首先通过Datatable的FindRowUnchecked根据RowName获取到当前的Row的指针 uint8* RowPtr = DataTable->FindRowUnchecked(FName("YourRowName")); 再用GetRowStruct获取到我们蓝图的Struct的CPP父类 const UScriptStruct* ScriptStruct = DataTable->GetRowStruct() ...
常规做法中，通过DataTable的FindRowUnchecked函数根据RowName获取Row指针，进而使用GetRowStruct函数获取蓝图中Struct的C++父类。然后，通过内部的PropertyLink迭代属性，从而获取所有属性名称。接下来，根据Class进行if判断，以识别当前属性值为声明类型。实现这一过程的关键代码如下：代码示例：通过反射机制获取Data...

1、在 UE4 中使用 zip 库的时候编译遇到以下问题: if (!has_seeded) srand(GetTickCount()^(unsigned long)GetDesktopWindow()); error C4302: “类型强制转换”: 从“HWND”到“unsigned long”截断。GetDesktopWindow() 为 HWND 类型,是一个 ...
如果用蓝图做还容易错,正好最近在学UEC++,不如查查看有没有什么用C++批量改参数的方法,在论坛一顿搜索之后发现了这篇(https://forums.unrealengine.com/t/reading-struct-attributes-in-c/471834/2),又看到了大钊老师在知乎上InsideUnreal中对反射的讲解(https://zhuanlan.zhihu.com/p/61042237),那不如用C++整...
