codes, but it's easy to find and understand them.

Mace +12+20+skill+luck+excellent damage+hp/kill

01-02: 40h
03-04: 08h*Ch=60h (+12lvl) + 04h (+luck) + 80h (+skill) + 01h (+20 opt [see also 14-15 bytes C0h value]) = E5h
05-06: 00h (durability)
07-14: 00h (serial)
15-16: 40h (+opt > +16) + 20h (+excellent dmg) + 02h (+hp/kill) = 62h
17-20: 00h

Result: 40E50000000000620000

this is the result of the item......
i would guess yours is a season I item code..but still the 2nd hex couple is not correct.

For S2 code is: 00E50000000000620020000000000000
Check it in CzF Editor 1.5. So E5h is correct code and E1h is code for item without luck.

yep, my bad..just checked it w/ my editor o.0... i rly forgot to put luck on the item i though i didn't writedown luck ^_^

You are absolutely right! I was not carefully enough with the options.

Nope. You wrote in doc that you add 04h to 15-16 bytes for options larger than +16. But you should add 40h. It was a first mistake. The second mistake: codes at 01-02 positions are not unique. Check it yourself. For example look at Divine Sword of Archangel and Divine Armor. Both of them have 13h in 01-02 bytes. So the difference between the same codes at these positions is in 80h item in 15-16 bytes.

2 things:
1) you might got the wrong document. During the upload I had some troubles, so I decided to upload the document to my forum and I realized that I had switched the numbers 40 to 04 but I changed that immediately. You were to fast with downloading ^^

2) The items in byte 0 are o course "unique". You will identify an item with 2 bytes: First byte 9, the item index, which you will also find in your item(kor).txt as the first and single number at the beginning of each group (8 for example for armors) - and, second byte 0, the item type, which is the first column in your item(kor).txt.

Just take any editor and check yourself. As I said AA sword and Divine armor. They both have 13h in 01-02 bytes.

Re: [Guide] Understand hex code for items 1.02Q

You do not understand me. When I'm talking about bytes I do not mean computer bytes but positions of hexademical codes in full item code. And I mean only S1 codes. Look at this:

Position:                 [COLOR=Green]01 02[/COLOR] 03 04 05 06 07 08 09 10 11 12 13 14 [COLOR=Red]15 16[/COLOR] 17 18 19 20
Divine Armor:              1  3  0  0  0  0  0  0  0  0  0  0  0  0  8  0  0  0  0  0
Divine Sword of Archangel: 1  3  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0

It's for S1! There is nothing to do with your 9th byte in S1. But for S2 you are right.

Not true, when the item category is over 6 or 7 (maybe even 5,8 not sure) it automatically increases the 9th bit with 128 (dec) and 80h hex, thats whats the difference between the divine armor and divine sword of aa.
In season II the 9th bit is led to the pure item category (instead of all itemid and cat. being all in one bit, they made it better) and it is..
btw i'm kind of confused now..for season I wasn't it the 8th bit or was it then 9th? Em..

Re: [Guide] Understand hex code for items 1.02Q

Themad is right. And there are some ugly "side effects" when you are using S2 items with type > 31! Byte 3 (pos. 7-8) get corrupted, because it will be overwritten with hF9. I am not sure if today any server or client can handle this.
I remember, when those servers were released, we had those "Bronze Armor" effect, when the armor with item type 32 became bronze, 33 dragon ^^.
Fen$x had patch for this problem. But you had to do this with ollydebug during the run time of the server, which is really just for freaks...

See attached the Itemhex Code for items with length 20.
