Question

我正在运行一些协同程序，每隔几秒就会将对象从一个位置移动到另一个位置。在某个时刻，我想禁用他们的对手。如何确保每个游戏对象都已完成＆＃39; lerping＆＃39;在禁用它的对撞机之前到新位置，以防止在飞跃过程中禁用对撞机？以下是相关代码：

    IEnumerator moveObjToRight  (Transform fromPosition, Vector3 toPosition, float duration, int newIndex)  {


            while (freePositions.Contains(objPositions[newIndex])) {

            freePositions.Add (objPositions [newIndex - 1]);
            filledPositions.Remove (objPositions [newIndex - 1]);

            float counter = 0;

        Transform startTrans = fromPosition;

        freePositions.Remove (objPositions [newIndex]);
        filledPositions.Add (objPositions [newIndex]);

            while (counter < duration) {                
                counter += Time.deltaTime;
                fromPosition.position = Vector3.Lerp (startTrans.position, toPosition, counter / duration);
                yield return null;

            }


            if (newIndex < objPositions.Count) {

                newIndex++;

                if ((newIndex == 9) || !freePositions.Contains (objPositions [newIndex]))   {

                isMovingLeft = true;

                yield return new WaitForSeconds (2.0f);

                if (freePositions.Contains (objPositions [newIndex - 2])) {

                toPosition = new Vector3(objPositions[newIndex - 2], startTrans.position.y, startTrans.position.z );
                yield return StartCoroutine(moveObjToLeft(startTrans, toPosition, 1.0f, newIndex - 2));

                }

                else if (!freePositions.Contains (objPositions [newIndex - 2])) {
                    yield return new WaitForSeconds (3.0f);

                    toPosition = new Vector3(objPositions[newIndex - 2], startTrans.position.y, startTrans.position.z );
                    yield return StartCoroutine(moveObjToLeft(startTrans, toPosition, 1.0f, newIndex - 2));


                }
            }
        }

        startTrans.position = toPosition;
        toPosition = new Vector3 (objPositions [newIndex], startTrans.position.y, startTrans.position.z);

        int waitTime = Random.Range (3, 5);
        yield return new WaitForSeconds (waitTime);

    }
}

IEnumerator LerpWithCompletionAction(Action onCompletion){
    while(Vector3.Distance(this.transform.position, this.target.position)<0.001f)       
    {
          // Lerp
          yield return null
    }
    if(onCompletion != null) { onCompletion(); }
}

检查使用距离，因为您无法真正依赖于检查浮动比较。您可以降低检查值或增加检查值是否过早发生，或者是否因为太小而不会发生。

然后你这样打电话：

void DisableColliders(){  // Disable your colliders }

void AnyMethod()
{
    StartCoroutine(LerpWithCompletionAction(DisableColliders));
}

如何在禁用collider2d之前确保lerp已结束
