Question

我在c＃中为玩家动作编写了一个脚本。每当玩家按下A或D时，它将他/她向左或向右移动12个单位，当玩家按下W或S时，它将他/她向上或向下移动12个单位。我的脚本工作正常，但是如果一个人开始一次性垃圾邮件所有的密钥，它就会出现故障并且播放器对象不再与该级别保持一致。我想让脚本在按键上执行移动之前检查当前是否发生了移动。这是我的剧本：

您可以使用简单的isMoving变量。如果变量为true，请勿移动。如果是false则移动。协程完成后，将isMoving设置回false。另外，我无法说明MoveObject函数为static的原因。我从中删除了static关键字。

bool isMoving = false;

void Update()
{

    transform.Translate(Vector3.forward * ForwardSpeed * Time.deltaTime);

    if (Input.GetKeyDown(KeyCode.A) && side > maxSideLeft)
    {
        MoveObjectTo(this.transform, new Vector3(this.transform.position.x - 12, this.transform.position.y, this.transform.position.z + 10), movementSpeed);
        side -= 1;
    }
    else if (Input.GetKeyDown(KeyCode.D) && side < maxSideRight)
    {
        MoveObjectTo(this.transform, new Vector3(this.transform.position.x + 12, this.transform.position.y, this.transform.position.z + 10), movementSpeed);
        side += 1;
    }

    if (Input.GetKeyDown(KeyCode.W) && level < maxLevelHeight)
    {
        MoveObjectTo(this.transform, new Vector3(this.transform.position.x, this.transform.position.y + 12, this.transform.position.z + 10), movementSpeed);
        level += 1;
    }
    else if (Input.GetKeyDown(KeyCode.S) && level > minLevelHeight)
    {
        MoveObjectTo(this.transform, new Vector3(this.transform.position.x, this.transform.position.y - 12, this.transform.position.z + 10), movementSpeed);
        level -= 1;
    }

    if (Input.GetKeyDown(KeyCode.R) || Input.GetKeyDown(KeyCode.Space))
    {
        SceneManager.LoadScene("Scene1");
        Time.timeScale = 1;
    }
}


private void MoveObjectTo(Transform objectToMove, Vector3 targetPosition, float moveSpeed)
{
    //Don't do anything Object is already moving
    if (isMoving)
    {
        return;
    }
    //If not moving set isMoving to true
    isMoving = true;
    StartCoroutine(MoveObject(objectToMove, targetPosition, moveSpeed));
}

public IEnumerator MoveObject(Transform objectToMove, Vector3 targetPosition, float moveSpeed)
{
    float currentProgress = 0;
    Vector3 cashedObjectPosition = objectToMove.transform.position;

    while (currentProgress <= 1)
    {
        currentProgress += moveSpeed * Time.deltaTime;

        objectToMove.position = Vector3.Lerp(cashedObjectPosition, targetPosition, currentProgress);

        yield return null;
    }
    //Done moving. Set isMoving to false
    isMoving = false;
}

听起来你想要检查用户是否已经完成了他们的lerp，然后才能进入某个新位置。在这种情况下，您将希望阻止您的播放器再次移动，直到您的currentProgress变量等于1.因此，使用简单的布尔回调并阻止调用Corouting直到该回调为真。您的MoveObject功能：

public static IEnumerator MoveObject(Transform objectToMove, Vector3 targetPosition, float moveSpeed, System.Action<bool> callBack)
{
    float currentProgress = 0;
    Vector3 cashedObjectPosition = objectToMove.transform.position;

    while (currentProgress <= 1)
    {
        currentProgress += moveSpeed * Time.deltaTime;

        objectToMove.position = Vector3.Lerp(cashedObjectPosition, targetPosition, currentProgress);

        yield return null;

        if (currentProgress >= 1)
            callBack(true);
    }
}

然后您可以更改MoveObjectTo功能以阅读此回调：

private void MoveObjectTo(Transform objectToMove, Vector3 targetPosition, float moveSpeed)
{
    if (canCallCoroutine)
    {
        canCallCoroutine = false;
        StartCoroutine(MoveObject(objectToMove, targetPosition, moveSpeed, finished =>
            {
                if (finished != null)
                {
                    if (finished)
                        canCallCoroutine = true;
                }
            }));
    }
}

阻止播放器发送垃圾邮件，导致故障
