Tetris - Rust

Preview

Instructions

Execute cargo build && cargo run to install the dependencies/build the program and then run it.

Execute cargo test to run the unit tests for this project.

The keybindings are UP, DOWN, LEFT, RIGHT, SPACE, Z, and X.

Requirements

You will need to install SDL2 mixer (for audio) and possibly SDL2: sudo apt-get install libsdl2-dev libsdl2-mixer-dev

Future Features to Consider

• All T-Spin setups
• All Z/S/L/J spin setups
• Combos (incremental sound effects)
• Hold a piece option
• Scores

  • Handles the random generation of the tetris pieces

Writeup

Developing this project required some experimenting with how to draw squares onto the screen using GlGraphics. I started off with a somewhat monolithic program file that had the bare minimum required to compile and run, which included the game loop and a simple square on the screen. The PistonTutorials link (referenced above) was really useful towards getting started. Before continuing, I planned to split the monolithic program into 5 different modules to keep the development process simple. From playing tetris for years, I drew a lot of diagrams on paper of how I understood the concepts to work, and translated the actual logic afterwards such as rotations for the different types of tetronimos. After getting all of the rotations done, the next step was to figure out the collisions between blocks and boundaries. Once the collisions, rotations, and placement problems were solved, fun features such as t-spin, sounds, and a randomizer (similar to the one used in TetrisFriends) were implemented. Overall, a lot of the development process involved experimenting, reading the documentation, and drawing the majority of the logic on paper before moving onto actual development.
