    fn on_render(&mut self, _: &Context) -> Result<()> { ... }
    fn on_post_update(&mut self, _: &Context, _: &FrameInfo) -> Result<()> { ... }

}

Application is a user-friendly facade to building application, which defines a number of event functions that get executed in a pre-determined order.

Provided Methods

fn on_update(&mut self, _: &Context) -> Result<()>

Application::on_update is called every frame. Its the main workhorse function for frame updates.

fn on_render(&mut self, _: &Context) -> Result<()>

Application::on_render is called before we starts rendering the scene.

fn on_post_update(&mut self, _: &Context, _: &FrameInfo) -> Result<()>

Application::on_post_update is called after camera has rendered the scene.

fn on_receive_event(&mut self, _: &Context, _: ApplicationEvent) -> Result<()>

Application::on_update is called when receiving application event.

fn on_exit(&mut self, _: &Context) -> Result<()>

Application::on_exit is called when exiting.
