engine-2048

This is a simple library which gives 2048 backend functionality. e.g the generation of a grid and moving of tiles.

Usage

The data structure

The grid datastructure is keyed by the rows by letter and name and empty slots are set as nil. e.g

{:a1 nil :a2 2 :a3 nil :a4 4 :b1 nil :b2 2 :b3 8 :b4 4 :c1 2 :c2 8 :c3 4 :c4 nil :d1 4 :d2 8 :d3 nil :d4 nil}

The grid has a map as metadata containing boolean values for keys:

• :over? - True whether the game is over (unable to move in any direction)
• :left?/:right?/:up?/:down? - True when it is possible to move in the said direction

Functions:

(generate-grid) - returns a grid as the data structure described above

(grid-move :direction grid) - moves the grid in the following direction, generates a new random tile.

• :direction can be any of the following :left/:right/:up/:down to move in the following direction
• grid needs to be the previous grid
