Trying to instantiate a ball at the cursor position

Question

I've looked at various topics on this, and it seems that what I've got should work.

So I only want the ball to instantiate on the x axis of the mouse cursor. The other two axis are fixed. At the moment, no matter where I click, the ball spawns in the exact same position, even on the x axis, and below the camera. Hoping someone can tell me where I've gone wrong. Thanks.

 public class Ball : MonoBehaviour
 {
 
     [SerializeField] Camera mainCamera;
     [SerializeField] GameObject ball;
     Vector3 mousePosition;
 
     // Start is called before the first frame update
     void Start()
     {
         
     }
 
     // Update is called once per frame
     void Update()
     {    
         mousePosition = Input.mousePosition;
         mousePosition.y = 3.6f;
         mousePosition.z = 0f;
 
         var ballPos = mainCamera.ScreenToWorldPoint(mousePosition);
 
         if (Input.GetMouseButtonDown(0))
         {
             Instantiate(ball, ballPos, Quaternion.identity);
         }
         
     }
 }

Here is the edited version of your code:

 using UnityEngine;
 
 public class Ball : MonoBehaviour {
 
     [SerializeField] Camera mainCamera;
     [SerializeField] GameObject ball;
     public float offset; //this is the distance you want to add to z axis of your camera position
 
     // Start is called before the first frame update
     void Start() {
 
     }
 
     // Update is called once per frame
     void Update() {
         if (Input.GetMouseButtonDown(0)) {
             Vector3 ballPosition = mainCamera.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, mainCamera.transform.position.z + offset));
             ballPosition.y = 3.6f;
             Instantiate(ball, ballPosition, Quaternion.identity);
         }
     }
 }
