Syntax

UCLASS (Transient)  
class UDynamicMeshReplacementChangeTarget :  
    public UObject ,  
    public IMeshReplacementCommandChangeTarget

Remarks

Bare bones wrapper of FDynamicMesh3 that supports MeshReplacementChange-based updates. Shares the mesh ptr with the MeshReplacementChange objects, so it must not be changed directly TODO: also support other MeshChange objects (by making a copy of the mesh when applying these changes)

Variables

	Type	Name	Description
	TSharedPtr< const FDynamicMesh3, ESPMode::ThreadSafe >	Mesh
	FSimpleMulticastDelegate	OnMeshChanged	This delegate fires when a FCommandChange is applied to this component, so that parent objects know the mesh has changed.

Constructors

	Type	Name	Description
		UDynamicMeshReplacementChangeTarget ()
		UDynamicMeshReplacementChangeTarget ( TSharedPtr< const FDynamicMesh3, ESPMode::ThreadSafe > Mesh )

Destructors

	Type	Name	Description
		~UDynamicMeshReplacementChangeTarget ()

Functions

Type	Name	Description
const TSharedPtr< const FDynamicMesh3, ESPMode::ThreadSafe > &	GetMesh ()
TUniquePtr< FMeshReplacementChange >	ReplaceMesh ( const TSharedPtr< const FDynamicMesh3, ESPMode::ThreadSafe >& UpdateMesh )	Update the mesh and return a corresponding FChange Does not emit the change.
void	SetMesh ( TSharedPtr< const FDynamicMesh3, ESPMode::ThreadSafe > MeshIn )

Overridden from IMeshReplacementCommandChangeTarget

	Type	Name	Description
	void	ApplyChange ( const FMeshReplacementChange* Change, bool bRevert )	Apply/Revert a general mesh change to the internal mesh (implements IMeshReplacementCommandChangeTarget)
