Unity:Coroutine挙動メモ

同じ Coroutine を複数回まわすと Coroutine の処理がかぶる。

myCoroutine1 の while の一回目(up++
↓
myCoroutine2 の while の一回目(up++
↓
myCoroutine1 の while の二回目(up++
↓
myCoroutine2 の while の二回目(up++
↓
.......etc

    

public class test : MonoBehaviour
{
    int up;
    // Start is called before the first frame update
    void Start()
    {
        up = 0;
        StartCoroutine(MYCoroutine(2));
    }

    // Update is called once per frame
    void Update()
    {

    }

    public IEnumerator MYCoroutine(int num)
    {
        for (int i = 0; i < num; i++)
        {
            StartCoroutine(myCoroutine(i));
            yield return null;
        }
    }

    public IEnumerator myCoroutine(int i)
    {
        while (up < 10)
        {
            up++;
            Debug.Log("i =" + i + "/ up =" + up);
            yield return new WaitForSeconds(0.07f);
        }
    }

}

連続させないようにするのも考えてみた。正しいかはわからない。
これだと
ANOTHERCoroutine1 の while 1
↓
ANOTHERCoroutine1 の while 2
↓
ANOTHERCoroutine1 の while 3
↓
...etc
ANOTHERCoroutine2 の while 1
↓
ANOTHERCoroutine2 の while 2
↓
ANOTHERCoroutine2 の while 2
↓
...etc
になる。

public class test : MonoBehaviour
{
    int up;
    int down;
    bool IsWaitingCoroutine;
    // Start is called before the first frame update
    void Start()
    {
        up = 0;
        StartCoroutine(anotherCoroutine(5));
    }

    // Update is called once per frame
    void Update()
    {

    }
    public IEnumerator anotherCoroutine(int num)
    {
        for (int i = 0; i < num; i++) 
        { 
            StartCoroutine(ANOTHERCoroutine(i,10)); 
            yield return null; 
        } 
    } 
    public IEnumerator ANOTHERCoroutine(int i,int num) { 
        while(down > 0)
        {
            yield return null;
        }
        int temp = num;
        IsWaitingCoroutine = true;
        while (temp > 0)
        {
            up++;
            temp--;
            down = temp;
            Debug.Log("i =" + i + "/ up =" + up);
            yield return new WaitForSeconds(0.07f);
        }
        IsWaitingCoroutine = false;

ちゃんと1度目の ANOTHERCoroutine が終わってから 二度目のが動いている。

これboolでもいい

public class test : MonoBehaviour
 {
 bool isWaitingCoroutine;
 int down;
 // Start is called before the first frame update
 void Start()
 {
 up = 0;
 StartCoroutine(anotherCoroutine(5));
 }
 // Update is called once per frame
 void Update()
 {
 }
 public IEnumerator anotherCoroutine(int num)
 {
 for (int i = 0; i < num; i++)
 {
 StartCoroutine(ANOTHERCoroutine(i,10));
 yield return null;
 }
 }
 public IEnumerator ANOTHERCoroutine(int i,int num) {
 while(IsWaitingCoroutine)
 {
 yield return null;
 }
 int temp = num;
 while (temp > 0)
 {
 up++;
 temp--;
 Debug.Log("i =" + i + "/ up =" + up);
 yield return new WaitForSeconds(0.07f);
 }
 }
 }
