How to change startPoin into a Players position?

I would like the startPoint to be the same position as the PLAYER object at the moment.
How to do it?

using System.Collections; 
using System.Collections.Generic; 
using UnityEngine;

 public class LaunchProjectiles : MonoBehaviour { 	

[SerializeField] 	int numberOfProjectiles; 	
[SerializeField] 	GameObject projectile; 
	Vector2 startPoint; 	
float radius, moveSpeed; 	

void Start () { 		
radius = 5f; 		
moveSpeed = 5f; 	
} 	

 	void Update () { 		
if (Input.GetButtonDown ("Fire1")) { 

startPoint = Camera.main.ScreenToWorldPoint (Input.mousePosition); 
SpawnProjectiles (numberOfProjectiles); 	

} 

	} 	

void SpawnProjectiles(int numberOfProjectiles) 
{ 	
float angleStep = 360f / numberOfProjectiles; 		

float angle = 0f; 		
for (int i = 0; i <= numberOfProjectiles - 1; i++) 

{ 	
float projectileDirXposition = startPoint.x + Mathf.Sin ((angle * Mathf.PI) / 180) * radius; 		
float projectileDirYposition = startPoint.y + Mathf.Cos ((angle * Mathf.PI) / 180) * radius; 

Vector2 projectileVector = new Vector2 (projectileDirXposition, projectileDirYposition); 			

Vector2 projectileMoveDirection = (projectileVector - startPoint).normalized * moveSpeed; 	

var proj = Instantiate (projectile, startPoint, Quaternion.identity); 	

proj.GetComponent<Rigidbody2D> ().velocity = new Vector2 (projectileMoveDirection.x, projectileMoveDirection.y); 			

angle += angleStep; 	

} 	
} 
}

The easiest way would be to have a reference of the player object in your class, then when you press the fire button you just pasa the player’s x and y position values instead of using the screenToWorldPoint function.

Solved, just simple

 startPoint = GameObject.FindGameObjectWithTag("Player").transform.position;
