Syntax

[UCLASS](Programming/UnrealArchitecture/Reference/Classes#classdeclaration)(BlueprintType, Meta=(BlueprintSpawnableComponent))
class UNetworkPredictionPhysicsComponent : public UActorComponent

Remarks

UNetworkPredictionPhysicsComponent

This is a component that will register a FGenericPhysicsModelDef and bind to the first UPrimitiveComponent found in the parent actor. That is - there is NO backing NetworkPrediction simulation/gameplay code. This will always be SimulatedProxy and does not support any of the AP<>Server communication that UNetworkPredictionComponent.

To fully emphasize: this is for STAND ALONE physics objects that want to use NP's fixed tick services. It is NOT for "any NP object that uses physics". A vehicle that can be controlled by a client needs to use (or model after) UNetworkPredictionComponent.

Even then, it is just sort of an example. An extra component may not be the best way to use this. It may make more sense to just put the important bits on your actor class and set the exact UpdatedPrimitive you want (really PhysicsActorHandle is all that matters!)

Variables

	Name	Description
FNetworkPredict...	NetworkPredictionProxy	Proxy to interface with the NetworkPrediction system.
FReplicationPro...	ReplicationProxy
UPrimitiveCompo...	UpdatedPrimitive

Constructors

	Name	Description
	UNetworkPredictionPhysicsComponent()

Functions

	Name	Description
bool	CheckOwnerRoleChange()	Helper: Checks if the owner's role has changed and calls InitializeForNetworkRole if necessary.
FReplication...	GetReplicationProxies()
void	InitializeForNetworkRole ( ENetRole Role, const bool bHasNetConnection )	Finalizes initialization when NetworkRole changes. Does not need to be overridden.
void	InitializeNetworkPredictionProxy()	Classes must initialize the NetworkPredictionProxy (register with the NetworkPredictionSystem) here. EndPlay will unregister.
void	SetPrimitiveComponent ( UPrimitiveComponent* NewUpdate... )

Overridden from UActorComponent

	Name	Description
void	EndPlay ( const EEndPlayReason::Type EndPlayR... )	Ends gameplay for this component.
void	InitializeComponent()	Initializes the component.
void	PreReplication ( IRepChangedPropertyTracker& Change... )	Called on the component right before replication occurs

Overridden from UObject

		Name	Description
	void	PreNetReceive()	Called right before receiving a bunch
