Reign of Chaos Format

Header

Type	Description
char[4]	file ID = "W3do"
int	file version = 7
int	unknown (usually set to [09 00 00 00]h, rarely [07 00 00 00]h)
int	number of trees defined

Data

Each tree is defined by a block of 42 bytes organized like this.

Type	Description
char[4]	Tree ID (can be found in the file "Units\DestructableData.slk")
int	Variation (little endian)
float	Tree X coordinate on the map
float	Tree Y coordinate on the map
float	Tree Z coordinate on the map
float	Tree angle (radian angle value)(degree = radian*180/pi)
float	Tree X scale
float	Tree Y scale
float	Tree Z scale
byte	Tree flags (see below)
byte	Tree life (integer stored in %, 100% is 0x64, 170% is 0xAA for example)
int	Tree ID number in the World Editor (little endian) (each tree has a different one)

Flags

• 0 = invisible and non-solid tree
• 1 = visible but non-solid tree
• 2 = normal tree (visible and solid)

To sum up how it looks:

tt tt tt tt vv vv vv vv xx xx xx xx yy yy yy yy zz zz zz zz aa aa aa aa xs xs xs xs ys ys ys ys zs
zs zs zs ff ll dd dd dd dd

The values are:

• tt: type
• vv: variation
• xx: x coordinate
• yy: y coordinate
• zz: z coordinates
• aa: rotation angle
• xs: x scale
• ys: y scale
• zs: z scale
• ff: flags
• ll: life
• dd: doodad number in the editor

Example (this is the second tree of Legend):

4C 54 6C 74 08 00 00 00 00 00 74 45 00 00 70 44 00 10 24 44 E5 CB 96 40 98 85 98 3F 98 85 98 3F 98 85 98 3F 02 64 8D 01 00 00

4C 54 6C 74 --> LTlt (tree type)
08 00 00 00 --> 00000008 = variation #8 (changes the shape of the tree)
00 00 74 45 --> X=3904.
00 00 70 44 --> Y=960.
00 10 24 44 --> Z=656.25
E5 CB 96 40 --> Angle (float value=4.7123895, angle=270°)
98 85 98 3F --> X_Scale=1.191577
98 85 98 3F --> Y_Scale=1.191577
98 85 98 3F --> Z_Scale=1.191577
02 --> tree is solid and selectable
64 --> life=100% of default tree life
8D 01 00 00 --> 0000018D=397, tree number 397

After the last tree definition, there are 4 bytes set to '0' (dunno if it's a version or not).

Type	Description
int	N times "special" doodads ("special" like cliffs,...)

Then N times a special doodad structure (16 bytes each):

Type	Description
char[4]	doodad ID
byte[4]	? (0)
int	X? (w3e coordinates)
int	Y? (w3e coordinates)

Frozen Throne Format

Header

Type	Description
char[4]	file ID = "W3do"
int	file version = 8
int	unknown ([0B 00 00 00]h)
int	number of trees defined

Data

Each tree is defined by a block of 50 bytes.

Type	Description
char[4]	Tree ID (can be found in the file "Units\DestructableData.slk")
int	Variation (little endian)
float	Tree X coordinate on the map
float	Tree Y coordinate on the map
float	Tree Z coordinate on the map
float	Tree angle (radian angle value)(degree = radian*180/pi)
float	Tree X scale
float	Tree Y scale
float	Tree Z scale
byte	Tree flags (see below)
byte	Tree life (integer stored in %, 100% is 0x64, 170% is 0xAA for example)
int	unknown (-1)
int	unknown (0)
int	Tree ID number in the World Editor (little endian) (each tree has a different one)

Flags

• 0 = invisible and non-solid tree
• 1 = visible but non-solid tree
• 2 = normal tree (visible and solid)

To sum up how it looks:

tt tt tt tt vv vv vv vv xx xx xx xx yy yy yy yy zz zz zz zz aa aa aa aa xs xs xs xs ys ys ys ys zs
zs zs zs ff ll bb bb bb bb cc cc cc cc dd dd dd dd

Where:

• tt: type
• vv: variation
• xx: x coordinate
• yy: y coordinate
• zz: z coordinates
• aa: rotation angle
• xs: x scale
• ys: y scale
• zs: z scale
• ff: flags
• ll: life
• bb: unknown
• cc: unknown
• dd: doodad number in the editor
