A port of GGPO to an Unreal Engine 4 plugin. This was branched from BwdYeti's great initial work on this repo here.
Add to the Plugins folder of your Unreal project.
See doc/README.md, doc/DeveloperGuide.md, and the GGPO GitHub for more information.
Use branched repo of BwdYeti's VectorWar UE4 which is a port of the GGPO sample game VectorWar, using GGPOUE4 for netcode.
Currently the Connection Manager abstraction interface only has ip based connections implimented which only work on windows. Adding support for Steam and Epic network communication libraries is completely possible with this codebase, but requries setting up a project with those backends and testing which I do not currently have time for.
