TOOLKIT FOR THE R^N GAME

For which people seem to be quite crazy right now...

Based on the works of Gabriele Cirulli, which was inspired by 1024 by Veewo Studio and conceptually similar to Threes by Asher Vollmer.

This code is developed from scratch but is identical in concept and created with an additional agenda of developing an extensible framework for experimenting with the game itself.

{ Play the game }

Features already implemented:

• Multiple game instances one after another in the game area.
• Each game fully customizable with:
  • Variable Mantissa (R, example = 2 for the 2048 game)
  • Variable Winning Exponent (N, example = 11 for the 2048 game)
  • Variable Grid size of the game board (K, example = 4 for the 2048 game)
  • Variable Tile size (T in pixels, example ~100 for the 2048 game)
• Game Generator options panel to create multiple instances of the game with a few clicks and experiment with different game parameters.
• Exposed functions to manipulate the game data through console.

Exposed functions

To experiment without the Game Generator interface, use the browser's JavaScript console itself.

For example, to generate a new game instance, run the following command:

setupNewGame(R, N, K, T);

with suitable values for R, N, K, T.

The accepted range of these values are:

• R: 2 to 10
• N: 2 to 20
• K: 2 to 20
• T: 50 to 300

Each new game instance generation sets the most newly generated game instance to be the current game instance, which is maintained in the global variable currGameIndex which holds the index of the game instance in the gridGame array that holds all the game instances. This is because of the design consideration that keyboard inputs (UP, DOWN, LEFT, RIGHT) should be directed to only one game instance at a time.

To activate keyboard input to a previously created game instance, either use the Game Generator interface to change the Current Game Index (CGI) or simply invoke the setter function setCGI(cgiValue) directly through the browser's console passing the respective game instance's index as the parameter cgiValue to the function. A complementary getter function getCGI() is also available to obtain the present CGI value.

It is not required to manipulate the currGameIndex variable directly, which actually holds a 0-based index value while CGI data as exposed on the Game Generator interface as well as CGI getters and setters are 1-based. Also, modifying the currGameIndex variable directly will not provide a correct feedback to the Game Generator interface.

Also, you can use the showLogGrid(gameIndexValue) function to view the raw grid / tile data of a game instance in the console. Provide the 1-based game instance index value (as agreeing with CGI values) as the value of the gameIndexValue parameter.

Features planned, not yet implemented:

• Improved features on the Game Generator interface.
• AI Solver
• Single-Input Multiple-Reflection difficulty mode.
• Other game enhancements.
