Topic: Alright, REALLY preliminary, something I've been working on for a couple days.

Are you reading the graphic tiles from the rom dynamically or using static built in images?

Woah, you're making progress on this at mach speed it seems! Keep it up! If I have some free time tonight I'll give it a go.

Are you reading the graphic tiles from the rom dynamically or using static built in images?

That's a good question. Would be AWESOME if it were dynamic, as it would give me an incentive to go more in depth with edits to world map graphics than I have so far.

I'm reading the tileset from the ROM.  Here's the code: https://github.com/Entroper/FF4MapEdit/blob/0.3.1/FF4MapEdit/MainWindow.xaml.cs#L176

I have no idea how I would design a UI for tileset editing, but if you've already modified the tiles, the editor will read them just fine.

Hell Yeah!

As far as the graphics-side goes YYCHR is easy enough for tileset editing, plus has that nifty savestate option for viewing palettes so that part can be done without you having to make a UI for the editor to accommodate it.

Thanks! This was the only real thing holding me back from implementing world map editing in FF4kster. Hopefully I can make sense of the code ^_^

This is kind of
 
But I gotta say, I love it when this forum creates an avenue for mutual inspiration!
This is when this @#$% gets really fun!

Feel free to ask if something doesn't make sense.  :)

I've learned a ton from reading the source code to various ROM tools, so part of the reason for doing this project was to let other people read my code and do the same.  The license file will back you up.  :)

Wow, I got a crapton of refactoring done tonight, and I'm really pleased with how it turned out.  After all that, I was able to add a real-time compressed map size label in just a few minutes.

Mainly what I was confused about is detailed here:
http://slickproductions.org/forum/index.php?topic=1866.msg25002#msg25002

Perhaps you can confirm if I was on the right track?

Yeah, it looks like it.  The data at A0800 (headered) is what I call "subtile palette offsets" since they're offsets into the world map palette for each subtile.  Seems an inefficient way to store this, actually, because there are only 4 possible values, but each one consumes an entire byte.  Oh well.

[chillyfeez]

If I had to guess, I'd say that has to do with indexing efficiency - the X value is already set by the tile selection. So while you could store as many as four palette assignments in one byte, it would take a lot more assembly to extract the relevant information when you needed it.

[Entroper]

Sure, it's more convenient in the ASM.  It's just funny sometimes to see where they chose to make things as compact as possible and where they didn't.  Like the snow-capped mountains thing, versus this.

[Squall]

Code: [Select]

private void CopySubTileToTile(byte[] subTiles, int subTilesOffset, ushort[] tile, int tileOffset, ushort[] palette, int paletteOffset)
{
for (int y = 0; y < 8; y++)
{
for (int x = 0; x < 4; x++)
{
byte twoPixels = subTiles[subTilesOffset + 4 * y + x];

byte pixel = (byte)(twoPixels & 0x0F);
tile[tileOffset + 16 * y + 2 * x] = palette[paletteOffset + pixel];

pixel = (byte)((twoPixels & 0xF0) >> 4);
tile[tileOffset + 16 * y + 2 * x + 1] = palette[paletteOffset + pixel];
}
}
}
Hmmm does not FF4 use bitlanes to internally store tiles? That code looks like for GBA :D

[Entroper]

Yeah, just straight 4bpp linear pixels.

[Entroper]

So, I have the following details about tile properties from FF4Ed:

Code: [Select]

#define LDF_WALK                0x0001
#define LDF_UNKNOWN1            0x0006
#define LDF_SAVEPOINT            0x0008
#define LDF_UNKNOWN2            0x00F0

#define LDF_WALKDAMAGE            0x0100
#define LDF_UNKNOWN3            0x0200
#define LDF_HIDECHARACTER        0x0400
#define LDF_TOPHALFCHARACTER    0x0800
#define LDF_EXIT                0x1000
#define LDF_UNKNOWN4            0x6000
#define LDF_ENTRANCE            0x8000


Code: [Select]

#define WDF_CHARAWALK            0x0001
#define WDF_CHOCOWALK            0x0002
#define WDF_BLACKCHOCOFLY        0x0004
#define WDF_BLACKCHOCOLAND        0x0008
#define WDF_HOVERCRAFTMOVE        0x0010
#define WDF_AIRSHIPFLY            0x0020
#define WDF_CHARAWALK2            0x0040
#define WDF_BIGWHALEFLY            0x0080

#define WDF_BATTLEBACKGROUND    0x0700
#define WDF_SHOWCHARATOPHALF    0x0800
#define WDF_AIRSHIPLAND            0x1000
#define WDF_UNKNOWN2            0x2000
#define WDF_ENEMYENCOUNTERS        0x4000
#define WDF_ENTRANCE            0x8000

That's for area maps and world maps, respectively.

Do we know if the flags labeled UNKNOWN are used at all?

  Wait, and what the hell is CHARAWALK2?!
