Here's my GameMaster script:

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

public class GameMaster : MonoBehaviour

{

public static GameMaster gm;

public CameraShake camShake; //reference to the camera shake

public float spawnCamShakeAmount = 0.05f;

public float spawnCamShakeDuration = 0.1f;

void Awake()

{

if (gm == null)

{

gm = this; //so we have a static variable called "gm" and we set it equal to this instance of the game master class if it's not already set

}

void Start()

{

camShake = GameMaster.gm.GetComponent<CameraShake>();

if (camShake == null)

{

Debug.LogError("No CameraShake script found on GM object.");

}

//variable containing reference to player Prefab

public GameObject playerPrefab;

//variable containing reference to spawn point

public Transform spawnPoint;

//create an integer containing seconds to delay before respawning

public float spawnDelay = 2f;

//variable containing reference to particle spawn prefab

public GameObject spawnPrefab; //don't need to use Transform if we're not going to access the Transform component (such as Transform.position), which we're not in this case

//underscore to signify that this is a LOCAL method, not a STATIC method

public IEnumerator _RespawnPlayer() //IEnumerator is a "coroutine" which allows the function to be delayed before being called (in the "yield return new" line below

{

//play the respawn audio clip which has been dragged onto the _GM

GetComponent<AudioSource>().Play();

yield return new WaitForSeconds(spawnDelay); //waits for the given number of seconds (determined by the spawnDelay variable) before respawning

Instantiate(playerPrefab, spawnPoint.position, spawnPoint.rotation); //instantiate player

camShake.Shake(spawnCamShakeAmount, spawnCamShakeDuration);

GameObject clone = Instantiate(spawnPrefab, spawnPoint.position, spawnPoint.rotation);

Destroy(clone, 3f); //this destroys the instantiated particles (which we've called "clone", which is standard practice for a briefly instantiated game object) after 3s

}

public static void KillPlayer(Player player) //function which accesses the Player class (which we made in the Player script), and we're calling the player "player"

{

Destroy(player.gameObject);

gm.StartCoroutine(gm._RespawnPlayer()); //calls the RespawnPlayer method defined above

}

public static void KillEnemy(Enemy enemy)

{

gm._KillEnemy(enemy); //call the _KillEnemy method we created below

}

public void _KillEnemy(Enemy _enemy) //underscore to signify that this is a LOCAL method, not a STATIC method

{

//initiate enemy death particles, at the enemy position, with no additional rotation

GameObject _clone = Instantiate(_enemy.deathParticles, _enemy.transform.position, Quaternion.identity) as GameObject;

//destroy the enemy death particles after 5 seconds

Destroy(_clone, 5f);

camShake.Shake(_enemy.enemyCamShakeAmount, _enemy.enemyCamShakeDuration);

Destroy(_enemy.gameObject);

}
