Map Information
Data structures
struct FFTA_map
0x58 bytes
Member name | Length | Offset | Type | Maximum value | Description |
---|---|---|---|---|---|
Graphics Data | 4 | 0x00 | Pointer | N/A | A pointer diff pointing to the beginning of the map tile graphics data. |
Arrangement Data | 4 | 0x04 | Pointer | N/A | A pointer diff pointing to the beginning of the data that arranges the tiles. |
Unknown | 4 | 0x08 | Pointer | N/A | A pointer diff pointing to something that has to do with clipping. |
Palette Data | 4 | 0x0C | Pointer | N/A | A pointer diff pointing to the beginning of the palette data. |
Height-Map Data | 4 | 0x10 | Pointer | N/A | A pointer diff pointing to the beginning of the height-map data. |
Animation Data | 4 | 0x14 | Pointer | N/A | A pointer diff pointing to the beginning of the animation data. |
Animation Graphics Data | 4 | 0x18 | Pointer | N/A | A pointer diff pointing to the beginning of the raw animation tile data. |
Animation Destination | 4 | 0x1C | Pointer | N/A | A pointer to where the Animation Data should be stored in the RAM.
|
Further Animation Data | 0x10 | 0x20 | 4 Pointers | N/A | An array of 4 pointer diffs pointing to the beginning of extra animation data. |
Further Animation Graphics Data | 0x10 | 0x30 | 4 Pointers | N/A | An array of 4 pointer diffs pointing to the beginning of extra animation tile data. |
Further Animation Destinations | 0x10 | 0x40 | 4 Pointers | N/A | An array of 4 pointers to where the Animation Data should be stored in the RAM.
|
Unknown | 4 | 0x50 | 32-bit Int | N/A | Unknown. Never appears to be used. |
Unknown | 1 | 0x54 | Byte | N/A | Unknown. 0b??????PP
|
Unknown | 1 | 0x55 | Byte | N/A | Unknown. Appears to mostly be a copy of the previous byte + 0x10. |
Palette Index | 1 | 0x56 | Byte | N/A | This is the index to be used if the Palette Data bits indicate it is required. (From byte 0x54) |
Buffer | 1 | 0x57 | Byte | 0x00 | Never used. |
All pointer diffs in this structure are against 0x08569104.
struct FFTA_map_tile
struct FFTA_map_tile { uint8 Height; int8 Permissions; };
- Height: The height of the tile. There is no offset from what is displayed. Setting to higher than 99 (0x63) causes graphical glitches, but no crashing. Setting to 0 makes the tile invalid, such that it can't be selected. This value is unsigned.
- Permissions:
- Values:
- 0x00 - Normal. Can be walked on.
- 0x01 - Impassable. Can not be walked on.
- 0x02 - Water. Can be walked on.
- Else - Non-selectable. Can not be walked on or selected.
Data layout
In RAM
Each block of map data starts at the top corner, and goes toward the right corner. The end of a row seems to be padded such that the last couple of bytes, until 0xXF, are zero. Unknown what happens if modified.
0x02007CB0(block of FFTA_map_tile): Beginning of map data in RAM
...
0x02007F14(void*): Pointer to 0x02007CB0. If changed, map data changes to correspond to the new pointer.
...
0x02007F1D(u?int8): NW-SE dimension of the map.
0x02007F1E(u?int8): Unknown. Set to 0x0C.
0x02007F1F(u?int8): NE-SW dimension of the map.
In ROM
0x08019E7C(4 bytes): 0x02007CB0 - Address to start reading map height data from in scenes
0x0801F0DC(4 bytes): 0x02007CB0 - Address to write map height data to
0x08569104 - 0x0856915B: Map data pointers for map 0
0x08569104(Pointer): Pointer to map tile graphics data in map 0
0x08569108(Pointer): Pointer to map tile arrangement data in map 0
0x0856910C(Pointer): Pointer to unknown data in map 0
0x08569110(Pointer): Pointer to palette data in map 0
0x08569114(Pointer): Pointer to map height data in map 0
Default locations of map data
Tile graphics data | Tile arrangement data | Unknown data | Palette data | Map height data | |
---|---|---|---|---|---|
Map 0 | 0x0856C8B4 | 0x0856F528 | 0x0856FEF8 | 0x0856F4A8 | 0x085704C8 |
- There are 163 maps, indexed from 0x00 to 0xA2. Most maps have a night version (palette shift), too.
