SplineController Reset to initial Position

[aspartamed]

I am using the Spline Controller to move an object along a single spline.

Sometimes I need to "reset" the object to the start of the spline. How do I do that?

I tried calling 
mysplineController.Stop();
mysplineController.Play(); 

but that didn't seem to work so then I did

mysplineController.ResetOnStop = true;
mysplineController.Stop();
mysplineController.Play();

But that causes an exception below.

I also tried mysplineController.Warp(0); 

What is the best way to reset the object to the start of the spline?



Thanks
Jim

Either use 

mySplineController.Reset()  

or 

mySplineController.Position=mySplineController.InitialPosition

Both should work. I'm looking into the exception, that shouldn't happen. Anyways, ResetOnStop only has an effect if you use the Animate feature.

Thanks for the fast response 

mySplineController.Reset()   is protected.

Something to note is I am dynamically changing the location of the ControlPoints of the Spline used by the SplineController. So its possible that is part of the cause of the index out of bounds, I suspect the spline is getting shorter and that isnt handled by that code.

Is there something that should be called when the spline is changed?

Either use 

mySplineController.Reset()  

or 

mySplineController.Position=mySplineController.InitialPosition

Both should work. I'm looking into the exception, that shouldn't happen. Anyways, ResetOnStop only has an effect if you use the Animate feature.

Yeah, call CurvySpline.Refresh() to immediately use the changes, otherwise Refresh() will be called internally next frame. In general, calling Refresh() often isn't bad - it won't do anything unless spline parts are flagged dirty or you force refresh by Refresh(true).
