Decoding NWN memory - Part 3 - Items

[isilweo]

Welcome to Part 3 of decoding memory series ;)
i hope you don't think i'll everyday post new discoveries about nwn memory (as i am just translating them from polish)

Below is items memory copied from ram. it's filed with my notes. there'are few item types in this memory piece cause i update it when i find new info with item part.

There is one important thing about offsets. It's also very strange. Normally when requesting nwnx function the gameObject pointer is set to first byte of object structure. There is an array with object ids and pointers somewhere in memory (maybe i'll write about it in next post) - pointers from that array points to same address as nwnx gameObject. So we can asume that that address (gameObject) is begining of object structure. And it is true for all objects but items. Items starts 0x10 bytes earlier!
There is also array with objects tags (and pointers to objects). Elements in that array also point to gameObject...all except items. Pointer to items from this tag_array points not to gameObject but 0x10 bytes before. That 0x10 bytes before are quite important cause info about color of weapons is stored there.

short legend:
unknown pointers are stars
zeros are replaced by - (minuses)

also we can write offsets using structures that we know

0x4 - SItemColors
0xC - basetype (int)
0x14 - Object ID (int) - the same that is ObjectToString()
0x18 - object type (byte)
0x28 - SNWString ItemTag
0x30 - SNWString ResRef (int)
0x84 - Area ID (float) - it is "where am i laying"
0x88 - Xposition (float)
0x8C - YPosition (float)
0x90 - ZPosition (float)
0x94 - XOrientatin (float)
0x98 - YOrientation (float)
0xE0 - Plot flag (byte)
0xE8 - SLocalVarsPtr localvars
0xF8 - pointer to array of pointers to (int - efect_id)
0xFC - number of elements in array from 0xf8
0x1E0 - identified flag (byte)
0x1E8 - properties 1 pointer (active?)
0x1Ec - properties 1 count
0x1F4 - properties 2 pointer (passive?)
0x1F8 - properties 2 count
0x200 - charges (byte)
0x204 - cost (int)
0x20C - addcost (int)
0x214 - SItemModels
0x238 - CExoLocString DescIdentified
0x240 - CExoLocString DescUnidentified
0x248 - CExoLocString name;
0x25C -cursed flag = non drop (bytE)
0x260 - stacksize (word (czyli 2 bajty))
0x264 - stolen flag (byte)
