What Silver said, I am baffled and sadden by this. This plugin is REALLY the best one I use so far, aside from the Bot Improver on the Workshop.

ReadMe states: Project is currently (mostly) unmaintained

FWIW, I occasionally get exceptions, but I do not get any crashes or stutters. It is the best bot AI improvement plugin I have found for dedicated servers and I will continue to use it. Of course, I would like to see performance optimizations since it uses a lot of system resources.

Hopefully the author updates it eventually or someone who knows how to code. This plugin is really nice and one of the best.

Seems like that this plugin is not compatible with ABM.

What gives it away?

Report a bug:
When player is down with a melee in hand, engine would replace player's melee into pistol. At the same time, if a bot without melee in hand near by player, and melees in survivor team is less than 'l4d2_improvedbots_melee_max_team', here bug comes that the bot will take the incapped player's melee, after player revived, he will lose his second weapon with nothing in second weapon slot.

Did some tinkering with the code, and I think the reason for massive lag spikes is the way how this plugin calculates distance to stuff

In a lot of places, there is a code that looks like this:

PHP Code:

    for (; LBI_GetNavAreaParent(iArea); iArea = LBI_GetNavAreaParent(iArea))
    {
        LBI_GetClosestPointOnNavArea(LBI_GetNavAreaParent(iArea), fGoalPos, fParentCenter);
        LBI_GetClosestPointOnNavArea(iArea, fGoalPos, fClosePoint);
        fDistance += GetVectorDistance(fClosePoint, fParentCenter, bSquared);
    } 


I'm not sure how one can calculate distance just by picking a "parent" navigation area over and over. Maybe it's just me; after all, Source SDK has the similar code. Point is, sometimes it goes runaway, and gives irrelevant high value.

Using L4D2_NavAreaBuildPath() without distance limit seems to cause lag too; especially if target is unreachable or nav_blocked.

Code (algorithm?) needs to be changed: whenever (wherever) you calculate distance to an entity, and result is a failure, mark the entity as un-pathable and don't try to calculate path to or from it ever again, at least for a duration of this frame. Don't kill the server by trying to reach the same stuck/out of bounds zombie for each survivor bot etc.

I attempted to do something like this in a fork of mine, but there is just too many places in code where "distance to object" is called/measured ever so slightly different, and i'm not finding and fixing all this sh

Feel free to check out the fork on github. Compile the sp file.

Fixed that behavior as well.

It'd be great if someone knowledgeable (@silvers?) looked into changes and gave advice where possible. Kinda new to this plugin thing.

That's the issue with "VScript" plugin, guess someone has to let the author know that they use same names in their code.

I'll put compiled file on github when I sort some stuff out with the code.

I do not know what plugin put that vscript.inc file there, but I do not have it and can compile this plugin just fine, using either the source posted in the original post or pulling it from the Emana202 github.

Nevermind, I see that was added in the modified version by Kerouha.

Can you add some features to make survivor bots able to avoid from special infected?
