Behind 2048
Maybe you’ve already heard about the simple and addictive game, 2048 (read more about it here ). In this task we will look behind the scenes and try to recreate its basic movement functionality.
[[0, 1, 2, 3], [4, 5, 6, 7], [8, 9, 10, 11], [12, 13, 14, 15]]
[[0, 1, 2, 3], [4, 5, 6, 7], [8, 9, 10, 11], [12, 13, 14, 15]]At the beginning, there's already two numbers on the board.
You are given a game state represented as a 4x4 matrix with numbers that are powers of 2. Players move in a direction (up, down, left, right). You should return the game state after this move.
[['U','W','I','N'], ['U','W','I','N'], ['U','W','I','N'], ['U','W','I','N']]
[['U','W','I','N'], ['U','W','I','N'], ['U','W','I','N'], ['U','W','I','N']]If the game is lose, i.e. nothing change after the player move and there is not a empty spot, then return the losing matrix:
[['G','A','M','E'], ['O','V','E','R'], ['G','A','M','E'], ['O','V','E','R']]
[['G','A','M','E'], ['O','V','E','R'], ['G','A','M','E'], ['O','V','E','R']]
Input: A game state as a list of lists with integers and player's move as a string ('up', 'down', 'left' or 'right').
Output: The game state after player's move as a list of lists with integers or letters.
How it is used: This can be used as a bases for further adding GUI to the python version of the 2048 game.
Example:
move2048([[0, 2, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0], [0, 2, 0, 0]], 'up') == [[0, 4, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 2]] move2048([[4, 0, 0, 0], [0, 4, 0, 0], [0, 0, 0, 0], [0, 0, 8, 8]], 'right') == [[0, 0, 0, 4], [0, 0, 0, 4], [0, 0, 0, 0], [0, 0, 2, 16]] move2048([[2, 0, 2, 2], [0, 4, 4, 4], [8, 8, 8, 16], [0, 0, 0, 0]], 'right') == [[0, 0, 2, 4], [0, 0, 4, 8], [0, 8, 16, 16], [0, 0, 0, 2]] move2048([[256, 0, 256, 4], [16, 8, 8, 0], [32, 32, 32, 32], [4, 4, 2, 2]], 'right') == [[0, 0, 512, 4], [0, 0, 16, 16], [0, 0, 64, 64], [0, 2, 8, 4]] move2048([[4, 4, 0, 0], [0, 4, 1024, 0], [0, 256, 0, 256], [0, 1024, 1024, 8]], 'down') == [['U', 'W', 'I', 'N'], ['U', 'W', 'I', 'N'], ['U', 'W', 'I', 'N'], ['U', 'W', 'I', 'N']] move2048([[2, 4, 8, 16], [32, 64, 128, 256], [512, 1024, 2, 4], [8, 16, 32, 64]], 'left') == [['G', 'A', 'M', 'E'], ['O', 'V', 'E', 'R'], ['G', 'A', 'M', 'E'], ['O', 'V', 'E', 'R']]
Preconditions:
len(state) == 4
all(len(row) == 4 for row in state)
all(all(x in (0, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024) for x in row) for row in state)
CheckiO Extensions allow you to use local files to solve missions. More info in a blog post.
In order to install CheckiO client you'll need installed Python (version at least 3.8)
Install CheckiO Client first:
pip3 install checkio_client
Configure your tool
checkio --domain=py config --key=
Sync solutions into your local folder
checkio sync
(in beta testing) Launch local server so your browser can use it and sync solution between local file end extension on the fly. (doesn't work for safari)
checkio serv -d
Alternatevly, you can install Chrome extension or FF addon
checkio install-plugin
checkio install-plugin --ff
checkio install-plugin --chromium
Read more here about other functionality that the checkio client provides. Feel free to submit an issue in case of any difficulties.
