How to send a Pixel Streaming Response

The Pixel Streaming Plugin that runs within the Unreal Engine exposes a Blueprint API that you can use in your gameplay logic to handle custom UI events sent by the player HTML page and to emit events from the Unreal Engine to the player page.

To access this Blueprint API, add the Pixel Streamer Input to the Player Controller of your project with Pixel Streaming Plugin enabled for your project.

Image 1. Add the Pixel Streamer Input: Pixel Streaming Plugin

BP_DemoDisplay Blueprint:Path: Content\DemoRoom\BluePrint

You can retrieve it from the Player Controller using the Actor > Get Component by Class node. Click the Component Class input, and look for the PixelStreamingInputComponent in the list.

Pixel Streaming Response String is a public variable which will be set for each instance of the BP_DemoDisplay differently in the map for the demonstration purpose.

In the demo Send Pixel Streaming Response function is attached to the 3d Button press in map, however this can also be attached to any Key Press, other Custom Events and UMG events.
