A simple demo-project to show how TCP communication works on Unity environment, builded with C# and using System.Net.Sockets.
The main porpouse of this repo is to show the TCP communication on runtime, but also to provide a pretty commented and clear code so everyone else that wants to implement that kind of communication will be able without wasting a lot of time.
Remember that are many ways to say thank you.
If this repository has been helpful remember to star it and consider buying me a coffee! 😀
If you like my general work and contributions consider sponsoring me on Github.
But if you just want to donate straightforward, I also have PayPal.me.
If you only want to see the app working, just run the SimpleTCP.exe which is located on the build directory.
If you want to open the project, you will need to have Unity installed with the version 2017 or higher.
If you only want to scratch the code, either inside the unity project or simply dragging the .cs classes on your editor, you have to watch on to this classes, which are located on Assets\Scripts:
Server.csClient.cs
Note: Unity do not allow the save-use of Multi-Threading, so the application is using Co-routines instead.
The stablished communication and workflow stablished right now follows the next order:
-
Start the Server and let it waiting for client connections.
-
Start the Client and connect it to the server.
-
Server/Client waits for client/server messages...
-
Client/Server sends any type of message to the server/client.
-
Server/Client sends recives the message from the client/server.
-
Server/Client waits for new client/server messages...
-
In Case Client sends "Close" to Server
-
Client sends "Close" to Server, and waits a timeOut to disconnect from it.
-
Server recives that Close message and closes the connection with the client.
-
Server waits for new incoming client connections.
-
Server shuts down (Optional)
Keep in mind that this "Close" system is not the typical four-way handshake used in TCP, but it's builded like this to keep it simple and understandable. You can learn more about TCP Connection termination here.
