I wanted to see if I could decode a replay file. As it turns out, I could.
Now, I'm not sure what I want to do with it, so I might as well set it free...

There are a couple of bytes that I have yet to decipher, but it parses 99% of the information.

	coh.replayparser.rar
	Size: 6.73k
	Number of downloads: 401

Could you (technically) manipulate it so you change the outcome of the match? Given enough understanding of the files lol.

(Very) theroetically, yes

what's this?

+1



Is it something similar to CoHRA?

It's a piece of code that will extract commands, messages etc from a replay file.
It is not an application in it self.

And for what could you use it?

to parse replays...

so u posted .cs class files and now what i need to write exe app and use it ?

Great stuff!!!

To everybody who doesn't know what it does: this is a new engine like the one in CoH Replay Analyzer (COHRA) for which we had no source code.

I tried it and ... have some questions.

What's the supposed format of the actionDefinitions file?
I tried cohra.dat which is in the format Dyxtra used for COHRA and the replay parser didn't like it. Example:
COHRA: 9,0,BUILDING,"Barracks",0x5eb,1
replay parser: 9,0,"Barracks",1

The action type (BUILDING) doesn't seem to be stored anywhere else and 0x5eb is the actual action ID - how can replay parser work without those?

I used aramonkg's cohra.dat file for 2.602

How does one get / set the mod name?
Not directly related to replay parser ofc: replayParser.replay.modName is RelicCoH for a BK mod game.

replayParser.replay.mapDescription wrong?
replayParser.replay.mapDescription: "0990\0$60995\0Ā\0Ā\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0Ȁ\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0Ā但䑌义但

This is the map description for Langres.

In any case very impressive work--especially compared to the mess I coded for CohReplayLister. BTW: I can update it to recognize 2.602 replays if anyone is interested.

Oh, thanks a lot for sharing the source code!

The format is: action type, action id, description, has-location-flag, ie. coordinates on the map.
I haven't gotten around to make a table that maps action type to a description.


Good question - I only tested with vanilla games and assumed it was the actual name of the mod.


Hm, interesting. It's 4 bytes off. I haven't seen that before.
It should be $60995


Thx and np

Btw, feel free to do whatever you want with it.

Edit: My original plan was to combine your idea with cohra with an underlying database (sqlite initially) and add a query interface so you could create statistics.

How about using Dyxtra's format even if you don't need all it's fields? That would give us a complete list of action IDs right now.

Of course I could just make the required changes for my own use. But I very much prefer a solution that is readily available to everybody.


I'll try with other maps.


"Was" like "not gonna happen" or like "when I have time"? Getting statistics for tourney after-action-reports and the like would be absolutely awesome.

Let me know if you'd like some help for example a GUI.

I don't have the time or energy atm. to finish it and rather than leaving it to fester in my svn, I posted it here in the hope that someone would find use of it.

You're more than welcome to modify the code and if you do I hoe you post the updated code, so I and others can benefit from it.

Yes please!
Or just give some pointers to what changes there might be

Problem is I failed to find out what distinguishes 2.602 replays from 2.601 ones. Main Version and chunk format specifier are the same.

Ah, so I am right in assuming that this code is fully compatible with 2.602 replays as well? Great!

Well, ReplayLister doesn't explode if you tell it to list 2.602 replays--it will show them as being 2.601 replays. But one of it's duties is to show you whether a replay will work with your CoH install. And 2.601 replays don't work with a 2.602 install.

There is a bug with filtering for the russian faction though. But as nobody complained yet I take it no one uses it anyway .

In case you are referring to pingtoft's code: I guess it's compatible with 2.602 replays but haven't checked.

I tested my code solely on 2.602 replays.
