Files in Pk3 form can be placed directly into your ET/Fritzbot/ directory.
If you're savvy with Pk3's and Pakscape, etc - then you can pretty easily build this path and just copy/paste new waypoint files into a temporary pk3 to hold all new waypoints and fixes until the next version makes them official then simply delete the pk3 when the next FritzBot Patch (which generally will include them when possible) comes out.
This is more or less taken directly from the waypointing tutorial in the waypoint forum and my personal experience with my one or two little projects.
If you put the waypointing files into the separate Fritzbot directories, you must set "pure server" to "no" when you configure your host server OR put this command into your autoexec.cfg file: seta sv_pure "0"
Reason is that both RTCW and ET require that game files be in pk3 form. If you want to use individual folders, you have to be "impure." I ran into this when I first started playing Fritzbot, too.
Most likely you downloaded the waypoint files and the extensions turned into a .zip. It's recomended that you change the file extension back to pk3 by renaming it.
If you happened to take the zip file and extracted it to the fritzbot folder, the waypoints will only work if you type /sv_pure 0 in the console before loading the map.
Yes yes, thanks for reminding me gentlemen. I just had that very issue with my waypoints for projekt schwalbe back in Rtcw the other day - silly me, it already slipped my mind that the loose files will not read without sv_pure 0. Duh.
The waypoint file has a pk3 extension and it should be placed in the fritzbot directory of your ET installation. That`s the only thing I did. Do the bots work correctly on the default maps?
