It seems that 1.66 changed something about the bodypart offsets. A script, that I used to force-attach wings to RDDs>lvl 9 stopped working correctly after the update.

Any suggestions?

I think Bioware has removed the ability to change PC data in-memory, which is what SetBodyPart was doing. It seems this function still works for NPCs, just not PCs.

Hello Craig,

sorry for bothering you with a PM.
I have the impression, that with 1.66 you guys improved the protection of the player character's memory objects. Probably to restrict mem-edit based cheats and hacks on client for servervaults.

I used a serverbased NWNX fuction, to force wings on RDD players, who edited them out with Leto. You know, those who want the stats, but not the look. This doesn't work any longer with 1.66.

I don't critize this or would call this a broken fuctionality. I can rather understand it, if the reasoning is as I asume. I just would like you to confirm this, so that I don't waste too much time on trying to fix something, that can't be fixed.

Thanks in advance,
Michael


We did not make any changes with regards to RDD wings in the 1.66 update (or to the player's object in memory with regards to RDD wings).

If your NWNX stuff is no longer working for RDD wings, I suspect it is an unintended byproduct of some other change that we made. Possibly the addition of the new Get/SetFootStepType scripting commands have changed the format of the player update objects in memory (or possibly it was caused by some other change, although I'm not sure what that would have been).

Not sure how much help that is.
Craig.


Well, it seems I was totally wrong with my asumption, allthough it made sense to me. Razz
However, Craig's reply gives at least some hope for a solution.

That's right, it's working again. After spending ages (About an hour) trying to find the new offset I was finally lucky.

The old info from my old topic:
Dazzle wrote:
Just a custom functions.dll I once compiled for my own use.

Contents:
void NWNX_SetGoldPieceValue(object oObject, int iValue);
void NWNX_SetTag(object oObject, string sValue);
string NWNX_GetDescription(object oObject);
void NWNX_SetDescription_(object oObject, string sValue);
void NWNX_SetName(object oObject, string sValue);
int NWNX_GetBodyPart(object oPlayer, int nPart);
void NWNX_SetBodyPart(object oPlayer, int nPart, int nType);

Credits go out to Isilweo for the SetName and SetDescription and the NWNX Team for the other functions.

These functions only work with the Windows version of NWNX. It has not been tested on Linux.


The new DLL can can be found here (I added the source too this time!).

For those wondering, the new offset is +12 bytes (I have no idea if I'm saying this correct, I'm a newbie programmer Razz )

Enjoy.

Edit: Rar file updated due to typo in the source causing GetBodyPart not to function.

Thanks Dazzle.

The changes in 1.66 obviously moved the memory locations for the bodyparts 12 bytes off. The changed and recompiled DLL allows to get it back working without any script changes. Tested and implemented.

Yeah, thanks alot. I tried using OBJDUMP to figure it out myself but somehow it didn't work... Anyway, I made the change on Linux and it worked. ^^ Kudos.

I don't see any changes in the downloads. The windows download source doesn't even have the Get/SetBodyPart functions. :S

The source is part of the Linux NWNX2 download. I just updated the offset used only in Set/GetBodyPart and recompiled with Redhat Linux on i386: http://www.antiworld.biz/downloads/nwnx_functions.rar

Could you post the function the script uses to change the wing on the PC? Especially the one with the SetLocalString() function.

Hmm.

Change these two functions:

Code:
int GetBodyPart(object oTgt, int nPart)
{
    SetLocalString(oTgt,"NWNX!FUNCTIONS!GETBODYPART",
        IntToString(nPart));
    string sType = GetLocalString(oTgt,"NWNX!FUNCTIONS!GETBODYPART");
    return StringToInt(sType);
}

void SetBodyPart(object oTgt, int nPart, int nType)
{
    SetLocalString(oTgt,"NWNX!FUNCTIONS!SETBODYPART",
        IntToString(nPart)+"!"+IntToString(nType));
}


To:

Code:
int GetBodyPart(object oTgt, int nPart)
{
    SetLocalString(oTgt,"NWNX!FUNCTIONS!GETBODYPART",
        IntToString(nPart));
    string sType = GetLocalString(oTgt,"NWNX!FUNCTIONS!GETBODYPART");
    DeleteLocalString(oTgt, "NWNX!FUNCTIONS!GETBODYPART");
    return StringToInt(sType);
}

void SetBodyPart(object oTgt, int nPart, int nType)
{
    SetLocalString(oTgt,"NWNX!FUNCTIONS!SETBODYPART",
        IntToString(nPart)+"!"+IntToString(nType));
    DeleteLocalString(oTgt, "NWNX!FUNCTIONS!SETBODYPART");
}


It should be fixed now, I remember having the same issues, took me a while to figure it out.
