OnMouseOver() right click cursor - not triggering the code

Question

Hello.

I am trying to make a simple physics game and throw some gameObjects. I want to pick up a box with mouse cursor and throw it. I googled, and found a piece of code which works technically, but only with OnMouseDown() it is left click. But I want right click :D!

Problem with the script: It is not registering right click at all, I probably messed up. I'm just a beginner (3th day).

This is what I have for now:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class DragObj : MonoBehaviour
 {
     private Vector3 screenPoint;
     private Vector3 offset;
 
 
     void OnMouseOver()
     {
         if (Input.GetMouseButtonDown(1))
         {
             screenPoint = Camera.main.WorldToScreenPoint(gameObject.transform.position);
             offset = gameObject.transform.position - Camera.main.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z));
         }
     }
 
     void OnMouseDrag()
     {
         if (Input.GetMouseButtonDown(1))
         {
             Vector3 cursorPoint = new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z);
             Vector3 cursorPosition = Camera.main.ScreenToWorldPoint(cursorPoint) + offset;
             transform.position = cursorPosition;
         }
     }
 }

@priit1989 I have created a decent example script for you to further expand and it has comments to explain what is going on. So I hope it helps.

     [Header("Needed to get the mouse position of the player")]
     public Camera cam;
 
     [Header("How far a player can hit an object from")]
     public float reachOfPlayer = 15;
 
     [Header("Player's throw force of objects | PS: THE OBJECT BEING THROWN MUST HAVE RIGIDBODY COMPONENT TO WORK")]
     public float throwForce = 15;
 
     [Header("This will display our currently selected object")]
     public GameObject selectedObject = null;
 
     [Header("Offset of x, y, and z from the player")]
     public Vector3 offset = new Vector3(1, 1, 1);
 
     [Header("Speed our selected object moves towards our grabbed position")]
     public float speed = 30;
 
     //Variables:
     private bool clicked = false;
     private bool holding = false;
 
     private Transform selectedObjectsParent;
 
     private void Update()
     {
         //If left clicked
         if (Input.GetMouseButtonDown(1))
         {
             //Perform our click function
             ClickedOnObject();
 
             //If we are holding the object and it is not null and it has been clicked
             if (holding && selectedObject != null && clicked)
             {
                 //We are throwing the object so set the parent back to its original parent
                 selectedObject.transform.parent = selectedObjectsParent;
 
                 //Let our object rotate all it wants now
                 selectedObject.GetComponent<Rigidbody>().freezeRotation = false;
 
                 //Make sure our object can move freely now
                 selectedObject.GetComponent<Rigidbody>().constraints = RigidbodyConstraints.None;
 
                 //Get its rigidbody and throw it in a forward direction from our player with our players throw force
                 selectedObject.GetComponent<Rigidbody>().AddRelativeForce(transform.forward * throwForce, ForceMode.Impulse);
 
                 //We are no longer selecting the object so set it to null
                 selectedObject = null;
 
                 //We are not holding our object so set holding to false
                 holding = false;
 
                 //Our object is no longer selected so set clicked to false
                 clicked = false;
             }
         }
 
         //If we are currently selecting an object and we clicked it
         if (selectedObject != null && clicked)
         {
             //If our object is not throwable then we can not grab it
             if (selectedObject.GetComponent<Rigidbody>() == null)
             {
                 //We are no longer selecting the object so set it to null

                 clicked = false;
 
                 return;
             }
             //Lets parent the selected object we our holding to our player so it follows our rotation
             selectedObject.transform.parent = transform;
 
             //Make sure our object does not rotate around
             selectedObject.GetComponent<Rigidbody>().freezeRotation = true;
 
             //Make sure our object stays held in the air
             selectedObject.GetComponent<Rigidbody>().constraints = RigidbodyConstraints.FreezePositionY;
 
             //Set our selected object to follow our players position with a set offset
             Vector3 newObjectPosition = new Vector3(transform.position.x + offset.x, transform.position.y + offset.y, transform.position.z + offset.z);
             selectedObject.transform.position = Vector3.MoveTowards(selectedObject.transform.position, newObjectPosition, speed * Time.deltaTime);
 
             //Now we know we are for sure holding the selected object so set holding to true
             holding = true;
         }
     }
 
     void ClickedOnObject()
     {
         //Will hold the reference for the clicked object
         RaycastHit hit;
 
         //Find the position and direction from the mouse
         Ray ray = cam.ScreenPointToRay(Input.mousePosition);
 
         //Using the direction and origin from the mouse(ray)
         //Output the hit object (out hit)
         //Max Distance the ray can go until it hits an object(reachOfPlayer)
         if (Physics.Raycast(ray, out hit, reachOfPlayer))
         {
             //If the hit object has not been clicked
             if (clicked == false)
             {
                 //Set our selected object
                 selectedObject = hit.transform.gameObject;
 
                 //Save our selected objects original parent
                 selectedObjectsParent = selectedObject.transform.parent;
 
                 //Make sure we set our object as clicked
                 clicked = true;
             }
         }
     }
