Compiling problem UE\VS2022

Sorry I wasn’t clear. The other errors I was getting were because the attribute getter and setter weren’t defined by the macro anymore. All I did was this:

// Uses macros from AttributeSet.h

//#define ATTRIBUTE_ACCESSORS(ClassName, PropertyName) \
//
//	GAMEPLAYATTRIBUTE_PROPERTY_GETTER(ClassName, PropertyName) \
//
//	GAMEPLAYATTRIBUTE_VALUE_GETTER(PropertyName) \
//
//	GAMEPLAYATTRIBUTE_VALUE_SETTER(PropertyName) \
//
//	GAMEPLAYATTRIBUTE_VALUE_INITTER(PropertyName)

Today I replaced these macros manually with the code and it compiled fine.

Here are the macros from the AttributeSet.h file:

#define GAMEPLAYATTRIBUTE_PROPERTY_GETTER(ClassName, PropertyName) \
	static FGameplayAttribute Get##PropertyName##Attribute() \
	{ \
		static FProperty* Prop = FindFieldChecked<FProperty>(ClassName::StaticClass(), GET_MEMBER_NAME_CHECKED(ClassName, PropertyName)); \
		return Prop; \
	}

#define GAMEPLAYATTRIBUTE_VALUE_GETTER(PropertyName) \
	FORCEINLINE float Get##PropertyName() const \
	{ \
		return PropertyName.GetCurrentValue(); \
	}

#define GAMEPLAYATTRIBUTE_VALUE_SETTER(PropertyName) \
	FORCEINLINE void Set##PropertyName(float NewVal) \
	{ \
		UAbilitySystemComponent* AbilityComp = GetOwningAbilitySystemComponent(); \
		if (ensure(AbilityComp)) \
		{ \
			AbilityComp->SetNumericAttributeBase(Get##PropertyName##Attribute(), NewVal); \
		}; \
	}

#define GAMEPLAYATTRIBUTE_VALUE_INITTER(PropertyName) \
	FORCEINLINE void Init##PropertyName(float NewVal) \
	{ \
		PropertyName.SetBaseValue(NewVal); \
		PropertyName.SetCurrentValue(NewVal); \
	}

I just replaced the macros with this code for each attribute and it compiled fine:

/** Current Mana, used to execute special abilities. Capped by MaxMana */

UPROPERTY(BlueprintReadOnly, Category = "Abilities", ReplicatedUsing = OnRep_Mana)

FGameplayAttributeData Mana;

//ATTRIBUTE_ACCESSORS(UDGAttributeSet, Mana)

static FGameplayAttribute GetManaAttribute()
{
	static FProperty* Prop = FindFieldChecked<FProperty>(UDGAttributeSet::StaticClass(), GET_MEMBER_NAME_CHECKED(UDGAttributeSet, Mana));
	return Prop;
}


FORCEINLINE float GetMana() const
{
	return Mana.GetCurrentValue();
}


FORCEINLINE void SetMana(float NewVal)
{
	UAbilitySystemComponent* AbilityComp = GetOwningAbilitySystemComponent();
	if (ensure(AbilityComp))
	{
		AbilityComp->SetNumericAttributeBase(GetManaAttribute(), NewVal);
	};
}


FORCEINLINE void InitMana(float NewVal)
{
	Mana.SetBaseValue(NewVal);
	Mana.SetCurrentValue(NewVal);
}

I’m just not sure why it went wrong. All these macros are autogenerated by UE.
