UE C++ FName, FText 测试

一.FName

测试相等性，虽然存了大小写，却对大小写不敏感。equal为false。

Compare返回0，才相等。源码要转两次才看得到注释

测试表里是否已经存在了这个键值的实例，两个都找到了。这是在构造的时候找，找不到才返回0。

cpp 复制代码

void AWXStringActor::FNameTest()
{
	FName test1 = FName("StrongGWX");
	FName test2 = FName("FastGWX");
	bool equal = (test1 == test2);
	int32 a = test1.Compare(test2);
	//
	if (FName("stronggwx", FNAME_Find) != NAME_None)
	{
		int32 a1 = 1;
	}
	if (FName("fastgwx",FNAME_Find) != NAME_None)
	{
		int32 a2 = 2;
	}
}

二.FText

1.在调试时，由于FText内部时不可读的引用，所以用toString转换调试。网上还有一种Unreal.natvis 拷贝，但可能版本更新后，这个方法也咩用了。

2.代码

cpp 复制代码

#define LOCTEXT_NAMESPACE "WXStringActor"

cpp 复制代码

FText AWXStringActor::FTextChange()
{
	FText MyCodeText = LOCTEXT("OwnCode","MyCode!");
	FString Debug1 = MyCodeText.ToString();
	FText MyCodeTypeText = NSLOCTEXT("CodeTypeNameSpace","CodeType","GWXCode");
	FString Debug2 = MyCodeTypeText.ToString();
	return MyCodeText;
}

FText AWXStringActor::FTextFormat()
{
	FString PlayerName = TEXT("fgzzdXG");
	//FText PlayerText = FText::Format((LOCTEXT("PlayerNameFmt","#{0} is Really Cool"),FText::FromString(PlayerName)));
	FText PlayerText = FText::FormatNamed(LOCTEXT("PlayerNameFmt", "{PlayerName} is really cool"), TEXT("PlayerName"), FText::FromString(PlayerName));
	FString Debug1 = PlayerText.ToString();
	FText NumTexttg =  FText::AsNumber(15689.33f);
	FString Debug2 = NumTexttg.ToString();
	FText PercentTexttg = FText::AsPercent(0.33f);
	FString Debug3 = PercentTexttg.ToString();
	FText MemeoryText = FText::AsMemory(1234);
	FString Debug4 = MemeoryText.ToString();
	FText MoneyText = FText::AsCurrencyBase(650,TEXT("EUR"));
	FString Debug5 = MoneyText.ToString();
	//FText::AsDateTime();
	FDateTime MyDataTime = FDateTime::Now();
	FText TimeText = FText::AsTime(MyDataTime);

	return PlayerText;
}
