使用 AddExplosionForce 时无法将类型“float”隐式转换为“UnityEngine.Vector3”

每当我按下空格键时，我都希望有一个带有 z 轴偏移的爆炸力作用于我的播放器。但是，它给了我错误：无法将类型“float”隐式转换为“UnityEngine.Vector3”

if (Input.GetKeyDown("space"))
        {
            Vector3 rocketLoc = new Vector3(transform.position.x, transform.position.y, transform.position.z);
            rocketLoc.x = rocketLoc.x + 20.00f;
            rb.AddExplosionForce(20.00f, rocketLoc, 20.00f, 20.00f, ForceMode.Impulse);
            StartCoroutine(WaitAfterBlast());
        }
