1 实现思路设计

定义一个结构体记录技能树一个单元的信息，命名为FStrengthenCellInfo，一个TArray记录技能树整体信息，需要以下信息：

1.TArray前置技能index

2.FString 描述文本

3.TArray<FMyItemInfo>激活需要的物品ID和数量

4.bool 是否已经激活

一个新的Save类记录技能树信息

强化条件：所有前置技能激活，消耗物品全部都够

强化时：扣除消耗物品-->修改属性-->保存属性-->更新技能树信息-->保存技能树信息-->更新UI显示

设计一个道具用来测试，ID：1 DisplayName：源能结晶 CurrentOwnedCnt：1000

2 实现过程

2.1 UStrengthenInfoSave

用来保存数据的类，实现了GetSet

.cpp:

// Fill out your copyright notice in the Description page of Project Settings.#include "StrengthenSystem/StrengthenInfoSave.h"TArray<FStrengthenCellInfo> UStrengthenInfoSave::GetStrengthenTreeInfo()
{return StrengthenTreeInfo;
}
void UStrengthenInfoSave::SetStrengthenTreeInfo(TArray<FStrengthenCellInfo> InStrengthenTreeInfo)
{StrengthenTreeInfo = InStrengthenTreeInfo;
}

.h:

// Fill out your copyright notice in the Description page of Project Settings.#pragma once#include "CoreMinimal.h"
#include "GameFramework/SaveGame.h"
#include "Items/WarehouseManager.h"
#include "StrengthenInfoSave.generated.h"USTRUCT(BlueprintType)
struct ARPG_CPLUS_API FStrengthenCellInfo
{GENERATED_USTRUCT_BODY()UPROPERTY(EditAnywhere, BlueprintReadOnly)TArray<int32> PreIndex;UPROPERTY(EditAnywhere, BlueprintReadOnly)FString DescriptionText;UPROPERTY(EditAnywhere, BlueprintReadOnly)TArray<FMyItemInfo> NeededItems;UPROPERTY(EditAnywhere, BlueprintReadOnly)bool bIsActive=false;FStrengthenCellInfo(){PreIndex=TArray<int32>();NeededItems=TArray<FMyItemInfo>();DescriptionText = FString("Default");bIsActive=false;}
};
/*** */
UCLASS()
class ARPG_CPLUS_API UStrengthenInfoSave : public USaveGame
{GENERATED_BODY()
private:TArray<FStrengthenCellInfo> StrengthenTreeInfo;
public:UFUNCTION(BlueprintCallable)TArray<FStrengthenCellInfo> GetStrengthenTreeInfo();UFUNCTION(BlueprintCallable)void SetStrengthenTreeInfo(TArray<FStrengthenCellInfo> InStrengthenTreeInfo);
};

呜呜出现了一个难以解决的bug，正在努力找。。。，改完回来更新

（1.22补充）2.2 UStrengthenManager

继承的UObject

实现了下边这几个函数：

Save、Load读取和保存到文件里

GetStrengthedCellInfo是按照index读取技能树里的一个单位的信息，这里暂时只有一个技能树，就是这个StrengthedTree_1

UPROPERTY(EditDefaultsOnly)TArray<FStrengthenCellInfo> StrengthenTree_1;UFUNCTION(BlueprintCallable)void Save();UFUNCTION(BlueprintCallable)void Load();UFUNCTION(BlueprintCallable)FStrengthenCellInfo GetStrengthenCellInfo(int index);

具体实现：

void UStrengthenManager::Save()
{UStrengthenInfoSave* SaveData=Cast<UStrengthenInfoSave>(UGameplayStatics::CreateSaveGameObject(UStrengthenInfoSave::StaticClass()));SaveData->SetStrengthenTreeInfo(StrengthenTree_1);UGameplayStatics::SaveGameToSlot(SaveData,FString("StrengthenInfo"), 0);
}void UStrengthenManager::Load()
{UStrengthenInfoSave* SaveData=Cast<UStrengthenInfoSave>(UGameplayStatics::LoadGameFromSlot(FString("StrengthenInfo"), 0));StrengthenTree_1=SaveData->GetStrengthenTreeInfo();
}
FStrengthenCellInfo UStrengthenManager::GetStrengthenCellInfo(int index)
{if(index>=0&&index<StrengthenTree_1.Num()){return StrengthenTree_1[index];}return FStrengthenCellInfo();
}

还有就是测试用的技能树在构造的时候初始化了：

	FStrengthenCellInfo SCI_1=FStrengthenCellInfo();SCI_1.bIsActive = false;SCI_1.DescriptionText=FString("BaseAttack+10");TArray<FMyItemInfo>NeededItems;NeededItems.Add(FMyItemInfo(1,10,FString("源能结晶")));SCI_1.NeededItems=NeededItems;SCI_1.PreIndex=TArray<int32>();StrengthenTree_1.Add(SCI_1);SCI_1.bIsActive = false;SCI_1.DescriptionText=FString("MaxHealth+100");NeededItems.Empty();NeededItems.Add(FMyItemInfo(1,15,FString("源能结晶")));SCI_1.NeededItems=NeededItems;SCI_1.PreIndex={0};StrengthenTree_1.Add(SCI_1);SCI_1.bIsActive = false;SCI_1.DescriptionText=FString("BaseResistance+10");NeededItems.Empty();NeededItems.Add(FMyItemInfo(1,15,FString("源能结晶")));SCI_1.NeededItems=NeededItems;SCI_1.PreIndex={0};StrengthenTree_1.Add(SCI_1);

（1.22补充）2.3 UUserWidget_StrengthenPad中的修改

添加了一个接口函数来调用Manager里的Get：

FStrengthenCellInfo UUserWidget_StrengthenPad::GetStrengthenCellInfoInterface(int index)
{if(!StrengthenManager)StrengthenManager=NewObject<UStrengthenManager>();if(StrengthenManager!=nullptr){return StrengthenManager->GetStrengthenCellInfo(index);}return FStrengthenCellInfo();
}

强化的核心是这个函数：

所有的需要物品的数量都够了才能进行强化

强化属性

移除消耗物品

更新UI信息

保存数据

//TODO：前置技能条件检查

bool UUserWidget_StrengthenPad::TryStrengthenByCellIndex(int index)
{if(!WarehouseManager){UE_LOG(LogTemp,Warning,TEXT("WarehouseManager ptr in UUserWidget_StrengthenPad is Not Valid"));return false;}FStrengthenCellInfo temp=StrengthenManager->GetStrengthenCellInfo(index);bool bCanStrengthen=true;for(int i=0;i<temp.NeededItems.Num();i++){int OwnedCnt=WarehouseManager->GetItemInfoByItemId(temp.NeededItems[i].ItemId).CurrentOwnedCnt;if(temp.NeededItems[i].CurrentOwnedCnt>OwnedCnt)//需要的比有的大，则不能强化{bCanStrengthen=false;}}if(bCanStrengthen){//这里处理强化逻辑，注意不要错if(index==0){StrengthenByName(FString("BaseAttack"),10);for(int i=0;i<temp.NeededItems.Num();i++){WarehouseManager->RemoveItemFromWarehouse(temp.NeededItems[i].ItemId,temp.NeededItems[i].CurrentOwnedCnt);}WarehouseManager->SaveData();UpdatePadInfo();SaveToSlot();return true;}if(index==1){StrengthenByName(FString("MaxHealth"),100);for(int i=0;i<temp.NeededItems.Num();i++){WarehouseManager->RemoveItemFromWarehouse(temp.NeededItems[i].ItemId,temp.NeededItems[i].CurrentOwnedCnt);}WarehouseManager->SaveData();UpdatePadInfo();SaveToSlot();return true;}if(index==2){StrengthenByName(FString("BaseResistance"),10);for(int i=0;i<temp.NeededItems.Num();i++){WarehouseManager->RemoveItemFromWarehouse(temp.NeededItems[i].ItemId,temp.NeededItems[i].CurrentOwnedCnt);}WarehouseManager->SaveData();UpdatePadInfo();SaveToSlot();return true;}return false;}return false;
}
