Game 2048 engine

The current engine can handle a NxN (N > 2) field with the numbers 0,2,4,8,16,...,2^M (M < 53).

Field input format example: [ [0,2,0,4], [4,0,0,0], [0,0,0,0], [8,0,16,16], ]

To make a move, you need to send one of the four directions U, D, L or R.

Move input format example: "L" Moves input format example: ["L", "R", "U", "U", "D"]

Move processing example: [0, 4, 4, 4 ] "L" -> [8, 4, 0, 0]

As a result of the engines processing, the passed field will be changed according to the passed moves.

Typical use case:

import {createEngine} from 'game2048engine'

...

const field = [
    [0,2,0,4],
    [4,0,0,0],
    [0,0,0,0],
    [8,0,16,16],
]

const engine4x4 = createEngine(4);

while(true) {
    const move = readInput();
    engine4x4.safeApplyMove(field, move); // or just call engine4x4.applyMove(field, move) if we want to avoid arguments validation
    addMoreValues(field);
    updateDisplay(field);
}
