Hi, welcome to the forum!

There is a script in this thread that implements the Catmull-Rom spline. How you plot the points depends on what you need to do in the game. Are you drawing the curve in space, on a flat surface, terrain… ? As for the rigidbody, it is not all that straightforward to make it follow a spline path (there’s no spline joint or anything similar). Can you give any more information about what the rigidbody is doing in gameplay?

I’m drawing shapes using LineRenderer.

Declared: private LineRenderer line;

Then in Awake, line = gameObject.AddComponent();
It gives me a complete shape when i connect the start and end. At this point, i want this shape to become rigidbody and gravity and collision applicable to it.

How to achieve this?
