Question

悬停或飞行或更好的词来描述浮动。在剧本中，我现在只是将相机位置从一个地方改变到另一个地方。但相反，我希望相机浮动/悬停到下一个位置，包括地形高度变化。所以它会漂浮得很顺畅。也许我应该使用raycast？

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

public class Teleport : MonoBehaviour {

    public GameObject player;
    public Camera mainCamera;
    public Camera firstCam;
    public Camera camera;
    public bool loop;
    public bool changeDirection;
    public bool lightningBallEffect;
    public bool lookAtTarget;

    private List<GameObject> TeleportBooths;

    TeleportationsCore[] tCores;
    private int boothIndex = 0;

    private void Start()
    {
        InstantiateObjects gos = GetComponent<InstantiateObjects>();

        TeleportBooths = new List<GameObject>();
        TeleportBooths = gos.PrefabsList();
        firstCam.enabled = false;
        mainCamera.enabled = false;
        camera.enabled = true;

        tCores = TeleportBooths.Select(booth => booth.AddComponent<TeleportationsCore>()).ToArray();

        WorkingBooth();
    }

    private void WorkingBooth()
    {
        if (tCores[boothIndex].NextWorkingBooth() == true)
            boothIndex++;
        if (boothIndex == tCores.Length)
            boothIndex = 0;
        player.transform.position = TeleportBooths[boothIndex].transform.position;
camera.transform.position = new Vector3(TeleportBooths[boothIndex].transform.position.x - 15, TeleportBooths[boothIndex].transform.position.y + 15, TeleportBooths[boothIndex].transform.position.z);
camera.transform.LookAt(TeleportBooths[boothIndex].transform);

    }

    private void Update()
    {
        WorkingBooth();
    }
}

这是我试过的：

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

public class CameraFly : MonoBehaviour {

    public Camera camera;

    private Vector3 currentPos;
    private Vector3 targetPos;
    public float desiredCameraHeight;

    int movementspeed = 10;

    // Use this for initialization
    void Start ()
    {

    }

    // Update is called once per frame
    void LateUpdate ()
    {
        RaycastHit hit;
        //Ray ray = camera.ScreenPointToRay(Terrain.activeTerrain.transform.position);

        Ray ray = camera.ViewportPointToRay(Terrain.activeTerrain.transform.position);

        if (Physics.Raycast(ray, out hit))
        {
            float cameraHeight = desiredCameraHeight - hit.distance;
            targetPos.y = cameraHeight;
            transform.position += Vector3.Lerp(currentPos, targetPos, 0);
        }
    }
}

但无论是使用ScreenPointToRay还是ViewportPointToRay，相机都不会移动。

您可以使用Lerp方法将相机从位置A平滑移动到B.但是为了迎合变化的地形高度，您必须将光线投射到地面并使用光线命中距离来设置目标位置的y值。

这是一个伪代码：

//currentPos;
//targetPos;
//desiredCameraHeight;
//Racast down from camera to ground/terrain;
//cameraHeight = desiredCameraHeight - hitDistance;
//targetPos.y = cameraHeight;
//Lerp(currentPos,targetPos);

希望这有帮助

如何更改相机位置以像悬停一样移动？
