Overview

Terrain files (*.xxw) represent a single terrain to be used by a world. This format was used in Star Wars: The Clone Wars.
THIS IS HEAVY WORK IN PROGRESS.

Terrain Header

The Terrain Header is always 1152 bytes in length.

Terrain Blocks

The Terrain Header is always 2821 bytes in length.

Name Data Type Size
Height signed short Terrain size * Terrain size * 2
Height value for every point on the grid. This value will be multiplied with the map scale multiplier.
