通过单击 UI 按钮而不是多次单击将游戏对象缓慢移动或缓慢移动到其他游戏对象的位置？ [复制]

Question

我的场景中有一个按钮、一个主摄像机和一个空的游戏对象。

每当我点击那个按钮时，我的相机应该会慢慢地移动到那个空游戏对象的位置。

我的相机正在移动到那个位置，这很好，但问题是我必须多次点击那个按钮，直到我的相机到达它的位置。那么有没有办法通过单击该按钮将我的相机移动到游戏对象的位置？

这是我的代码：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class TransitionCAM : MonoBehaviour {
    public Transform views;
    public float transitionSPEED;
    Transform currentVIEW;

    public void move(){
        currentVIEW = views;
        transform.position = Vector3.Lerp (transform.position, currentVIEW.position, Time.deltaTime * transitionSPEED);

        //for camera rotation
        Vector3 currentangel = new Vector3 ( Mathf.LerpAngle(transform.rotation.eulerAngles.x, currentVIEW.transform.rotation.eulerAngles.x, Time.deltaTime *transitionSPEED),
            Mathf.LerpAngle(transform.rotation.eulerAngles.y, currentVIEW.transform.rotation.eulerAngles.y, Time.deltaTime *transitionSPEED),
            Mathf.LerpAngle(transform.rotation.eulerAngles.z, currentVIEW.transform.rotation.eulerAngles.z, Time.deltaTime *transitionSPEED));

        transform.eulerAngles = currentangel;
    }
}

Answer 1

问题是您的Vector3.Lerp 只运行一次。试试这个：

    public Transform views;
    public float transitionSPEED;
    Transform currentVIEW;
    private bool flag = false;

    Vector3 currentangel;
    private void Start()
    {
        Debug.Log(flag);
        currentVIEW = views;

    }
    private void Update()
    {
        if (flag == true)
        {

            transform.position = Vector3.Lerp(transform.position, currentVIEW.position, Time.deltaTime * transitionSPEED);
            Debug.Log("object pos" + transform.position);
            Debug.Log(currentVIEW.position);
            //for camera rotation

            currentangel = new Vector3(Mathf.LerpAngle(transform.rotation.eulerAngles.x, currentVIEW.transform.rotation.eulerAngles.x, Time.deltaTime * transitionSPEED),
            Mathf.LerpAngle(transform.rotation.eulerAngles.y, currentVIEW.transform.rotation.eulerAngles.y, Time.deltaTime * transitionSPEED),
            Mathf.LerpAngle(transform.rotation.eulerAngles.z, currentVIEW.transform.rotation.eulerAngles.z, Time.deltaTime * transitionSPEED));

            transform.eulerAngles = currentangel;
        }
    }



    public void Move()
    {
        flag = true;
    }

您必须想出一种方法来在您的相机处于正确位置时停止发呆。因为按下按钮后这个if (flag == true) 将始终为真。

这是我认为使用协程的更好解决方案

public Transform views;
public float transitionSPEED;
Transform currentVIEW;
private bool flag = false;
private bool isStarted = false;
Vector3 currentangel;
private void Start()
{
    Debug.Log(flag);
    currentVIEW = views;

}
private void Update()
{
    if (flag  && !isStarted)
    {
        StartCoroutine(CoroutineSolution());
        isStarted = true;
    }
}
IEnumerator CoroutineSolution()
{
    float t = 0.0f;
    while ( t<1.0f )
    {

        t += Time.deltaTime;
        transform.position = Vector3.Lerp(transform.position, currentVIEW.position, t);

        //for camera rotation

        currentangel = new Vector3(Mathf.LerpAngle(transform.rotation.eulerAngles.x, currentVIEW.transform.rotation.eulerAngles.x, t),
        Mathf.LerpAngle(transform.rotation.eulerAngles.y, currentVIEW.transform.rotation.eulerAngles.y, t),
        Mathf.LerpAngle(transform.rotation.eulerAngles.z, currentVIEW.transform.rotation.eulerAngles.z, t));

        transform.eulerAngles = currentangel;
        Debug.Log("Coroutine running");

        yield return null;

    }

}


public void Move()
{
    flag = true;
}
