INFO1113 Assignment 1 - 2048

Due: 13 April 2025, 11:59PM AEST

This assignment is worth 8% of your final grade.

Task Description

Implement the 2048 game using the Processing library for graphics and Gradle as a dependency manager.

Setup of Gradle and a demonstration of the graphics capability of Processing will be done in the week 5

tutorial. You can access the documentation from here. As with any assignment, make sure that your work

is your own, and do not share your code or solutions with other students.

The game takes place on an

×

grid, initially with 2

randomly placed blocks (which are randomly selected from

either a 2 or 4 with equal chance). The parameter n should be

retrieved from command line arguments. If it is invalid or not

provided, use the default which is n=4.

Each turn, the player may make one of four moves with the

arrow keys: UP, DOWN, LEFT or RIGHT. This shifts all blocks in

that given direction, and also merges adjacent blocks with the

same number into a higher value (eg, 4 and 4 makes 8). You

should ensure that block movement is smoothly transitioning

from one cell to the next (as in the example game linked

above), OR that only one block moves one space per frame.

After the player’s move is finished, a new random block will

spawn in one of the empty spaces. This can be either a 2 or a

4. In addition, the player may also spawn any amount of new

blocks into empty cells themselves by clicking on an empty

space, and a 2 or 4 will then spawn there (randomly chosen

with 50% chance). If the player is unable to make any moves

that change the position of blocks, the game is over.

A timer in the top right corner of the screen should keep track

of the number of seconds since the game began. When the

game ends, this timer stops, and the text “GAME OVER” is

displayed in the centre of the screen. The player can press ‘r’ to

restart the game.

value higher than 2048 uses the same colour

Marking Criteria (8%)

Your final submission is due on Sunday 13 April 2025 at 11:59PM. To submit, you must upload your

build.gradle file and src folder to Ed. Do NOT submit the build folder. Ensure src is in the root directory

with the other files, and not part of a zip, then press MARK.

Shown during tutorial in week 5

when Gradle and Processing are

covered.

(-1 deduction if your submission

breaks these features)

• Window launches and shows initial layout correctly with brown cells.

• Hovering over tiles with cursor changes the brown tile to a lighter

colour to highlight it

• Left clicking on a cell places a ‘2’ or a ‘4’ randomly in that position

1 mark • Board size adjusts based on command line argument input (default

4x4 if not provided)

• Timer counts up every second in the top-right corner of the screen. It

stops when the game ends.

0.5 marks • Tile colours are correctly shown to differentiate different values

1.5 marks • Arrow keys result in tile movement in the corresponding direction

(LEFT, RIGHT, UP, DOWN) if there is empty space for the tiles to move

– 0.5 mark deduction for each with bugs or not working

1.5 marks • Adjacent tiles are merged correctly after the player makes a move in

either LEFT, RIGHT, UP or DOWN directions – 0.5 deduction for each

not working

1 mark • Random block spawns in an empty cell after the player’s move –

either a 2 or a 4

1 mark • If the player is unable to make any moves that change the position of

blocks, the game is over. Display “GAME OVER”. Player can press ‘r’ to

restart the game.

1.5 mark • Movement is progressive such that blocks smoothly transition from

one cell to the next (such as in https://play2048.co/) OR only one

block can move one space on each frame.
