"CFE60, first six bytes are offsets to overworld/underworld/moon, CFE66-CFFFF are the triggers"
chillyfeez said:
"World map triggers are preceded by six bytes indicating the offsets that begin overworld, underworld and moon, in that order."
"So you can move some triggers between worlds if you need to."
"Also, you can use yousei's editor to view exact trigger locations."
"There are at least three in the Overworld that exist but are completely unused"
"Two on the tower of babil"
"And the back half of mist (town)"
"Also in the underworld, there are several trigger points for the tanks to attack the tower, easily repurposed"
Per b0ardface's and chillyfeez's info above, this means that the trigger data for the overworld map is:
65 9C 24 10 1E 66 9C 24 10 1E 65 9D 24 10 1E 66 9D 24 10 1E 64 9D 00 10 1E 64 9E 00 10 1E 67 9D 00 10 1E 67 9E 00 10 1E 4C 84 6C 02 1C 54 77 6C 9B 03 60 77 01 43 10 61 77 01 DC 10 7D 68 02 0F 1E 8A 53 6F 1A 1D 8A 4D 73 98 09 86 48 74 90 09 7D 42 76 90 0B 77 3E FF 10 00 76 3A 25 10 1E 77 3A 25 10 1E 76 39 25 10 1E 77 39 25 10 1E 88 38 77 8F 04 98 31 7E 0F 1C A0 31 80 15 1E D6 3A 26 0F 1D D7 3A 26 0F 1D D6 39 26 0F 1D D7 39 26 0F 1D DD 38 FF 2B 00 9A C7 03 10 1F 9B C7 03 10 1F DA C7 84 14 1F 22 52 27 10 1D 23 52 27 10 1D 22 51 27 10 1D 23 51 27 10 1D 23 53 05 10 1C 23 54 05 10 1C 24 54 05 10 1C 4A 35 8C 85 07 2D EB 28 10 1F 2E EB 28 10 1F 2D EC 28 10 1F 2E EC 28 10 1F 18 E7 C7 8A 04 68 D7 06 10 1F 69 D8 06 10 1F D2 82 04 11 1E DB 88 A0 07 14 21 DB B5 0C 05 22 DB C0 8C 11 E4 2F CF 08 0B D5 D1 D1 08 0B 59 A3 D2 08 0B 22 65 D3 08 0B 56 4F D4 08 0B 29 35 21 08 1E
...and the trigger data for the underworld map is:
63 52 07 0F 1E 64 52 07 0F 1E 63 51 07 0F 1E 64 51 07 0F 1E 5B 53 0F 03 0E 30 0F FF 58 00 31 0F FF 58 00 68 7B 00 06 0B 3E 79 01 11 1B 3F 79 01 11 1B 3F 7A 01 11 1B 0D 0E 45 90 02 2E 6D 44 04 0A 1B 56 36 91 0A 37 14 FF 36 00 36 11 FF 36 00 33 10 FF 36 00
...and the trigger data for the lunar map is:
3D 17 5A 88 07 1C 19 60 10 1C 12 14 63 0C 1E 12 0E 63 93 05 29 18 64 95 06 28 1C 64 09 19 21 27 65 0A 10
Also, Yousei's notes (for headered v1.0) state:
D0060-D0065 World Trigger Pointers
D0066-D01FF World Trigger Data (*2)
So subtracting 0x200 for the header, these would be:
CFE60-CFE65 World Trigger Pointers
CFE66-CFFFF World Trigger Data (*2)
The data (above) is in five-byte pieces.
Distilling the data I got from b0ardface, chillyfeez, and Aexoden on the subject, and adding what I figured out with a hex editor, Yousei's editor, and Pinkpuff's ff4kster:
The data for world map triggers is at CFE60-CFFFF.
The first six bytes at CFE60 contain the relative offsets (from CFE66) for Overworld, Underworld, and Lunar world maps:
00 00 22 01 77 01
The Overworld map trigger data starts at CFE66, so its relative offset is 0.
The Underworld map trigger data starts at CFF88, so its relative offset is 0x0122.
The Lunar map trigger data starts at CFFDD, so its relative offset is 0x0177.
(these offsets are relative to the beginning of this trigger data, at 0xCFE66)
Each trigger is five bytes in size.
For example, here's the one for Cave Magnes:
4A 35 8C 85 07
According to Yousei's editor, it's at x74, y53. In hex, that's 4A, 35.
ff4kster says Cave Magnes 1F is grid index 140. In hex, that's 8C. We'll assume the grid index matches the map index, which isn't always true apparently.
b0ardface said:
"Second last byte contains both X coordinate (lower 6 bits) and facing direction upon arrival (top 2 bits)"
...and the tile you arrive at in Cave Magnes 1F (looking at it with ff4kster) is 5,7.
Assuming the last byte is the Y position, this means that 0x80 is the facing direction value.
Aexoden said:
"Yes, so shift the bits right 6 times"
"128 / 2 ^ 6 = 2"
"Or just think of the top two bits being "10"
"So the direction possibilities are going to be 0x00, 0x40, 0x80, 0xC0"
"up, right, down, left"
In summary, Cave Magnes overworld map trigger is at 74, 35; it teleports you to map 140 (Cave Magnes 1F); and in that map, it places you at 5,7, facing down.
This works slightly differently for world map event triggers (as opposed to teleport triggers as described above).
World map event triggers still use the first two bytes for coordinates on the world map, but the third byte will be 0xFF, the fourth byte will be the event code, and the fifth byte will be 0x00.
For example, here is the Damcyan Bombing event:
77 3E FF 10 00
It's located at X coordinate 0x77, Y coordinate 0x3E, it's an event (0xFF), its event code is 0x10 (Damcyan Bombing event), and the last byte is unused because it's an event trigger.
Note: Teleport triggers must use the coordinates of a trigger-type tile. Using a tool like FF4MapEdit, you can view which tiles are trigger-type tiles. These are analogous to the trigger tiles seen in ff4kster with a red square around them or red symbols in the middle of them.
