How to do it...

We'll create a structure called FColoredTexture in C++ code to contain a texture and a modulating color:

1. From Visual Studio, right-click on the Games/Chapter_02/Source/Chapter_02 folder and select Add | New item.... From the menu, select a Header file (.h) and then name the file ColoredTexture.h (not FColoredTexture).
2. Under Location, make sure that you select the same folder as the other script files in the project (in my case, C:\Users\admin\Documents\Unreal Projects\Chapter_02\Source\Chapter_02) that is not the default:

1. Once created, use the following code in ColoredTexture.h:

#pragma once 

#include "ObjectMacros.h"
#include "ColoredTexture.generated.h"
 
USTRUCT(Blueprintable) 
struct CHAPTER_02_API FColoredTexture 
{
  GENERATED_USTRUCT_BODY()

public: 
  UPROPERTY( EditAnywhere, BlueprintReadWrite, Category = HUD ) 
  UTexture* Texture; 

  UPROPERTY( EditAnywhere, BlueprintReadWrite, Category = HUD ) 
  FLinearColor Color; 
}; 

1. Use ColoredTexture.h as a UPROPERTY() in a blueprintable UCLASS(), using a UPROPERTY() declaration such as this:

#include "CoreMinimal.h"
#include "UObject/NoExportTypes.h"
#include "ColoredTexture.h"
#include "UserProfile.generated.h"


/**
 * UCLASS macro options sets this C++ class to be
 * Blueprintable within the UE4 Editor
 */
UCLASS(Blueprintable, BlueprintType)
class CHAPTER_02_API UUserProfile : public UObject
{
  GENERATED_BODY()

public:
  UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = Stats)
  float Armor;

  UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = Stats)
  float HpMax;

  UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = Stats)
  FString Name;

  // Displays any UClasses deriving from UObject in a dropdown 
  // menu in Blueprints
  UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = Unit)
  TSubclassOf<UObject> UClassOfPlayer; 

  // Displays string names of UCLASSes that derive from
  // the GameMode C++ base class
  UPROPERTY(EditAnywhere, meta=(MetaClass="GameMode"), Category = Unit )
  FStringClassReference UClassGameMode;

  // Custom struct example
  UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = HUD) 
  FColoredTexture Texture; 
};

1. Save your script and compile your changes. Upon entering your object blueprint, you should notice the new properties:
