前言

本篇文章记录了在学习GAS系统之后将其应用到战棋游戏的一个案例，供自己复习使用，第三者观看需有一定UE的cpp基础。

在本demo中实现了战棋游戏的角色属性设计，等级成长系统，战斗系统（包含回合切换，FillFloud算法来计算移动范围，A*算法来实现寻路功能，结合蓝图实现平滑移动，根据角色AP值进行行动间的转换）等战棋游戏的大多数内容设计，其中技能系统采用GAS实现，将GAS的秒计时器改造为回合计时器，从而使得GAS的cooldown可以应用到回合制上，参考虚幻GAS回合制

角色基础功能

此处不再重复实现基础功能，基本在蓝图中实现，感兴趣的小伙伴可以自行搜索

GAS插件的使用 配置GameplaySystemAbility

1.先去UE中下载插件GameplayAbility和GameplayTagsEditor
2.重启后在VS工程中的bulid.cs文件中配置数据(添加"GameplayAbilities",“GameplayTags”）

using UnrealBulidTool;

public class Study : ModuleRules
{public Study(ReadOnlyTargetRules Target):base(Target)
	{PCHUsage = PCHUsageMode.UseExplicitOrSHaredPCHs;

		PublicDependencyModuleNames.AddRange(new string[]{"Core","CoreUObject","Engine","InputCore","HeadMountedDisplay","GameplayAbilities","GameplayTags"});
	}
};

3.在CharacterBase.h的代码如下

#include "CoreMinimal.h"
#include "GameFrameWork/Character.h"
#include "AbilitySystemInterface.h"
#include "AbilitySystemComponent.h"
#include "Abilities/GameplayAbility.h"//这三个头文件是配置GAS的必要文件

#include "CharacterBase.generated.h"//此处头文件包含为系统自带，且之后要包含的头文件都必须在此头文件之前

插队算法根据AP计算棋子行动顺序

思路：
1：先对AP降序排列
2：由AP大的行动，行动之后AP值减少，存入NextAPList
3：在CurAPList【0】行动之前，将NextAPList中每个元素与之比较，若AP相差为2倍以上，则插队
4：插队的方法是将Next中的元素插在Cur的元素之前
5：重复执行2-3
6：当AP为0时将其清除
7：重复1-6，直至Next和Cur全部为空，结束回合
8：回合开始，重新赋予AP

void AMyTurnMaps::UpdateAPList()

A*算法计算最短移动距离

思路：

1：首先创建两个集合openList和closeList（openList用于存放可以走的路，closeList存放已经走过的路（即不能走的
路，包含障碍物））

2：将起点加入openList中，使用一个workCell变量用于开拓道路。首先取出openList中的第一个元素
存放到workCell中。此时进行判断，若workCell等于终点，流程结束。否则进行3

3：将openList中的第一个元素即workCell从openList中删除，并加入到closeList中，表示这是走过的路。

4：找到workCell的所有邻居，用一个临时变量neighboursList存放，对neighboursList【i】进行判断，
若该邻居在closeList集合中，表示该邻居是走过的，直接跳过，否则进行5

5：若neighboursList【i】不在openList中，表示没有计算过F，计算F，并将neighboursList【i】的父
节点设置为workCell，然后将该邻居加入到openList中，加入的时候进行判断，当F最小时放openList
首位（保证最短路径）
否则，neighboursList【i】在openList中（表示曾经计算过F），执行6

6：重新计算F，若重新计算的值比之前计算的值小，则更新F和G以及父节点。

7：重复执行2-6，直到openList中没有元素（表示没有通路）

8：若成功找到通路，则用终点来回溯寻找父节点，将每个父节点存到pathList集合中，最终该集合就是通路。

FillFloud算法计算棋子可移动范围

思路：

1：定义一个movePathList作为存放可移动的范围，在originCell中添加CellCost作为走过该格子需要的消耗，添加
surplusLimit作为走到该格子还剩余的行动力

2：首先将起点加入movePathList'中，将起点的surplusLimit更新为传入的行动力

3：定义变量checkCell，顺序获得movePathList中的元素，求出checkCell的邻居

4：遍历邻居，对每个邻居进行一次检查，判断当前行动力是否可以移动到该邻居

5：如果可以，将该邻居加入到movePathList中，如果该邻居已经在movepathList中，判断此时的limit是否大于
movepathlist中的surplus，如果大于则将当前的limt更新进movepathlist

6：重复进行3-5，当movepathlist中的元素遍历完毕时，退出循环
//获得移动路径
void AMyTurnMaps::GetMovePathList(AOriginCell* checkCell)
{ClearMovePathList();

	IGetAttributeInterface* inter = Cast(checkCell->GetCurrentActor());

	checkCell->surplusLimit = limit;
	for(int i = 0;i< movePathList.Num(); i++)
	{checkCell = movePathList[i];
		TArrayneighbourList = FindNeighbours(checkCell);
		for(int j = 0;j< neighbourList.Num();j++)

		}
		movePathList[i]->MoveHigh();
	}
}
