It's not about UT469.
RX mod has different rules. Common Bot is not 100% good at these "flight" capabilities. A few things must be added in a potential RX Bot which should be integrated in RX package recognizing what to do after spawn. This is not a very must be thing because... first I want to see how many mappers are capable to develop flying maps.
If you look around, some of them are mindless full time at doing NORMAL paths - after 20 years of UT
. And the rest are clapping hands at craps like these are uber duber maps, lying themselves. For these people if a map can be started in a server it's just "great" - great garbage in reality. I cannot expect magic from those which are never understanding normal Engine physics rules, for flying chapter, things are a bit more complex...
R_Fly required flag in normal plain Editor is Never added. Here we can do some fake swim routes for common mapping or simply stepping in XXI century with UGold editing or XC paths adjusted. Who knows to work with these ?
