I'm a little confused about the custom sounds for Hudguns;
I've noticed that it's either command registersound or altsound followed by the directory followed by a designation number (most likely the sound volume???)
Also stated in sounds.cfg: "hardcoded cube sounds (i.e. order matters, and these must always be the first to be registered)"
So just trying to play a my custom sound for the rifle when using mr.fixit playermodel, here's what I have so far:
_{if (= $playermodel = 0) [
registersound "q009/rifle" 80 // "awesund/rifle" //"free/rifle1"
altsound "q009/rifle2" 80
altsound "q009/rifle3" altsound "pyccna/mrfixit/rifle" 80]}

So I'm actually wondering now: is it possible to change the hudgun sounds without modifying the source code, if so how should I go about doing that?

I wonder how to name a base for capture mode in a custom map.

I've seens maps with waterfalls that curve/ bend... I'm curious on how they did that, and if it's possible for me to do it. Same thing with lava. Also I've seen maps with glass slopes.
