til

Overview ¶

Package til implements access to TIL files.

The TIL file of each level (e.g. "levels/l1data/l1.til") specifies how to arrange dungeon pieces - the miniture tiles constructed from the level's MIN file - in order to form tiles. A tile consists of 4 dungeon pieces.

Below follows a pseudo-code description of the TIL file format.

// A TIL file consists of a sequence of tile definitions.
type TIL []Tile

// A Tile consists of four dungeon pieces (top, right, left, bottom),
// forming a square.
//
//     /\        1
//    /\/\      3 2
//    \/\/       4
//     \/
type Tile struct {
   // Dungeon piece ID at the top of the tile.
   Top uint16
   // Dungeon piece ID at the right of the tile.
   Right uint16
   // Dungeon piece ID at the left of the tile.
   Left uint16
   // Dungeon piece ID at the bottom of the tile.
   Bottom uint16
