Using the Plugin with C++

After enabling the plugin, you need to use the UDolbyIOSubsystem class to be able to use the available features in C++. We will show an example using Unreal Engine 5's First Person C++ game template. For simplicity, we assume that the project is named "Foo".

1. Add DolbyIO module​

Open Foo/Source/Foo/Foo.build.cs and add "DolbyIO" in PublicDependencyModuleNames:

PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "DolbyIO", "Engine", "InputCore", "HeadMountedDisplay" });

2. Edit FooCharacter.h​

Open Foo/Source/Foo/FooCharacter.h and add these lines somewhere in the AFooCharacter class:

UFUNCTION()
void OnDolbyIOInitialized();

class UDolbyIOSubsystem* DolbyIOSubsystem;

3. Edit FooCharacter.cpp​

Open Foo/Source/Foo/FooCharacter.cpp and replace the BeginPlay function definition with:

#include "DolbyIO.h"

void AFooCharacter::BeginPlay()
{
    // Call the base class  
    Super::BeginPlay();

    if (UGameInstance* GameInstance = GetGameInstance())
    {
        DolbyIOSubsystem = GameInstance->GetSubsystem<UDolbyIOSubsystem>();
        if (DolbyIOSubsystem)
        {
            DolbyIOSubsystem->OnInitialized.AddDynamic(this, &AFooCharacter::OnDolbyIOInitialized);
            DolbyIOSubsystem->SetToken("paste token here");
        }
    }
}

void AFooCharacter::OnDolbyIOInitialized()
{
    if (DolbyIOSubsystem)
    {
        DolbyIOSubsystem->DemoConference();
    }
}

4. Configure access credentials​

Provide your client access token in the DolbyIOSubsystem->SetToken... line.

5. Compile and run​

You should connect to the demo conference when the game starts.
