well, why don't you give away metamod with your bot ? so that metamod is installed with the bot, unless it finds a newer version of the metamod DLL already installed... should be simple, open liblist.gam, and check whether the file that's declared with gamedll exists, and if it's metamod, and whether its a newer version or not. If it is, just add a line in the plugins.ini to point to the bot DLL. If not, install metamod
And YES, metamod DOES update very quickly, actually it's the FIRST thing that is updated everytime there's an engine change, because EVERYTHING depends upon it, be it AdminMod, StatsMe, AMX, Cheating-Death, HLStats, W3 Mod, and the myriad of plugins for either of those. How many public servers out there DO NOT run metamod? I'd bet less than 5 percent. Metamod HAS to be up to date, and Will Day is in the best position relatively to the officials at Valve to smell any change in the air. Much better than any of us. As I said once, metamod's popularity can guarantee our bot's viability.
