Stores the setup pose for a transform constraint. See [url]http://esotericsoftware.com/spine-transform-constraints[/url] in the Spine User Guide. The bones that will be modified by this transform constraint. Modifying the array has no effect. 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 scale X. A percentage (0-1) that controls the mix between the constrained and unconstrained scale Y. A percentage (0-1) that controls the mix between the constrained and unconstrained shear Y. 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. An offset added to the constrained bone rotation. An offset added to the constrained bone scaleX. An offset added to the constrained bone scaleY. An offset added to the constrained bone shearY. An offset added to the constrained bone X translation. An offset added to the constrained bone Y translation. The target bone whose world transform will be copied to the constrained bones.
