如果嫌在外部定义麻烦,在 C++17 可以采用 inline 来光明正大地违背 ODR,它能够告诉链接器,我想在多个 TUs 之间拥有相同的定义。 classS{//since C++17inlinestaticintx=42; }; 在C++20,由于 constexpr 会隐式 inline,所以还可以这么写: classS{//since C++20staticconstexprintx=42; }; 另外,在 C++98,...

记录一下最近做的一些 UE4 中的模型材质合并功能(这里只是记录下大致的实现思路,并不是正式的方案)。 主要介绍 StaticMesh 合并,贴图合并以及图集接缝处理等方法,这些方法经过修改之后也可以用于解决HLOD生成之类的问题。 需要解决的问题: 城市场景里摆放了很多不同的建筑,每个建筑使用 N 个材质(即模型每级 LOD N ...

最简单直接的方式便是将定义的Attribute直接应用到方法上,这个方法可以是同步的也可以是异步的,可以是实例方法也可以是静态方法,可以是属性也可以是属性getter/setter,可以是示例构造方法也可以是静态构造方法: classAbc{[Test]staticAbc(){}[Test]publicAbc(){}[Test]publicintX{get;set;}publicstaticY{[Test]get...
