I am trying to say if the Y of my player reaches below 0 change the players position to 0,1,0 it wont work thought and I tried using Vector3 but it says I cant use Vector3 like a method Please help!

Here is my code If your wondering I'm making a 3D game about a player dodging blocks.

 using UnityEngine;
 public class RSet : MonoBehaviour

   {
  public GameObject player = null;
   
     // Start is called before the first frame update
 void Start()
  {
     
  }

 // Update is called once per frame
 void Update()
  {
    if(player.transform.player.y < 0) {
    player.transform.position = Vector3(0,1,0);
      }
   }
 }
 

,This is my code...

using UnityEngine;

public class RSet : MonoBehaviour

{

 public GameObject player = null;
   
     // Start is called before the first frame update
 void Start()
 {
     
 }

 // Update is called once per frame
 void Update()
 {
    if(player.transform.player.y < 0) {
    player.transform.position = Vector3(0,1,0);
    }
 }
