procedure ClearItems; override;

Clears current scene

procedure HandleMessage(const Msg: TMessage); override;

procedure OnDestroy; override;

procedure ProcessDeltaTimeBased(const DeltaTime: TTimeUnit);

Performs delta time based items processing

procedure ProcessingEvent(EventID: Integer; const ErrorDelta: TTimeUnit);

Performs items processing

function QuerySubsystem(SubsystemClass: CSubsystem): TSubsystem;

Returns a registered subsystem of the specified class or successor

procedure RemovePass(const Item: BaseClasses.TItem); virtual; abstract;

For internal use only.

procedure RemoveSubsystem(const Subsystem: TSubsystem);

Unregister a subsystem

procedure SetProcessingClass(Index: Integer; Interval: Single; IgnorePause, DeltaTimeBased: Boolean);

Sets parameters of a processing class.
