UE求职Demo开发日志#18 数据表获取物品信息，添加背包模块

1 把获取物品信息改为读取数据表

先创建结构，暂时有这几个属性：

USTRUCT(BlueprintType)
struct ARPG_CPLUS_API FMyItemData:public FTableRowBase
{
	GENERATED_USTRUCT_BODY()
	UPROPERTY(EditAnywhere, BlueprintReadWrite)
	int ItemId;//物品Id，唯一
	UPROPERTY(EditAnywhere, BlueprintReadWrite)
	int MaxOwnedCnt;//最大堆叠数量
	UPROPERTY(EditAnywhere, BlueprintReadWrite)
	FString ItemBaseName;//物品名称
	UPROPERTY(EditAnywhere, BlueprintReadWrite)
	UTexture2D* Texture;//物品图标
};

创建对应的数据表

实现Get函数：

FMyItemData UWarehouseManager::GetItemDataByItemId(int ItemId)
{
	if(!ItemDataTable)return FMyItemData();
	// 获取DataTable的所有行
	TArray<FName> RowNames= ItemDataTable->GetRowNames();

	// 遍历每一行
	for (const auto& RowName : RowNames)
	{
		FMyItemData* RowData = ItemDataTable->FindRow<FMyItemData>(RowName,FString(""),true);

		if (RowData->ItemId == ItemId)
		{
			return *RowData;
		}
	}
	return FMyItemData();
}

把原来获取Texture的地方改为用这个函数：

2 编写Bag相关代码

2.1 BagSaveData

//BagSaveData.h
#pragma once

#include "CoreMinimal.h"
#include "GameFramework/SaveGame.h"
#include "BagSaveData.generated.h"

struct FMyItemInfo;
/**
 * 
 */
UCLASS()
class ARPG_CPLUS_API UBagSaveData : public USaveGame
{
	GENERATED_BODY()
public:
	UBagSaveData();
	UFUNCTION(BlueprintCal
