Syntax

class UPCGActorAndComponentMapping

Remarks

This class handle any necessary mapping between actors and pcg components. Its meant to be part of the PCG Subsystem and owned by it. We offload some logic to this class to avoid to clutter the subsystem. For now it is used for:

  • Mapping between PCG Components and Partition actors: Dispatch tasks from original components to local components
  • Tracking non partitioned PCG Components that has tracking actors needs.
  • Tracking actors: Be able to react to actors changes, and potentially dirty/refresh affected components

Functions

  Type Name Description
Public function void  
Public function Const TSet< UPCGComponent * > Return a copy of all the registered components. Thread safe
Public function Const TSet< UPCGComponent * > Return a copy of all the registered non-partitioned components. Thread safe
Public function Const TSet< UPCGComponent * > Return a copy of all the registered partitioned components. Thread safe
Public function bool

RegisterOrUpdatePCGComponent ( UPCGComponent* InComponent,
bool bDoActorMapping
)

 Register a new PCG Component or update it. Returns true if it was added/updated. Thread safe
Public function void

RegisterOrUpdateTracking ( UPCGComponent* InComponent,
bool bInShouldDirtyActors
)

 Will register/update tracking if a component was registered/updated.
Public function void

RegisterPartitionActor ( APCGPartitionActor* InActor,
bool bDoComponentMapping
)

 Register a new Partition actor, will be added to a map and will query all intersecting volume to bind to them if asked.
Public function void  
Public function bool

RemapPCGComponent ( const UPCGComponent* OldComponent,
UPCGComponent* NewComponent,
bool bDoActorMapping
)

 In case of BP Actors, we need to remap the old component destroyed by the construction script to the new one.
Public function void If the partition grid size change, call this to empty the Partition actors map
Public function void  
Public function void

Tick ()

 Should be called by the subsystem to handle delayed operations.
Public function void

UnregisterPartitionActor ( APCGPartitionActor* InActor
)

 Unregister a Partition actor, will be removed from the map and remove itself to all intersecting volumes.
Public function void

UnregisterPCGComponent ( UPCGComponent* InComponent,
bool bForce
)

 Unregister a PCG Component. Can force it, if we have a delayed unregister. Thread safe
