将相机移向目标游戏对象并旋转

标签: c# unity3d

我在场景中有6个不同的按钮,有6个不同的空游戏对象。当我单击按钮1时,摄像头将移向游戏对象1并根据目标游戏对象旋转自身,但是当摄像头移向第三游戏对象时,我的摄像头将以不同的随机方式以及不同的随机旋转方式开始移动,这是由于浮点t = 0.0f;在代码中,例如当我调用public void Wallview()时,我的相机移向对象3,但它开始以随机旋转的不同随机方式移动,请帮助我

大多数答案是重复。仍将其完全重写以供其他读者使用。

您可以采用points的数组,如以下脚本所示。 另外,为了保持相机的位置,我采用了变量currentPointIndex只是为了保持当前点的索引。

要正确旋转,请在协程内部使用Quaternion.RotateTowards();,如下面的代码所示

CameraMotion.cs

public Transform[] points;
public int currentPointIndex=0;
public Transform lookAtTarget;

private void Update()
{
    if (Input.GetKeyDown(KeyCode.Space))
    {
        StartCoroutine(CameraTransition(points[currentPointIndex],1.0f));
        currentPointIndex++;
    }
}

IEnumerator CameraTransition(Transform nextPoint,float time)
{
    float i = 0;
    float rate = 1 / time;

    Vector3 fromPos = transform.position;

    while (i<1)
    {
        i += Time.deltaTime * rate;
        transform.position = Vector3.Lerp(fromPos,nextPoint.position,i);


        Quaternion targetRotation = Quaternion.LookRotation(nextPoint.position-transform.position);
        transform.rotation = Quaternion.RotateTowards(transform.rotation,targetRotation,i);

        yield return 0;
    }
}}

基本上,我们在数组点上循环并相应地过渡。

或者,如果您的点不是线性形式(在数组中),则可以相应地修改逻辑。但是您可以使用相同的协同例程。

我建议做些更好的事情,首先不要对事情进行硬编码,以允许它接受更多对象。第二,坚持使用更简单的解决方案。

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

public class LookAtObject : MonoBehaviour {

public float Speed = 0.001f;
private Transform _go;

// Update is called once per frame
void Update ()
{
    if (_go == null) return;

    Vector3 direction = _go.transform.position - transform.position;
    Quaternion toRotation = Quaternion.FromToRotation(transform.forward, direction);
    transform.rotation = Quaternion.Lerp(transform.rotation, toRotation, Speed * Time.time);
}

public void AdjustOrientation(Transform go)
{
    _go = go;
}
}


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

public class OnClick : MonoBehaviour
{
private LookAtObject _lookAt;


public void Start()
{
    _lookAt = FindObjectOfType<LookAtObject>();
}

public void Update()
{
    if (Input.GetMouseButtonDown(0))
    {
        var ray = Camera.main.ScreenPointToRay(Input.mousePosition);
        RaycastHit hit;

        if (Physics.Raycast(ray, out hit, 100))
        {
            //optionally if(hit.collider.tag != "MyTag") return;
            _lookAt.AdjustOrientation(hit.transform);
        }
    }
}
}

将这些类放置在相机上,发生的事情是第一类它通过您想要通过AdjustOrientation观察的对象所需要的东西。填充后,Update会查看该对象。

第二个类使您可以单击场景中包含刚体并且是运动学的任何对象。单击该对象后,它将设置AdjustOrientations,使照相机查看该对象,您可以轻松地向您的gameObject添加标签,并声明是否hit.collider.tag ==“ LookAt”然后允许其查看。
