UDP TCP Socket Server. Easy to use TCP and UDP Sockets in Blueprints.

  • Supported Target Platforms
  • Supported Engine Versions


You can easily use TCP and UDP connections to send and receive data in blueprints with this plugin . This is a Server. You can buy a client here. Since this is a server, it is important to open the ports in your firewall and router. Use UDP for streams, gaming (your own replication). For everything else, like matchmaking, lobby, chat, is TCP suitable. I recommend my JSON plugin for data communication. Multiple servers on multiple different ports simultaneously are not possible. You don't need C++. I only tried Windows, Linux and Android. But the plugin should run on any platform where the engine is running. (I do not have an IOS device and cannot help.)

I recommend this tool for testing and developing.

Testproject 4.17, 4.18, 4.19

I have now a Mac and an iPhone 5 and I will test IOS myself. I recommend that IOS users wait with the purchase until all tests are finished.
