MX Bikes Official Forum

It is possible to connect to a dedicated server to receive live race data.
The feature is off by default and must be enabled:
http://forum.mx-bikes.com/index.php?topic=197.0
Only 1 client can connect to the server.

Communication is made with UDP sockets and strings terminated with "\n".

Send "CONNECT" followed by the connection password ( empty string if no password ).
Reply:
OK -> connected
FULL -> another client is already connected
WRONGPASSWORD -> wrong password

Send "START", followed by two parameter strings to start receiving data.
First parameter: "0" or "1". If set to "1", the track centerline and the track position of the bikes are sent, too.
Second Parameter: "0", "1" or "2". If set to "1", contacts between bikes are sent. If set to "2", then contacts with walls are sent, too.

Data format is "MSG" followed by the message ID and then a stream of strings.
Send "ACK" followed by the message ID after each MSG.

Send "KEEPALIVE" every 15 seconds to keep the connection active.
The server sends "ALIVE" to report that the connection is active.

Send "DISCONNECT" to correctly close the connection.

This is a bit blur,
Do you have an exemple somewhere to allow me doing something like I did here : MXS LiveTiming (http://msx-concept.com/livetiming/)

Speaking of timing, I ran a bunch of laps online on Holjes on the SM bike and I don't see my time up there. I've done several sessions, some alone. I do see my times for Forest and Practice Track Short however.

Could you be a bit more specific? I just started trying around with this, maybe I can help.
What have you tried so far? And what did you have to do to get your site to work with MXS? (By the way your link doesn't work as it is.)

Yep I inverted 2 letters, it's http://mxs-concept.com/livetiming/ (http://mxs-concept.com/livetiming/)

I don't understand the way you can receive, for my livetiming on mxsimulator I think the strategy is totally different, the game server is writting a text file with all info as they come (rider 2 pass the second checkpoint for exemple) and I'm reading into that file.
Next at the end of the race a command send this file where I want to decode it and display championship results ie.

Ah ok, here you have to connect to the server that sends the information (track, players, split times and so on) to you. UDP is used for that.
I don't know about your "qualifications". Are you just looking for some example code or how to do it at all?

Maybe I have to understand if it will needed or not for the races and championships we will do. At the moment I think I'll focus myself on track making as the game is a bit poor at this level.  ;)

Can anybody help me with this? I'm looking to get live timing off of the Weekend Warriors FLCS2 server. Preferably, if it's possible I would love to be able to connect and download all the information from the server over the past week that it's been running but I doubt that's possible, or i could say that it's probably umpossible haha.

well I didn't even enabled live in my server config file tbh., never saw a reasonable point behind that

Edit // enabled it now but I can't even connect to the port i defined there, dunno

First post updated to add a parameter to the "START" command, that allows to receive the track centerline and bikes' track position, too.

First post updated to add the messages data format.

Thanks for the new informations about blocs.
Could you add Empty string after every blocs ? It will be easier to process them.

Thanks ! It will be clearer than testing every line if it's bloc names to know if it's new bloc or not.

Is it possible to add session informations (Number of lap and Duration) in the live timing bloc ?

Example :
SESSIONSETUP
Number of lap
Duration

If what you're saying is a suggestion for B15, don't mind me.
If it is not a suggestion for B15; MXB currently doesn't support races based on minutes and laps (however I do believe that's been implemented for B15 already). You can get the session time though. For races, it'll display the minutes left, and for practice it'll show the total time that has passed since the start of te session.

You can get this information from the classification section, then look for session timer.

The problem with the session timer in classification, it gives the time since the begining of the session, for race too. So it's hard to create countdown on live timing dashboard because it's not possible to get the configuration of the session.

For the race, it's the same. It's possible to get the current lap of the first player, but not the number of lap for the full race. So, it's not possible to display : "Lap 5/15" now.

In my example, I have add two lines 'Number of lap' and 'Duration' but as you said, it's not possible to create session defined by this two parameters in the same time, so the bloc could be more than :

SESSIONSETUP
TYPE
- Duration
- Lap
Number of lap OR Duration

Concrete example :
SESSIONSETUP
LAP
15

You could get the max laps per server from my or the official server page

Simple XML or JSON parse should do the trick

It's very ugly to use other website to get information when you directly can exchange informations with the server. For example : If official server page is down, my live timing will be down ...

First post updated with the latest messages data format:
- added an empty string at the end of each message
- added "type" to EVENT
- added "Extra Data" to ENTRY
- added "Average Speed" to LAP
- added the session length and laps to CLASSIFICATION
- PREQUALIFY has been changed to PRE-QUALIFY

A link to example source code has been added, too.

Can the HOLESHOT be added as a new MSG?

Would also help if the ENTRY record contained a status if the player was disconnected.  For example, if you connect to live timing during a practice session, and a player had already disconnected, you will never receive the ENTRYREMOVE MSG, but they are sent in the ENTRY MSG until the session changes.

The HOLESHOT message will be added to the next MX Bikes update.

Please note that entries and clients are not the same.
The ENTRYREMOVE message is only sent when the client that disconnects has not recorded any lap.

Thanks, but the connected clients are not sent in any of the messages.  So, we can't tell who is connected or not if they did record a lap.  This would be helpful to know so we can tell which clients are connected and valid to send remote admin commands to.

Would you be able to update the CLASSIFICATION when a split is crossed by a player instead of only at the start/finish? 

Currently, you do not have accurate results in live timing and in the game (replay screen or MaxHud plugin) until the player has crossed the start/finish for the second time.  This is especially bad on tracks such as Mantua or Washington where the start/finish is far away from the start gate.  So, you end up not getting updated classifications until almost the end of the 2nd lap because they have only crossed the start/finish 2 times. 

If you included the split times in the timing and update of the classifications, the live timing would be much more useful to streamers and players as the results would update 3 times per lap - at each split and the start/finish.

Also, splits are not posted until the rider starts the first "official" lap as well.  Again, for a track like Manuta, the start gate is right after the start/finish.  It would be nice to know who is in the lead on the first lap from the start gate to start/finish.  If you report the splits, even though this isn't an officially recorded lap, then we could at least get the current results on that first lap.

+1

Depending on how large the data is, it could be updated after each checkpoint too. Just like in MX Sim. It is not normal you have to wait 2 laps to know your position, even if I can understand the simulation side where IRL you can see the pitboard in one and only location. But for the live spectating  it's needed.

Were any new features added to live timing or remote admin for B16?  I saw that it now reports the MSG for HOLESHOT.  Is there anything else?

First post updated:
- added info on how to receive the contact messages
- added the HOLESHOT and CONTACT messages data format

First post updated:
- changed the START command parameters
- added "Length" to SESSION
- added "Holeshot" to TRACKDATA

First post updated:
- changed the DRIVERSTATUS and CLASSIFICATION messages data format
