Re: [Flightgear-devel] Re: Multiplayer Server RFC -- Current Status
I have an account with DMSO so access to HLA is not a problem, distributing it probably is ;) Database interface, what I would love to see would be a 'common' interface (base class maybe?) that the server sees (so it will have the basic get, put etc etc, the implementation of the actual db specific interface is then derived from this (maybe a design pattern would surfice?), this would allow any type of DB to be used at your leisure. I am not sure about combat, but what I would love to see is the number of ground vehicles (taxing and on the runway) change depending on the time of day Does Flightgear have a plugin type system? If not would that make a nice feature to add? Combat items such as guns could be a plugin? Want to chat instantly with your online friends? Get the FREE Yahoo!

Re: [Flightgear-devel] Multiplayer Server RFC
Hiya, since the inclusion of prior e-mails is starting to make for a long message, I will make my points about the previous message in bullet points: 1) I have a fairly extensive PhP knowledge, which will come in handy. 2) I agree it would be a good idea for you to design the protocol, I would recommend reviewing the DIS and HLA protocols to see how they work, HLA especially is actually powerful. 3) Thinking about the interface, I would like to see the main scenario server application run/configured through a web interface, I also like the suggestion that you download a scenario onto the server. A graphical scenario editor could be a nice tool to eventually build? 4) An SQL database is needed to store information (My preference is Mysql++) 5) I did not mean to imply I would be doing all the internals, sorry if it came across like that, I would like to get involved more into the really nitty gritty scenario management side (including interpolating and dead reconing) since I have an interest in that. 6) Al West has started to put a website together for cumulas (http://www.aurora-solutions.co.uk/~cumulas/), which is where I was going to put design notes etc, if people agree?

Also, it would be interesting to be able to download the scenario to a file for use with a local server, or for upload to a remote server via the web interface.

I can host the php and web interface on my company server, but before I make any attempts to port it to it to flightgear I wanted to get gauge peoples thoughts on it?

I agree that there should be a primative gaming system, I sometimes play sturmovik which is me and a mate alone.

In my opinion I would go for a set of official servers that are centrally managed and people connect to create a 'world' and then private run servers for personal use. As for the monitor, what I was considering was a tool that connects to a network port on the server which dumps data to allow you to see network traffic, maybe call it trafmon?

I think we should still be able to have a primitive multiplayer code built in fgfs game or the better idea, to optimize the server as most as possible, to be able to run with fgfs smoothly. btw. We could also implement into a server program you to be able to view the current status of aircrafts/units in the air (pure text mode, dumping into a file/screen), so you could be able to look at the current status with some external programs.

Re: [Flightgear-devel] Dynamic Scenario's
Hi David, I have been reviewing the current situation, I am not here to try to take over and start redoing stuff, BUT what I am proposing is a radical change to what is men't by Dynamic Scenario. As said when I first joined in, I work for a very large flight simulation company, where we have a dynamic flight simulation server. I know there are two concerns with having a server: 1) Communicating with the main system (latency) 2) Some peopele don't have ethernet connections thus how will it work on a stand-alone machine (like a laptop). My proposal solution to the above questions are that we use shared memory or ethernet communications (user selectable), the main flight-gear app will not really contain the AI code, it will be done by the server, which updates lat, long, altitude, heading etc, this is sent to flight-gear that then does the displaying, sounds etc. The server (dynamic scenario) could then be used to manage plane routes, knowledge bases for the flight dynamics etc. comments? Paul - Original Message - From: David Luff [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, February 10, 2003 11:46 AM Subject: Re: [Flightgear-devel] Dynamic Scenario's Hi Paul, As others have pointed out, there has been a small amount of AI traffic development going on, and as the guilty party I'd better pipe up sooner rather than later :-) I'll describe what I've been doing and leave it up to you whether you want to join in with that or start afresh. I've started from the premise that if there's going to be a number of planes in the sky at once, then they should take up as few CPU cycles each as possible. Hence my vision is for very simplified mechanics of flying - basically known ranges of speed, bank, climb etc for a given flight condition, and a bit of smoothing of transitions in between. Also only very near AI planes to the viewer to be updated every frame, the rest to be updated 1 per frame, and hence robust to variable times between updating. I'm pretty sure that not everyone agrees with that, and that some would go for coupled autopilot/fdms flying the planes as if they were another user-fidelity flight-model, but the simplified route is the one I started down. Then my basic structure is that an AI manager iterates through a list of AIEntity classes, and updates one per frame. The AIEntity has the minimum logic necessary to be drawn on the screen, and progressivly more complex classes are derived from it - for instance a plane that can taxi, then a light plane that can fly circuits could be derived from that and would already know how to taxi, and then a light plane that flys from one airport to another could be derived from that and would already know how to fly circuits and taxi. Having said all that, I've basically hardly started! I've got one hardwired AI plane in so far, that can be seen by starting FlightGear with: fgfs --airport-id=KEMT --prop:/sim/ai-traffic/enabled=true --prop:/radios/comm/frequencies/selected-mhz[0]=121.2 --heading=10 You do need to download the w120n30 scenery block as well. This will start you at El Monte behind a light single (no, NOT cheese!!!) that takes off, flys a circuit, and then taxis back to a parking spot. It's great fun to try following it round. You can make it fly touch and go's by changing line 54 in AIMgr.cxx: local_traffic-FlyCircuits(1, true); to a larger value than 1. The limit of my ambition at the moment is to get light planes taxiing in and out of and flying circuits around GA airports at the moment. This is a huge amount of work in itself - particularly the taxiing part, which also involves writing an infrastructure to describe logical taxiway and parking networks at airports, and tools to allow users to create/modify them. There's absolutely no way I'm going to get time to do any planes that fly from one airport to another in the next year or so. Anyway, the nub of the matter is that you can either join in with what's started, where the best separation of work is probably to go for planes that fly from one airport to another, or start afresh if you think I'm on the wrong track. If you start afresh bear in mind you'll need some communication with the ATC system - both to send and recieve messages. Interactive communication with tower control (You are number 2, extend downwind for traffic on straight in / go-around I repeat go-around / cleared to land etc) should be comming quite soon and you'll need to respond to those. If you do you're own taxiing system then communication with ground control (in a programming logic sort of way rather than spoken transmission) is a right can of worms since we need to communicate a logical representation of a path to follow to and from tower and plane.
