Timeline の作成

このドキュメントは、ブループリントで **Timeline** ノードを作成する方法の概要です。

Timeline の作成
Blueprints C++

タイムラインを作成する

以下の手順に従って、Actor ブループリントに独自の Timeline Component を作成することができます。

  1. コンテンツ ブラウザ を開いて、[Add+] > [Blueprint Class] の順に選択し、BP_TimelineActor という名前の Actor Blueprint を新規作成します。[Pick Parent Class] ダイアログが表示されます。

  2. クラス デフォルトで、イベント グラフ を右クリックし、[Blueprint Context Menu] を表示して [Add Timeline (タイムラインを追加)] を検索して選択します。

イベントグラフに新しい Timeline ノードが表示されます。

Blueprint クラスに Timeline が追加されると、[My Blueprint] タブのリストで確認することができます。

Timeline Variables

作成された Timeline は、[My Blueprint] タブで変数として利用できるようになっています。それにより Timeline コンポーネントに参照が提供されるので、Timeline ノードを利用しなければいけない時に特に便利です。これらのノードは、再生レートなどの Timeline の一定の機能へアクセスするために存在します。

たとえば、 Get Timeline 0 変数を使って、そのタイムラインの現在の Play Rate 値をクエリします。

これらの様々なノードを使って、値をクエリし Timeline ノードの動作を制御することができます。利用可能な Timeline ノードおよびその機能の一覧は、「Timeline ノード」をご覧ください。

Timeline イベントを作成する

Timeline イベント は、Timeline Component にイベントを処理する機能を提供します。以下の手順は、独自のイベントを追加する方法の例です。

  1. BP_TimelineActor を開いて、Begin Play の 実行ピン を引き出して、Add Timeline を検索して選択します。

  4. [Compile (コンパイル)] と [Save (保存)] ボタンを順にクリックします。

  5. ブループリント エディタ を閉じて、コンテンツ ブラウザ に移動します。BP_TimelineActor を見つけて レベル へドラッグします。

  6. [Play (プレイ)] ボタンをクリックして結果を確認します。

    デフォルトのタイムライン 長 である 5 秒後に、テキスト "Timeline Finished" がビューポートの左上隅に表示されます。

タイムラインの名前を変更する

ブループリントで複数のタイムラインを使用する場合は、それぞれのタイムラインに適切な名前を付けることが重要です。すべてのタイムラインはデフォルトでは、 "Timeline_n" (n は連番) という名前になります。タイムラインの名前変更は、[Graph] タブまたは [My Blueprint] タブ内でタイムラインを右クリックするか、[Rename (名前を変更)] を選択します。

Opening the Timeline Editor

タイムラインの作成は、何かパフォーマンスで設定しないと意味がないかもしれません。詳細は「タイムラインの編集ページ」を参照してください。

Creating Timelines

You can create and instantiate your own Timeline Component in an Actor class by following the steps below.

  1. Navigate to your C++ Classes folder and click the Add+. From the drop down menu select New C++ Class.

  2. Select Actor class as a Parent Class.

    Click for full view.

  3. Name created Actor class Timeline Actor.

    Click for full view.

  4. Navigate to your TimelineActor.h file and include following TimelineComponent class library.

    TimelineActor.h

        #include "Components/TimelineComponent.h"

  5. Implement the following class declaration inside the TimelineActor class defintion:

    TimelineActor.h

        protected:

        UPROPERTY(EditAnywhere, BlueprintReadWrite)
        UTimelineComponent* ExampleTimelineComp;

    In this code sample, you use the Property Specifier Tags, EditAnywhere, and BlueprintReadWrite.

  6. Navigate to the TimelineActor.cpp file, then add the following code to your TimelineActor constructor ATimelineActor::ATimelineActor()

    TimelineActor.cpp

         ATimelineActor::ATimelineActor()
     {
         // Set this actor to call Tick() every frame.  You can turn this off to improve performance if you don't need it.
         PrimaryActorTick.bCanEverTick = true;
         ExampleTimelineComp = CreateDefaultSubobject<UTimelineComponent>(TEXT("TimelineComponent"));
     }

  7. Compile your code.

  8. Navigate to the C++ classes folder, right-click on your TimelineActor and create a Blueprint based on your TimelineActor class. Name it Bp_TimelineActor.

  9. Once you have created your TimelineActor Blueprint, you can view the Class Defaults. From the Components tab, you should see your example Timeline Component.

	{
		Super::BeginPlay();
	}

	// Called every frame
	void ATimelineActor::Tick(float DeltaTime)
	{
		Super::Tick(DeltaTime);
	}

Timeline Variables

When you create a Timeline Component in C++ using UProperty Specifiers, it will become available as a variable in your Components tab. This may be useful for designers who would like to continue to make iterations to your TimelineComponent via Blueprint Scripting.

Image above shows using the native C++ Timeline Variable to get the Current Play Rate value of the Timeline in Blueprint.

For a complete list of the available Blueprint Timeline nodes and their functionality please see the Timeline nodes page.

Creating a FTimeLineEvent

Timeline Events (FOnTimelineEvent) are Dynamic Delegates that provide functionality to a Timeline Component to handle an Event. Follow the steps below to create your own FTimeLineEvent to be bound to your Timeline Component's finished functionality.

  1. Navigate to TimelineActor.h file and declare the following code in the Class Definition:

    TimelineActor.h

         protected:

         //Delegate signature for the function which will handle our Finished event.
         FOnTimelineEvent TimelineFinishedEvent;

         UFUNCTION()
         void TimelineFinishedFunction();

  2. Navigate to TimelineActor.cpp and implement the following code:

    TimelineActor.cpp

          void ATimelineActor::TimelineFinishedFunction()
      {
         UE_LOG(LogTemp, Warning, TEXT("Finished Event Called."));
      }

  3. Navigate to ATimelineActor::BeginPlay() method, and implement the following code:

    TimelineActor.cpp

         // Called when the game starts or when spawned

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

         TimelineFinishedEvent.BindUFunction(this, FName("TimelineFinishedFunction"));
         ExampleTimelineComp->SetTimelineFinishedFunc(TimelineFinishedEvent);
         ExampleTimelineComp->PlayFromStart();
     }

    You have now successfully bound your TimelineFinished Event to your custom TimelineFinished function.

  4. Compile your code. Open Editor and navigate to the Content Browser. Find your BP_TimelineActor and drag off it into the Level.
