Properties

AngularDampingScale

Type: float

Modifiers: const

Scaling factor to AngularDriveDamping in all RB_ConstraintInstances within this instance.

Default value: 1.0

AngularForceLimitScale

Type: float

Modifiers: const

Scaling factor to AngularDriveForceLimit in all RB_ConstraintInstances within this instance.

Default value: 1.0

AngularSpringScale

Type: float

Modifiers: const

Scaling factor to AngularDriveSpring in all RB_ConstraintInstances within this instance.

Default value: 1.0

Bodies

Type: array<RB_BodyInstance>

Modifiers: const, instanced

Array of RB_BodyInstance objects, storing per-instance state about about each body.

CollisionDisableTable

Type: Object.Map_Mirror{TMap<FRigidBodyIndexPair,UBOOL>}

Modifiers: const, native

Table indicating which pairs of bodies have collision disabled between them. Used internally.

Constraints

Type: array<RB_ConstraintInstance>

Modifiers: const, instanced

Array of RB_ConstraintInstance structs, storing per-instance state about each constraint.

LinearDampingScale

Type: float

Modifiers: const

Scaling factor to LinearDriveDamping in all RB_ConstraintInstances within this instance.

Default value: 1.0

LinearForceLimitScale

Type: float

Modifiers: const

Scaling factor to LinearDriveForceLimit in all RB_ConstraintInstances within this instance.

Default value: 1.0

LinearSpringScale

Type: float

Modifiers: const

Scaling factor to LinearDriveSpring in all RB_ConstraintInstances within this instance.

Default value: 1.0

Owner

Type: Actor

Modifiers: const, transient

Actor that owns this PhysicsAsset instance. Filled in by InitInstance, so we don't need to save it.

RootBodyIndex

Type: int

Modifiers: const, transient

Index of the 'Root Body', or top body in the asset heirarchy. Used by PHYS_RigidBody to get new location for Actor. Filled in by InitInstance, so we don't need to save it.

Native functions

FindBodyInstance

final native function RB_BodyInstance FindBodyInstance (name BodyName, PhysicsAsset InAsset)

Find instance of the body that matches the name supplied.

FindConstraintInstance
