waitforseconds not working c#

[Simpson95]

hi!

i made a script to move a platform from point to poin, but i’d like it to stop for X seconds in each point.

the object where the script goes has an empty object as patent, the actual platform as the first child and N empty game objects that are used to set the points where the platform have to go. it works perfectly, but doen’t stops when reaches a point and goes immediately to the next.

here is the code:

`using UnityEngine;
using System.Collections;

public class Platform : MonoBehaviour {

public bool bTurnOnOff = false;
public float fSpeed = 2.0f;
public float fWaitTime = 5.0f;

private int n;

void Start () {
	n = 2;
}

void Update () {
	if (bTurnOnOff == true) {
		transform.GetChild(0).localPosition = Vector3.MoveTowards (transform.GetChild(0).localPosition, transform.GetChild(n).localPosition, fSpeed * Time.deltaTime);
		ChangePos ();
	}
}
void ChangePos () {
	if (transform.GetChild(0).localPosition == transform.GetChild(n).localPosition){
		if (n <= transform.childCount-1){
			n = n + 1;
		}
		if (n > transform.childCount-1){
			n = 1;
		}
		StartCoroutine (Wait());
	}
}
IEnumerator Wait () {
	yield return new WaitForSeconds (fWaitTime);
}

}
`

what am i doing wrong?

You’re using the coroutine wrong. You can’t cause another method to wait just because you start a coroutine that waits. You need to wait in the method that returns IEnumerator. Ex:

IEnumerator ChangePos()
{
    if (transform.GetChild(0).localPosition == transform.GetChild(n).localPosition)
        n = n <= transform.childCount-1 ? n + 1 : 1;
    yield return new WaitForSeconds(waitTime);
}

Except, in your case, you’d be calling this method potentially every frame, then waiting for something. Also, what were you waiting for? Did you intend your Update loop to not run during the wait? If that’s the case, then either don’t run your code from the Update Loop (i.e. start a coroutine in the Start or Awake method instead), or control it with a conditional.

If you explain what you’re trying to accomplish I (and others, perhaps) can help you get things working the way you want.
