EcsFrameLoop class final

Runs frame schedules and updates time.

Constructors

EcsFrameLoop(App app, {void onBeforeUpdate()?, void onCommandBoundary()?, void onFrameEnd()?})

Properties

app → App

The engine this loop drives.

final

hashCode → int

The hash code for this object.

no setter, inherited

onBeforeUpdate → void Function()?

Runs before the update schedule.

final

onCommandBoundary → void Function()?

Runs after each command flush.

final

onFrameEnd → void Function()?

Runs after render sync.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

ensureTimeResources() → void

Inserts default FrameTime/FixedTime/GameClock resources if a plugin has not already provided them. Call before App.start.

fixedStep(double fixedDt) → void

Runs one fixed step.

frameStart(Duration elapsed, double deltaSeconds) → double

Starts a frame and returns its scaled delta.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

update(double deltaSeconds) → void

Per-frame update: Schedules.postPhysics (the frame's fixed steps and physics integration have all run by the time the scene calls this), then onCommandBoundary, onBeforeUpdate, Schedules.update, onCommandBoundary again (where Game mounts nodes spawned during update), Schedules.renderSync, and finally onFrameEnd (e.g. flush scene-graph mutations) before render.

Operators

operator ==(Object other) → bool

The equality operator.
