nwnx_structs plugin for Linux (updated to version 2.1)

This plugin allows reading and manipulation of values not normally exposed in engine structures. Right now it supports Effect and Item Property structures.

Good work.
I think that it isn't very funky to hook the middle of the function, though.

[acaos]

Yes, that's a really ugly place to put it.

From what I could determine, that entire function I hooked is used to push and copy variables before a function call. I didn't want to hook anything but the effects part, so other variable types would not be slowed down at all.

I'm still looking for a better place to stick it. There's a call right after, but it's a computed call and can go to several different places.

I've updated the plugin to v1.1. This adds GetEffectInteger() and SetEffectInteger().

The indices to use depend on the specific effect type. You'll need to play around to find out what's what. The index is limited to between 0 and 15 as a safety measure to prevent poking too deep into memory.

Another update, this one to 1.2.

This adds the ability to get the duration of an effect as well as the remaining time on the effect.

The CalculateEffectDurationBasis() function must be called before calling GetEffectDurationRemaining(), targeting a creature or player. It only needs to be called once. I haven't yet managed to dig out the internal uptime timer, so this does a bit of a song and dance to determine that.

Updated to version 2.0.

Plugin renamed to nwnx_structs.

This renames CalculateEffectDurationBasis() to CalculateStructDurationBasis().

Adds support for reading and manipulation of values in item property structures.

I've updated the link to make this accessible again.

Also, I received a recent request via PM about effect icons. Although this version of structs does not support it, NWNeXalt, my new 1.69 NWNX plugin, does have an EffectIcon() function which displays icons from the effecticons.2da file.

EffectBonusFeat prevents the use of horse menu from patch 1.69.

You need to actually edit the client executable to add new effect icons, unfortunately. Here's the necessary hex editing (from our client patch on HG):

Windows Version
- This version of the client changes byte 0x15476C from 0x82 to 0xFE. This raises the limit on effect icons from 129 to 254.

Linux Version
- This version of the client changes byte 0x07B9CA from 0x81 to 0xFE. This raises the limit on effect icons from 129 to 254.

To be specific: the SetEffectCreator and SetEffectSpellId works, but only inside the script which modified it. When i check the spellId from other scripts, the ID returns the original value :S

[virusman]

nwnx_structs manipulates the local copies of effect structs stored in local variables. To apply these changes, you have to re-apply the effect.

I'm trying to make a version of the iprp functions for windows, but I suck at reading bytecode, nor do I have a linux executable...

Does "8B 46 10 8B 7D 0C 8B 4A 08 FF 34 B8 0F BE 04 1F" (from the signature search function of nwnx_structs) equal StackPushEngineStructure?

[virusman]

No, it's in the middle of CVirtualMachineStack::AssignLocationToLocation.
