UE5.2 status: Available but not yet tested in detail.


Please check the documentation for up-to-date examples of the functions.  


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. All functions can be used independently in almost all Blueprints. You can start the server in Blueprint A. You can receive the data Blueprint B and C. Then you can stop the server in Blueprint X. 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. You don't need C++. You can use this tool for testing and developing. Nativizing may not be possible in the blueprints where the plugin is used. See Documentaiton.

My prices are low all year round. 

Version 1.12 and 1.20 tested on: Windows 10, Mojave, Android 7 and 9, IOS 12.

Free Win64 Demo with GUI (100MB)

Demo Projects v1.12 for 4.21 , v1.20 for 4.22, v1.30 for 4.25, v1.40 4.26 and newer (Plugin needed, GUI Elments are so big because of mobile), C++ Demo

Demo that shows how to find a server on the LAN. Win64, Project (Server and Client Plugins needed), Screenshots, Video


Changelog (4.27, 5.00, 5.10)

  • (01/03/2022) Version 1.50: Memory management revised to avoid memory leaks. You don't have to connect a target in Blueprints anymore (except for the events). Minor bug fixes. 


Changelog (4.26, 4.27, 5.00)

  • (09/26/2022) Version 1.44: Bugfix: Cross compiling should work now.
  • (09/02/2022) Version 1.43: Bugfix: Plugin could not be compiled on Linux.
  • (07/19/2022) Version 1.42: Bugfix: Plugin was not able to compile in C++ projects.
  • (04/22/2022) Version 1.41: You can now pass the RCON password as a parameter instead of loading it from a file.
  • (04/18/2022) Version 1.40: RCON protocol implemented. You can create an RCON server that communicates with third party RCON clients. 


Changelog (4.25, 4.26, 4.27)

  • (12/07/2021) Version 1.31: Added function to start the UE4 game server (game host) at runtime. Added various integer and float to bytes and back functions.
  • (02/14/2022) Version 1.32: See version 1.23. Additionally added a better function. See documentation. 
  • (10/17/2021) Version 1.30: IPv6. AES encryption/decryption. File sending and receiving over TCP (without RAM consumption).


Changelog (4.23, 4.24, 4.25)

  • (07/16/2020) Version 1.23: If you send small messages very quickly over TCP, they are sometimes merged , or if you send large messages, they are split. This problem can now be solved with the node "TCPMessage Wrapping


Changelog (4.22, 4.23, 4.24)

  • (04/30/2020) Version 1.21: UDP packet size can be determined.
