RustPixel is a 2D game engine & rapid prototyping tools, supporting both text and graphics rendering modes.
It is suitable for creating 2D pixel-style games and developing terminal applications.
It can be compiled into FFI for front-end and back-end use, and into WASM for web projects.

• Text Mode: Built with crossterm, runs in the terminal, and uses ASCII & Unicode Emoji for drawing.
• Graphical Mode (SDL2 & WEB): Built with glow & sdl2, using PETSCII & custom graphics symbols for rendering.

Here is a petscii art painting browser made with rust_pixel. Special thanks to x.com/PETSCIIWORLD for the character painting and the transition shader provided by gltransition. Click here for online demo。

Features

• Game loops & Model/Render design pattern (game.rs)
• Event/Timer messaging mechanism (event.rs)
• Support text render mode (crossterm) (adapter.rs, cross.rs)
• Unified OpenGL drawing mode supports sdl and wasm (glow & sdl2) (adapter.rs, sdl.rs, web.rs)
• 3 core OpenGl shaders for sdl2 & web graphics mode: (gl/)
  • gl instance rendering shader for draw mainbuffer (render_symbols.rs)
  • gl transition shader for transition effect (render_transition.rs)
  • gl general 2d shader for draw render texture (render_general2d.rs)
• Some common game algorithms (algorithm.rs, algorithm/, util.rs, util/)
• audio & log support (audio.rs, log.rs)
• Demo games: tetris, tower, poker... (games/)
• Demo terminal ui app: palette... (apps/)
• Examples of wrapping core algorithms into FFI and WASM (games/poker/ffi, games/poker/wasm)

Installation Guide

The main steps of the installation process are as follows:

• Install DroidSansMono Nerd Font & setup terminal
• Install dependent libraries and softwares
• Install Rust and Wasm-pack

The detailed steps for each operating system:   MacOS   |   Linux   |   Windows

Starting from version 0.5.3, you can deploy cargo-pixel directly from crates.io:

cargo install rust_pixel         # use crates.io rust_pixel crate deploy cargo-pixel
cargo pixel                      # first run cargo-pixel will clone rust_pixel to <homedir>/rust_pixel_work automatic 
cd ~/rust_pixel_work             # cd to workspace
cargo pixel r petview s          # run demo game...

To use the newest code, you should clone RustPixel and deploy cargo-pixel tool:

git clone https://github.com/zipxing/rust_pixel
cd rust_pixel
cargo install --path . --force

If you have installed an old version of cargo-pixel, you may get an error when running it. git update is required and the new version of cargo-pixel is deployed manually:

cd rust_pixel
git pull
cargo install --path . --force

Usage Instructions

cd rust_pixel
cargo pixel run snake term            #Run the snake game in terminal mode
cargo pixel r snake t                 #Run the snake game in terminal mode - shorthand
cargo pixel r tetris s                #Run the Tetris game in SDL window mode
cargo pixel r tower w                 #Run tower in web,visit http://localhost:8080/ in your browser
cargo pixel r tower w --webport 8081  #Change web server port
cargo pixel r tower w -r              #Run with release mode

You can also use cargo pixel to create your own game or app:

cargo pixel c mygame           #Create mygame in ./apps using apps/template as a template

Creat a standalone app in some directory:

cargo pixel c myapp ..  #Create a standalone crate in ../myapp 
cd ../myapp 
cargo pixel r myapp t
cargo pixel r myapp s

RustPixel also includes several tools:

1. palette: A terminal-ui tool to generate, analyze, convert and manipulate colors.

cargo pixel r palette t -r

2. tedit: Used to edit character art assets, example:

#term mode
cargo pixel r pixel_edit term . assets/logo.txt

#graphics mode
cargo pixel r pixel_edit sdl . assets/logo.pix

3. tpetii: Used to convert regular images into PETSCII character art, example:

cargo pixel r pixel_petii t assets/a.png -r > assets/a.pix
cargo pixel r pixel_edit s . assets/a.pix

cargo pixel r pixel_petii t assets/lion.png 40 40 -r > assets/lion.pix
cargo pixel r pixel_edit s . assets/lion.pix

4. Script to automatically convert gif images into PETSCII animations (.ssf)

cargo pixel cg assets/sdq/fire.gif assets/sdq/fire.ssf 40 25
