Maniaplanet Forum

Hi all

I'm working on a new features for my application and I'm looking at retrieving car location from a replay. I think I've already found the section where the data are, but I can't get how there are arrange (data / offset position / length).

The section is 0303F006 but it is not in the reference table of the GBX on the wiki. I think it works almost the same way as the 0303F005 but I can't found out how to get usable data.

If someone from Nadeo or a member may give me a hint, that would be nice !

The layout of chunk 0303F006 is:
The described part of the layout of chunk 0303F005 in the Wiki seems to be correct.

Damm, I may not be on the right page. Thanks for the reply !

I'm taking all information from here : http://en.tm-wiki.org/wiki/GBX

Is there another wiki for maniaplanet 2 ? Where did you find your source ?

I'm taking all information from here : http://en.tm-wiki.org/wiki/GBX

This documentation describes the Gbx file format of TMNF. Only the headers and some chunks (blocks, lightmaps) of the compressed body are updated for Maniaplanet.

Where did you find your source ?

Directly from the executable. It looks like the description of chunk 0303F005 is not complete. Depending of "IsReplaying" more data fields follows.

Thanks for your reply. That explain why I wasn't able to get what I want.

You wrote"from the executable". What do you mean exactly ? Are your using ManiaplanetLauncher with an argument to get this information ? How I may get those infos ? Sorry for asking some question that might seems to be stupid

I think that it's harder than only adding an argument to the game.

Yes, I think it must not be the correct way, but we can dream

Electron, may you help me ?

Some things should remain internal/closed. I don't know if this subject is one of them. I have no interest to write a tool to read this data section and to interpret them.
If you're so advanced and need information that goes beyond the Wiki documentation, then I will research and try to answer your specific questions.

Ok thanks.

In fact, I was expected this kind of answer, since Nadeo should protect its informations. What I just need is to locate and extract CGameGhostInfo, especially Player location, speed, angle etc. I don't want to trick the replay, I just want to extract trajectory.
Since this part is documented in WIKI, I think it wouldn't be an issues. However, I can't put an hand on the 03 03F 005 (CGameGhostInfo) on a Replay.Gbx file and I'm sure it contain position. May the chunk have a different ID ?

EDIT : Maybe I should contact Nadeo team directly to see if it's possible to retrieve those data ...
