Spline Scrubber is a Unity plugin that integrates Unity Spline package with the Unity Timeline to choreograph spline-driven animations. It offers custom timeline tracks, enabling precise animation sequencing along splines.
By leveraging the performance benefits of the C# job system and burst compiler, the plugin efficiently evaluates splines and updates transforms in a multithreaded manner, at runtime and during edit mode.

To choreograph spline-driven animations with Spline Scrubber:
SplineCart: Attach this to the game objects you wish to animate. It serves as the track binding for the SplineTrack.SplineTrack: For each object, add this custom timeline track to your timeline assets.SplineClip: Use this custom timeline clip within the SplineTrack to dictate the object's movement along the spline for the clip's duration.SplineJobController: For every Spline(Container), include this component to pre-process and cache spline data, optimizing job execution.SplineJobsScheduler: Ensure one instance of this singleton exists in your scene. It manages the real-time evaluation of splines and updates object transforms each frame.
