Repeated Battle Die Rolls

[DCWhitworth]

We just had the first PBEM battle go into a second day since 1.07 was released and both days had identical die rolls.

Surely a bug with the pre-rolling ?

David:

That certainly would be! Can you post with your save and I will take a look?

[DCWhitworth]

What would you want for this ? Will the save and pbm files do ? Not sure if I can get hold of a battle file but I will try.

Im not as sure as David is
I did test over 4 die rolls and this is the result

Guys I just did a Game test over four battles in the same area, I just kept reloading the game back up for a hot seat game and the dire rolls came like this

Battle 1 France 5,5,6 Austria 6,5,5
Battle 2 France 2,6,6,Austria 4,3,4
Battle 3 France 2,4,7 Austria 3,1,1
Battle 4 France 3,2,4 Austria 5,4,3
Batte 5 France 7,7 Austria 3,6
Battle 6 France 6,3,6 Austria 2,1,2
I have screenpics to back up this test if you want to see them, although there seems a little repeat, but hardly conclusive to say there is a bug.
And yes Napoleon is present on the french side
Also I have loaded a hotseat game where you can just load the file then move the French Troops into Mantua where the autrians are awaiting, I have repeated this move 6 or more times
Ive put an autosave Land file in here for you to have a test for yourself
Thanks
Gaz

Are we talking about the same thing here ? This was the two day battle in Warsaw where identical die rolls occurred on day one and day two.

Well you are talking about one battle, Im talking about 6 or more and testing whether or not there is a repeat in the program isnt that the same thing? To check if the program is faulty
To have a fair test this should be repeated, correct me if Im wrong

Well the odds of getting a sequence of six die rolls exactly repeated the next day is somewhere over 40,000 to 1, unfortunately the post detailing this event isn't in the TGHQ forum any more.

I realise the odds of a repeatative die roll but I thought that 6 battle die rolls might be objective thats all

It's the last three lines of the last post that I'm talking about, not Allrocco's comment about the Austro/Russian battle in the first post.

The implcation to me is that the pre-generated rolls in PBEM battle files were not refreshed for the second day of fighting and were re-used.

This isn't a question about whether the game die-rolling is properly random.

Ok that makes it a little clearer now thanks[:)]

I'm pretty sure DC is talking about SECOND DAY rolls, not battle to battle.
 
I'm fairly confused why this is such an issue. Random die rolling can be as simple as:
 
srand(time(NULL));
die = rand % 6+1;
 
This isn't the first time this has been a problem.

I recall that there was some discussion about adding pre-generated die rolls for a battle as a security measure to prevent players from reloading to get the rolls they want. Has that now been implemented? If so, it sounds as if this could be an unintended consequence: game generates a sequence of rolls for a given battle, which cannot be changed; but fails to distinguish for that purpose between day 1 and day 2 of the same battle?

That's exactly what I intended to say. [:)]

This could be a problem with the pre-roll code which just started in 1.07!

[Dancing Bear]

Was this a confirmed bug?

[datacollectioncenter]

Correct.

Hi Marshall,
Any idea when this particular bug will be patched?  I assume its coming out with .08, this that correct?
