Problem Delegate declaration VS 2022

[mustang4484]

Hi guys
I’ve a problem with this declaration of delegate on my VS 2022:

#pragma once

#include "CoreMinimal.h"
#include "GameFramework/Actor.h"
#include "MyActorTT.generated.h"

DECLARE_MULTICAST_DELEGATE_OneParam(FOnScoreChanged, float, NewScore); 
UCLASS()
class TESTRTS_API AMyActorTT : public AActor
{
		GENERATED_BODY()
	
public:	
	UPROPERTY(BlueprintAssignable)
	FOnScoreChanged OnScoreChange;
	// Sets default values for this actor's properties
	AMyActorTT();
	

protected:
	// Called when the game starts or when spawned
	virtual void BeginPlay() override;

public:	
	
	// Called every frame
	virtual void Tick(float DeltaTime) override;

};

This is the error: TestRTS/MyActorTT.h(16) : Error: Unrecognized type ‘FOnScoreChanged’ - type must be a UCLASS, USTRUCT, UENUM, or global delegate.

I’ve try to build solution, delete old sln and generate a new,etcc…
Some problem when use dynamic delegate.

Any solution?

Thank you!!

You need to use the DYNAMIC variants of delegates in order to be used with UPROPERTY. Dynamic delegates have support for serialization that regular delegates do not have. What error do you get when you use those?
