Why doesn't the object appear?
I have a "FishStar" object.
I would like to turn it off ("FishStar") for 2 seconds after the collision with the "Player" object and then turn it on again.
I use Coroutine for this.
Where is the mistake?
After adding the script (to "FishStar"), I put the object in the "otherGameObject" tab, but the object after disappearing does not want to appear again.
It's weird because if I add another object instead of otherGameObject tab (in Inspector), it works perfectly.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class FishStarRotation : MonoBehaviour {
public float speed;
private Rigidbody2D rb2D;
public GameObject Bonus;
// Use this for initialization
void Start () {
Bonus = GetComponent<GameObject>() ;
}
// Update is called once per frame
void Update () {
transform.Rotate (0, 0, speed);
}
void OnCollisionEnter2D(Collision2D coll){
if (coll.gameObject.tag == ("Player"))
StartCoroutine ( DIS ());
}
IEnumerator DIS ()
{
Bonus.SetActive(false);
yield return new WaitForSeconds(2f);
Bonus.SetActive(true);
}
}

I solved the problem.
Correct working script :
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class FishStarRotation : MonoBehaviour {
public float speed;
private Rigidbody2D rb2D;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
transform.Rotate (0, 0, speed);
}
void OnCollisionEnter2D(Collision2D coll){
if (coll.gameObject.CompareTag("Player")) {
StartCoroutine (speedUp ());
//gameObject.SetActive (false);
GetComponent<SpriteRenderer> ().enabled = false;
GetComponent<PolygonCollider2D> ().enabled = false;
// Above line will deactivate the first collider it will find.
}
}
IEnumerator speedUp ()
{
Debug.Log("before");
yield return new WaitForSeconds(2f);
Debug.Log("after");
GetComponent<SpriteRenderer> ().enabled = true;
GetComponent<PolygonCollider2D> ().enabled = true;
}
}
You are disabling the object The script is on,so script stopps running and object don't get enabled Again.Instead of disabling object just disable its collider and renderer with getComponent
