unity中vr相机的无论朝向哪都保持视角在物体的后面的代码

你可以通过以下代码实现相机视角在物体后面：

public class CameraController : MonoBehaviour
{
    public Transform target;
    public float distance = 5.0f;
    public float height = 1.0f;
    public float damping = 2.0f;
    public bool smoothRotation = true;
    public float rotationDamping = 10.0f;

    void LateUpdate()
    {
        Vector3 wantedPosition = target.TransformPoint(0, height, -distance);
        transform.position = Vector3.Lerp(transform.position, wantedPosition, Time.deltaTime * damping);

        if (smoothRotation)
        {
            Quaternion wantedRotation = Quaternion.LookRotation(target.position - transform.position, target.up);
            transform.rotation = Quaternion.Slerp(transform.rotation, wantedRotation, Time.deltaTime * rotationDamping);
        }
        else
        {
            transform.LookAt(target, target.up);
        }
    }
}

将以上代码添加到一个空的游戏对象上，将要跟随的物体（如人物）作为target传递给CameraController组件。然后调整distance和height参数来控制相机与物体之间的距离和高度。通过调整damping和rotationDamping参数可以控制相机跟随时的平滑度。
