已知两个直角边求夹角以及移动到目标位置

 获取角度

public float GetAngles()
    {
        float y = targetPos.y - transform.position.y;

        float x = targetPos.x - transform.position.x;

        Debug.Log(angles);
        angles = Mathf.Atan(y / x) * (180 / Mathf.PI);
        return angles;
    }

移动到目标位置

transform.Translate(Vector3.Normalize(targetPos - transform.position) * Time.deltaTime * speed * 3);
