Creating a Blueprint implementable function in C++

Development Programming & Scripting Blueprint

So, I know there are tons of questions out there asking the same thing, but i cannot seem to get anything to work.

This is what i tried:

Playercharacter.h

UFUNCTION(BlueprintNativeEvent)
	void SetInventoryItemsGUI_Implementation(TArray<FText> items);

PlayerCharacter.cpp

void APlayerCharacter::SetInventoryItemsGUI_Implementation(TArray<FText> items){

}

I am getting these errors:

\HorrorGame\Intermediate\Build\Win64\UE4Editor\Inc\HorrorGame\HorrorGame.generated.cpp(160): error C2511: 'void APlayerCharacter::SetInventoryItemsGUI_Implementation(const TArray<FText,FDefaultAllocator> &)' : overloaded member function not found in 'APlayerCharacter'

\HorrorGame\Source\HorrorGame\PlayerCharacter.h(18) : see declaration of 'APlayerCharacter'

HorrorGame.generated.cpp(163): error C2352: 'UObject::FindFunctionChecked' : illegal call of non-static member function

c:\program files\epic games\4.9\engine\source\runtime\coreuobject\public\uobject\UObject.h(752) : see declaration of 'UObject::FindFunctionChecked'

At base declaration, you declere native event without _Implementation surrfix

UFUNCTION(BlueprintNativeEvent)
void SetInventoryItemsGUI(TArray<FText> items);

UHT will generate _Implementation deceleration automatically so you don’t need to declare it, but in farther subclasses you override implementation using the surrfix like this:

virtual void SetInventoryItemsGUI_Implementation(TArray items) override;

and always you define (code) function with that surrfix where ever you use it, so don’t change anything in cpp

I just tried this, and yet im getting the same error

4

change argument to as error say that generated code wants

const TArray<FText> items

or

TArray<FText>& items

AH, its magic, it works, I tried making it a static function. Cant believe I didnt think of that, thanks

6

actually its not showing up in the blueprint

7

I also tried changing it to a BlueprintImplementableEvent, and then got rid of everything in the .cpp file

8

Where do you looking? do you look for event or function override? if you dont see in one it will be in another. If i remeber right it depends on if your function return anything or not

I checked both, and then searched it, but I will check again, I also tried searching it by right clicking and putting in the name

turns out hot reload does not work, its in there now

Ok :slight_smile: yea hot reload is buggy
