Project-O is what you want. It is open source with HTTP reachable via LSL scripts that use local host.
It uses WAMP or LAMP and php with low impact.
What it adds to your NPCs is real AIML backend chat and functions you can embed codes to trigger your npcs with depending on the replies (use basic ALICE set) to start.
Start here
https://program-o.com/then
https://github.com/Program-O/Program-O/tree/devSet it up as it says (real easy) btw.
just keep it all local host since we arnt using it like a web page here but you can to both.
I already have LSL scripts that work great interfacing my NPCs to program-o (opensource btw).
I will post a few examples after you have the basics set up.
But this is the good stuff and mort (dev of project-o) is great.
They just have no idea how cool what they have is for 3d spaces.
Anyway i will post more about the how to later.
NPCS get real AI, god help us all! lol
This lets you put your NPCs into the very real AIML A.L.I.C.E world and that has its own learning curve where the idea is to have AI talk and act as human as a computer can.
As you can use program-o to make it how you like, your AIML set can be done to talk about and know about and learn about your idea (your 3d space).
I will not go into that, Just about how you can hook it into your mad dream within your own region.
And no it will not effect anything as far as the grid goes because it becomes a sub system as backend to just your sim.
Anyway take a look and ask alot of questions here and there but it is the good stuff !
tnx (more to come)
