ok so I have successfully hacked barney such that he now only attacks the red team in tfc (or whatever team 2 is in other mods). A skinner at my community is working on changing otis to serve as the red team counterpart to barney (attack the blue team or team 1 for other mods). He is still tinkering but here is what he came up with so far.
of course I'll go ahead and whip up a nuetral barney if you still wanted that as well... And I might go forward and try to get versions for the other 2 teams supported by the hl engine too and maybe even do a hgrunt version of the same. For othe mods diff models may be needed to match team colors (ie dod is green and red teams). But so far so good...
