Modifying Cre Spell Offsets and Counts in Weidu

[Bill Bisco]

How do you modify Cre Spell Offsets and Counts in Weidu?

 

I filled out the below for Weidu code based directly from the Vaues that Near Infinity gave me. Is there anything else that I need to do to get the proper spells Known and Memorized working when this CRE is viewed ingame?

 

WRITE_LONG 0x02a0 ~2d4 h~ // Known spells offset 4 (dword)

WRITE_LONG 0x02a4 19 // Known spells count 4 (dword)

WRITE_LONG 0x02a8 ~3b8 h~ // Spell memorization info offset 4 (dword)

WRITE_LONG 0x02ac 17 // Spell memorization info entries count 4 (dword)

WRITE_LONG 0x02b0 ~4c8 h~ // Memorized spells offset 4 (dword)

WRITE_LONG 0x02b4 9 // Memorized spells count 4 (dword)

EDIT:

I can't copy directly from NearInfinity. What do I need to do to get the above offsets working?

Thanks,

Bill

It's not working because 2f4 h represents the hex value 2f4. In WeiDU, you represent hex numbers with the 0x prefix, not the h suffix, so you would want 0x2f4 instead.

 

However, I'm not sure why you need to set any of these values. If you are copying a file that already has those values, nothing will change. And if you're copying a file that doesn't have those values, you're probably going to corrupt it if you aren't inserting/deleting bytes to match the changes.

Mike1072, Thank you very much for your reply. The original IWD Erevain is a Fighter and my mod will make him a Fighter/Mage/Thief by default. Later on, I'll add support to allow him to alternatively be a Fighter/Mage, Mage/Thief, Mage, Thief, and even his original Fighter class.

 

As such, I'll have to manage a lot of complexity. I would rather manage this via Weidu Code and the mod files only have with 1 CRE file rather than requiring the mod to have several CRE files pre-stored.

 

I will modify the code as you have suggested and try it out. I am only giving Erevain default BG2 spells. Is there anything else I need to be wary of?

 

Thanks,

 

Bill

Alright, I'm getting some errors. Help would be appreciated.

 

This link clearly says that 10 stands for Fighter/Mage/Thief

 

In my TP2 file here , I clearly write this in the code

 

WRITE_BYTE 0x0273 10 // Class (CLASS.IDS) 1 (byte)

 

The final file does not take my change:

 

 

It takes all of the other Numbers I modified: Proficiencies, Str, Dex, Con, Int, Wis, Cha, etc.

 

 

None of the Spells Known and Memorization Info was copied correctly.

 

It should be

 

 

but it ended up as:

 

 

 

Any help would be very welcome,

Are you trying to add spells to the .CRE? There are better ways:

COPY_EXISTING ~creature.cre~ ~override~
  ADD_KNOWN_SPELL ~spwi101~ #0 ~wizard~ // adds Grease to spellbook
  ADD_MEMORIZED_SPELL ~spwi101~ #0 ~wizard~ ( 2 ) // CRE now has 2 instances of Grease memorized
BUT_ONLY

The "#0" is important. It tells what spell level to add the spell at, with 0 being level 1 and 8 being level 9. If that differs from the spell's actual level then the spell will be non-functional.

The erevain.cre file you are copying over is a CRE V9.0 (IWD) file, not a CRE V1.0 (BG/BG2), so you weren't writing to the right offsets.

 

1) You should re-create Erevain in BG2 as a player character, then follow the steps to convert him to an NPC. Then you will have him as a CRE V1.0 file.

2) You should not be adjusting spell offsets or counts manually. If you need to change spells, use the WeiDU commands that will insert/delete the data and update the offsets and counts.

3) Unless you are planning on offering lots of customization for the player during installation, it would probably be a lot easier to create the X number of different versions of Erevain and then install whichever one the player chooses.

Thank you all, sincerely for the replies. I used subtledoctor's coding suggestion and that worked great. I changed CRE formats per Mike1072 and that worked.

 

There are apparently some minor color differences between the CRE file versions.
