fn draw(&mut self, _: &mut Framebuffer<'_>)
source§fn fixed_update(&mut self, delta_time: f64)
fn fixed_update(&mut self, delta_time: f64)
Called periodically every
fixed_delta_time
defined in [ContextOptions].
To start the application with different fixed_delta_time
,
initialize geng with [Geng::new_with()
].source§fn handle_event(&mut self, event: Event)
fn handle_event(&mut self, event: Event)
Called whenever an event is registered. See Event for a full list of possible events.
source§fn transition(&mut self) -> Option<Transition>
fn transition(&mut self) -> Option<Transition>
Called every frame. If returns
Some
, then a transition occurs.fn ui<'a>(&'a mut self, cx: &'a Controller) -> Box<dyn Widget + 'a>
