统一跟随玩家时更改相机位置

Question

我在 Unity 3D 中创建了一个行走角色，我观看了一个教程来制作一个让玩家跟随相机的脚本，这很好，但我希望相机做得更低并向后旋转更多，以便相机可以看到更多的世界，因为现在没有多少可见的通过玩家。我附上了一个链接，指向它现在的样子。

接下来我将附上脚本，希望您能告诉我需要添加或更改哪些代码才能使我的更改成为可能。

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

    public class CameraFollow : MonoBehaviour
{
public Transform playerObject;

public float distanceFromObject = 6f;
void Update()
{
    Vector3 lookOnObject = playerObject.position - transform.position;
    lookOnObject = playerObject.position - transform.position;
    transform.forward = lookOnObject.normalized;

    Vector3 playerLastPosition;
    playerLastPosition = playerObject.position - lookOnObject.normalized * distanceFromObject;

    playerLastPosition.y = playerObject.position.y + distanceFromObject / 2;
    transform.position = playerLastPosition;
}

提前感谢您帮助我。这是一个学校项目，所以我真的希望你的解决方案很棒，迫不及待地想收到你的来信！

您正在考虑为相机添加相对于相机观察位置的偏移量。您需要做的是在将playerObject.position 分配给lookOnObject 时抵消它。

添加一个新的vector3并将其命名为lookOffset。现在它将变为lookOnObject = (playerObject.position + lookOffset) - transform.position。它将充当您相机的俯仰控制。

使用distanceFromObject控制相机的z轴位置。

这是我修改后的脚本。如上所述，您需要偏移相机将要看到的位置。在这个脚本中，我使用了 float，而不是 Vector3：

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

public class CameraFollow : MonoBehaviour
{
    public Transform playerObject;

    //Controls the pitch of the camera where it rotates
    //in X axis
    public float pitchOffset = 0;

    //Controls the yaw of the camera where it rotates
    //in Y axis
    public float yawOffset = 0;

    public float distanceFromObject = 6f;
    void Update()
    {
        //Creation of the look offset relative to the
        //Observable position
        Vector3 lookOffset = playerObject.position;
        lookOffset.y += pitchOffset;
        lookOffset.x += yawOffset;

        Vector3 lookOnObject = playerObject.position - transform.position;
        //Replaced playerObject.position with lookOffset
        lookOnObject = lookOffset - transform.position;
        transform.forward = lookOnObject.normalized;


        Vector3 playerLastPosition;
        //Replaced playerObject.position with lookOffset
        playerLastPosition = lookOffset - lookOnObject.normalized * distanceFromObject;

        playerLastPosition.y = playerObject.position.y + distanceFromObject / 2;
        transform.position = playerLastPosition;
    }
}

可以使用 Vector3 或 Vector2 来完成，您将 pitchOffset 和 yawOffset 存储到 x 和 y 字段。
