Respawnscript doesn't work as expected

Questions & Answers

So i’m trying to do a simple Doom-like FPS and i wanted to implement a respawn script.

using UnityEngine;
using System.Collections;

public class Respawn : MonoBehaviour 
{
	public static Transform[] respawnPoints;
	public static Transform player;

	void Start()
	{
		player = GameObject.FindGameObjectWithTag("Player").transform;
	}

	public static void respawnAt(int randomPoint)
	{
		player.position = respawnPoints[randomPoint].position;
	}
}

This is what the respawn script looks like.

I want to activate the respawnAt method by entering a Zone

using UnityEngine;
using System.Collections;

public class FallOfMapZone : MonoBehaviour 
{
	void OnCollisionEnter(Collision col)
	{
		if(col.gameObject.transform.tag == "Player")
		{
			Respawn.respawnAt(Random.Range(1, 5));
		}
	}
}

But for some reason i get an error as soon as i go into the area: “NullReferenceExeption: Object Reference not set to an instance of an object. Respawn.respawnAt(Int32 randomPoint) (at Assets/Scripts/World/Respawn.cs:16)”

Don’t make the them static, remove static from them then you find the gameobject and call that void, this is how you could do it:

GameObject respawnObj = GameObject.Find("Respawn");
Respawn respawn = respawnObj.GetComponent<Respawn>();
int randomSpawn = Random.Range(0,5);
respawn.respawnAt(randomSpawn);
