I’ve had a similar issue with structures and linking. For now, I define my structure in the gamemode header file, then if I have to use the structure in another file (.cpp/.h) then I simply add the gamemode header and use it without the using the gamemode’s namespace beforehand.
There may be a better way of doing this or TArray may attempt to do something different.
Apologies if this is a dumb question- how do you reference a UStruct as a variable type for a TArray etc? I’ve declared a USTRUCT in the GameMode class, and am referencing the type in other classes- is this possible? Obviously I’ve included the GameMode header in the classes I’m referencing it from. I’m getting an error- C2653 FMyStruct is not a class or namespace name. I’m referencing it like this;
From what I’m beginning to understand, a struct is what class inherits from. It’s defined in a single header. So you add a header to your project and put;
# pragma once
# include "FMyStructName.generated.h"
Then the rest of the struct declaration. Then you #include it wherever you use it. So its a mini class without the cpp file and you declare functions and stuff inline- if you want to have them inside the struct. (You can’t use “add code to project”).
It looks like the documentation assumes we already know this. But Stack Overflow has a load of info about structs.
Hey Green, thanks! I sorted it- see comment below. The problems were occurring when I defined it in the header file of a different class and included that classes header file. Now I’m making structs in their own header files and including them where they’re used and all is well.
