Urban Terror Forums: Messing with bot settings - Urban Terror Forums

I run a server with bots on it, and I've been messing with the following settings. I barely know what they do, so maybe some people could tell me what advantages/disadvantages there are to messing with these... I know I "should not mess with those" but a lot of maps have poor bot support and I am extremely curious.

bot_testclusters
bot_testsolid

bot_aasoptimize
bot_forceclustering
bot_forcereachability
bot_forcewrite
bot_saveroutingcache

I set the following and went through all the maps and let it do whatever it does to them, and found that the .aas files for most of the maps were a LOT smaller after doing this than they were originally (as they came in the .pk3) is that good or bad?

bot_aasoptimize 1
bot_forceclustering 1
bot_forcereachability 1
bot_forcewrite 1
bot_saveroutingcache 0

And where does it save the "routing cache"? Cause I don't really see any new files...

Thanks for any info.
