[UE4]自定义结构体、类、数据表

自定义数据表：

#pragma once

#include "CoreMinimal.h"
#include "Engine/UserDefinedStruct.h"
#include "Components/CanvasPanel.h"
#include "Blueprint/UserWidget.h"
#include "Runtime/Engine/Classes/Engine/UserDefinedStruct.h"
#include "Runtime/Engine/Classes/Engine/DataTable.h"
#include "Runtime/CoreUObject/Public/UObject/ObjectMacros.h"

#include "MiniMapFlagData.generated.h"


/*BlueprintType：暴露成为蓝图数据类型，蓝图变量可以使用该结构体作为数据类型*/
USTRUCT(BlueprintType)
struct FUMiniMapFlagDataC : public FTableRowBase
{
    GENERATED_USTRUCT_BODY()

    //小图标
    UPROPERTY(EditAnywhere, BlueprintReadWrite)
        UUserWidget* flag;

    //小图标对应的Actor
    UPROPERTY(EditAnywhere, BlueprintReadWrite)
        AActor* Actor;

    //小图标对应的Canvas panel Slot
    UPROPERTY(EditAnywhere, BlueprintReadWrite)
        UCanvasPanelSlot* Slot;

    UPROPERTY(EditAnywhere, BlueprintReadWrite)
        int MyAge;
