Struct or class with blueprint callable overload operators

Hello,

To simplify my project, I need to create a structure or a class with operators.

For example the operator : MyStruct operator+(int Value) const;

I’am programmer, I know how to make an overload operator in a cpp file but I have not found how to make blueprint callable overload operators.

I searched a lot on Google, I even watched how the vector structure was made​​ but nothing works.

Please somebody help me !

Tanks a lot.

I can add a snippet of code.



#pragma once

#include "Object.h"
#include "ProgressFraction.generated.h"

/**
 * 
 */

UCLASS(BlueprintType)
class UNDEADSTATE_API UProgressFraction : public UObject
{
	GENERATED_BODY()
	
public:
	UProgressFraction();
	UProgressFraction(int Current, int Max);

	/* Operators */
	FORCEINLINE UProgressFraction operator+(const UProgressFraction& F) const;
	FORCEINLINE UProgressFraction operator+(int Value) const;

	/* Displaying */
	UFUNCTION(BlueprintCallable, Category = "Displaying")
	void Dump() const;
	
	UPROPERTY(VisibleAnywhere, BlueprintReadWrite, Meta = (ExposeOnSpawn = true))
	int Current;

	UPROPERTY(VisibleAnywhere, BlueprintReadWrite, Meta = (ExposeOnSpawn = true))
	int Max;
};

FORCEINLINE UProgressFraction UProgressFraction::operator+(const UProgressFraction& F) const
{
	return UProgressFraction(Current + F.Current, Max);
}

FORCEINLINE UProgressFraction UProgressFraction::operator+(int Value) const
{
	return UProgressFraction(Current + Value, Max);
}
