ZMQ for Unreal Engine 4 -- Quick & Dirty
This project was built during a rapid prototyping push, so it exists as a quick-and-dirty interface. There was no thought to efficiency or elegance. There are just pass-through functions and the minimum that is required to call every zmq function in the library.
This is not completely tested. Only the basic calls are in use.
This project and its contents are provided without warranty and support will not be provided. This project and its contents exist within the public domain. Any derivations or use cases can attribute the author and this Git repository at the discretion of their owners, but any acknowledgement is appreciated.
This Git will be maintained, albeit minimally, and others are welcome to help improve this code base.
NOTES:
The source and a pre-built version are provided. Games using the ZMQUE module will only be able to compile for Windows (or anything that can handle "Win64").
The project is for Visual Studio 2015.
I forget which ZMQ version I used. I think it's either 4.1.4 or 4.0.4 but it is very easy to replace what is there now. Also, I am using the DLL version of ZMQ. That adds extra work placing the DLL where it needs to be. I plan on changing to full-static so I will update this Git at some point--if it hasn't been done by another already.
The biggest hurdle was the fact that UE4 and ZMQ treat "short" in two different ways. As with the poll item struct, it is important that any other instances of data passing also take this difference into consideration. Make sure you are explicit about the "sizeof" the data your game passes to or gets from ZMQ.
