TERRAIN

This folder contains the information used for tiles in EU's battlescape view, both statistical and graphical.

These are divided up into "sets" made of three files: An MCD file, which defines the tiles for that set, and a PCK file accompanied by a TAB file, which together define the image data that represents said tiles on-screen (note that PCK files always have the same amount of records as their respective TAB files, though MCD files may have a different figure (as some tiles animate and hence use multiple sprites, and some tiles use the same sprites as others but at a different height offset)).

Each "set" stored here will be part of an even larger "terrain set", which will have corresponding files in both the MAPS folder and the ROUTES folder.

The maximum amount of MCD records allowed in any given fully-built map is 256. This is also the highest count used in game, achieved by sending a Skyranger or Interceptor to deal with a Harvester or Supply Ship in Forest Terrain.

The maximum amount of PCK records allowed is as yet unknown. The highest count used in game is 329, achieved by sending a Skyranger or Interceptor to deal with a Terror Ship or Battleship in Arctic Terrain.


Contents

The size of an MCD file is equal to the amount of records it holds times 62 bytes.

The size of a TAB file is equal to the amount of images it indexes times 2 bytes.

PCK files contain RLE-compressed image data and are of unpredictable sizes.
