A slider constraint for animating properties. A slider constraint that can be used to animate various properties of bones. Sliders provide a way to control and animate bone transformations through constraint values. Updates the slider constraint. The physics parameter determines how physics are applied. See [enum SpineConstant.Physics]. Returns the data for this slider constraint. Returns the bone affected by this slider. Sets the bone affected by this slider. Returns the current pose for this slider. Returns the applied pose for this slider. Returns whether this slider is active. Sets whether this slider is active.
