On the bright side, it seems that Curt's scenery build is more accurate to the real world. I've checked some positions for buildings on multimap.com and it does turn out correct on the flightgear.org scenery build, while with my build, the building apparently sits in the sea :) Pigeon. ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
[Flightgear-devel] Re: Re: [Terragear-devel] Land data differences?
Yeah... Also, the thing is I'm planning to create sceneries and models for Hong Kong, and possibly some Taiwan and Sydney. I found multimap pretty useful. I suppose I work on them based on FG's official sceneries. So, back to my original poblem, does anyone know what data is used for the FG official sceneries? And how? I would imagine there's some sort of automated scripts or something? I ended writing one or two simple shell scripts to do all the terragear stuff (tgvpf, fgfs-tools-server/client, the lot) too. > Hehe, the source of coordinates for buildings is a different one.

[Flightgear-devel] One bug with multiplayer...
Hi, I've been trying to track down a bug with sometimes players (aircrafts) not being shown even it's getting udp packets correctly. What I've found out so far is that if someone logs off, then whoever logins using the same aircraft model will simply not appear in fgfs (those who has got the logged off event). There could be something to do with the model loading and cleaning up code in MPPlayer::LoadModel() and MPPlayer::Close() in src/MultiPlayer/mpplayer.cxx? Unfortunately I don't know anything about simgear/plib... On a side note, while testing the multiplay mode, robitabu on #flightgear irc and I have discovered the "Instant Replay" is also sent to all other players. Kind of a nice "feature" when you want to show people stuff, but also probably something you don't want all the time... :) Pigeon. ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d

[Flightgear-devel] Re: One bug with multiplayer...
The bug is, after all, caused by SGModelLib::flush1 which is disabled/broken, as the warning (WARNGING: a disabled/broken routine has been called. This should be fixed!) and the comments in the code say. As a result the model is not reloaded as load_model() finds it in its list (_table). I'm wondering would it be worthwhile adding a method to SGModelLib to remove/unload one single model from its list? An unload_model() maybe? That way we don't need to walk the whole list in SGModelLib?

[Flightgear-devel] Re: suggestions/questions regarding multiplayer
Would it be good if both ATC and chat message could be in some sort of text area box so you have the history and you could scroll back and stuff? Also I'm wondering if the server should take control of who's logged on and off. At the moment the client is taking care of that by adding a player if it gets udp packets that it doesn't already know about, and removing player if it hasn't got anymore packets from a player with a timeout. I was thinking that way we could show logon/logoff message in the multiplay window. Now it's some sort of a multiplay event window, rather than only for chat messages. > 2) chat messages > The server (in fact every client) should be able to send messages to clients > which get displayed on the screen (i.e. the flightgear window), just like ATC > messages.

[Flightgear-devel] Re: suggestions/questions regarding multiplayer
Got a little further suggestion with the multiplayer. It's probably just a server side thing though. It might be worthwhile for the server to accept "observer" client. You can connect to the server as an observer, i.e. no aircraft. You get information about players online, where they are, etc. Could be useful for doing things like an online map on a webpage to show who's currently online and where they are on a graphical map. Would be cool when later atlas supports showing multiple aircrafts.

[Flightgear-devel] Re: Re: suggestions/questions regarding multiplayer
> So, basically you get an invisible UFO and don't show up as a player, right? Hmm I would imagine the server doesn't need to broadcast these observers to others. It's not an actual player. I suppose using an invisible aircraft would work now as an observer. If the server could handle something like if someone connecting with a callsign "observer", then it would simply send packets to the observer about other real players, but don't need to get another info from the observer itself, except, perhaps, logging on or off. That will also mean the server needs to be happy with multiple connection with the same callsign. So I'd say it might be better to just treat them as a special class of clients.

[Flightgear-devel] [PATCH] Re: SEGV with ATIS
Figured out the problem with ATIS voice. It's in SimGear with the
code for OpenAL/Alut 1.1, whereby with in sample_openal.cxx,
alutCreateBufferFromFile() does not give us the raw sound data, and
ATCVoice depends on it, which leaves the data and the data size
uninitialized.
The patch used alutLoadMemoryFromFile() instead, pretty much the new
version of the old deprecated alutLoadWAVFile().
Also someone might know a better, more portable way of converting an
ALfloat to an ALsizei. I'm simply casting it at the moment.
Thanks.
Pigeon.

[Flightgear-devel] Re: 0.9.9 scenery?
Speaking of scenery, there are still people from time to time having trouble installing new sceneries. (The whole Scenery/ vs Scenery/Terrain/ and Scenery/Objects/ issues). I think it's worthwhile updating the docs and the "getstart" guide with these details. It's quite well described at Franz's page: http://members.aon.at/mfranz/flightgear/flightgear-howto.html Another thing is a lot of people expect "scenery" to be scenery + 3d buildings/objects. While, when you download scenery from FG's site they are pretty much "terrain" only. It might be useful to emphasising these things in the docs as well.

[Flightgear-devel] Re: Options saving patches
I guess what Curt was saying is, him being the "release manager" of the project, has to find appropriate and free time do all the things for a release, which is fair enough and understandable. Perhaps we can have more people to help doing a release? Personally I've only witnessed one release of FG (0.9.9). And I don't know what's the policy of this whole project. But could anyone else share the workload of doing a release? Or it has to be Curt and Curt alone? If we can do releases at any time, then surely we would have more control on what we could put into a release? I think most people, especially developers, prefers figuring out a features list or goals for a release, and then work towards them. When these are done, then we might want to go for a one month or two months code freeze/bug fix/stabilising/testing, followed by the release. And perhaps we could figure out some sort of roadmap? > Look, rolling out a new release is a massive effort. We need to do a > release more than once a year.
