Type	Name
	GridObject () = default
	GridObject (std::string asset_name, int x, int y)
	GridObject (const GridObject & other) 複本不屬於任何 GridEngine。
void	Move (int dx, int dy)
virtual void	OnCollide (GridObject * other) 與另一個可見物件位於同一個有效網格座標時呼叫。
virtual void	OnSpawn () 物件加入引擎後呼叫一次。
virtual void	OnUpdate () 每幀更新時呼叫。
virtual void	Render (GridEngine * engine) 繪製物件。預設使用物件的素材、方向與顏色繪製所在格。

GridObject &	operator= (const GridObject & other) = delete
void	set_asset_name (const std::string & asset_name)
void	set_direction (int direction) 每增加 1 逆時針旋轉 90 度；輸入會正規化至 0 到 3。
void	set_tag (const std::string & tag)
void	set_tint (Color tint)
void	set_visible (bool visible) 隱藏的物件仍會更新，但不會繪製或參與碰撞。
void	set_x (int x)
void	set_y (int y)
void	set_z_index (int z_index) 數值越大越晚繪製；相同數值保持 Spawn 順序。
