Hey guys
I`m looking for some info on USTRUCT i cant fine much documentation on them apart from Ramas wiki, i had assumed that they were the same as Structure blueprints in the engine but in Ramas Overview of USTRUCT he is creating functions inside the USTRUCT. i also didnt understand does a USTRUCT belong to a class in its .h file or does the USTRUCT have its own .cpp/.h.
Sorry that I`m not very specific with what im asking im just looking for a point in the right direction.
Thanks guys 
USTRUCTS can contain function, like a class, but they are defaulted to public. You can define a UStruct in the header file of your class you are trying to create.
example:
inside your .h file, above your UCLASS() definition and below your #include
USTRUCT(BlueprintType)
struct FMyStruct // Nmae with prefix "F"
{
GENERATED_BODY() // must always be here first
UPROPERTY(BlueprintReadWrite, EditAnywhere, Category = "Basic") // storing a variable, with specifiers and a category
FString MyProperty = "Hello, World!";
}; // always have semicolon at end of struct definition
Hope this helps!!
