Hey there!

I have this custom blueprint player controller class with these events:

This blueprint class inherits from a C++ class. I want to move their declaration to the C++ class, but I have no idea.

How can I declare them in C++?

Thanks.

Variables, Functions, Dispatchers, Events

I have moved all the event dispatcher to a C++ class:

DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FOnMoveActionDelegate, float, ActionValue);
DECLARE_DYNAMIC_MULTICAST_DELEGATE(FOnSpeedUpActionDelegate);
DECLARE_DYNAMIC_MULTICAST_DELEGATE(FOnRotateActionDelegate);
DECLARE_DYNAMIC_MULTICAST_DELEGATE(FOnEnableRunCodeButtonDelegate);

/**
 * 
 */
UCLASS()
class TETRIS_API ATCommonPlayerController : public APlayerController
{
	GENERATED_BODY()

public:
	UPROPERTY(BlueprintAssignable)
	FOnMoveActionDelegate OnMoveAction;

	UPROPERTY(BlueprintAssignable)
	FOnSpeedUpActionDelegate OnSpeedUpAction;

	UPROPERTY(BlueprintAssignable)
	FOnRotateActionDelegate OnRotateAction;

	UPROPERTY(BlueprintAssignable)
	FOnEnableRunCodeButtonDelegate OnEnableRunCodeButton;
};

Then, I have created a BP class that inherits from ATCommonPlayerController. On this new Blueprint class, I want to do this with the C++ event OnMoveAction:

But I can’t. This is what I get when I try to call it:

How can I call it from blueprint?

I did it changing BlueprintAssignable with BlueprintCallable:


DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FOnMoveActionDelegate, float, ActionValue);
DECLARE_DYNAMIC_MULTICAST_DELEGATE(FOnSpeedUpActionDelegate);
DECLARE_DYNAMIC_MULTICAST_DELEGATE(FOnRotateActionDelegate);
DECLARE_DYNAMIC_MULTICAST_DELEGATE(FOnEnableRunCodeButtonDelegate);

/**
 * 
 */
UCLASS()
class TETRIS_API ATCommonPlayerController : public APlayerController
{
	GENERATED_BODY()

public:
	UPROPERTY(BlueprintCallable)
	FOnMoveActionDelegate OnMoveAction;

	UPROPERTY(BlueprintCallable)
	FOnSpeedUpActionDelegate OnSpeedUpAction;

	UPROPERTY(BlueprintCallable)
	FOnRotateActionDelegate OnRotateAction;

	UPROPERTY(BlueprintAssignable)
	FOnEnableRunCodeButtonDelegate OnEnableRunCodeButton;
};
