How to Destory a Gameobject in C# after 3 seconds?

Archived Forums Questions & Answers

I’m trying to destroy a explosion after three seconds but my method is not working. I make the explosion after I kill the enemy in the EnemyAI script. I find the script attached to the explosion and call the function in the script to destroy the game object.

EnemyAI Script

public class EnemyAI : MonoBehaviour {

public GameObject explosion;

void Death(){

Destroy (gameObject); //kill the enemy

Quaternion randomRotation = Quaternion.Euler(0f, 0f, Random.Range(0f, 360f));
		

Instantiate(explosion, transform.position, randomRotation);

explosion.gameObject.GetComponent<DestroyItems>().DestroyExplosion();
 
}
}

DestroyItems Script

public class DestroyItems : MonoBehaviour {

	float lifetime = 3.0f;

	public void DestroyExplosion ()
	{ Destroy (gameObject, lifetime); }
}

There are no errors, but the explosion does not disappear. I get a warning saying to use DestroyImmediate(theObject, true) which I don’t want to use because it will cause problems later with missing assets in game folder.

Please avoid using IEnumerator and Coroutine in your answers. I’m just looking for something simple and I don’t need complex answers because I know there must be a easy way to do this. Thanks

using UnityEngine;
using System.Collections;

public class DestroyByTime : MonoBehaviour
{
    public float lifetime;

    void Start ()
    {
        Destroy (gameObject, lifetime);
    }
}

This is what you need.
For better understandig of how and why I suggest watching this video that will explain all you need to know to overcome youre problem:

NOTE: under the video you will see the script that I shown you here.

Use SendMessage is very helpful.

Thanks Socterean this video is one of the best tutorials I have seen. I can actually learn from it because I don’t get lost in unnecessary stuff that sometimes occurs in tutorials. I guess IEnumerator and Coroutine is not as complex as I thought well at least the way this video shows how to do it. Thanks Again!!
