Demo Replay Error?

(INF3RN0) #1

Anyone have an idea why some of my demos in promod get an error and crash immediately back to the main screen after the map loads? I reset my config, connected to the server it recorded on, and all the tricks I could remember relating to this. Here is my error: ERROR: idGameLocal::ReadClientNetworkInfo Missing Entity For Snapshot State.

I got the same problem sometimes, and I noticed in the demo file, just after the demo that doesn’t work there is another file, not .ndm, I don’t know if there’s a relation… ok I’m useless :smiley:

From what it says, it sounds like an in game entity was missing from the demo (maybe corrupted or something) rendering the demo being unable to open. No idea how you could get around it though :confused:

We need a demo pro fast! :frowning:

demo broken. there is no hope. u die.

(i hope it wasn’t a custom map coz then there is hope)

(rUBBEN) #6

Ah there is a hope to solve a custom map fail demo ?

When you’re about to play the demo it stops :mad: but in the console you will see the following error:


********************
ERROR: idGameLocal::ReadClientNetworkInfo Missing Entity for Snapshot State
********************

:eek: why?

As I said, if it was a custom map, there is hope. But one has to make clear:

what game mode it was
what server it was
what campaign it was (if campaign at all) and provide that campaign file

Edit: as i see from the file it wasn’t a custom map and it was also a stopwatch game

This makes it harder to replay imho.

The best guess would be to connect to the same server in objective mode, best even to launch same map. Then while being connected, launch the demo.

I dont know if you need more but that error you posted means the demo is broken, no chance to bring it back, unless from another PoW

There is another common error with demos that i noticied happens when you’re recording the demo and you force a “/disconnect or /quit” from the current server, you have a demo named .ndm and then a small file named .udm or something like that. These demos have unreal moviments and crosshair doesnt move, demo is “****ed up” even if i think SD could do a tool for avoid this problem because it seems demo (.ndm file) just didnt blend with your moviments (.udm file)

I mostly find this happens when crash or lose i-net connection. Sucks as sometimes you get nice stuff but the demo’s screwed :confused:

These demos (where you have a .ndm and .ucmd file) can be fixed by appending 4 0 bytes onto the .ndm file, changing the 4 bytes at offset 12 in the .ndm file to the file’s original length + 4 (for the new bytes) encoded as a little-endian integer then appending the contents of the .ucmd file onto the .ndm file. Of course there might be other issues with the demo if the game crashed but this worked on the demo I tested it on.

Edit: The attached zip file contains a program to repair the demos as described above. Run it from a command prompt as “demofix demo_in.ndm demo_in.ucmd demo_out.ndm” (without quotes). Source code included, I hope it’s useful :slight_smile:

Ofcourse, I was just going to suggest that :smiley:

Really nice to hear that there is a chance to repair them. But sorry I didn’t understand a word :frowning:

Ignore the technical jargon and do this!

Very useful thing to have, i’ll try it out when i find a naff demo

really thanks, i had like 1\3 of all my demos bugged because i always did “/quit” without stop recording after every match.

If this gonna work i’m going to save at least 30-35 demos that i need

Edit: it works i love you <3

Well, now i know he is not sleeping when in two hours he send no words on #biatch.etqw.

So i will stop to bug him that much!

I compromisse my self to ready the tech explanation again after i regenerate my self from the first read.

yeah grand, timestartey, kudissimos! :slight_smile:

I can’t get it to work :frowning: I get the message:

‘demofix’ is not recognized as an internal or external command, operable program or batch file.

I thought it might be because i have my OS on a seperate HDD to everything else, so when i opened Command Prompt it always started on the OS HDD. I copied the program and demo’s over and it still doesn’t work to this drive and it still doesn’t work! Help! :frowning:

Do you have demofix.exe in command prompt’s current directory?
