我目前没有用clang编译。用vs编译出来的exe单独运行没有报错，调试就崩溃，断点无法命中。需要在cmake中设置调试符合相关的吗？

怎么没有同步更新

Dear Team,
This is an amazing project.
Thanks for putting so much effort to make this tutorial a reality in the first place!

I like this project so I want to follow along and create my own game at the end but I am really afraid of using C++ as the dev language because I do think I can do memory management correctly.

In the mean time I am also aware that not all existing eco system is there for Rust so I wanted to know what is the most important support needed if I were to port this project from C++ to Rust?

I do not know either language well so my question is probably too much of an ask.
Can someone please with enough context either help me find the minimum set of work needs to be done or help me ask the right question?

Thanks in advance, really appreciate the work here, I am already grateful for what the project has been offering at the moment.

void* My::MemoryManager::Allocate(size_t size, size_t alignment)
{
uint8_t* p;
size += alignment;
Allocator* pAlloc = LookUpAllocator(size);
if (pAlloc)
p = reinterpret_cast<uint8_t*>(pAlloc->Allocate());
else
p = reinterpret_cast<uint8_t*>(malloc(size));

p = reinterpret_cast<uint8_t*>(ALIGN(reinterpret_cast<size_t>(p), alignment));

return static_cast<void*>(p);

}

您好，这里有个地方我有点疑问，不知道对不对。
p = reinterpret_cast<uint8_t*>(ALIGN(reinterpret_cast<size_t>(p), alignment));
这里对Allocator返回出来的指针可能会做对齐的移动操作，但是在free的时候没有看到移回之前的位置，不知道会不会有问题

如题，应该是每章代码都有tag吧

把代码全部拉取下来后，执行./build-xcode.sh，每次都报错：

感谢您的代码，学习受教了。
1.我在windows平台编译通过了，也可以运行。
2.在Ubuntu 20下，也安装各种库后，只有最后的最后，Test/BulletTest.cpp 的25行
btCollisionShape* groundShape = **new btStaticPlaneShape(btVector3(0.0f, 1.0f, 0.0f), 1);**编译失败，提示：undefined reference to `btStaticPlaneShape::btStaticPlaneShape(btVector3 const&, double)'
collect2: error: ld returned 1 exit status
另外一个工程：Game/Billiard也是同样的错误。
我看了一下大约是部分内容引用float,部分引用了double，不知怎么修改。
3.我临时屏掉这两个工程，编译通过，我用Viewer工程进行测试，发现运行时Initialize崩溃，崩到：GameEngineFromScratch/Platform/Linux/OpenGLApplication.cpp的156行，int default_screen = DefaultScreen(m_pDisplay);，我也分析了一下，这个时间理论上m_pDisplay = nullptr,理论上强转到结构体，的确会崩。
下面是堆栈，刚启动，比较简单，我这边必现的。
My::OpenGLApplication::CreateMainWindow(My::OpenGLApplication * const this) (/GameEngineFromScratch/Platform/Linux/OpenGLApplication.cpp:156)
My::BaseApplication::Initialize(My::BaseApplication * const this) (/GameEngineFromScratch/Framework/Common/BaseApplication.cpp:20)

谢谢，祝好。
