Find (Get) linerenderer vertex positions

Questions & Answers
1

How can find the value of linerenderer vertex position?
There is a SetPosition() function to edit a value,
but no GetPosition()function that just returns the current value.

I want to make an existing line longer:
a cable lowering an object.
The cable has a start distance set in the inspector.

Create a List; and add there your positions, after you can acess it like an array:

using System.Collections.Generic;

...

public List<Vector3> lineRendererVertexes;

....

lineRendererVertexes = new List<Vector3>();

....

lineRendererVertexes.Add(newPosition);

....

for( int i = 0; i < lineRendererVertexes.Count; i++)
{
     lineRendererVertexes *....*

}

Created a variable that i manually set to hold the same value as the value in the inspector.
And add the movement distance to that value to find the final value I need.
