Low Entry Socket Connection
The Socket Connection plugin provides you with Blueprints to connect to and interact with socket servers.
The most important feature of this plugin is that this plugin has been designed to be used in conjunction with a server programmed in Java, like an account server or a match making server for example.
To make this possible, the network algorithm has also been programmed in a Java library, which has been made free and open source.
The Java library is available here.
PS: you can convert bytes to and from string (and more) with the LE Extended Standard Library plugin (which is free)
