RaycastAll for 2D

I am trying to do a RaycastAll for 2D and collide with all sprites that are positioned on top of each other. I have a bit of a problem to get this to work properly and do not fully understand how to put a direction in the 2D-space in this scenario.

I would like to ask for some help how the full statement will look like?

Here is the syntax:

Code (csharp):

1. static RaycastHit2D[] RaycastAll(Vector2 origin, Vector2 direction, float distance = Mathf.Infinity, int layerMask = DefaultRaycastLayers, float minDepth = -Mathf.Infinity, float maxDepth = Mathf.Infinity);

Here is the code i use to select a single sprite:

Code (csharp):

1. RaycastHit2D hit = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(Input.mousePosition), Vector2.zero);

Here is the code i testing:

Code (csharp):

1. RaycastHit2D[] hits = Physics2D.RaycastAll(hit.transform.position,-hit.transform.up,0.6f);

 

Hmmm as soon as I posted this I was able to solve it, should have tested a bit more. Here is the code i use for the test:

Code (csharp):

1. RaycastHit2D hit = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(Input.mousePosition), Vector2.zero);
2.  
3.             RaycastHit2D[] hits = Physics2D.RaycastAll(hit.transform.position,-hit.transform.up,0.6f);
4.  
5.             print ("xx: " + hits.Length);
6.  
7.             for(int x = 0; x < hits.Length; x++) {
8.                 print ("S: " + hits[x].transform.tag);
9.             }
