[游戏开发]UE中Csv配置器

蓝图配置器

1. 准备csv格式配置文件

1. 创建蓝图struct,命名为FSpeakerInfoLine,导入表配置,得到Speaker的DataTablet

????????

1. 使用配置数据

   1. 创建UI并把其中的文本bind为SpeakerChoice的变量

1. 在GameMode中显示UI和获得SpeakerController的引用,通过对象引用进行初始化

1. InitSpeakerController:SpeakerController进行初始化,通过Speacker类型的array的Speackers设置Speaker中的SpeakerController

调用UpdataUI,更新UI

1. UpdateUI:通过活动上述datatablet的speaker的数据,来显示在最后的UI上

4. c++实现

CsvPaster.h继承Actor,然后派生出蓝图类,拖到场景中就调用了

public:	
	// Sets default values for this actor's properties
	ACsvPaster();

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

public:	
	// Called every frame
	virtual void Tick(float DeltaTime) override;

	UDataTable* HudTextDataTable = nullptr;

};

CsvPaster.cpp

#include "CsvPaster.h"
#include "Serialization/Csv/CsvParser.h"
//#include"CsvDataCenter.h"
// Sets default values
ACsvPaster::ACsvPaster()
{
 	// 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;
	HudTextDataTable = LoadObject<UDataTable>(NULL, UTF8_TO_TCHAR("DataTable'/Game/Data/Cabinett.Cabinett'"));
	check(HudTextDataTable);
}

// Called when the game starts or when spawned
void ACsvPaster::BeginPlay()
{
	Super::BeginPlay();
	FHudTextCsvRow* dataRow = HudTextDataTable->FindRow<FHudTextCsvRow>(TEXT("2"), TEXT(""));
	if (dataRow)
	{
		GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Red, dataRow->ShortDescription);
		GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Red, dataRow->LongDescription);
		//GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Red, dataRow->Price);
	}
}

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

}

导入的数据必须是通过这个HudTextCsvRow结构

?

?字段标签必须与struct中的属性相同命名
