虚幻引擎5 GAS开发俯视角RPG游戏 P06-31 映射标签到属性

news 2025/11/4 8:46:03

1.在小部件里添加标签,当标签一致时,修改对应的结果:

细节:

2.在属性集里添加映射CC_AttributeSet.h

Map(标签, 获取属性的方法指针)

/** 模板函数:* 别名: 静态函数指针* 用途: 1. TMap(指针,属性)*/
template<class T>
using TStaticFuncPtr = typename TBaseStaticDelegateInstance<T, FDefaultDelegateUserPolicy>::FFuncPtr;

	/** TMap(指针,属性)*/TMap<FGameplayTag, TStaticFuncPtr<FGameplayAttribute()>> TagsToAttributes;

这段代码定义了虚幻引擎5 GAS系统中用于将游戏标签映射到属性访问函数的类型声明。

TStaticFuncPtr是一个模板别名，它指向TBaseStaticDelegateInstance的静态函数指针类型FFuncPtr，这是UE委托系统中用于绑定静态函数的核心类型。

TagsToAttributes是一个TMap容器，键为FGameplayTag游戏标签，值为返回FGameplayAttribute的静态函数指针。这种设计允许通过游戏标签动态查找对应的属性访问函数，为属性菜单UI提供数据支持。

在属性集构造函数里添加映射CC_AttributeSet.cpp:

UCC_AttributeSet::UCC_AttributeSet()
{TagsToAttributes.Add(CC_GameplayTags::Attributes_Primary_Agile, GetAgileAttribute);TagsToAttributes.Add(CC_GameplayTags::Attributes_Primary_Intelligence, GetIntelligenceAttribute);TagsToAttributes.Add(CC_GameplayTags::Attributes_Primary_Strength, GetStrengthAttribute);TagsToAttributes.Add(CC_GameplayTags::Attributes_Primary_Vigor, GetVigorAttribute);TagsToAttributes.Add(CC_GameplayTags::Attributes_Secondary_Armor, GetArmorAttribute);TagsToAttributes.Add(CC_GameplayTags::Attributes_Secondary_ArmorPenetration, GetArmorPenetrationAttribute);TagsToAttributes.Add(CC_GameplayTags::Attributes_Secondary_BlockChance, GetBlockChanceAttribute);TagsToAttributes.Add(CC_GameplayTags::Attributes_Secondary_CriticalHitChance, GetCriticalHitChanceAttribute);TagsToAttributes.Add(CC_GameplayTags::Attributes_Secondary_CriticalHitDamage, GetCriticalHitDamageAttribute);TagsToAttributes.Add(CC_GameplayTags::Attributes_Secondary_CriticalHitResistance, GetCriticalHitResistanceAttribute);TagsToAttributes.Add(CC_GameplayTags::Attributes_Secondary_HealthRegeneration, GetHealthRegenerationAttribute);TagsToAttributes.Add(CC_GameplayTags::Attributes_Secondary_ManaRegeneration, GetManaRegenerationAttribute);TagsToAttributes.Add(CC_GameplayTags::Attributes_Secondary_MaxHealth, GetMaxHealthAttribute);TagsToAttributes.Add(CC_GameplayTags::Attributes_Secondary_MaxMana, GetMaxManaAttribute);}

3.在CC_AttributeMenuWidgetController.cpp的BroadcastInitialValues方法里:

void UCC_AttributeMenuWidgetController::BroadcastInitialValues()
{if (CC_AttributeSet == nullptr){CC_AttributeSet = CastChecked<UCC_AttributeSet>(AttributeSet);}checkf(AttributeInfo, TEXT("在[%s]中没有配置AttributeInfo"), *GetNameSafe(this));for (auto& Pair : CC_AttributeSet->TagsToAttributes){FAttributeInfo Info = AttributeInfo->FindAttributeInfoFromTag(Pair.Key);Info.AttributeValue = Pair.Value().GetNumericValue(CC_AttributeSet);OnAttributeInfoSignature.Broadcast(Info);}
}

这段代码实现了虚幻引擎5 GAS中属性菜单小部件控制器的初始值广播功能。

首先检查属性集是否为空，如果为空则通过类型转换获取属性集实例。接着验证AttributeInfo数据资产是否有效，如果未配置则会触发断言错误。

核心逻辑是遍历属性集中的TagsToAttributes映射，为每个属性标签查找对应的属性信息配置。通过GetNumericValue方法获取属性集的当前数值，并将其设置到属性信息结构中。最后通过OnAttributeInfoSignature委托广播更新后的属性信息，通知UI组件进行相应更新。

该函数通常在WidgetController初始化时调用，确保UI能够正确显示所有属性的初始数值。

效果:
