You can see very clearly that unknown2 (bottom 22 bits) are some kind of bitfield, and unknown1 (top 12 bits) have very high steps suggesting it took too many bits.

Maybe unknown is 8:4:4:4:4:4:4 or something. Most of bottom bits are almost certainly some bitfield, not index or id. With top bits nobody knows.

8 bit ID, 24 bit bitfield looks entirely plausible - but even then unknown1 might have fewer bits than 8, its lowest one or two bits look suspicious.

If you see anything, tell me.

split unknown in more than 2 parts?

Here's bit co-occurrence matrix for unknown field.

I'm not entirely sure that count(a&b)^2 / count(a) / count(b) is the correct thing to measure... ;-)

I'll think of a better metric to plot later.

Bit:       31  30  29  28  27  26  25  24  23  22  21  20  19  18  17  16  15  14  13  12  11  10  09  08  07  06  05  04  03  02  01  00

Negative values cor0/1, cor4/5, cor8/9, cor12/13, cor16/17, cor20/21, and lack of negative values in cor24..31 block suggest correct breakdown is:

8 bits ID,
4 bits
4 bits
4 bits
4 bits
4 bits
4 bits

Or in hex notation 2:1:1:1:1:1:1 hex digits.

cor12/14 and cor12/15 are not entirely consistent with this, but considering how messy the data is in general it's close enough.


... and S2TW pathfinding has 4th bit always 0, sort of violating my results, and bottom 24 bits not behaving terribly much like bitfield. Even there there's still pretty strong 8:24 division.

So I'll divide unknown into 8:24 for now and leave it to you guys to figure it out.
unknown1 should probably be read as decimal.
unknown2 as hex, with each hexdigit meaning something separate.

taw, don't forget post #374

taw, don't forget post #374

What post #374?

And how those meaningful path_ids are to be generated again?

Me pull list of regions from some magical place since it's not in pathfinding.esf

Then i2_ary contains indexes to it.

Then u2_ary contains indexes to i2_ary. 0 is which path then? "0 <!-- separator -->" ???

And none of that works at all for NTW DLC pathfinding.esfs right?

Can't you put generated comments in an array?

stupid question

signed hex should have 0 or 1 at first digit?

[taw]

stupid question

Wait, what?

-1 in 32bit hex is 0xFFFFFFFF.

+1 in 32bit hex is 0x00000001.

[PietroMicca]

Wait, what?

-1 in 32bit hex is 0xFFFFFFFF.

+1 in 32bit hex is 0x00000001.

ok I have a theory buzzing in my head

unknown 8 digits 2:3:3

the first 2 a sort of unknown id
the second 3 signed values multiple of 16 and so the last 3

it would be possible?

[taw]

Added [uint2, int3, uint3] in comment, enjoy.

[PietroMicca]

Added [uint2, int3, uint3] in comment, enjoy.

why you have done it for unknown1?

I just want unknown2 split in 2 part, the first one signed

[taw]

Then I have no idea what you're talking about. There are 24 bits in unknown2.

You want it split into [int12, uint12] ? I've done it in the code, but it's obviously wrong.

The only negative numbers you'll ever see are in S2TW, I don't think there are any in ETW pathfinding.esf ever.

[PietroMicca]

We have to give up for now.

Maybe we'll be more successful in startpos campaign_pathfinder.

[taw]

path_ids now have comments. No idea if they are correct. What I see doesn't look terribly sensible.

[PietroMicca]

you have built your array in the wrong way

you have put sea as first element of this array

listed regions, sea and at last what you see after the separator

you have an <u2_ary>, put comments in order of apparition as elements of an array and replace separator comment with sea

[taw]

I don't understand you. Just explain it as an example.
