Hi,
I’m in need of getting a class reference by string.
As such node does not exist in blueprints, I built one through c++:
UClass* UClassLoader::LoadClass(FString className)
{
LoadObject<UClass>(ANY_PACKAGE,*className);
return FindObject<UClass>(ANY_PACKAGE, *className);
}
MasterGrunt is the name of one of my classes.
However, when I run the code, Unreal crashes with this stack:
Access violation - code c0000005 (first/second chance not available)
