For the third London is Unreal meetup I made a presentation on the topic of plugins and chose to implement a useful plugin live during the presentation. A socket.io client was chosen as the plugin, which was finished with a basic Connect, Bind, Emit functions and an On event all interfaced through an Actor Component. Doing this in a small time frame was a daunting task, but something I was certain was doable. While I didn’t meet my target of 15min for the live implementation, within 25minutes the whole meetup was chatting away from their phones with a UMG chat widget in the game engine.
The presentation slides can be found here.
How does this look like in blueprints?
After adding the new plugin component to your actor of choice
You connect and bind functions of choice
which you can receive as events
and emit equally easily
A C++ version of this setup is available and I encourage you to check out the main forum thread and github repository for more details.
