我想制作一个类似学校的游戏地图，但是我并不怎么会做，应该说我不会做一个可以进出的建筑类，请各位教教我该怎么制作这类地图，感谢各位。
I want to create a game map similar to a school, but I don’t really know how to make it. I should say I don’t know how to make a building that you can go in and out of. Could everyone please teach me how to make this kind of map? Thank you all.
