Tet.rs - Guideline-ish Tetris clone written in Rust

• Super Rotation System implemented (e.g. supports the same wallkicks as a modern Tetris game)
• Bag randomizer
• Ghost piece

Differences from Guideline

• Holding a direction key snaps a piece to the corresponding edge of the screen after a configurable delay, e.g. ARR = 0
• No scoring/timing. Won't add the former, may add the latter one day
• Pieces never lock on their own, you have to manually hard drop them
• Only one piece preview to simplify graphics, may change later
• No gravity, probably won't add this
• Soft drop is instantaneous, will change if and only if the above changes
• Default controls are my preferred controls (up for hard drop, z/x for rotation, shift for hold)

Installation

Non-Nix(OS)

• Ensure GNU make, cmake, and the SDL2 library are installed
• Use cargo install --path .
• Only tested on Linux but probably works for other platforms?

Nix(OS) with flakes

• Provides a flake.nix adapted from my rust flake template
• tetrs.overlays.default is an overlay that adds tetrs to pkgs
• tetrs.nixosModules.default is a Home Manager module for configuring tetrs, only needed if you want to change the default settings (under ./config/default.toml)
• Also provides a dev shell, enter root directory and run nix shell
• Or, if using direnv run the below commands from root directory:
  • echo "use flake" >> .envrc
  • direnv allow
• To run locally just use cargo run inside the shell environment, or use nix flake run

Configuration

• Configuration file is optional and located at ~/.config/tetrs/config.toml
• Supports configuration of all keybindings, as well as DAS, the length of time (in ms) you have to hold a direction key for the piece to snap to the edge of the screen. Default 150
• Default configuration is under ./config/default.toml and should hopefully be self-explanatory.
