所以，我一直在试图创建一个'Map'类来处理我的瓷砖地图在窗口上的绘制，但我有一个问题将所有的瓷砖绘制到屏幕上。用sfml绘制一个瓷砖地图
这是我的问题：可以说我有10 * 10瓦的地图，其中5层总计为10 * 10 * 5 = 500瓦（当然实时会有更多可能是瓦的10倍）这会更糟糕）...它存储在一个3D数组[层] [行] [COL]或字符，每个字符表示我的精灵表上的索引 所以我创建了一个'SpriteSheet'类来处理我的精灵表，并从索引中获取每个精灵：spriteSheet-> GetSubSprite（idx）。所以最后我有一些像Draw（spriteSheet-> GetSubSprite（（int）mapArray [i] [j] [k]））应该为每个精灵调用，每个游戏循环，所以可以说我的游戏运行在60 FPS和我有500个瓷砖画：游戏的目标是每秒画500 * 60 = 30,000（！）瓷砖...
所以你可以看到我在这里有一个问题的高招......？任何人都知道如何充分在速度方面提供这个？ （当然，对我目前的结构进行任何改进都会非常幸运）。
所以，以防万一我的SpriteSheet.cpp和我的Map.cpp文件，我知道我有很多设计错误，但请专注于我的问题，设计远没有完成。
