使用地图或场景信息制作文件，例如要加载的资源、对象、位置、事件
我正在使用 Visual C++ 和 DirectX 用 C++ 制作一个简单的图形引擎，并且正在测试不同的地图布局。
目前，我通过简单地制作一个 C++ 源文件并开始编写来构建“地图”：
SHADOWENGINE ShadowEngine(&settings);
SPRITE_SETTINGS sset;
MODEL_SETTINGS mset;
sset.Name = "Sprite1";
sset.Pivot = TOPLEFT;
sset.Source = "sprite1.png";
sset.Type = STATIC;
sset.Movable = true;
sset.SoundSet = "sprite1.wav"
ShadowEngine->Sprites->Load(sset);
sset.Name = "Sprite2"
sset.Source = "sprite2.png";
sset.Parent = "Sprite1";
sset.Type = ANIMATED;
sset.Frames = 16;
sset.Interval = 1000;
sset.Position = D3DXVECTOR(0.0f, (ShadowEngine->Resolution->Height/2), 0.0f);
ShadowEngine->Sprites->Load(sset);
mset.Source = "character.sx";
mset.Collision = false;
mset.Type = DYNAMIC;
ShadowEngine->Models->Load(mset);
//Etc..
我想要做的是创建地图文件，然后将其加载到引擎中，而不必将它们写入可执行文件中。这样，我就可以对地图进行更改，而不必每次都重新编译。
SHADOWENGINE ShadowEngine(&settings);
ShadowEngine->InitializeMap("Map1.sm");
我能想到的唯一方法是让它以文本形式读取文件，然后解析信息，但这听起来很麻烦。
我的想法错了吗？ 我应该怎么办？
不介意解释其他人是如何做到这一点的，比如《魔兽争霸 III》、《星际争霸》、《帝国时代》、《魔法门之英雄无敌》……
真的非常感谢对此的一些帮助。
I'm making a simple graphics engine in C++, using Visual C++ and DirectX, and I'm testing out different map layouts.
Currently, I construct "maps" by simply making a C++ source file and start writing:
SHADOWENGINE ShadowEngine(&settings);
SPRITE_SETTINGS sset;
MODEL_SETTINGS mset;
sset.Name = "Sprite1";
sset.Pivot = TOPLEFT;
sset.Source = "sprite1.png";
sset.Type = STATIC;
sset.Movable = true;
sset.SoundSet = "sprite1.wav"
ShadowEngine->Sprites->Load(sset);
sset.Name = "Sprite2"
sset.Source = "sprite2.png";
sset.Parent = "Sprite1";
sset.Type = ANIMATED;
sset.Frames = 16;
sset.Interval = 1000;
sset.Position = D3DXVECTOR(0.0f, (ShadowEngine->Resolution->Height/2), 0.0f);
ShadowEngine->Sprites->Load(sset);
mset.Source = "character.sx";
mset.Collision = false;
mset.Type = DYNAMIC;
ShadowEngine->Models->Load(mset);
//Etc..
What I'd like to be able to do, is to create map files that are instead loaded into the engine, without having to write them into the executable. That way, I can make changes to the maps without having to recompile every damn time.
SHADOWENGINE ShadowEngine(&settings);
ShadowEngine->InitializeMap("Map1.sm");
The only way I can think of is to make it read the file as text and then just parse the information, but it sounds like such a hassle.
Am I thinking the wrong way?
What should I do?
Wouldn't mind an explanation on how others do it, like Warcraft III, Starcraft, Age of Empires, Heroes of Might and Magic...
Would really appreciate some help on this one.

您的想法没有错误，加载地图数据绝对是可取的。最常见的预构建解决方案是 Protocol Buffers 和 Lua。如果您还不了解 Lua，我会使用协议缓冲区，因为它可以直接解决您的问题，而 Lua 是一种脚本语言，它足够灵活，可以完成您需要做的事情。
有些人将数据编写为 XML，但这只是部分解决方案，因为 XML 只是一种标记语言。加载 XML 后，您将有一个需要解析的 DOM 树。

You are not thinking the wrong way, loading your map data is definitely desirable. The most common prebuilt solutions are Protocol Buffers and Lua. If you don't already know Lua I would use protocol buffers, as it directly solves your problem, whereas Lua is a scripting language which is flexible enough to do what you need done.
Some people write their data as XML, but this is only a partial solution as XML is just a markup language. After loading the XML you'll have a DOM tree to parse.
