yield WaitForSeconds unexpected symbol

Question

Hello All. I'm currently adding some functionality to the first "Roll A Ball" application as I learn Unity for the first time. I wanted to display the Win text for X number of seconds so I found the yield WaitForSeconds function. The issue is that the compiler in MonoDevelop-Unity application gives me an error:

 Assets/Scripts/PlayerController.cs(13,17): error CS0246: The type or namespace name `List`1' could not be found. Are you missing a using directive or an assembly reference?

All I did was add this to the "SetCountText()" function as below:

     void SetCountText(){
         countText.text = "Count: " + count.ToString ();
         if (count >= 17) {
             winText.text = "This game is terrible. You should get a refund.";
             yield WaitForSeconds(5f);
         }
     }

Any ideas? Am I missing some special namespace or something? I'm currently using: using UnityEngine; using System.Collections; using System.Collections.Generic; using UnityEngine.UI;

WaitForSeconds is a class, so it needs to be instantiated with the 'new' keyword. Try this:

 yield return new WaitForSeconds(5f);

Also, it only works in a function that supports it, namely a function that returns IEnumerator. Check this article out for more info.

using UnityEngine; using System.Collections; using System.Collections.Generic; using UnityEngine.UI;

public class PlayerController : $$anonymous$$onoBehaviour {

 public float speed;
 public Text countText;
 public Text winText;

 private int count;

 private List<GameObject> disabledObjects = new List<GameObject>();

 private Rigidbody rb;

 void Start(){
     rb = GetComponent<Rigidbody> ();
     count = 0;
     SetCountText ();
     winText.text = "";
     StartCoroutine (checkEnd());
 }

 // Physics code. Called before physics calculations
 void FixedUpdate(){
     float moveHorizontal = Input.GetAxis ("Horizontal");
     float moveVertical = Input.GetAxis ("Vertical");

     Vector3 movement = new Vector3 (moveHorizontal, 0.0f, moveVertical);

     rb.AddForce (movement*speed);
 }

 void Update(){
     if (count >= 17) {
         // reset game
         count = 0;
         rb.$$anonymous$$ovePosition(new Vector3 (0.0f, 0.5f, 0.0f));
         SetCountText ();
         foreach (GameObject a in disabledObjects) {
             a.SetActive (true);
         }
     }
 }

 void OnTriggerEnter(Collider other){
     if (other.gameObject.CompareTag("Pickup")){
         other.gameObject.SetActive(false);
         disabledObjects.Add (other.gameObject);
         count++;
         SetCountText ();
     }
 }

 void SetCountText(){
     countText.text = "Count: " + count.ToString ();
 }

 IEnumerator checkEnd(){
     if (count >= 17) {
         winText.text = "This game is terrible. You should get a refund.";
         yield return new WaitForSeconds (5.0f);
         winText.text = "";
     }
 }

}

Did you read the article I linked to? It tells you how to start coroutines properly. Hint: It's how you're calling the method.

Yep. I tried calling checkEnd(), StartCoroutine(checkEnd()) as well as StartCoroutine("checkEnd"); - Like in updated code in previous comment (I Edited it). And it still doesn't seem to work.

hey, none of this worked? well, try this one...

     IEnumerator WaitForSec(float secounds)
     {
     Debug.Log("our wait has started");
     yield return new WaitForSeconds(secounds);
     Debug.Log("our wait has started");
     }
