How to instantiate prefabs between 2 objects like a path

Hi, i am trying to make a level generator using prefabs. I want to generate a path of prefabs between 2 objects. However! These instantiated prefabs have fixed sizes, and need to connect with each other. Eventually the purpose is that the prefabs will be instantiated in a grid-like manner. And each time the path would be different. A L shape towards the end position. Or just a "curvy" path towards the end position.

Attached an example:

I am not asking for an script, merely a push in the right direction. I honestly don't know where to start.

This is the beginning of the "test" script what i came up with.

 var startNode : Transform;
 var endNode : Transform;
 var nodes : Transform;
 
  var startPosition : Vector3;
  var endPosition : Vector3;
 
 private var distance : float;
 private var center : Vector3;
 
 
 function Start()
 {
     startPosition = Vector3(0, 0, 0);
     endPosition = Vector3(startPosition.x + 5 * 5, 0,startPosition.z + 5 * 6);
     
     Instantiate(startNode, startPosition, Quaternion.identity);
     Instantiate(endNode, endPosition, Quaternion.identity);
     
     GeneratePath();
 }
 
 
 function GeneratePath()
 {
     
 }

So the startNode and endNode will be instantiated(eventually at a random location). And between them the generated "path". Of course the code that i have posted isn't much. But like i said, i just don't know where to start.

I really hope someone can help me!

Thanks in advance and cheers, Darryl
