Zoidcom

If you're looking for a high-level, UDP-based networking library, then you might want to check out Zoidcom. This free software provides a range of features, including support for automatic replication of game objects and synchronization of their states over a network connection in a highly bandwidth efficient manner.

One of the key benefits of Zoidcom is its multiplexing and demultiplexing capabilities. This allows object information to be transmitted in bitstreams, which helps to reduce the amount of redundant data that needs to be sent. For example, booleans take up just one single bit, while integers and floats are stripped down to as many bits as needed.

Another advantage of Zoidcom is that it takes care of a lot of the tedious work that's typically involved in developing an efficient network protocol. This can help to speed up the development process and reduce the risk of errors.

It's worth noting that Zoidcom is free for non-commercial use. However, if you're looking to use it for commercial purposes, you'll need to contact the developers to discuss licensing options. Overall, if you're looking for a powerful, flexible networking library, Zoidcom is definitely worth considering.
