==Info==

WMSETxx.obj (where xx may refer to gr,us,it,fr,sp) is a multi-data world map file containing many core functions and 3D objects. This file contains almost everything: sounds, scripts, dialogs, texts, textures, models- all contained in one file. Main differences between en/it/gr/sp/fr are localized dialogs, so next sections have different offsets. Offsets before this are all the same. [[FF8/WorldMap_wmset|Wmset.obj]] is probably never used in-game and is leftover. Dialogs in lang-en/wmset.obj are in english, but the file is different from wmsetus.obj.

==General structure==

WMSETxx.obj is made from 48 sections. File starts with header, that has 48*4 bytes. Every offset is 4 bytes long.

{| border="1" cellspacing="1" cellpadding="3" align="center" style="border: 1px solid black; border-collapse: collapse;"
! style="background:rgb(204,204,204)" | Offset

|-
| 0
| 4 bytes
| Section 1
|-
| SectNmbr * 4
| 4 bytes
| Section SectNmbr
|}

The last section is offset 188.

=== Section 1: World map encounter data supplier ===

'''EncounterIdSupplierDataProvider_Entry''':

| regionID
|-
| 1

| groundID
|-
| 2

| ESI*
|-
| 3
| Byte
| unused
|}

* ESI is the name of the register that holds the third byte parameter of section1. It is used later to determine the encounter. When the character makes a step on worldmap, the game loops through whole section1 data and tests:

if the character is walking on groundID and regionID, if yes, then ESI is our multiplier to section4 containing encounters. Example entry:

00 06 00 00:

If Squall is in region = 0 and walks on ground with ID 6 (as far as I remember it's Balamb Plains or forest) then get encounters from section4 that start at 0*8; Other example:

04 1B 24 00:

If Squall is in region = 4 and walks on ground with ID 0x1B, then get encounters from section4 that starts at 0x24*8 = 288

That way the engine can play encounter based on place you are, because if you're walking on Balamb beach, then engine should play encounter with beach, not snow plains. That's why if you change the for one map portion you can totally erase encounters in this region, because in example region 4 that may be Centra regions does not contain any BalambPlains, so there is no entry in section1 and therefore the engine finds the region encounters, but doesn't find the encounter entries for BalambPlainsGround in Centra ruins (this is totally an example).

=== Section 2: World map Regions ===

Nothing much to write here.
32x24 world map. Just open it via hexEditor.
It's just bitmap (you can even convert bytes to image and mini worldmap will show)
Every single byte is regionID used for example in section1 for encounters.

=== Section 3: UNKNOWN ===

UNKNOWN

=== Section 4: World Map Encounters ===

{| border="1" cellspacing="1" cellpadding="3" align="center" style="border: 1px solid black; border-collapse: collapse;"
! style="background:rgb(204,204,204)" | Offset
! style="background:rgb(204,204,204)" | Length
! style="background:rgb(204,204,204)" | Description
|-
| section1.ESI * 8
| 8 bytes
| 2 * 4 bytes of encounters from scene.out
|}

It's as simple as that:
Squall makes step on worldmap, game gets Squall position and tests it with section2 containing region, then loops through section1 and tests groundID and regionID to find ESI multiplier, if random number generates battle, then game gets to section4 using ESI determined earlier with Squall step on world map and plays randomly one of the eight encounters (because one ESI/encounterEntry is 8 bytes, where first four are the most common, other 2 medium and last 2 rarest)

=== Section 5: UNUSED ===
Unused in-game

=== Section 6: World Map Encounters (after Lunar Cry) ===

Same as Section 4, but patched with Lunar Cry encounters.

=== Section 7-8: roads, train track, bridge ===

Related with Section 39. Maybe scripts in section 8. (like sections 10, 12 and 32)

Script format (ScriptsCount must be guessed):

{| border="1" cellspacing="1" cellpadding="3" align="center" style="border: 1px solid black; border-collapse: collapse;"
! style="background:rgb(204,204,204)" | Offset
! style="background:rgb(204,204,204)" | Length
! style="background:rgb(204,204,204)" | Description
|-
| 0
| 4 * ScriptsCount + 4
| List of script positions, not always sorted (ended with 0x00000000)
|-
| 4 * ScriptsCount + 4
| Varies + 4
| Scripts data (ended with 0x00000000)
|}

In script data you have 4-bytes opcodes, the first byte is the identifier, and the last two bytes are the parameter (the second by is always 0xFF).
Scripts always start with 0x01 opcode, and finish with 0x16 opcode. There is always one 0x04 opcode inside.
For now most is unknown, I only understood that 0x2B opcode refer to scene ID in its parameter (you can find UFO, Koyo-K and Lac Obel battles in Section 32).

=== Section 9: UNKNOWN ===

=== Section 10-11: UNKNOWN (Related to Squall model) ===

Maybe scripts in section 10. (like sections 8, 12 and 32)

=== Section 12-13: UNKNOWN ===

Maybe scripts in section 12. (like sections 8, 10 and 32)

=== Section 14: Side quests texts/tialogs ===

This section provides dialogs on world map used in side quests.

This section starts with header pointing to '''relative''' offsets to dialog/text portions.

=== Section 29: World map "water block"===

Section 29 is a duplicate segment from "full" water block (not segment!) used in world map (wmx.obj).

==== Usage ====

<s>Whenever landing or entering ragnarok, the engine does not load segments from wmx.obj until the transition is done.</s> Whenever transforming viewport at certain speed, the engine can't keep up with loading the new segments/blocks. The areas that are not loaded but should be rendered in the same time are filled with this block. This can be seen when the camera view is set so that it rotates during ragnarok entering/exiting transition or placing character to different area.

X = rowBlockAmount, which is 4 times segment amount so 4 * 32 = 128 or 0x80. The last bit tells which row of the two we are on, first or second. The range of top row is from 0x00 - 0x7F and second row's 0x80 - 0xFF.

Y is incremented whenever X goes over 0xFF.

WMSETxx.obj (where xx may refer to gr,us,it,fr,sp) is a multi-data world map file containing many core functions and 3D objects. This file contains almost everything: sounds, scripts, dialogs, texts, textures, models- all contained in one file. Main differences between en/it/gr/sp/fr are localized dialogs, so next sections have different offsets. Offsets before this are all the same. [[FF8/WorldMap_wmset|Wmset.obj]] is probably never used in-game and is leftover. Dialogs in lang-en/wmset.obj are in english, but the file is different from wmsetus.obj.

* ESI is the name of the register that holds the third byte parameter of section1. It is used later to determine the encounter. When the character makes a step on worldmap, the game loops through whole section1 data and tests:

if the character is walking on groundID and regionID, if yes, then ESI is our multiplier to section4 containing encounters. Example entry:

00 06 00 00:

If Squall is in region = 0 and walks on ground with ID 6 (as far as I remember it's Balamb Plains or forest) then get encounters from section4 that start at 0*8; Other example:

04 1B 24 00:

If Squall is in region = 4 and walks on ground with ID 0x1B, then get encounters from section4 that starts at 0x24*8 = 288

That way the engine can play encounter based on place you are, because if you're walking on Balamb beach, then engine should play encounter with beach, not snow plains. That's why if you change the for one map portion you can totally erase encounters in this region, because in example region 4 that may be Centra regions does not contain any BalambPlains, so there is no entry in section1 and therefore the engine finds the region encounters, but doesn't find the encounter entries for BalambPlainsGround in Centra ruins (this is totally an example).

=== Section 2: World map Regions ===

Nothing much to write here.
32x24 world map. Just open it via hexEditor.
It's just bitmap (you can even convert bytes to image and mini worldmap will show)
Every single byte is regionID used for example in section1 for encounters.

=== Section 4: World Map Encounters ===

| section1.ESI * 8
| 8 bytes
| 2 * 4 bytes of encounters from scene.out
|}

It's as simple as that:
Squall makes step on worldmap, game gets Squall position and tests it with section2 containing region, then loops through section1 and tests groundID and regionID to find ESI multiplier, if random number generates battle, then game gets to section4 using ESI determined earlier with Squall step on world map and plays randomly one of the eight encounters (because one ESI/encounterEntry is 8 bytes, where first four are the most common, other 2 medium and last 2 rarest)

=== Section 5: UNUSED ===
Unused in-game

=== Section 6: World Map Encounters (after Lunar Cry) ===

Same as Section 4, but patched with Lunar Cry encounters.

=== Section 7-8: roads, train track, bridge ===

Related with Section 39. Maybe scripts in section 8. (like sections 10, 12 and 32)

Script format (ScriptsCount must be guessed):

|-
| 4 * ScriptsCount + 4
| Varies + 4
| Scripts data (ended with 0x00000000)
|}

In script data you have 4-bytes opcodes, the first byte is the identifier, and the last two bytes are the parameter (the second by is always 0xFF).
Scripts always start with 0x01 opcode, and finish with 0x16 opcode. There is always one 0x04 opcode inside.
For now most is unknown, I only understood that 0x2B opcode refer to scene ID in its parameter (you can find UFO, Koyo-K and Lac Obel battles in Section 32).

=== Section 9: UNKNOWN ===

=== Section 10-11: UNKNOWN (Related to Squall model) ===

Maybe scripts in section 10. (like sections 8, 12 and 32)

=== Section 12-13: UNKNOWN ===

Maybe scripts in section 12. (like sections 8, 10 and 32)

=== Section 14: Side quests texts/tialogs ===

This section provides dialogs on world map used in side quests.

This section starts with header pointing to '''relative''' offsets to dialog/text portions.

=== Section 29: World map "water block"===

Section 29 is a duplicate segment from "full" water block (not segment!) used in world map (wmx.obj).

==== Usage ====

<s>Whenever landing or entering ragnarok, the engine does not load segments from wmx.obj until the transition is done.</s> Whenever transforming viewport at certain speed, the engine can't keep up with loading the new segments/blocks. The areas that are not loaded but should be rendered in the same time are filled with this block. This can be seen when the camera view is set so that it rotates during ragnarok entering/exiting transition or placing character to different area.

X = rowBlockAmount, which is 4 times segment amount so 4 * 32 = 128 or 0x80. The last bit tells which row of the two we are on, first or second. The range of top row is from 0x00 - 0x7F and second row's 0x80 - 0xFF.

Y is incremented whenever X goes over 0xFF.
