Sonic Adventure DX: PC/Level Data Locations
From Sonic Retro
Disclaimer
Each level in Sonic Adventure DX is a compiled C++ file with embedded model data. They are usually similar in structure, but there is technically the possibility that some things may be in different locations for different levels.
LandTable header format
| Offset | Type | Description |
|---|---|---|
| 0 | Short | COL Count |
| 2 | Short | Anim Count |
| 4 | Int | Some type of flag, usually 12, 13 indicates the presence of animations. |
| 8 | Float | Unknown, usually 3000 |
| C | Pointer | COL List |
| 10 | Pointer | Anim List |
| 14 | Pointer | Texture file name. Optional, possibly unused. |
| 18 | Pointer | Texture List |
| 1C | Int | Unknown |
| 20 | Int | Unknown |
COL Format
The name COL is an antiquated misnomer, but for lack of a better name, it stuck. This data struct is a reference for loading a level model. It's 0x24 bytes long and works as follows:
| Offset | Type | Description |
|---|---|---|
| 0 | Float[3] | Center of collision sphere |
| C | Float | Radius of collision sphere |
| 10 | 8 Bytes | Padding? |
| 18 | Pointer | Model (OBJECT Struct) |
| 1C | Int | Unknown |
| 20 | Int | Surface Flags (see below) |
Surface Flags
These flags are not entirely figured out yet, but here's what is known for sure: 0x00000001 = Solid 0x00000002 = Water (overrides solid flag, makes surface transparent) 0x00000004 = No Friction 0x00000008 = No Acceleration 0x00000080 = Increased Acceleration 0x00000100 = Diggable 0x00001000 = Unclimbable 0x00010000 = Hurt 0x00100000 = Footprints 0x80000000 = Visible
Listing of Header locations
This listing isn't for the actual start of the header, that location hasn't been determined. Since the major interest in editing levels is editing their geometry, this list will (for now) refer to the geometry loading index. These use the COL format as described above. Also, when this list was being created, the location selection was a little inconsistent. This has since been corrected, and the data has been reformatted to facilitate the use of available level rippers.
