Tetris Game using Python3

Problem description

The engine models a grid that pieces enter from top and come to rest at the bottom, as if pulled down by gravity. Each piece is made up of four unit squares. No two unit squares occupy the same space in the grid at the same time. The pieces are rigid, and come to rest as soon as any part of a piece contacts the bottom of the grid or any resting block. As in Tetris, whenever an entire row of the grid is filled, it disappears, and any higher rows drop into the vacated space without any change to the internal pattern of blocks in any row. The exe file process a text of lines each representing a sequence of pieces entering the grid. For each line of the input programs output the resulting height of the remaining blocks within the grid. The file denotes the different possible shapes by letter. The letters used are Q, Z, S, T, I, L, and J. The shapes of the pieces they represent are shown in the table below:

Letter	Q	Z	S	T	I	L	J
Shape	## ##	## ##	## ##	### #	####	# # ##	# # ##

The program does not validate its input for now and assumes that there will be no illegal characters Moreover, the script does not account for shape rotation in your model. The pieces will always have the orientations shown above. Each line of the input file is a comma-separated list. Each entry in the list is a single letter (from the set above) and a single-digit integer. The integer represents the left-most column of the grid that the shape occupies, starting from zero. The grid of the game space is 10 units wide. For each line of the file, the grid’s initial state is empty.

For example, if the input file consisted of the line “Q0” the corresponding line in the output file would be “2”, since the block will drop to the bottom of the initially empty grid and has height two.

Examples

Example 1

A line in the input file contains I0,I4,Q8 resulting in the following configuration:

  I0 │          │ I4  │          │ Q8  │          │
     │          │ ──► │          │ ──► │        ##│
     │####      │     │########  │     │##########│
     └──────────┘     └──────────┘     └──────────┘
      0123456789       0123456789       0123456789

The filled bottom row then disappears:

│          │
│          │
│        ##│
└──────────┘
 0123456789

Therefore, the output row for this sequence is “1”.

Example 2

A line in the input file contains T1,Z3,I4.

     │          │       │          │       │    ####  │
  T1 │          │  Z3   │   ##     │  I4   │   ##     │
     │ ###      │  ──►  │ #####    │  ──►  │ #####    │
     │  #       │       │  #       │       │  #       │
     └──────────┘       └──────────┘       └──────────┘
      0123456789         0123456789         0123456789

No rows are filled, so the output for this sequence is “4”.

To run the Tetris game, follow these steps:

1. Navigate to the project directory:

   cd tetris-game

2. Make the tetris script executable:

   chmod +x tetris.py

Usage

Run the Tetris game with the following command:

Gameplay

Additional information about how to play the game or special features.

Starting the Game

To play the Tetris game, follow these steps:

1. Open a terminal window.

2. Navigate to the project directory:

   cd path/to/encord-be-assignment

3. To start the game with default settings, type in terminal:

   ./tetris <input.txt>
   

Ending the Game

The game will end if any key is pressed, except for the required input format. Ensure that your input follows the specified format (e.g., Q2, S2) to continue playing. The final score will be displayed, and the game will exit.

Running Test Cases

You can test the Tetris game with predefined input scenarios. Follow these steps:

Ensure that the game is working correctly by running the provided test cases:

python3 sample_test.py

Please note that the subprocess.run command in sample_test.py may need modification.

1. Replace this line in sample_test.py:

   p = subprocess.run(
           ["/bin/bash", ENTRY_POINT],
           input=test_case.sample_input,
           capture_output=True,
       )

   With this line:

   p = subprocess.run(
           [ENTRY_POINT],
           input=test_case.sample_input,
           capture_output=True,
       )

2. Replace ENTRY_POINT in sample_test.py with ./tetris.py.
