变换.位置传送。移动不顺畅

Question

简单的问题，但很难找到答案。我有一个钩子技工，按下key.B，一个钩子会发射5秒然后应该回来。这段代码工作正常，只是当分配给召回对象的代码时，它不会顺利恢复，它会传送。这是代码，粗体中的问题特定行public class Hook : MonoBehaviour{ //Remember Couroutine is pretty much update()public Transform Target;private float Thrust; // Int for motionpublic Rigidbody rb;public float HookTravelTime; //Define float for secondsbool isHookActive = false;  //Are we currently moving?public float timeHookTraveling = 0f;// Use this for initializationvoid Start(){    Thrust = 75f;    rb = GetComponent<Rigidbody>();    float walkspeed = Thrust * Time.deltaTime;}void OnCollisionEnter(Collision col){    if (col.gameObject.name == "mob")    {        Destroy(col.gameObject);        print("Other code negated");        rb.velocity = Vector3.zero;        transform.position = Vector3.MoveTowards(transform.position, Target.position, Thrust);        isHookActive = false;        timeHookTraveling = 0f;    }}void ThrowHook(){    if (Input.GetKeyDown(KeyCode.B))    {        isHookActive = true;        rb.AddForce(Vector3.forward * Thrust);    }    if (isHookActive )        {            if (timeHookTraveling >= HookTravelTime) //if the hook traveled for more than hookTravelTime(5 seconds in your case)            {            print("hehemeth");            rb.velocity = Vector3.zero; //negate addforce from before          **HERE**  transform.position = Vector3.MoveTowards(transform.position, Target.position, Thrust);            isHookActive = false;//reset this bool so your Update will not check this script until you don't activate it in your ThrowHook            timeHookTraveling = 0f;//reset the travel time for your next hook activation        }            else//if you havent hit 5 keep increasing            {                timeHookTraveling += Time.deltaTime;//increase your travel time by last frame's time            }        }    }// Update is called once per framevoid Update()    {    ThrowHook();    }}我究竟做错了什么？它应该按预期工作，对吧？

Answer 1

Vector3.MoveTowards 需要每帧运行，这就是我* Time.deltaTime在评论中提到的原因。

在 5s 时，rb 的速度变为零并isHookActive变为假，因此Vector3.MoveTowards不称为每帧。

if (Input.GetKeyDown(KeyCode.B))

{

    isHookActive = true;

    rb.AddForce(Vector3.forward * Thrust);

}

if (isHookActive )

{

    if (timeHookTraveling >= HookTravelTime) //if the hook traveled for more than hookTravelTime(5 seconds in your case)

    {

        print("hehemeth");

        rb.velocity = Vector3.zero; //negate addforce from before

        isHookActive = false;//reset this bool so your Update will not check this script until you don't activate it in your ThrowHook

        timeHookTraveling = 0f;//reset the travel time for your next hook activation

    }

    else//if you havent hit 5 keep increasing

    {

        timeHookTraveling += Time.deltaTime;//increase your travel time by last frame's time

    }

}

else if (!isHookActive && transform.position != Target.position)

{

    transform.position = Vector3.MoveTowards(transform.position, Target.position, Thrust * Time.deltaTime);

}

一个更好的方法是把

if (Input.GetKeyDown(KeyCode.B))

{

    isHookActive = true;

    rb.AddForce(Vector3.forward * Thrust);

}

进入FixedUpdate()但不是Update()同时

if (isHookActive )

{... }

留在Update().
