Features

• Sprites and styles with colors and attributes
  • Up to 24-bit color (depends on what the host terminal supports)
• Incremental drawing: Only draw on the screen when something has changed
• Transparency: Sprites can have holes so any sprites underneath will not be covered
• Position, show, and hide the cursor
• Set window title
• Plugs into Bevy's asset system so sprites and styles can be loaded from disk and also hot reloaded

pub fn main() { let mut settings = WindowSettings::default(); settings.set_title("Hello, World!");

App::build()
    // Add our window settings
    .add_resource(settings)
    // Add the DefaultPlugins before the CrosstermPlugin. The crossterm plugin needs bevy's asset server, and if it's
    // not available you'll trigger an assert
    .add_plugins(DefaultPlugins)
    .add_plugin(CrosstermPlugin)
