GameObject cube = GameObject.Find("CubeTest");    
transform.LookAt(cube.transform);
transform.Translate(transform.forward * Time.deltaTime * approachSpeed);
transform.RotateAround(cube.transform.position, Vector3.up,20000*Time.deltaTime);

我想那能如你所愿吗？它逐渐向旋转点移动，然后旋转，给人一种恶化轨道的感觉。

从this blog post .我构建了以下可配置脚本：

public class SpiralMovement : MonoBehaviour
{
    [SerializeField] Transform moveable;
    [SerializeField] public Transform destiny;
    [SerializeField] float speed;
    
    // As higher as smoother approach, but it can not be more than 90, or it will start getting away.
    [SerializeField][Range(0f, 89f)] float angle = 60f;

    void Update()
    {
        Vector3 direction = destiny.position - moveable.position;
        direction = Quaternion.Euler(0, 0, angle) * direction;
        float distanceThisFrame = speed * Time.deltaTime;

        moveable.transform.Translate(direction.normalized * distanceThisFrame, Space.World);
    }
}
