tetris

Tetris implementation in Python; I wrote this in an evening to test out Cursor.

Setup

Clone the repo, cd into it, then:

python3 -m venv ./venv
source venv/bin/activate
pip3 install -r requirements.txt

Gameplay

Start the game with python3 run.py (this will take a few seconds the first time you run it). Then:

• Left arrow / right arrow to control
• Up button to rotate
• Down to hard drop
• Space to pause
• ESC to quit

Design notes

Game loop

• setup
  • Start pygame
  • zero score
  • start music
• while running:
  • check if game is lost (squares exceed top row); quit if so
  • if no active tile:
    • perform rows check; eliminate any rows that are full and add to score
    • bump queued tile to active (draw it at top)
    • randomly get a new queued tile
  • get user input:
    • move tile left or right
    • rotate
    • pause
    • hard drop
  • attempt to move active tile down one square. If blocked, fill all occupied squares with boxes of same color and clear active tile.

Enhancements (once game MVP works)

• Actually display next piece
• Draw shadow
• level progressions with speedup
• Menu / multiple screens (options, high score, etc)
• Sound effects
• Score multipliers for clearing multiple rows
