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
float	AngularPlasticityThreshold	Degree threshold from target angle needed to reset the target angle.
uint8: 1	bAngularBreakable	Whether it is possible to break the joint with angular force.
