給Zombunny加一個tag，腳本用

p3玩家可以圍着Zombunny轉，僅僅是演示

p4鼠標控制player轉向，wasd控制移動

添加quad改名爲floor，鼠標每次點擊會落到floor上（腳本實現）

添加layer的floor

並移除floor的component

寫floor的腳本

    public float speed = 6f;

        floorMask = LayerMask.GetMask("Floor");

        movement.Set(h, 0f, v);
        movement = movement.normalized * Time.deltaTime * speed;     // 比喻：1秒顯示60FPS畫面
        playerRigidbody.MovePosition(transform.position + movement); // player的座標加上移動
    }

            Vector3 forward = floorHit.point - transform.position;
            forward.y = 0f;
            Quaternion lookQuaternion = Quaternion.LookRotation(forward);
            playerRigidbody.MoveRotation(lookQuaternion);
        }

        //Vector3 forward = enemyTransform.position - enemyTransform.position; // player和enemy的距離
        //Quaternion lookQuaternion = Quaternion.LookRotation(forward); // unity計算player對enemy的forward
        //playerRigidbody.MoveRotation(lookQuaternion); 
    }
