How to loop IEnumerator
I'm fairly new to coding so forgive me for being dumb. I need thing code to restart itself when it reaches this --> //Keep restarting IEnumerator forever.)
using System.Collections;
using UnityEngine;
public class Thing_Head_Animator : MonoBehaviour
{
public GameObject Thing_Head_R;
public GameObject Thing_Head_L;
// Use this for initialization
void Start ()
{
StartCoroutine (Thing_Head_Animation ());
}
IEnumerator Thing_Head_Animation()
{
Thing_Head_R.SetActive (true);
yield return new WaitForSeconds (10.0f);
Thing_Head_R.SetActive (false);
Thing_Head_L.SetActive (true);
yield return new WaitForSeconds (10.0f);
Thing_Head_L.SetActive (false);
//Keep restarting IEnumerator forever.
}
}
I'm just wondering you bother setting Thing_Head_L .SetActive() to false because you end up setting it to true in the next frame. No user would be able to see the switch.
Just put whole scope into while loop
IEnumerator Thing_Head_Animation()
{
while(true) // you can put there some other condition
{
Thing_Head_R.SetActive (true);
yield return new WaitForSeconds (10.0f);
Thing_Head_R.SetActive (false);
Thing_Head_L.SetActive (true);
yield return new WaitForSeconds (10.0f);
Thing_Head_L.SetActive (false);
}
}
I would say you $$anonymous$$UST put some conditions there, because everytime I use while(true) my computer screams "No! Please, stop this! I could die here right now!".
No, there is no "must" as long as you ensure you have a yield return inside the loop. Of course a yield return that is actually reached. There is no problem having a while (true) loop. For "normal" code you just have to ensure you actually leave the loop somehow. For coroutines you just have to ensure you have a yield in between.
