UE4数据表结构错误
UE4数据表结构错误
提问于 2017-08-01 20:20:50
我正在学习有关CSV表条目的Packt教程。本教程要求我a)创建一个新的Actor类，b)命名为TestCustomData，c)用以下代码替换新生成的TestCustomData.h的内容：
#pragma once
#include "TestCustomData.generated.h"
USTRUCT(BlueprintType)
struct FTestCustomData : public FTableRowBase
{
GENERATED_USTRUCT_BODY()
UPROPERTY( BlueprintReadOnly, Category = "TestCustomData" )
int32 SomeNumber;
UPROPERTY( BlueprintReadOnly, Category = "TestCustomData" )
FString SomeString;
};但是，TestCustomData文件无法编译，输出了以下日志：
Error f:\unreal\ue4 assignments\ue4_projectrpg\source\ue4_projectrpg\TestCustomData.h(5) : error C2504: 'FTableRowBase': base class undefined

我被困在同一个地方，这个问题解决了:我把资产命名为"MyActor2“和结构"ThisNewStructure”，所以有一些小的区别。
我认为基本包括Datatable.h和“公众”，这就成功了。
头文件：
#pragma once
#include "CoreMinimal.h"
#include "GameFramework/Actor.h"
#include "Runtime/Engine/Classes/Engine/DataTable.h"
#include "MyActor2.generated.h"
USTRUCT(BlueprintType)
struct FThisNewStructure : public FTableRowBase
{
GENERATED_USTRUCT_BODY()
public:
UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = test)
int32 SomeNumber;
UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = test)
FString SomeString;
};cpp：
#include "MyActor2.h"然后编译成功。我不得不关闭/重新打开VS & UE的编辑器，以了解新的结构。

可能有点晚了，但我自己也碰上了。有时候你会有一个自动抓取FTableRowBase的包含，但有时一个类没有一个能够调用它的头。在这种情况下：
#pragma once
#include "Engine/DataTable.h"//this is where FTableRowBase is declared.
#include "TestCustomData.generated.h"
struct FFoo : FTableRowBase
{
GENERATED_USTRUCT_BODY()
public:
the rest of your class...我希望这能帮上忙！

谢谢你的帮助，我在同一个教程中解决了同样的问题。显然，您不需要将TestCustomData重命名为MyActor2，只需在"GENERATED_USTRUCT_BODY()“之后添加"public:”行。
