Are the LUA AI scripts being used?

[caelum]

Are civilian.lua and alien.lua the full extent of the AI? or is the c code still doing some of it?

Now that I have compiled the dev version I was going to play around with the AI, I managed to get one of my soldiers stuck between two civilians last time I played it.

Afaik LUAai is NOT activated by default. Not sure though.

[Kildor]

You are need to enable cvar to activate LUA. Not sure about name of cvar though.

[Mattn]

the cvar is g_ailua - but be warned, it's not very performant right now (at least if you don't also activate sv_threads - which is still not 100% working)

if you want to work on the lua scripts, help is more than welcome on this side.

[caelum]

I am happy to work on the LUA scripts. It won't be until after I have finished struggling with the Blender import/export scripts though .

Is the idea to implement something like what the ai diagram that is in SVN currently outlines?

[Mattn]

yes - something like that - if you have improvements or other ideas. feel free to discuss them in the wiki

[caelum]

So is there any ability for civilians to carry weapons yet? I am assuming no at the moment, but thought I would ask .

I think I can live with the slowness as I test out the scripts, it will no doubt be easier if bugs from the sv_threads are not thrown into the mix.

Do you know why it performs so badly?

[Mattn]

civilians with weapons are not yet implemented in the c ai code nor in the lua scripts

it performs so bad because it looks like it does way to much traces (see gi.trace calls - maybe caching some of them for one frame would increase the speed already to an acceptable level) - the traces are mainly used to get to the next possible walkable position and to search for potential victims or hide spots.

... - the traces are mainly used to get to the next possible walkable position ...

I hope the LUAai does NOT do it's own pathfinding, but uses the routing table instead !?

[Mattn]

it uses the game lib callbacks like the c ai, too - yes

[caelum]

Sounds like I should look through it and see if I can increase the performance a bit before worrying about improving the AI. LUA looks easy enough to learn that if the speed of using it is acceptable then there will probably be a few people willing to play with them.

[Mattn]

i think we all would welcome help on this front.

[caelum]

Can't say how fast I will be able to look at it, otherwise I would be volunteering more , but I will see what I can do as I get spare time.

I will just keep posting on this thread as I need help or want to discuss something about it?
