# 一、插件环境 #

## 1.1、在Editor中勾选GameplayAbility并关闭 ##

![在这里插入图片描述][20210713101929531.png]

## 1.2、在.Build.cs中添加对应模块 ##

PrivateDependencyModuleNames.AddRange(new string[] {
         "GameplayAbilities","GameplayTags","GameplayTasks" });

# 二、Character类配置 #

## 2.1、添加UAbilitySystemCompnent ##

## 2.2、并继承IAbilitySystemInterface ##

## 2.3、重写GetAbilitySystemComponent() ##

## 2.4、写一个可以让蓝图获取能力的接口AquireAbility ##
