GamePlayTag

这里记录 gameplay tag的一些用法

获取GameplayTag最后一个节点的名字

通常最后一个节点是个经常要用的string 或者 KEY，很有用

FName UAuraAbilitySystemLibrary::GetTagLastNodeName(const FGameplayTag& Tag)
{
    if (!Tag.IsValid()) return NAME_None;
    const UGameplayTagsManager& Manager = UGameplayTagsManager::Get();
    return  Manager.FindTagNode(Tag)->GetSimpleTagName();
}

找出所有的子tag

这里返回 所有 Attribute.Primary.* 的tag

//自定义一个函数方便获取
FGameplayTagContainer RequestAllGameplayTags(const FGameplayTag ParentTag)
    {
        const UGameplayTagsManager& Manager = UGameplayTagsManager::Get();
        return Manager.RequestGameplayTagChildren(ParentTag);
    }

//或者
const UGameplayTagsManager& Manager = UGameplayTagsManager::Get();
const FGameplayTagContainer PrimaryTags = Manager.RequestGameplayTagChildren(FGameplayTag::RequestGameplayTag("Attribute.Primary", false));
