Star Wars Galactic battlegrounds support #421

MayeulC · 2015-12-20T00:51:16Z

Hi there,

I was wondering if this engine re-implementation could support Star Wars:Galactic battlegrounds assets; it's one of my favorite games (I like it a lot more than the vanilla ages of empire II).

It is using (as far as I know) the same engine, with some custom modifications, like Flying units, shields, energy and such.

AOE I support Integrate Age of Empires I #808
ROR support Integrate Rise of Rome (AoK prequel) #785

If we're awesome enough this only requires that the converter supports the swgb assets. The engine should, by this time, be generic enough that the data pack created by convert is loaded and it'll work out of the box™.

I looked into this a while ago. there are two "big" differences between the Age2 and SWGB formats:

DRS copyright header is 60 chars for SWGB instead of 40
SWGB has genie.dat instead of empires2.dat, and genie_x1.dat for Clone Campaigns. the formats for these files are a bit different from the empires2_x1_p1.dat format.

other than that it should mostly ~work.

First of all, I'm sorry if my English is not very good... I'm working on trying to add support to the SWGB. I've modified a couple of scripts and "looks" like it reads the DRS files. The problem comes when openage try to finding the palette.

Where can i find the interface directory? And the "struct" in folders? or something for the drs/dat files?

Thanks :)

TheJJ · 2017-10-02T20:27:35Z

This interface directory is mounted from the interfac.drs file (in openage/convert/main.py). It may be that the "normal" palette file has a different id for SWGB, for aoe2 it's 50500, but it may be different here.

What "struct" folders do you mean?

goto-bus-stop · 2017-10-02T20:32:40Z

SWGB's default palette is also 50500. It should be looking for 50500.bina though, not 50500.bin. Are you working off of the latest master branch @elraro?

elraro · 2017-10-02T20:36:52Z

@goto-bus-stop yes, master branch. i "unzip" the interfac.drs file with this: http://aluigi.altervista.org/quickbms.htm to check if 50500.bina exist. But i found 50500.bin, thats why i rename in driver.py

goto-bus-stop · 2017-10-02T20:38:50Z

Gotcha, but openage extracts them as .bina :)

elraro · 2017-10-02T20:48:12Z

I have opened the file 50500.bin and yes, its a palette, the header with a hexadecimal editor is: JASC-PAL

@goto-bus-stop okey. But same error. I think somethink is wrong with my mount_drs_archives() I will try to debug :)

elraro · 2017-10-02T21:05:29Z

Found the problem :)

FILE_VERSION is hardcoded!

Uhm, what could it be? This crash with data b'\xff'I checked struct with https://github.com/Tapsa/genieutils (changed walk_sprite_rate to int_32, but i dont know if its correct...

void TerrainPassGraphic::serializeObject()
{
  serialize<int32_t>(ExitTileSpriteID);
  serialize<int32_t>(EnterTileSpriteID);
  serialize<int32_t>(WalkTileSpriteID);
  if (getGameVersion() < GV_SWGB)
  {
    int32_t replicationAmount = WalkSpriteRate;
    serialize<int32_t>(replicationAmount);
    WalkSpriteRate = replicationAmount;
  }
  else
  {
    serialize<float>(WalkSpriteRate);
  }
}

How many changes to the dat file reading did you make? I fear there's many differences that have to be adapted first.

The gamedata-reading framework is not that fit for multiple dat-versions yet, we have to add this as well.

elraro · 2017-10-03T09:38:20Z

@TheJJ only changed walk_sprite_rate in TerrainPassGraphic to `int_32, but im not sure about this....

Yeah, i know. I will try and compare the reader with this lib: https://github.com/elraro/genieutils

heinezen · 2017-10-03T17:37:23Z

There isn't even an empires.dat in SWGB. GENIE.DAT and genie_x1.dat look like their counterparts. Did you try to read these files?

elraro · 2017-10-03T17:47:09Z

@heinezen yes of course

TheJJ · 2017-10-03T17:50:08Z

To explore the files and extract content, https://github.com/SFTtech/openage/blob/master/doc/convert/interactive.md might be helpful for you.

For the .dat files, genieutils and the AGE are probably the best source.

Ok, thanks!
