试图在另一个GameObjects本地位置上设置某些东西？

Question

我正在尝试相对于另一个GameObjects本地位置设置GameObjects位置，但是我没有很多运气。通过光线投射，我可以检查播放器站在哪一侧，一切都工作正常，并且我试图根据您站在哪一侧相对于对象的本地位置创建一个变换。当不旋转此对象时，一切正常，但是当我旋转该对象时，目标位置似乎仍在世界空间中。我添加了图像来说明这种情况。

if(right)
{
    Vector3 Pos1 = _pushableT.localPosition;
    Pos1.x = _pushableT.localPosition.x + distBetween;
    _targetPos = Pos1;
}

if (left)
{
    Vector3 Pos2 = _pushableT.localPosition;
    Pos2.x = _pushableT.localPosition.x - distBetween;
    _targetPos = Pos2;
}

if (front)
{
    Vector3 Pos3 = _pushableT.localPosition;
    Pos3.z = _pushableT.localPosition.z + distBetween;
    _targetPos = Pos3;
}

if (back)
{
    Vector3 Pos4 = _pushableT.localPosition;
    Pos4.z = _pushableT.localPosition.z - distBetween;
    _targetPos = Pos4;
}

targetBallDebug.position = _targetPos;

这将适合于对象的位置，该对象看向目标，但不适用于3d空间中的旋转

using UnityEngine;

public class TrackToTarget : MonoBehaviour
{
    [SerializeField]
    private Transform target;

    private Vector3 releativePosition;
    private Quaternion targetRotationAtStartInv;
    private Quaternion rotationDiffernce;

    private void Start()
    {
        releativePosition = target.position - transform.position;
        targetRotationAtStartInv = Quaternion.Inverse(target.rotation);
        rotationDiffernce = target.rotation * transform.rotation;
    }

    private void Update()
    {
        transform.position = target.position - target.rotation * (targetRotationAtStartInv * releativePosition);
        transform.rotation = rotationDiffernce * target.rotation;
    }
}
