This folder contains the information used for tiles in the battlescape view, both statistical and graphical.<br>
+
{{tocright}}This folder contains the information used for tiles in ''EU's'' battlescape view, both statistical and graphical.
−
<br>
 
−
Each of the three files used for each tileset contains a variable amount of records. PCK files and their respective TAB files should always contain an equal amount of records.<br>
 
−
==MCD==
 
−
Files made up of a variable amount of records, each of 62 bytes.
 
  
−
Things to search for:
+
These are divided up into "sets" made of three files: An [[MCD]] file, which defines the tiles for that set, and a [[Image_Formats#PCK|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)).
−
- Stun caused by explosion.
 
  
−
''- Stun caused by explosion comes from mcd[54], when the setting for explosive type is Smoke. - [[User:Hobbes|Hobbes]]''
+
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.
  
−
'''0-7:''' Animation of the tile.
+
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 eight bytes refer to images on the PCK files which are used in a sequence (from the first byte to the last) to animate tiles. This animation is used by several tiles on both games, such as doors, bubbles on TFTD, blinking lifts, etc.
+
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]].
  
−
'''8-19:''' Loft of the tile. 12 values, each references into [[LOFTEMPS.DAT]] file.
 
  
−
Each record is a 16x16 grid, which are stacked one over the other, with byte 8 being the bottom. Used to create a 3D map of the tile, for LOS.
+
==Contents==
  
−
'''20-21:''' Reference into [[SCANG.DAT]] file. [20] + [21] * 256 + 35 = offset. Used for top-down map.
+
The size of an [[MCD| MCD]] file is equal to the amount of records it holds times 62 bytes.
  
−
'''22-29:'''
+
The size of a TAB file is equal to the amount of images it indexes times 2 bytes.
  
−
'''30:''' Boolean: Is sliding door?
+
PCK files contain RLE-compressed image data and are of unpredictable sizes.
  
−
'''31:''' Boolean: Can't be seen through?

−
''You've noticed a nice point there, which I think has to do with the fact that aliens can be killed with explosions happening from the 1 setting on [54] but not X-COM units. I've just tested this by moving unarmored soldiers right next to the gas pumps and shooting at them. Like you said, on UFO the objects explode with a 1 on [54], if [55]>0. But on my terrain mods I've barrels with a 0 setting on [54] and [55]>0 and those will kill X-COM units when they are hit and explode. Thus, the 0 HE and 1 Smoke designations are correct, it's only that for the aliens the Smoke explosion will hurt/kill them.

PCK decoding is fairly simple: the first byte in the data stream tells you how many rows you should skip. Then you just draw each byte afterwards directly onto the screen (which should be using a 256 color palette).<br>

Values 254/255 are not to be drawn. If you encounter a byte with a value of 254 (FE), then the next byte tells you how many pixils you should skip. If you encounter a byte with a value of 255 (FF), then you're done.<br>

While simplistic, I've found that the best way to use PCK files is to store them 'as is', then decode them straight onto the screen as needed (as opposed to pre-rendering them and storing the completed graphics in memory). This makes lighting effects that much easier to implement.

Latest revision as of 03:35, 23 July 2013

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.
