VC++:奇怪的编译器错误

Question

我正在使用DirectX在visual studio中工作,今天我遇到了一些奇怪的编译器错误(对我来说没有任何意义)......

这些是我得到的错误:

错误C2143:语法错误:缺少';' 在'.'之前 错误C2059:语法错误:')'

我已经仔细检查了我的代码并且没有发现任何错别字/错误(我可能错了......)

我希望有人可以告诉我错误通常意味着什么以及在哪里看...

我会在下面放一些代码,指出发生错误的行(如果你想检查的话)

Answer 1

在C++中,范围解析运算符::不是.; 因此,你需要使用Vertex::PosTex而不是Vertex.PosTex.
