Actor with time management(C++ modification)

You may need to display the time actor was created and the time it was changed. If several people are working together, you will need it more.

Implementation

C ++ code work is required.

ActorWithTimeManagement.h

// Fill out your copyright notice in the Description page of Project Settings.

#pragma once

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

UCLASS()
class TEST02_API AActorWithTimeManagement : public AActor
{
 GENERATED_BODY()
 
public: 
 // Sets default values for this actor's properties
 AActorWithTimeManagement();

 UPROPERTY()
 FDateTime BirthTime;

 UPROPERTY()
 FDateTime LastModifiedTime;

 UPROPERTY(VisibleInstanceOnly, Category = "Time", Transient)
 FString Birth;

 UPROPERTY(VisibleInstanceOnly, Category = "Time", Transient)
 FString Modified;

 UPROPERTY(VisibleInstanceOnly, Category = "Time", Transient)
 FString Passed;

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

 virtual void PostInitProperties() override;
 virtual void PostEditChangeProperty(FPropertyChangedEvent& PropertyChangedEvent) override;

 void ValidateTime();

public:

};

#include "ActorWithTimeManagement.h"


// Sets default values
AActorWithTimeManagement::AActorWithTimeManagement()
{
  // Set this actor to call Tick() every frame.  You can turn this off to improve performance if you don't need it.
 PrimaryActorTick.bCanEverTick = true;

}

// Called when the game starts or when spawned
void AActorWithTimeManagement::BeginPlay()
{
 Super::BeginPlay();
 
}

// Called every frame
void AActorWithTimeManagement::Tick(float DeltaTime)
{
 Super::Tick(DeltaTime);

}

void AActorWithTimeManagement::PostInitProperties()
{
 Super::PostInitProperties();

 ValidateTime();
}

void AActorWithTimeManagement::PostEditChangeProperty(FPropertyChangedEvent& PropertyChangedEvent)
{
 LastModifiedTime = FDateTime::Now();
 ValidateTime();

 Super::PostEditChangeProperty(PropertyChangedEvent);
}

void AActorWithTimeManagement::ValidateTime()
{
 if (BirthTime.GetYear() < 2018)
 {
  BirthTime = FDateTime::Now();
  LastModifiedTime = FDateTime::Now();
 }

 Birth.Empty();
 Birth.Append(BirthTime.ToString(TEXT("%Y.%m.%d - %h:%M %A")));

 Modified.Empty();
 Modified.Append(LastModifiedTime.ToString(TEXT("%Y.%m.%d - %h:%M %A")));

 Passed.Empty();
 Passed.Append( FString::FromInt( (int32)( FDateTime::Now() - BirthTime ).GetTotalHours() ) );
 Passed.Append(TEXT(" hour(s) passed."));
}
