Wrp File Format - 8WVR
Introduction
- To do...
Legend
| Type | Description |
|---|---|
| byte | 8 bit (1 byte) |
| short | 16 bit signed short (2 bytes) |
| int | 32 bit signed integer (4 bytes) |
| float | 32 bit signed single precision floating point value (4 bytes) |
| asciiz | Null terminated (0x00) variable length ascii string |
| ascii | fixed length ascii string |
Although technically there should never be negetive values for many of the 16 bit & 32 bit values, it's 'safer' in programming terms to use signed datatypes as opposed to unsigned datatypes.
File Format
- The following is a mix of pseudo-code and structure references that could be used to describe the file format of 8WVR.wrp game island.
- Any naming definitions or naming conventions used may or may not be accurate.
- This file format is principally used with Armed Assault.

Notes
- The 'Elevations' array extends from Top-Left to Bottom-Right;
- The 'TextureGridMaterials' array is a mapping of .rvmat material files to TextureGrid cells/tiles.
- The 'Objects' array will always have at least 1 entry. Denoting the 'center' of the map.
- The 'Objects' array is the last structure in the file and the 'NoOfObjects' is a variable amount and extends from the starting offset of the structure to the EndOfFile.
- The 'TransformMatrix' for a given object is a standard 4,3 transform matrix which when decomposed determines the objects x,y,z position, scale & orientation.
