Syntax

struct FConstraintProfileProperties

Remarks

Container for properties of a physics constraint that can be easily swapped at runtime. This is useful for switching different setups when going from ragdoll to standup for example

Variables

	Name	Description
float	AngularBreakThreshold	Torque needed to break the joint.
FAngularDriveCo...	AngularDrive
uint8: 1	bAngularBreakable	Whether it is possible to break the joint with angular force.
uint8: 1	bDisableCollision	Disable collision between bodies joined by this constraint.
uint8: 1	bEnableProjection	If distance error between bodies exceeds 0.1 units, or rotation error exceeds 10 degrees, body will be projected to fix this.
uint8: 1	bLinearBreakable	Whether it is possible to break the joint with linear force.
uint8: 1	bParentDominates	When set, the parent body in a constraint will not be affected by the motion of the child.
FConeConstraint	ConeLimit
float	LinearBreakThreshold	Force needed to break the distance constraint.
FLinearDriveCon...	LinearDrive
FLinearConstrai...	LinearLimit
float	ProjectionAngularTolerance	Angular tolerance value in world units.
float	ProjectionLinearTolerance	Linear tolerance value in world units.
FTwistConstrain...	TwistLimit
