Please someone answer my question......

Can I play DoomBot not only in ZDoom,but also in ZDoomGL?If it can.So how to do it?
Which Bot of Doom is the best?
Where I can find more TC for ZDoomGL?
Thanks.

nope, if DoomBot uses zdoom, DoomBot will not work with ZDoomGL :o(

as for the best one i don't know, but i've had alot of fun playing against the bots in kulltag (allso based on zdoom), as that port allso is specially aimed at multiplayer i'd suppose it is atleast one of the best :o)

most tc:s (appart from the one's using the edge engine) can be played under zdoom, as zdoom (and therefor zdoomGl too) is fully boom compatible.

although, i only know of one tc yet specially made for ZdoomGl (zanzan).
