核心需求是让炮塔对准相机指向的位置，通过射线检测（Raycast）的hit.point获取相机指向的坐标。目前相机瞄准脚本中的射线击中位置更新正常，但炮塔脚本内的目标信息始终为(0,0,0)，完全不更新。

炮塔脚本代码 #

public GameObject turret;
public GameObject camera;
public float rotationSpeed = 10f;
[SerializeField] private Vector3 targetPointInfo;

void Start() 
{

}

// Update is called once per frame
void FixedUpdate()
{
    TurretAimPointer aimpainter = camera.GetComponent<TurretAimPointer>();
    aimpainter.target = targetPointInfo;
    transform.rotation = Quaternion.Slerp(transform.rotation, Quaternion.LookRotation(targetPointInfo), rotationSpeed * Time.deltaTime);
    //TurretAim();
}

private void TurretAim()
{
    //TurretAimPointer aimpainter = camera.GetComponent<TurretAimPointer>();
    //aimpainter.target = targetPointInfo;
    //transform.rotation = Quaternion.Slerp(transform.rotation, Quaternion.LookRotation(targetPointInfo), rotationSpeed * Time.deltaTime);

    //Vector3 relativePosition = aimpainter.target - transform.position;
    //Quaternion rotation = Quaternion.LookRotation(relativePosition, Vector3.up);
    //transform.rotation = rotation;
}

相机瞄准脚本代码 #

// Start is called before the first frame update
private Camera cam;
public Vector3 target;

void Start()
{
}

// Update is called once per frame
void Update()
{
    TurretAimPaint();
}

public void TurretAimPaint()
{
    RaycastHit hit;
    Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
    if(Physics.Raycast(transform.position, Vector3.forward, out hit))
    {
        target = hit.point;
    }
}

脚本变量状态对比 #

• 相机脚本状态：target变量已正确更新为射线击中的三维坐标
• 炮塔脚本状态：targetPointInfo变量始终保持(0,0,0)，未同步相机脚本的目标点数据
