The best way to start is by looking at and tweaking some of the values to see what they do. Try tweaking gravity a little first.

Yes, but what is "auto getting map in ffa* mode"?

It's that old story (see "Most Wanted Features" thread and diverse other places) of not having to do "/getmap" ...
But what this has to do with trick-jumping baffles me.

Anyway, what is the server supposed to do differently than the regular sauer-server?

Is this supposed to be a server-side-only MOD - which I strongly suspect it isn't.

More information would be required at least to judge the help you're expecting ... and maybe you should read the latest topic on the forum too : http://cubeengine.com/forum.php4?action=display_thread&thread_id=1562

"auto getting map in ffa* mode" is atomaticaly sending map and player's downloading it...

Mmmh. ... so what's wrong with
- publishing maps on quadropolis
- grabbing a server and voting/mastermode-ing to FFA and loading your map

...and telling players to read the console if they don't "/getmap" ...

Not currently possible, and for good reason.

It could be implemented easily client-side, but I don't know how many people would be willing to open a hole in their security just for an automatic /getmap.

oh - before you tell us that there's no "/getmap" or "/sendmap" in FFA ... well - that's what quadropolis is for on the one hand and a quick change into coop-edit and back to FFA once people have your map can't be that bad - if you really want to get some fun/feedback.

Also - you /do know/ that there's no CFG-file sending/getting ... in short: only OGZ is sent during get-/sendmap

I'd love to see an auto-getmap function but I don't think Sauer is capable of implementing such a feature without significant changes/improvements.

I would help if I had the will power, but to put it bluntly, it would be a massive headache with my current knowledge and tolerance of sauer's source code.

Oh, an auto-getmap would be pretty simple. Just perform a getmap on connect (or only if the server says there is a map to be gotten).

However, as MeatROme and I have kind of said, an auto-getmap is a bad idea.
A malicious user could go into a server, send a corrupt or specially-crafted OGZ, and wait for people to connect. As soon as they connect, bam, gone.

See? Bad idea.

It\'s simple, you only need to allow in fpsgame/fpsserver.h the sendmap command in all mode\'s and you need to add by clientconnect

-> clientconnect

if(mapdata)
{
sendf(ci->clientnum, 1, \"ris\", SV_SERVMSG, \"server sending map...\");
sendfile(ci->clientnum, 2, mapdata, \"ri\", SV_SENDMAP);
}

and by sendmap (void receivefile(int sender, uchar *data, int len))

remove the \"gamemode != 1 ||\"

BUT: i don\'t know if that is working .. cause i think the client is proofing if it\'s coop...

I mean a getmap function that sends everything needed to run a map - CFG file, textures, sounds etc. The malicious user sending a corrupted/crafted OGZ file is a poor excuse, the OGZ file reader should be rock solid anyway, can sauer not detect maps with exceeded limits or something? I have no understanding in this area. No, the security risk that comes to mind is the map CFG file, a malicious user could overwrite configs or run an infinite loop. The scripting language needs to be sandboxed and a (full) file transfer service needs to be implemented, both potentially significant work.

Think, how do other games do it? Now do you see? :)

Umm... I can't think of any other games that provide content in that manner.

However, you are right, the CFG is also a risk.

You say that scripting "needs" to be sandboxed and that a full file transfer service "needs" to be implemented...
Well, you've got the source, you're free to do it. eihrul (and others) won't (and can't) implement every suggestion made.
Sauer is open-source--make it happen, maybe it will become part of the whole.

@#18

I know for sure CS:Source does it :D

Yes it's open source, but "it would be a massive headache with my current [lack of] knowledge and tolerance of sauer's source code."

Quoting #17:
"The malicious user sending a corrupted/crafted OGZ file is a poor excuse, the OGZ file reader should be rock solid anyway, can sauer not detect maps with exceeded limits or something? I have no understanding in this area."

It's nothing to do with detecting bad maps. If there are *any* bugs in the map loading/parsing code (hint: all code has bugs) there is the potential for a security breach on the client. This can be exploited by carefully crafting the aforementioned "specially crafted OGZ".

And yes, the problem is exacerbated with config files.
