我从一个有一年历史的统一线程中提取了大部分代码。每当我运行它时，我的相机都会很快在负 z 方向上运行。我整天都在研究变量，但没有什么能让我点击它。

z 每帧变化 5 个单位，这正是我为相机距离设置的。这似乎是理解问题的关键。我的部分问题是我几乎不能使用变换和欧拉角来掌握移动的物体。感谢您的时间。

public GameObject cameraTarget = null;

public float cameraSpeedX = 120.0f; //x sensitivity
public float cameraSpeedY = 120.0f; //y sensitivity
public float cameraVelocityX = 0.0f;
public float cameraVelocityY = 0.0f;
public float cameraRotationX = 0.0f;
public float cameraRotationY = 0.0f;

public float cameraLimitMinY = -20f;
public float cameraLimitMaxY = 80f;

public float cameraDistance = 5.0f;
public float cameraDdistanceMin = 0.5f;
public float cameraDistanceMax = 15.0f;

// Use this for initialization
void Start () {
    gameObject.AddComponent<MeshFilter>();
    gameObject.AddComponent<MeshRenderer>();
    Vector3 angles = transform.eulerAngles;
    cameraRotationX = angles.x;
    cameraRotationY = angles.y;

    // Make the rigid body not change rotation
    if(GetComponent<Rigidbody>()){GetComponent<Rigidbody>().freezeRotation = true;}
    cameraTarget = gameObject;

}

void LateUpdate(){
    if (cameraTarget){
        if (Input.GetMouseButton(1)){
            cameraVelocityX += cameraSpeedX * Input.GetAxis("Mouse X") * 0.02f;
            cameraVelocityY += cameraSpeedY * Input.GetAxis("Mouse Y") * 0.02f;
        }

        cameraRotationY += cameraVelocityX;
        cameraRotationX -= cameraVelocityY;

        cameraRotationX = ClampAngle(cameraRotationX, cameraLimitMinY, cameraLimitMaxY);

        //Quaternion fromRotation = Quaternion.Euler(transform.rotation.eulerAngles.x, transform.rotation.eulerAngles.y, 0);
        Quaternion toRotation = Quaternion.Euler(cameraRotationX, cameraRotationY, 0);
        Quaternion rotation = toRotation;

        Vector3 negDistance = new Vector3(0.0f, 0.0f, -cameraDistance);
        Vector3 position = rotation * negDistance + cameraTarget.transform.position;

        transform.rotation = rotation;
        transform.position = position;

        cameraVelocityX = Mathf.Lerp(cameraVelocityX, 0, Time.deltaTime * 2.0f);
        cameraVelocityY = Mathf.Lerp(cameraVelocityY, 0, Time.deltaTime * 2.0f);

        print ("POSITION:"+transform.position);
    }
}

public static float ClampAngle(float angle, float min, float max){
    if (angle < -360F)
        angle += 360F;
    if (angle > 360F)
        angle -= 360F;
    return Mathf.Clamp(angle, min, max);
}

出于某种原因，我认为将相机脚本和游戏对象生成放在同一个对象中是个好主意。相机变换被应用于自身，这导致相机无休止地试图落后于自己。感谢 mprivat 的洞察力。
