bevy_terminal_display

A (very experimental) plugin for the Bevy engine which allows for rendering to a terminal window.

WARNING: I highly recommend using the kitty terminal emulator with this, not only due to the gpu-accelerated rendering, but also the implementation of the kitty protocol which enables the advanced input detection.

Features Include:

• TerminalDisplayBundle automatically sets up a correctly-formatted render texture
• Post-process dithers colors to pure black and white, which are then printed as braille characters to the terminal
• Responsiveness to terminal window resizing
• TerminalInput resource which keeps track of pressed & released keys
• Widget component for rendering ratatui TUI widgets
• TerminalWidget trait for creating custom TUI widget components
• Log redirection

Example Usage

In main.rs:

use bevy::prelude::*;
use bevy_terminal_display;

fn main() {
    App::new()
        .add_plugins((
            DefaultPlugins.build().disable::<WinitPlugin>().disable::<LogPlugin>,
            ScheduleRunnerPlugin::run_loop(Duration::from_secs_f32(1.0 / 60.0)),
            bevy_terminal_display::TerminalDisplayPlugin::default(),
        ))
        .insert_resource(Msaa::Off) // For post-process
        .run();
}

When spawning a camera:

let terminal_display_bundle = bevy_terminal_display::display::components::TerminalDisplayBundle::new(3, &asset_server);

commands.spawn((
    Camera3dBundle {
        camera: Camera {
            target: terminal_display_bundle.image_handle().into(),
            ..Default::default()
        },
        ..Default::default()
    },
    terminal_display_bundle,
));
