Trait keeshond::scene::ThinkerSystem

pub trait ThinkerSystem<T: SceneType + 'static> {
    fn think(&mut self, args: ThinkerArgs<'_, T>);

    fn start(&mut self, args: ThinkerArgs<'_, T>) { ... }
    fn start_late(&mut self, args: ThinkerArgs<'_, T>) { ... }
    fn end(&mut self, args: ThinkerArgs<'_, T>) { ... }
    fn priority(&self) -> i32 { ... }
}

A system that runs game logic every frame, typically giving Entities behaviors based on which Components they have.

Required Methods

fn think(&mut self, args: ThinkerArgs<'_, T>)

Called once every logic frame. This is where you do your main processing.

Provided Methods

fn start(&mut self, args: ThinkerArgs<'_, T>)

Called before the first frame of logic processing. You can use this to spawn in objects and do any other necessary setup.

fn start_late(&mut self, args: ThinkerArgs<'_, T>)

Called after ThinkerSystem::start() but before the first frame of logic processing. This is useful if you need to do initialization tasks after any deferred actions such as object spawning.

fn end(&mut self, args: ThinkerArgs<'_, T>)

Called when the scene is ending, such as when the gameloop is switching to a new scene. This is a good place to do resource cleanup, save settings and persistent data, or other tasks.

fn priority(&self) -> i32

Used to determine the order of execution of each ThinkerSystem. Lower number priority systems are executed first.
