Raycasting not behaving as expected?

Question

In my 2d game the world is laid out in blocks (Like 2d minecraft) and I am trying to make the player break the block below him when he hits the mine button. Here is my code:

 if(Input.GetButtonDown("MineDown"))
         {
             
             Transform other = Physics2D.Raycast(new Vector2(gameObject.transform.position.x, gameObject.transform.position.y), new Vector2(Vector3.down.x, Vector3.down.y), Mathf.Infinity).transform;
             Destroy(other.gameObject);
         }

The only problem is when I press the mine button, the player gets destroyed and not the block below it. This is not the behavior I expected, but I don't know how to fix it.

Add a layer mask to your Raycast() so that it hits only the blocks layer and ignores the player. It most likely hits the player first. http://docs.unity3d.com/ScriptReference/Physics2D.Raycast.html

The ray is hitting your player most likely. Add a LayerMask for the blocks and Raycast() only on that layer.
