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.
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:
struct COL float center[3]; // Center of the visibility/collision sphere. float radius; // Could be diameter. dword null[2]; // for alignment purposes dword SEG; // points to SEG struct dword null; Short col; // determines solidity Short surf_flag; // determines visibility
Surface Flags
First byte:
- 1x = can land on
- 2x = push
- 3x = push
- 4x = Kill sonic?
- 5x = no alpha, no col
- 6x = water
- 7x = lighting
- 8x = Stage Specific on/off (EC footprints)
- 9x = normal surf
Second Byte:
- x0 = normal
- x1 = hurt
- x2 = low traction
- x3 = hurt
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, sometimes the address given is for the end of the list, other times it is the address that points to the beginning of the list. Either way, they're within a tolerance of 0x0c of eachother, so don't use these addresses in a program, if you're coding a utility, please open a hex editor and make sure your address is accurate first.
