Blueprints

C++

创建时间轴

可按照以下步骤在 Actor 蓝图中创建你自己的 时间轴组件（Timeline Component）。

从 内容浏览器 中选择 添加+（Add+） > 蓝图类（Blueprint Class），创建名为 BP_TimelineActor 的新Actor蓝图。将显示 选取父类（Pick Parent Class） 对话框。
在 类默认 设置中，右键点击 事件图表（Event Graph），在 蓝图快捷菜单（Blueprint Context Menu） 中搜索并选择 添加时间轴（Add Timeline）。

新的时间轴节点将添加到事件图表中。

将时间轴添加到蓝图类之后，它将列示在 我的蓝图（My Blueprint） 选项卡中。

时间轴变量

创建时间轴后，你会发现它变成了 我的蓝图（My Blueprint） 选项卡中的可用变量。这是为了实现对时间轴组件的引用，在必须使用时间轴节点的时候，此法尤为有用。这些节点的存在是为了能够访问某时间轴的特定功能，例如其播放速率。

例如，你可以使用 Get Timeline 0 变量查询该时间轴的当前播放速率（Play Rate）值。

此类节点有很多，可用于查询各个值和控制时间轴节点的行为。如需可用Timeline节点的完整列表及其功能详情，请参阅时间轴节点。

创建时间轴事件

时间轴事件为时间轴组件提供处理自定义事件或函数的功能。按照下列示例步骤操作，了解如何实现你自己的事件。

打开 BP_TimelineActor，然后选中并拖移 开始播放（Begin play） 的 执行引脚，将其连接到你的时间轴组件的 播放（Play） 执行引脚。

点击 编译（Compile） 和 保存（Save） 按钮。
关闭 蓝图编辑器，找到 内容浏览器。找到你的 BP_TimelineActor 并将其拖放到关卡中。
点击 运行（Play） 按钮查看结果。

在5秒的默认时间轴长度之后，"时间轴结束（Timeline Finished）"字样将显示在视口左上角。

重命名时间轴

若在蓝图中使用多个时间轴，务必相应地命名各个时间轴。所有时间轴的默认名称为"Timeline_n"，其中 n 是末尾的序列号。要重命名某个时间轴，你可以右键点击 图标（Graph） 选项卡或 我的蓝图（My Blueprint） 选项卡中的该时间轴，然后选择 重命名（Rename）。

打开时间轴编辑器

有待执行的任务时才需要创建时间轴。欲详细了解如何编辑时间轴，请参阅时间轴编辑页面。

创建时间轴

可按照以下步骤在 Actor 类中创建并实例化你自己的 时间轴组件（Timeline Component） 。

找到你的 C++ 类文件夹 ，并点击 添加（Add+） 。从下拉菜单中选择 新建C++类（New C++ Class） 。
选择 Actor 类作为 父类（Parent Class） 。

点击查看大图。
将创建的Actor类命名为 Timeline Actor 。

点击查看大图。
找到 TimelineActor.h 文件并包含以下 TimelineComponent 类库。

TimelineActor.h
```
    #include "Components/TimelineComponent.h"
```
#include "Components/TimelineComponent.h"
在TimelineActor类定义中实现以下类声明：

TimelineActor.h
```
    protected:

        UPROPERTY(EditAnywhere, BlueprintReadWrite)
        UTimelineComponent* ExampleTimelineComp;
```
protected: UPROPERTY(EditAnywhere, BlueprintReadWrite) UTimelineComponent* ExampleTimelineComp;
在此代码示例中，你使用属性说明符标签 EditAnywhere 和 BlueprintReadWrite 。
找到 TimelineActor.cpp 文件，然后将以下代码添加到你的TimelineActor构造函数 ATimelineActor::ATimelineActor()

TimelineActor.cpp
```
     ATimelineActor::ATimelineActor()
     {
         // 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;
         ExampleTimelineComp = CreateDefaultSubobject<UTimelineComponent>(TEXT("TimelineComponent"));
     }
```
ATimelineActor::ATimelineActor() { // 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; ExampleTimelineComp = CreateDefaultSubobject<UTimelineComponent>(TEXT("TimelineComponent")); }
编译（Compile） 你的代码。
找到 C++类文件夹 ，右键点击你的 TimelineActor ，并基于你的TimelineActor类创建蓝图。将其命名为 Bp_TimelineActor 。
创建TimelineActor蓝图后，你可以查看 类默认值（Class Defaults） 。从 组件（Components） 选项卡中，应可看到你的时间轴组件示例。

	{
		Super::BeginPlay();
	}

	// 每一帧都调用
	void ATimelineActor::Tick(float DeltaTime)
	{
		Super::Tick(DeltaTime);
	}

时间轴变量

当你在C++中使用 UProperty说明符 创建时间轴组件后，该组件会成为 组件（Components） 选项卡中的可用变量。对于想要继续通过蓝图脚本对时间轴组件进行迭代的设计人员来说，这个变量很有用。

上图显示了使用原生C++时间轴变量获取蓝图中时间轴的当前播放速率（Current Play Rate）值。

如需可用蓝图时间轴节点的完整列表及其功能详情，请参阅时间轴节点页面。

创建FTimeLineEvent

时间轴事件（ FOnTimelineEvent ）是动态委托，可为时间轴组件提供处理事件的能力。按以下步骤创建你自己的 FTimeLineEvent ，并将其绑定到你的时间轴组件的已完成功能。

找到 TimelineActor.h 文件并在 类定义 中声明以下代码：

TimelineActor.h
```
     protected:

         //委托将处理已完成事件的函数的签名。
         FOnTimelineEvent TimelineFinishedEvent;

         UFUNCTION()
         void TimelineFinishedFunction();
```
protected: //委托将处理已完成事件的函数的签名。 FOnTimelineEvent TimelineFinishedEvent; UFUNCTION() void TimelineFinishedFunction();
找到 TimelineActor.cpp ，并实现以下代码：

TimelineActor.cpp
```
      void ATimelineActor::TimelineFinishedFunction()
      {
         UE_LOG(LogTemp, Warning, TEXT("Finished Event Called."));
      }
```
void ATimelineActor::TimelineFinishedFunction() { UE_LOG(LogTemp, Warning, TEXT("Finished Event Called.")); }
找到 ATimelineActor::BeginPlay() 方法，并实现以下代码：

TimelineActor.cpp
```
     // 当游戏开始或重生（Spawn）时调用

     void ATimelineActor::BeginPlay()
     {
         Super::BeginPlay();

         TimelineFinishedEvent.BindUFunction(this, FName("TimelineFinishedFunction"));
         ExampleTimelineComp->SetTimelineFinishedFunc(TimelineFinishedEvent);
         ExampleTimelineComp->PlayFromStart();
     }
```
// 当游戏开始或重生（Spawn）时调用 void ATimelineActor::BeginPlay() { Super::BeginPlay(); TimelineFinishedEvent.BindUFunction(this, FName("TimelineFinishedFunction")); ExampleTimelineComp->SetTimelineFinishedFunc(TimelineFinishedEvent); ExampleTimelineComp->PlayFromStart(); }
现在你已成功将 TimelineFinished 事件绑定到自定义 TimelineFinished 函数。
编译你的代码。打开 编辑器（Editor） 并找到 内容浏览器（Content Browser） 。找到你的 BP_TimelineActor 并拖移到 关卡（Level） 中。
按 播放（Play） 按钮。在 输出日志（Output Log） 窗口中应该可以看到以下消息：
