Stores a pose for a physics constraint. Stores the current pose values for a physics constraint, including physics properties like inertia, strength, damping, mass, wind, and gravity. Returns the inertia value for the physics constraint. Sets the inertia value for the physics constraint. Returns the strength value for the physics constraint. Sets the strength value for the physics constraint. Returns the damping value for the physics constraint. Sets the damping value for the physics constraint. Returns the inverse mass value for the physics constraint. Sets the inverse mass value for the physics constraint. Returns the wind value for the physics constraint. Sets the wind value for the physics constraint. Returns the gravity value for the physics constraint. Sets the gravity value for the physics constraint. Returns a percentage (0-1) that controls the mix between the constrained and unconstrained poses. Sets a percentage (0-1) that controls the mix between the constrained and unconstrained poses.
