Syntax

public abstract class TrackingSubsystem<TTrackable, TSubsystem, TSubsystemDescriptor, TProvider> : SubsystemWithProvider<TSubsystem, TSubsystemDescriptor, TProvider>, ISubsystem where TTrackable : struct, ITrackable where TSubsystem : SubsystemWithProvider, new() where TSubsystemDescriptor : SubsystemDescriptorWithProvider where TProvider : SubsystemProvider<TSubsystem>

Type Parameters

Name	Description
TTrackable	The trackable's data, often a blittable type to inter-operate with native code.
TSubsystem	Concrete subsystem deriving from TrackingSubsystem.
TSubsystemDescriptor	The subsystem descriptor for the underlying subsystem.
TProvider	Provider type for the TrackingSubsystem-derived subsystem.

Methods

GetChanges(Allocator)

Retrieves a set of changes (additions, updates, and removals) since the last time GetChanges(Allocator) was called. This is typically called once per frame to update the derived class's internal state.

Declaration

public abstract TrackableChanges<TTrackable> GetChanges(Allocator allocator)

Parameters

Type	Name	Description
Allocator	allocator	The Allocator to use when creating the NativeArrays in TrackableChanges<T>.

Returns

Type	Description
TrackableChanges<TTrackable>	The set of changes since the last time this method was invoked.
