BaseReactor

trait BaseReactor[A]

A reactor is a simple way to express an interactive program. It allows us to write programs in terms of some initial state and transformations of that state in response to inputs and clock ticks.

This is the basic interface. See Reactor for a more user friendly implementation.

It is based on * the same abstraction in Pyret.

Concrete methods

def run[Alg <: Basic, F[_], Frame, Canvas](frame: Frame)(implicit a: AnimationRenderer[Canvas], e: Renderer[Alg, Frame, Canvas], m: MouseClick[Canvas] & MouseMove[Canvas], runtime: IORuntime): Unit

Runs this reactor, drawing on the given frame, until stop indicates it should stop.

def tick[F[_], Frame, Canvas](frame: Frame)(implicit e: Renderer[Basic, Frame, Canvas], runtime: IORuntime): Option[A]

Run one tick of this reactor, drawing on the given frame. Returns the next state, or None if the Reactor has stopped.
