    Notes



    1. A string must always have 0x00 as its last byte. So a 64 byte string only has place for 63 characters, followed by 0x00. Even more,the string automatically ends at 0x00, even if it appears somewhere in the middle of the originally intended string.

    2. Most sections translate pretty straight-forwardly to a tab in Civ3Edit. The name in brackets is the name of the editor tab.
    The sections in this file appear alphabetically ordered by their 4 character identifier.
    A superfluous section, i.e. one that uses the Civ3 defaults, can be left out entirely. So for a simple map, all sections up to the WCHR section can be left out.

    3. I've tried to keep the value descriptions as close as possible to those used in Civ3Edit. For explanations of the values I refer to the excellent Civ3Edit help system.

    4. References to other items (e.g. items in a drop-down box or radio button list in Civ3Edit) are often done by the zero-based index number of the position of that item in its section. -1 Usually means it doesn't refer to anything (e.g. the "None" option in a Civ3Edit drop-down box). Further on, only details for data differing from this standard will be explained.

    5. For data mentioned in binary, only the used bits are mentioned. When multiple bytes are being described, the data is shown grouped per byte. In that case, only the used bytes are shown, the remaining bytes are filled with zeros. In any case, for things that appear in checkboxes in Civ3Edit, 1 means it's checked, 0 means it isn't.

    6. The "turns to complete" is modified by the movement cost of the terrain. The value given in this section applies to terrain with a movement cost of 2 (e.g. Forest). Terrain with a movement cost of 1 is worked in half the time, terrain with a movement cost of 3 needs 50% more turns to work.

    7. A byte, split into the first 4 and the second 4 bits.
    The first 4 bytes are the "real" terraintype (0 is Desert, 1 is Plains etc. BUT: Bonus Grassland, Snow-Capped Mountains and Pine Forest are NOT separate terrains, they're merely a variation on Grassland, Mountains and Forest, respectively).
    The second 4 bytes are the "base filler" terrain. This is especially used for Forest, which can be placed on top of different "base filler" terrains.

          Actually there is more to the BICs then the maps, and each section follows a specific pattern (except the CULT section, which seam to be different )

          Each section of the file starts with a 4 byte string identifying the section. After that (except CULT) a long containing the number of that type, and after that the type begins. They start with a long telling the lenght of the following spirit.

          And the thing in you note 1 is actualt a length of the data header.

          I'll see if I can post the RACE format soon.
          (I have it in Swedish )

          Also ALL references to a specific thing (resource terrain, what so ever is made to the ID – 0xFFFFFFFF = None)

          The ID is the number in row after the initial name. Start count from 0.

            -- RACE format removed from this post --
            The Format can be found in the first post

              hehe, I know
              Iīve added everything Iīve been doing today. Sorry for the plenty of dots nearer the end, but it did get kinda tedious. The format is remarkably simple, and most sections map directly to a tab in the civ3 rules editor.

              I havenīt added your stuff yet (well, not the parts I didnīt find as well)

                Well, I know a lot of those formats without having the editor, and I know most of what you posted before, but my copy tool only uses the civ stuff (It had to read the names, and to get to them it had to read cities, leatders and ao on, so I made it read everything.) and the main format. +the Cult format (to be able to skip over it.)

                    Your things have been added. I vaguely checked most of it, you mixed up one or two things, and I changed some names to the names used in the rules editor... Great job!
                    It looks like weīre on our own though. But then again, this format isnīt nearly as vague as the civ2 formats were.
                    Oh, and you sound like you already know the BIC file format. Is it some kind of standard?

                      I see it now. I don't use them in my program, so I didn't care more then that they existed. (How can you mix up one thing?) Was it only the Noun<->Adjective for civs, or was it anything else.

                      I'm also happy that you confirmed all those I was not sure about. (I only had a picture of Romans and one of Barbarians)

                      Regarding the format:
                      No I've not seen it before, but most of it is some sort of default for binary formats. (Even thou the 4 byte strings in the start of each section is something new.) If I would make a binary format I would always specify the length of everything that could possibly change length (also if only in later versions). I would also try to keep things in the same way all over the file, and I would do it the easiest way, and it seem to be exactly how Firaxis has done it.

                        BTW - the resource on a map is the index just as any other reference. (Resources can be added you know.)

                          The thing could be a pair of things.

                          I think that was it.

                          I'm also happy that you confirmed all those I was not sure about. (I only had a picture of Romans and one of Barbarians)


                          Yes, I am not entirely sure about the barbarian RACE_... though. Maybe Iīm just mistaken, but somehow it looks a bit different from the others. I havenīt looked into it too much though. The only serious difference I can tell right now is that the barbarian "city names" are rather tribe names.

                          Regarding the format:

                          Oh I see...
                          Is the format I use good enough, by the way? And a difference between our "styles", I use the "remaining length" as a name for those numbers, because I feel like those numbers themselves are also part of the data... But well, as long as itīs clear.

                          And yes, Firaxis has at least done a great job over here.

                            As far as I can see it is the same. It has culture -1 and no leaders ruler, rulertitle and animations specified. The structures are still there, just filled with 0x00.


                            Oh I see...

                            Yes it is clear. I prefer to see the length numbers as a part of the mainformat, telling the length of the following structure, (as it is how I usually program myself when making binary formats.) First I decide what I want to save. Then I build up sub formats for those, and as some of them contain variable length things I add a length of it in the beginning of the structure. Sometimes when I work with smaller structures I sue short or even bytes for the structure length, but have a continue code that can be used to continue on the earlier structure after read that code. Those codes do I usually see as a part of the main file format, and not as a part of the sub formats. And also that they don't contain any useful data if you don't want to skip over those structures.
                            And yes, Firaxis has at least done a great job over here.
                            Yes, they have made a very simple format. I wonder if they wanted us to hack it or if they just were to lazy to make it complicated

                              Rivers

                              I've been looking into the short from the map section that is labeled as river information. The first byte of the short (or the second byte in the hex editor, isn't Little Endian irritating?) doesn't seem to have any influence. If it is set to anything other than 0x00 it brings up an image from the Territory.pcx terrain file. The other byte on the other hand seems to be a bitwise flag, that I am messing around with now that I am done with school for the week.

                              How are you supposed to get the width and height of the encoded map if all the file give is width/2*height?
