Syntax

class FPhysicsDataCollection

Remarks

FPhysicsDataCollection holds onto physics-system data that is needed for various interactive tools and algorithms. Currently this is split into two parts, pointers to the owning physics state, and collision geometry data.

The collision geometry data is stored in both the editable GeometryProcessing format and the physics-system representations (currently FKAggregateGeom but more are expected). This class provides a high-level API for transferring geometry between these two representations.

Variables

	Name	Description
FKAggregateGeom	AggGeom	Collision geometry in Physics-system format. Not necessarily in sync with Geometry member.
TWeakObjectPtr<...	BodySetup	The BodySetup in use by the SourceComponent
FVector	ExternalScale3D	Scaling factor applied to the SourceComponent, which should be transferred to Collision Geometry in some cases
UE::Geometry::F...	Geometry	Geometry data Stores representation of Collision geometry
TWeakObjectPtr<...	SourceComponent	External State DataThe Component this physics data came from / is for
TWeakObjectPtr<...	SourceStaticMesh	The StaticMesh this physics data came from / is for
