Create your own Spline Components:
The class SplineModifierWithCallbacks is a MonoBehavior class. It receives callbacks whenever there is a change in the Spline.
All you need to do in order to start your own Spline Modifier.is inherit from this class.
It contains 2 callbacks:
Use ImmediateCallback() to set values
and use OnUpdateCallback() when you need to change the scene hierarchy, like adding or deleting gameObjects.
The class grants public access to the spline data:
- point positions
- length of spline
- length of each segment
- position in the spline at a given t
- position in the spline at a given length
- and many other settings and calculations useful for any purpose.
Every component in this tool inherits from this class and can also access the information publicly.
