Resolved [Splines] How to move a knot from code (effectively)?

I want move first knot of a spline to target transforms position. This code works nicely:

Edit : this works only if target transform child of spline object, see my other post for real solution.

Code (CSharp):

1. var firstKnot = MySpline.Spline.ToArray()[0];
2. firstKnot.Position = TargetTransform.position;
3. MySpline.Spline.SetKnot(0,firstKnot);

But seems too much for just a float3 change. Is there way to handle like this ?

Code (CSharp):

1. MySpline.Spline.Knots[0].position = TargetTransform.position;

I looked documentation but maybe I missed something.

 

I have the same problem.
Does anyone know?

 

If you want to move a spline to the target world position and rotation,

Code (CSharp):

1.   public SplineContainer MySpline;
2.     public Transform KnotTarget;
3.  
4.     private void Update()
5.     {
6.         var firstKnot = MySpline.Spline.ToArray()[0];
7.  
8.         firstKnot.Position = MySpline.transform.InverseTransformPoint(KnotTarget.position);
9.         firstKnot.Rotation = Quaternion.Inverse(MySpline.transform.rotation) * KnotTarget.rotation;
10.  
11.         MySpline.Spline.SetKnot(0,firstKnot);
12.  
13.     }

with that first knot always copy target transform world position and rotation even spline itself move or rotate.
Just like a Parent constraint component.
