This program will read scenario files (.sce) and render the maps.

The following games are supported:

• The Operational Art of War: Century of Warfare
• The Operational Art of War III
• The Operational Art of War IV

Command-Line Usage

./TOAWMap.exe -input=[input filename] -output=[output filename]

Example

./TOAWMap.exe -input=scenario.sce -output=scenario.png

About

There have been many maps generated for The Operational Art of War (TOAW) series, but there isn't much information on the file formats and there is no way to parse the data. This project analyzes the different games and you can see how there is a lot of overlap between the various file formats.

TOAW Game Version Notes

The Operational Art of War IV (TOAW4) uses gzip to compress the files. The file will begin with the gzip header, where the magic number is 0x1f8b and the compression method is 08 for DEFLATE.

TOAW3 and earlier games use PKWare Compression Library to compress each of the blocks. The header will begin with "TOAC".

Tile Data

In the decompressed blocks array, this is the block with index 1, which would be the 2nd element starting from index 0.

In TOAW4, the maximum map size is 700x700. In TOAW3 and earlier games, the maximum map size is either 300x300 or 100x100.

Each tile is 47 bytes, which is represented as a byte array in the code.

5	Hills tile flag
