Structure of edifice.bst

File Structure Overview

Offset 0x0000 to 0x0003 number of buildings
Offset 0x0004 to 0x0007 address of the buildings address map (file offset)
Offset 0x0008 to 0x01F3 tech map (496 bytes)
Offset 0x01F4 to 0x02E3 ignore list (240 bytes)
Offset 0x02E4 to 0x???? building data (n * 176 bytes)

Followed by address map (n * 4 bytes).

Structure of various sub-blocks

Tech map

Offset 0x0008 to 0x0009 number of buildings with biotech requirement
Offset 0x000A to 0x000B number of buildings with computer requirement
Offset 0x000C to 0x000D number of buildings with construction requirement
Offset 0x000E to 0x000F number of buildings with energy requirement
Offset 0x0010 to 0x0011 number of buildings with propulsion requirement
Offset 0x0012 to 0x0013 number of buildings with weapons requirement
Offset 0x0014 to 0x0015 number of buildings with All techs requirement

Offset 0x0016 to 0x0017 0x0000 (separator?)

Followed by: (offset 0x0018 to 0x01F3 - 476 bytes)

Code: Select all

For each tech requirement (7)
    For each tech level (10)
        address (4 bytes) of the first building with given tech req. and level

    0x00000000 separator? (4 bytes)

    For each tech level (10)
        number of buildings with given tech req. and level (2 bytes)

    0x00000000 separator? (4 bytes)

Ignore list

Code: Select all

For each empire (5)
    bit mask of all the buildings (48 bytes == 384 bits)

The bit index of a building in the list is calculated as 2^(building index) - 1

If the bit is set to 1, this means the building is ignored. The way UE sets these is it checks if the building can be build by the empire and then sets the bit to 0 (if it can) or 1 (if it can't).

Building data

Each building takes up 176 bytes. The listed building need to be sorted by tech requirement and tech level.

Each building consists of:

Offset 0x0000 to 0x0027 Singular name (40 bytes)
Offset 0x0028 to 0x004F Plural name (40 bytes)

All strings need to end with a 0x00 byte.

Address map

Consists of 4 byte addresses (file offsets) pointing to the start of a building's data entry. Addresses are sorted by building id.

To get the file offset of building with ID 0, you would look at the first address, for building with ID 30, you'd look at the 31st address.

I've just read that topic... looks like buildings with technology requirements above ten would require a major code re-write :.(

thanks thought for that infomation anyway it helped me to correct some of my misconceptions about the edifce.bst file

given what i said,

Offset 0x0016 to 0x0017 0x0000 (separator?)

could tihs have been left for sociology?

Code:

Code: Select all

For each empire (5) 
    bit mask of all the buildings (48 bytes == 384 bits)

therefore this implies the maximum number of buildings is 384

is UE set up to use extra buildings at the moment? or just standard 318?

so as i under stand this

Code: Select all

Offset 0x0000 to 0x0003 number of buildings (adding an extra 66)
	3e 01 00 00	->	80 01 00 00
		318	->	384

=================================================

Offset 0x0004 to 0x0007 address of the buildings address map (file offset)
	84 DD 00 00	->	E4 0A 01 00

sets the file for the maximum 384 buildings,

add 66 buildings data to the end(?) or the 318*176 byte block (not sure what these'll be

)

addjust Offset 0x0008 to 0x01F3 tech map (496 bytes) and Offset 0x01F4 to 0x02E3 ignore list (240 bytes) as appropriate

#
are there any changes required in trek.exe -- do you know if it is setup to use 318 building i.e. hard coded or is this read from the first four bytes of this file?

Offset 0x0016 to 0x0017 0x0000 (separator?)

could tihs have been left for sociology?[/quote]

Possibly, yes. But it would then probably read as bio, ..., soc, All instead of bio, ..., All, soc

is UE set up to use extra buildings at the moment? or just standard 318?

It should be able to read/save a file with more buildings, but this is untested.

are there any changes required in trek.exe -- do you know if it is setup to use 318 building i.e. hard coded or is this read from the first four bytes of this file?

It probably works the same as for shiplist.sst. The number of buildings is likely to be found multiple times in trek.exe, you'd need to find them all.

Post by **Peter1981** » Fri Jul 09, 2010 2:19 pm

since i last posted i've added 66 test buildings to the edifice.bst and am continuing my efforts. Thanks for the quick reply DCER

, I will post back once i've done some test. It's good to here that UE might read this file (again i'll post how that goes asap

)

Post by **Tethys** » Fri Jul 09, 2010 6:09 pm

Also let me know how it goes Peter, I am looking to add buildings to the game as well

Post by **Peter1981** » Fri Jul 09, 2010 6:11 pm

Without making any changes (except those required by UE trek.exe update) the initial test (Fedz) generated this

as expected this mean there is gold in the trek.exe to be uncovered hovever i detected only 42 instances of 318 in trek.exe so will work on these and 317.

well that solves the crash at the start of the game and in f4 (science screen) i can see all the buildings. -- testing further...

However on selecting a building in F4 screen with an id > 318 CTD mo crash log

this seems to be a loop increment ?

no noticeable effect?

yet another CTD

but...

i solved this bu reducing the number of buildings to less than 0F which is the test for this error

for the popup screen

However UE or I've broken colonisation F1 F7 M1 P7 I7 should be F1 M1 P1 I1 U1 .... EDIT: sorted out the upgrade colony issue

This is wonderful news! I cant wait to get some new buildings in my mod! Good work Peter and DCER! You guys are great!

Post by **Peter1981** » Mon Jul 12, 2010 6:37 pm

It should be able to read/save a file with more buildings, but this is untested

UE seems to work well with new i.e. extra buildings

Post by **Gowron** » Sun Jul 18, 2010 7:13 am

Thank you very much for this overview, DCER

Just one tiny thing:

DCER wrote: Offset 0x0000 to 0x0003 number of buildings

Isn't it the highest index (= number of buildings minus one)?

Post by **DCER** » Sun Jul 18, 2010 2:20 pm

I'm pretty sure it's the number of buildings, maybe used for determining the size of the address map. UE saves it as such and the files I've checked have it set as 318.

If you find it to be otherwise let me know and I'll update my post.
