Stores the current pose for a physics constraint that applies physics to bones. A physics constraint applies physics simulation to bones, allowing them to move and react based on physical forces like gravity, inertia, and momentum. See [url=https://esotericsoftware.com/spine-physics-constraints]Physics constraints[/url] in the Spine User Guide. Updates the physics constraint. The physics parameter determines how physics are applied. See [enum SpineConstant.Physics]. Returns the data for this physics constraint. Returns the bone constrained by this physics constraint. Sets the bone constrained by this physics constraint. Returns the current pose for this physics constraint. Returns the applied pose for this physics constraint. Resets the physics constraint. Translates the physics constraint so next update forces are applied as if the bone moved an additional amount in world space. Rotates the physics constraint so next update forces are applied as if the bone rotated around the specified point in world space.
