Navni is intended as a display library for both text graphics and pixel art games. It can be built for either a native TTY console or for a desktop GUI window, and text graphics will use the native TTY display on TTY.
You need to pick the backend using feature flags when using Navni, either
--features=tty for TTY or --features=gui for the GUI desktop backend. To
test the examples, run
cargo run --features=tty --example demo
or
cargo run --features=gui --example demo
Navni takes responsibility for the "magical" platform-specific I/O interfaces involved in making a game, and only for those. It will not provide any game development functionality that's purely computational, such as pathfinding, procedural generation or sprite sheet management.
- Async execution model for the game loop allows writing complex user interface control flow without having to make everything into an explicit state machine.
- Simple mouse and keyboard event handling.
- Logging backend activator, use syslog logging with TTY builds where you can't output extra lines to stdout and a stdout-based logger with Linux GUI builds.
- GUI builds can target WASM using miniquad's JavaScript webgl shim.
- File system abstraction that provides machinery for saving and loading config and data files that works both on desktop via the host file system and in browser WASM builds via HTML Web Storage.
