每当项目变复杂后，你会发现在场景中查找 Actor 会变得愈发困难。场景中往往可以有数以百计的Actor，包括关卡模型和几何体、NPC、敌人、可交互对象、可拾取对象等。 在虚幻编辑器中工作时，你可以使用 世界大纲 视图来定位某个Actor。
在上图中，世界大纲视图（右）展示了所有放置在关卡中的Actor。点击世界大纲视图中的一个Actor后，该Actor会在关卡视图中高亮显示。你可以点击 Actor 或 类型（Type），将Actor按照名称或类型进行排序（你可以点击类型框中的向下箭头，将二级类别从类型改为其他过滤条件）。
在世界大纲视图中选中某个Actor，然后点击关卡视图，双击该Actor或直接按下 F，可直接将窗口 对准 该Actor。
请参阅世界大纲视图了解在场景中定位Actor的方法。
项目设置
在本教程中，你将使用 Get All Actors of Class 节点在关卡中找到Actor。此节点受到调用时，它将检索关卡指定类（Class）中的所有Actor，并将它们放置在 数组（Array） 中。然后，你可以根据筛选条件从该数组中检索Actor。然后，你可以访问Actor的属性，或者根据你要实现的功能以某种方式修改它们。
-
首先，点击 新建（New） > 游戏（Games）> 第三人称（ThirdPerson） > 蓝图项目带初学者内容包（Blueprint Project With Starter Content），创建名为 FindingActors 的项目。

创建火焰Actor
初学者内容包（Starter Content） 文件夹提供了完整的FireEffect Actor，其中包括表示火焰效果的 粒子组件（Particle Component） 和用于声音效果的 音频组件（Audio Component） 。此Actor将用作从Get All Actors of Class节点查找的Actor基类。
-
找到 内容（Content） > StarterContent > 蓝图（Blueprints） ，然后将 Blueprint_Effect_Fire 实例拖到世界中。
- 点击 添加/导入（Add/Import） 按钮可以创建一个 新的C++类（New C++ Class） ，然后从 选择父类（Choose a Parent Class） 菜单中，选择 Actor ，创建名为 FireEffect** 的新Actor类。
Click for full view.
-
在FireEffect.h中，声明以下内容：
public: //获取火焰音效音频组件。 UAudioComponent* GetFireAudioComponent() const { return FireAudioComponent; } //获取火焰效果粒子系统组件。 UParticleSystemComponent* GetParticleFireComponent() const { return ParticleFireComponent; } protected: UPROPERTY(EditDefaultsOnly, BlueprintReadWrite) UParticleSystemComponent* ParticleFire; UPROPERTY(EditDefaultsOnly, BlueprintReadWrite) UAudioComponent* FireAudio; -
找到
FireEffect.cpp文件并添加以下类库：#include "Particles/ParticleSystemComponent.h" #include "Components/AudioComponent.h" -
在FireEffect构造函数中，实现以下代码：
AFireEffect::AFireEffect() { // 将此Actor设置为每帧调用更新函数()。 如果不需要此特性，可以关闭以提升性能。 PrimaryActorTick.bCanEverTick = true; ParticleFire = CreateDefaultSubobject<UParticleSystemComponent>(TEXT("P_Fire")); FireAudio = CreateDefaultSubobject<UAudioComponent>(TEXT("Fire Audio")); ParticleFire->SetupAttachment(RootComponent); FireAudio->AttachToComponent(ParticleFire,FAttachmentTransformRules::KeepRelativeTransform); } -
编译 你的代码。
-
找到 内容浏览器（Content Browser） > C++类（C++ Classes） > FindingActors，右键点击 FireEffect Actor，创建 名为 BP_FireEffect 的基于FireEffect的蓝图类。
-
在 BP_FireEffect 的 类默认值（Class Defaults） 中，点击 组件（Components） 面板中的 粒子火焰（Particle Fire） ，然后找到 细节（Details） 面板，在 粒子（Particles） 类别下，打开 模板（Template） 下拉菜单并选择 P_Fire 。
- 点击 组件（Components） 面板中的 火焰音频（Fire Audio） ，然后找到 细节（Details） 面板。从 音效（Sound） 类别打开 音效（Sound） 变量下拉菜单，然后选择 Fire01_Cue 。
- 点击 编译（Compile） 和 保存（Save） 。

点击 编译（Compile） 和 保存（Save） 。
-
在 内容浏览器（Content Browser） 中，找到 C++类（C++ Classes） > FindingActors ，双击 FindingActorsCharacter 打开
FindingActorsCharacter.h文件。
-
在 FindingActorsCharacter 类默认值中，声明以下内容：
protected: void OnFindActorPressed(); -
找到
FindingActorsCharacter.cpp，并添加以下类库:#include "Kismet/GameplayStatics.h" #include "FireEffect.h" #include "Particles/ParticleSystemComponent.h" #include "Components/AudioComponent.h"
注意：虚幻引擎将使用Include-What-You-Use（IWYU）依赖性模型。这意味着引擎的源代码只包含它需要编译的依赖性。有关更多文档，请参阅IWYU。
-
通过声明以下代码来实现 OnFindActorPressed 的逻辑：
void AFindingActorsCharacter::OnFindActorPressed() { TArray<AActor*> ActorsToFind; if(UWorld* World = GetWorld()) { UGameplayStatics::GetAllActorsOfClass(GetWorld(), AFireEffect::StaticClass(), ActorsToFind); } for (AActor* FireEffectActor: ActorsToFind) { //这是否是类型FireEffect类的Actor？ AFireEffect* FireEffectCast = Cast<AFireEffect>(FireEffectActor); if (FireEffectCast) { //获取粒子火焰组件并停用它。 FireEffectCast->GetParticleFireComponent()->Deactivate(); //获取火焰音频组件并停用它。 FireEffectCast->GetFireAudioComponent()->Deactivate(); } } } -
找到 SetupPlayerInputComponent 方法，并声明以下代码：
void AFindingActorsCharacter::SetupPlayerInputComponent(class UInputComponent* PlayerInputComponent) { PlayerInputComponent->BindAction("FindActorPressed", IE_Pressed, this, &AFindingActorsCharacter::OnFindActorPressed); } -
编译你的代码。

通过标签获取特定Actor
你使用了Get All Actors of Class节点来获取指定类的Actor数组。但是，你也可以在Actor上使用 标签（Tags） ，根据不同的条件筛选数组结果，以便从数组中获取特定的Actor或单个Actor。示例，
-
找到 内容（Content）> StarterContent > 蓝图（Blueprints） ，并选择 Blueprint_Effect_Fire 。
-
在 细节（Details） 面板中，找到 标签（Tags） 分段，然后点击 添加（Add）（+）将标签添加到Actor。
-
在 0 元素字段中，在文本字符串中输入"FindActorTag"。
-
在 MyCharacter 蓝图中，从 ForEachLoop 的 数组元素（Array Element） 引脚拖出，然后在 操作（Actions） 菜单中搜索 Get Tags 。

点击 编译（Compile） 和 保存（Save） 。
-
在 关卡视口（Level Viewport） 中选择你的 Blueprint_FireEffect 之一，然后在 细节（Details）面板 中，找到 标签（Tags） 变量，找到 FindActorTag 字段并打开下拉菜单，然后选择 删除（Delete） 删除标签变量。
为了演示功能，我们特意留下了一个没有标签的火焰效果。
-
找到 工具栏（Toolbar），按 运行（Play）（PIE） 。
你使用Gameplay静态库中的Get All Actors of Class函数来获取指定类的Actor数组。但是，你也可以在Actor上使用 标签（Tags） ，根据不同的条件筛选数组结果，以便从数组中获取特定的Actor或单个Actor。示例，
-
首先，找到 内容浏览器（Content Browser） > C++类（C++ Classes） 文件夹，然后双击 FireEffect Actor 打开其
FireEffect.cpp文件。
-
在 FireEffect构造函数中 实现以下代码
AFireEffect::AFireEffect() { Tags.Add(FName("FindActorTag")); }
注意：标签是数组，是Actor类默认值的一部分，可以用于分组和分类。
-
编译 你的代码。
-
打开 BP_FireEffect ，然后在 细节（Details） 面板中找到 Actor 类别，你会注意到你的Actor标签已创建。
-
首先，找到 **内容浏览器（Content Browser） > C++类（C++ Classes） 文件夹，然后双击 FindingActorsCharacter ，打开其
.cpp文件。
-
在 OnFindActorPressed 方法中实现以下内容：
void AFindingActorsCharacter::OnFindActorPressed() { TArray<AActor*> ActorsToFind; //获取所有具有"FindActorTag"的FireEffect类的Actor UGameplayStatics::GetAllActorsOfClassWithTag(GetWorld(), AFireEffect::StaticClass(), FName("FindActorTag"),ActorsToFind); for (AActor* FireEffectActor: ActorsToFind) { AFireEffect* FireEffectCast = Cast<AFireEffect>(FireEffectActor); if (FireEffectCast) { FireEffectCast->GetParticleFireComponent()->Deactivate(); FireEffectCast->GetFireAudioComponent()->Deactivate(); } } } -
编译 你的代码。
-
在 关卡视口（Level Viewport） 中选择你的 BP_FireEffect 实例之一，然后在 细节（Details） 面板中找到 标签（Tags） 变量，找到 FindActorTag 字段，打开旁边的下拉菜单删除变量。
-
找到 工具栏（Toolbar） ，按 运行（Play）（PIE） 。
最终效果
当按下数字1键时，你应该注意到，所有带有ActorsToFindTag的Bluprint_Fire_ Effect粒子均熄灭，而没有标签的火焰效果仍然存在。
