to anwser your questions
1) bots can change weapons overtime i don't think you can make them change their weapons ingame but can do in slade
2) their main weapon is their first weapon however having a second weapon can be good but requires this acs code
if (StrICmp(botName, "fakeman") == 0) { GiveInventory("PoliceBunbyWep", 1); } example of fakeman from mm9
3) did you use the mm11skins from painkiller you might have to reinstall it

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
it is finally ready and it's released to you all thank you for waiting
if you still have all the mods from the first post i wrote
then get ready for another skirmish bot mod i made along the way
as this is no joke this one requires the same wep mods you saw on the first post
p.s don't use allanxwepsv3c use v3bh instead cause i have not got a new version and the bots don't come with the new weps sorry

quick update
i'm gonna start creating weaknesses for all bots in this mod
it's for the next upcoming version of this mod so stay tuned
however i'm not gonna create weaknesses for mmd and mmrf skirmish bots
right now at this time so as i said stay tuned for the next version
the reason is i don't know any of mmd & mmrf bots weaknesses
so i'll do more research when i have the time
but if you do know their weaknesses post here
anyways see you soon for the next version
bye =)

welcome to my first ever mod for mm8bdmv6b

mmrfweps [requires mmrf skins]
mmuweps

anyways i don't have anything else to say but have fun with it
