You could have both projects just set a data structure somewhere on the web and have the other retrieve it. like a JSon file or something similar.
I was following Rama’s UDP connectivity tutorial (A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums), but with the distinction being that the communicating instances are from different projects, both have identical TransfarableData structures, and so far I’ve only set the IP addresses to local. The instances don’t seem to be able to communicate. I did a similar experiment a while ago with both instances being from the same project and it worked. So I’m wondering if they really have to be from the same project, or am I doing something else wrong. Thanks.
Thanks for the answer, but I’m curious as to why doing it the way Rama’s tutorial did wouldn’t work if the different projects aren’t an issue.
I’d also like to mention that it will have to work over a LAN network, disconnected from the world wide web.
Turns out I messed up in a portion of code. It works just fine with different project builds.
