Implementations

impl<'a> Engine<'a>

pub fn new(
    app: &'a mut dyn Application,
    title: &'a str,
    width: u32,
    height: u32
) -> Result<Engine<'a>, String>

Create a new engine.

Parameters

• app: Defines the application’s logic.
• title: Title of the window.
• width: Width (in pixels) of the window.
• height: Height (in pixels) of the window.

Example

use simple_game_engine::Engine;
let mut app = App {}; // Some `Application` implementation
let engine = Engine::new(&mut app, "Window Title", 640, 480)?;

pub fn start(&mut self, present_vsync: bool) -> Result<(), Box<dyn Error>>

Create and show the window and start the main event loop.

Parameters

• present_vsync: Whether to limit the frame rate of the application to the frame rate of the display.

Example

use simple_game_engine::Engine;
let mut app = App {}; // Some `Application` implementation
let mut engine = Engine::new(&mut app, "Window Title", 640, 480)?;
engine.start(true)?; // Starts with vsync enabled
