在继续使用C＃Unityfunction之前，请等待协程完成

我正在努力让一个单位在Unity2d中通过网格移动。 我让运动没有问题。 我希望函数MovePlayer等到协程完成后再继续，所以程序将等到玩家完成移动后再发出更多订单。

这是我的代码：public class Player：MonoBehaviour {

public Vector3 position; private Vector3 targetPosition; private float speed; void Awake () { speed = 2.0f; position = gameObject.transform.position; targetPosition = position; GameManager.instance.AddPlayerToList(this); //Register this player with our instance of GameManager by adding it to a list of Player objects. } //Function that moves the player, takes a list of nodes as path public void MovePlayer(List path) { StartCoroutine(SmoothMovement(path)); //Next step should wait until SmoothMovement is finished } private IEnumerator SmoothMovement(List path) { float step = speed * Time.deltaTime; for (int i = 0; i  float.Epsilon) { transform.position = Vector3.MoveTowards(transform.position, targetPosition, step); sqrRemainingDistance = (transform.position - targetPosition).sqrMagnitude; yield return null; } position = transform.position; } }

您不能等待主线程中的函数中的协程，否则您的游戏将冻结，直到您的函数结束。

为什么不在你的协程结束时给你的下一步打电话？

 private IEnumerator SmoothMovement(List path) { float step = speed * Time.deltaTime; for (int i = 0; i < path.Count; i++) { targetPosition = new Vector3(path[i].coordinatesX, path[i].coordinatesY, 0f); float sqrRemainingDistance = (transform.position - targetPosition).sqrMagnitude; while (sqrRemainingDistance > float.Epsilon) { transform.position = Vector3.MoveTowards(transform.position, targetPosition, step); sqrRemainingDistance = (transform.position - targetPosition).sqrMagnitude; yield return null; } position = transform.position; } //Next Step }
