A new NWNX plugin is available: NWNX Visibility.
Using this plugin you can override object visibility - globally (always visible/invisible by default) or per player.
NWNX Visibility 1.0

Another words, control over perceptions.
Possible uses: Create an Invisibility Power which makes you invisible ONLY to the target.
: Create a counter power, which renders you immune to the said invisibility effect. Eg - Prevents someone from going invisible to you.
One thing though, because the code uses an object array/list in c++, and it performs a test against each object I assume, to see if it matches the object in question, could this potentially cause performance issues, if the object list is left unmanaged.
Eg - Say for instance a bad scripter configures it to add ALL perceived objects to the list, and left it running for 2 days. Im assuming even after log offs etc, player objects will still be in the list, being tested against the requested object. More objects in the list -> more time required, albeit small time, to find the correct match.
Do you forsee this requiring some sort of management or cleanup function, to maintain the object list/array, or empty it after certain durations?
Note - Im still a noob at nwnx plugin creation, any chance of windows? hehe.
I have the location of the testobjectvisibility function here
CNWSMessage::TestObjectVisible - 0x004409F0
Im just not sure how to impliment your code on windows, because everyone has their own coding style, its hard to understand the code when bouncing between plugins.
Ive got no hope of creating my own plugin from scratch.
I have next to no c++ experience, only just taught myself how to add hooks via studying the Events plugin, although, your hook in visibility is bit more complex. hehe.
If im not mistaken, its a code cave method your using, is it not?
It sort of resembles what I understand of a code cave.
You have it set to redirect to another address, where you have your custom code in, then it performs the changed code, then it returns back to the 'almost' original location as if it had never left that subroutine, none the wiser that the subroutine result was changed mid flight. |

This is not actually a perception hook. Perception is used for both NPCs and PCs. Visibility is only checked for PCs.
I don't think it'll cause any noticeable performance issues whatsoever even if you add a lot of objects to the list.
I'll add Remove/Clear functions in later versions.
