Question

我正在统一从事高尔夫游戏，在那里我有一个摄像头根据鼠标x和y的输入绕球旋转。在我开始向球施加力之前，相机控制器代码可以正常工作。请参见下面的相机控制器代码：

void ControlCamera() 
{
    // Do Nothing if Locked
    if (cameraLocked)
        return;

    // Handle Zoom
    myCamera.transform.position = Vector3.MoveTowards(myCamera.transform.position, transform.position, Input.mouseScrollDelta.y);

    // Handle Y Transformation
    Transform yTransform = myCamera.transform;
    yTransform.RotateAround(transform.position, Vector3.left, Input.GetAxis("Mouse Y") * cameraSensitivity);
    if (yTransform.rotation.eulerAngles.x < maxXRot && yTransform.rotation.eulerAngles.x > minXRot)
    {
        myCamera.transform.rotation = yTransform.rotation;
        myCamera.transform.position = yTransform.position;
    }

    // Handle X Transformation
    myCamera.transform.RotateAround(transform.position, Vector3.down, Input.GetAxis("Mouse X") * cameraSensitivity);

    // Prevent Z Skew
    Quaternion currentRotation = myCamera.transform.rotation;
    float xRot = currentRotation.eulerAngles.x;
    float yRot = currentRotation.eulerAngles.y;
    currentRotation.eulerAngles = new Vector3(xRot, yRot, 0);
    myCamera.transform.rotation = currentRotation;
}

相机对象是球对象的子对象，并且在施加力时随球滚动。我尝试从球对象上拆下相机对象，这会破坏相机对象（它不再跟随球，因为它不再是孩子了）。

有什么想法可以使我的代码保持现在的美观和简单，并防止摄像机在跟随球的同时滚动？

Answer 1

一种解决方案可能是将gameObject 2个孩子放在球内，一个让球旋转，另一个让照相机。这样，摄像机将跟随不旋转的父gameObject（但您应该更新位置）。

另一个是我最喜欢的一个，是不要将相机放在球游戏对象上，只是从球位置更新相机位置，只是更新位置，而不是旋转即可。像这样：

让相机统一跟踪球而无需相机转动
