Raycast for a 2D objects

I'm sorry to post this because I have seen others with similar posts but the reason I'm still posting it is because I'm struggling to translate it. Here's my code on a 2D object even though it's meant for a 3D and that's why I'm here.

 if (Input.GetMouseButton (0)) {
             Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
             RaycastHit hit ;
             if(Physics.Raycast(ray, out hit) && hit.collider.gameObject.name =="MoveJump"){
 
                 Move.Jump ();}

Okay... Whnat do yu mean by "2D object even though it's meant for a 3D"?

Be aware that there exists a Raycast2D function for raycasting against 2D objects (those with 2d colliders).

 Ray2D ray = Camera.main.ScreenPointToRay (Input.mousePosition);
         RaycastHit2D hit;
         if(Physics2D.Raycast2D(ray, out hit) && hit.collider.gameObject.name == "$$anonymous$$oveRight"){
         $$anonymous$$ove.Right();

I'm experiencing the errors cannot convert ray to ray2d and physics2d does not contain a definition for raycast2d

There's no Physics2D.Raycast2D, it is Physics2D.Raycast. Also look at the proper way to use it in the scripting api as it is different from Physics.Raycast.

Really struggling to translate because I'm an absolute beginner and hate to ask so much from but could you help me out a little more because the code used in the example seems so complex and foreign.
