Stores the current pose for a path constraint. Stores the current pose for a path constraint. A path constraint adjusts the rotation, translation, and scale of the constrained bones so they follow a {@link PathAttachment}. See [url]http://esotericsoftware.com/spine-path-constraints[/url] in the Spine User Guide. The bones that will be modified by this path constraint. Modifying the array has no effect. The path constraint's setup pose data. A percentage (0-1) that controls the mix between the constrained and unconstrained rotation. A percentage (0-1) that controls the mix between the constrained and unconstrained translation X. A percentage (0-1) that controls the mix between the constrained and unconstrained translation Y. The position along the path. The spacing between bones. The slot whose path attachment will be used to constrained the bones.
