i am making a fps with multiple characters. i want the enemies to attack all players with the tag “Player”. How would i do this. i want to replace SC_Damage Reciever variable “Player” with “Player” tag so the enemy attacks all players with the tag.
using UnityEngine;
using UnityEngine.SceneManagement;

public class SC_EnemySpawner : MonoBehaviour
{
    public GameObject enemyPrefab;
    public SC_DamageReceiver Player;
 
    public Texture crosshairTexture;
    public float spawnInterval = 2; //Spawn new enemy each n seconds
    public int enemiesPerWave = 5; //How many enemies per wave
    public Transform[] spawnPoints;

    float nextSpawnTime = 0;
    int waveNumber = 1;
    bool waitingForWave = true;
    float newWaveTimer = 0;
    int enemiesToEliminate;
    //How many enemies we already eliminated in the current wave
    int enemiesEliminated = 0;
    int totalEnemiesSpawned = 0;

    // Start is called before the first frame update
    void Start()
    {
       

        //Wait 10 seconds for new wave to start
        newWaveTimer = 2;
        waitingForWave = true;
    }

    // Update is called once per frame
    void Update()
    {
        if (waitingForWave)
        {
            if (newWaveTimer >= 0)
            {

Use one of these from the GameObject class.

FindGameObjectsWithTag	Returns an array of active GameObjects tagged tag. Returns empty array if no GameObject was found.
FindWithTag	Returns one active GameObject tagged tag. Returns null if no GameObject was found.
