关于节拍同步委托

您可以与添加到Cue的节拍同步信息的节拍速度匹配来调用任意已注册函数。
在委托中可以注册多个函数。

关于序列回调委托

您可以在添加到Cue中的序列回调标记的时机来调用任何已注册的函数。
在委托中可以注册多个函数。

在Cue中添加节拍同步信息

在Atom Craft准备添加了节拍同步信息的Cue。

: 关于节拍同步的详细信息，请参照 https://game.criware.jp/manual/adx2_tool/latest/criatom_tools_atomcraft_beatsync.html 。

在Cue中添加序列回调标记

在AtomCraft准备添加了序列回调标记的Cue。

: 关于序列的详细信息，请参照 https://game.criware.jp/manual/adx2_tool/latest/criatom_tools_atomcraft_sequence_marker.html 。

如何在蓝图中注册

您可以从AtomComponent调用每个委托。
也可以通过将任意的自定义事件绑定到每个委托来调用回调时的处理。

如何在C++代码中注册

MyActor.h

#pragma once
#include "CoreMinimal.h"
#include "GameFramework/Actor.h"
// Please include
#include "AtomComponent.h"
#include "MyActor.generated.h"
UCLASS()
class SO_PROJECTED_API AMyActor : public AActor
{
    GENERATED_BODY()
public:
    // Sets default values
    AMyActor();
protected:
    // Called when the game starts or when spawned
    virtual void BeginPlay() override;
    // Called before destroying an object

    void OnSequenceCallback(UAtomComponent* Atom, const FAtomSequenceInfo& Info);
private:
    // UAtomComponent reference
    UAtomComponent* AtomComponent{ nullptr };
};

MyActor.cpp

#include "MyActor.h"
// Sets default values
AMyActor::AMyActor()
{
    // Set this actor to call Tick() every frame.  You can turn this off to improve performance if you don't need it.
    PrimaryActorTick.bCanEverTick = false;
    PrimaryActorTick.bStartWithTickEnabled = false;
    // Create UAtomComponent reference 
    AtomComponent = NewObject<UAtomComponent>();
    AtomComponent->AddToRoot();
}
// Called when the game starts or when spawned
void AMyActor::BeginPlay()
{
    Super::BeginPlay();
    // Set beat sync call back function 
    AtomComponent->OnAtomBeatSyncCallback(this, &AMyActor::OnBeatSyncCallback);
    // Set sequence call back function 
    AtomComponent->OnAtomSequenceCallback(this, &AMyActor::OnSequenceCallback);
}
// Called before destroying an object
void MyActor::BeginDestroy()
{
    if(IsValid(AtomComponent) == true){
        AtomComponent->RemoveFromRoot();
        AtomComponent = nullptr;
    }
}
// Called at beat sync timing
void AMyActor::OnBeatSyncCallback(UAtomComponent* Atom, const FAtomBeatSyncInfo& Info)
{
    UE_LOG(LogTemp, Log, TEXT("Called AtomBeatSync Callback!"));
}
// Called at sequence timing
void AMyActor::OnSequenceCallback(UAtomComponent* Atom, const FAtomSequenceInfo& Info)
{
    UE_LOG(LogTemp, Log, TEXT("Called AtomSequence Callback!"));
}

注意: 请将UAtomComponent的指针和每个回调信息的结构体作为要注册函数的参数。
从实际的调用时间开始会有延迟，以实现线程安全。
请注意，由于委托是在主线程中执行，因此操作帧速率会受到影响。
