Unreal Engine 5 Documentation has been moved to the Epic Developer Community

With the Remote Control C++ API, you can access different parts of the Remote Control Plugin. You can build custom integration and Remote Control adapters with Unreal Engine, and use custom transports to access the Remote Control entities.

This page introduces the Remote Control C++ API, with links to the Unreal Engine C++ API Reference for further details.

Workflow

1. Set up a server in your Unreal Engine Project to send and receive data between Unreal Engine and your C++ application. For example, you can use FUdpSocketBuilder and FIPv4Endpoint .

2. Create an external C++ application to send and receive data from the server in your Unreal Engine project.

3. Create a parser and manager in your Unreal Engine Project to process received data and call Remote Control functions.

API

The following classes make up the core functionality of the Remote Control C++ API:

• IRemoteControlModule : Access functionality available at the Module scope, such as getting and resolving Remote Control Presets.

• URemoteControlPreset: Includes access to:

  • Targets that contain exposed functions, properties, and Actors.

  • Getters that use unique IDs and labels for exposed entities such as property, function, and Actor so you can access the entity from Editor, Game Mode, Simulation, and Package.

  • A listener for property changes.

  • Delegates when an entity is exposed or unexposed.

• FRemoteControlEntity: Access to exposed objects, properties, functions, and Actors, and their metadata

• FRemoteControlProperty: Represents a property exposed to Remote Control, and includes access to FProperty and RemoteControlPropertyHandle for getting and setting values of the exposed property

• FRemoteControlFunction: Access to the UFunction pointer and function argument so you can invoke the function on a specific object using UObject->ProcessEvent(UFunction*, ArgumentsMemory)

• FRemoteControlActor: Access to the pointer for an exposed Actor.

• IRemoteControlPropertyHandle: Access to getters and setters to modify the values of exposed properties, and access child properties for complex types.

• Module:DisplayClusterRemoteControlInterceptorDisplayClusterRemoteControlInterceptor: Use this to set any property values replicable through nDisplay.
