Question

所以我想让播放器走到某个地方，但我不希望它看起来像是在传送，所以我使用了Vector3.Slerp，但问题是它无法瞄准它会停止一半。

代码如下：

void Update()
{
    if (Input.GetKeyDown("space"))
    {
        StartCoroutine(GoToTargetPos());
    }
} IEnumerator GoToTargetPos()
{
    Vector3 targetPos = transform.position + offset;

    transform.position = Vector3.Slerp(transform.position, targetPos, Time.deltaTime * speed);

    yield return new WaitForSeconds(0.75f);

    isDone = true;
}

对不起，我的英语不好。

Answer 1

快速答案，只是为了证明它可以正常工作...

IEnumerator GoToTargetPos()
{
    Vector3 targetPos = transform.position + offset;
    float timeElapsed = 0.0f;
    float timeToMove = 0.75f; // Using this since that is how you are waiting...
    while(timeElapsed < timeToMove)
    {
       timeElapsed += Time.deltaTime;
       float ratio = Mathf.Clamp01(timeElapsed / timeToMove);
       transform.position = Vector3.Slerp(transform.position, targetPos, ratio);

       yield return null; // Return to this at the beginning of the next frame
    }
    isDone = true;
}

在协同程序中使用Slerp是一个坏主意...

如docs中所述，我建议在Slerp中使用Update：

尝试一下：

public class Moving : MonoBehaviour {

    public Vector3 offset;
    public float offsetTime = 2.0f;
    private float t = 0.0f;
    private bool moveMe = false;
    private Vector3 targetPos;
    private Vector3 startPos;

    // Use this for initialization
    void Start () {
        targetPos = transform.position + offset;
        startPos = transform.position;
        StopMoving();
    }

    public void StartMoving()
    {
        t = 0.0f;
        moveMe = true;
    }

    private void StopMoving()
    {
        t = 0.0f;
        moveMe = false;
    }

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

        if (moveMe)
        {
            t += Time.deltaTime / offsetTime;

            if(t < 1.0f)
            {
                transform.position = Vector3.Slerp(startPos, targetPos, t);
            }
            else
            {
                StopMoving();
            }
        }
    }
}

Vector3.Slerp（）停止运行而未完成其操作
