Games	Fury of the Furries Pac-In-Time

Fury of the Furries maps contain the static background and landscape for the level, collectable coins, time extensions and extra lives and destructible bricks. They also contain the 'scripting for the game play itself', this is in the form of the definitions of the sprites that interact with the player character. There are up to 10 sprites in the level, each having up to 10 states. Triggers are defined for switching between states, and for the player and or sprites to switch on or off other game-play elements.

The file itself is run-length encoded, and after decompression is always a fixed length. Generally unused elements within the game are marked by the UINT16LE value 0xFFFF.

File Formats

RLE Compressed File Format

Data Type	Name	Description
FOURCC	header	Appears to be a header with version number. Most files decompress to an object 25518 bytes in length, but a handful of files are shorter, and appear to be earlier versions. byte is the shortest, at 25432 bytes, the last entry is the time field. byt1 and byt3 are 25482 bytes long, and include currents. byt4 is 25518, it's the version seen for the vast majority of the files, and includes all the fields after the currents.
UINT16LE	length	Number of bytes in section. if zero then stop decompressing. if less than 0x7D00 then use the following length bytes from the input. otherwise use the following byte from the input (length - 0x7D00) times. compressed and uncompressed sections always alternate, even if this makes the packing less efficient. This means that if you have two adjacent runs, There will be at least 1 character represented as uncompressed.
...	etc	continue with another 'length' until the final file size is achieved (25,518 bytes), or you read a 0 length.

The file should end with a zero length section. i.e. two bytes of 0.

Uncompressed File Format

FILE Format

Data Type	Name	Description
UINT16LE	mapWidth	Width of the playable area (in tiles) between 20 and 78.
UINT16LE	mapHeight	Height of the playable area (in tiles) between 13 and 51. The maximum number of tiles in a game is 1024. This places constraints on the width and height. The minimum width is 20 to match the viewport size of 320 pixels, and this constrains the height to 51 (20 × 51 = 1020). The minimum height is 13 to match the viewport size of 200 pixels, and this constrains the width to 78 (13 × 78 = 1014). Any other combination of width and height is possible so long as it meets these constraints.
UINT8[2][78 × 51]	tileIndex	Pairs of coordinates into a LBM Format DEC file containing the tiles.
UINT16LE	decFile	The DEC file number less one. i.e. a value of 3 indicates DECOR04.LBM.
UINT16LE	startLeft	The center of the starting position for the player character from the left of the level, less 16 pixels.
UINT16LE	startTop	The center of starting position for the player character from the top of the level, less 16 pixels.
UINT16LE	foregroundPaletteIndex	The index of the first palette entry to be regarded as foreground. The palette for the DEC file has 16 colours and they are used in a particular order. The first is always black and is background (i.e. the player character is not blocked by this colour) The next 4 usually dark versions of yellow, red, green and blue and are used for the shadow colour of the player character sprite, in the 4 different forms that the player can take. The next colour (colour 5 in the palette) is the bright colour of the player character, and will be swapped out as the player changes form. The remaining colours a chosen to suit the needs of the stage of the game (desert, forest, mountains etc). Generally the lower colours are regarded as background, and the upper colours as foreground, and this is used in the collision detection for the player and the landscape.

Notes

There are 10 different stages in the game, and correspondingly 10 different tile and sprite sets.

The tile images for the backgrounds and landscape are stored in the DEC directory, in image files which are in LBM Format. These files are named DECORxx.LBM where xx is specified by the decFile field of the main structure.

The sprite images are stored in the SPR directory, in image files which are in LBM Format. These files are named SPRxxn where xx is specified by the decFile field of the main structure, and n is specified by the spriteMap field in the main structure.

The sprites can be of varying sizes, the FRAME data structure describes the bounding box in pixels within the sprite image file. If the sprite requires a transparency mask, then this mask will be a rectangular region with the same size as the sprite, and placed in the image file immediately below the sprite.

Within the tile image file, all the tiles are 16 × 16 pixels, tiles are referenced in the main file structure as a pair of byte coordinates, giving the X and Y position in tiles within the image file.

Certain tiles in the image file have special meaning.

The tile at 0,1 is a coin. If the player touches this tile in the level, they will gain a coin, and the tile will be swapped out for the tile at 0,0 which is always empty.

The tile at 0,2 is an extra life. If the player touches this tile in the level, they will gain an extra life, and the tile will be swapped out for the tile at 0,0.

The tile at 0,3 is a time extension. If the player touches this tile in the level, they will gain an extra 30 seconds on the clock, and the tile will be swapped out for the tile at 0,0.

All the remaining tiles on rows 0, 1 and 2 in the map are destructible tiles. The red form of the player can chew through the scenery. Chewing a tile from row 0 will cause that tile to be swapped out with the tile immediately below it in row 1. Chewing a tile from row 1 will cause that tile to be swapped out with the tile immediately below it in row 2. Chewing a tile from row 2 will cause that tile to be swapped out with the tile at 0,0, which is empty, so the player can then get through the gap created. Typically the tiles in these rows depict a gradually degraded state, you can have tiles that require more or less action to destroy them, by choosing from the three rows. Often the top row tiles are visually indistinguishable from some other non-destructible tiles in the tileset, allowing you to hide destructible tiles.
