UE已经封装好了ini的读写功能，我们只需要简单几步就可以读写ini文件
这里我们选择Blueprint Function Library类型

#pragma once
#include "CoreMinimal.h"
#include "Kismet/BlueprintFunctionLibrary.h"
#include "RwTxtFiles.generated.h"
/**

UCLASS()
class SKILLDEMO_API URwTxtFiles : public UBlueprintFunctionLibrary
{
GENERATED_BODY()
public:
UFUNCTION(BlueprintCallable, Category = "Read and Write File")
static void ReadIniValue(FString Section,FString inKey, FString& outValue);
UFUNCTION(BlueprintCallable, Category = "Read and Write File")
static bool WriteIni(FString newSection, FString newKey, FString newValue);
};
// Fill out your copyright notice in the Description page of Project Settings.
#include "RwTxtFiles.h"
#include "FileHelpers.h"
void URwTxtFiles::ReadIniValue(FString Sectoin, FString inKey, FString& outValue)
{
if (!GConfig)
return;
GConfig->GetString(*Sectoin, *inKey, outValue, GGameIni);
}
bool URwTxtFiles::WriteIni(FString newSection, FString newKey, FString newValue)
{
if(!GConfig)
return false;
GConfig->SetString(*newSection,*newKey,*newValue,GGameIni);
return true
}
在GConfig便是UE封装好的，而最后一个参数GGameIni便是UE已经为我们创建好的文件，具体路径在如下：
运行后的结果：
只要将4.1的文件，拷贝到4.2并覆盖，即可在发布文件中访问我们的ini值。
