Unity Drones Multiplayer

A sample project to use UNET protocol between client and server to allow multiplayer support for Unity by enabling multiple users to connect and control a drone while watching other players interact with their own drones.

Execution on Windows

• Open main folder in Unity, open File > Build Settings.
• Build Scenes/desert into ./Build/Desert/start.exe.
• Build Scenes/server into ./Build/Server/start.exe.
• Run Server/start.exe
• Run Desert/start.exe multiple times
• Connect with a different username on each desert window
• Interact in one window to watch the drone fly in the others as well

You can also execute the server by opening Scenes/server in unity and pressing Play.

Building and Running with Docker

• Open main folder in Unity, open File > Build Settings.
• Build Scenes/desert into ./Build/Desert/start.exe.
• Run Desert/start.exe multiple times

To build the server

• Open main folder in Unity, open File > Build Settings.
• Change build settings to Linux + x86 + x86_x64 (Universal) + Headless Mode: true.
• Open Player Settings and set Scripting Define Symbols to CROSS_PLATFORM_INPUT;DEDICATED_SERVER_MODE.
• Build Scenes/server into ./Build/Server/Linux/linuxserver.x86.
• Build and Run with docker (from root folder):

docker build -t unitydronesserver:latest .
docker run -p 5701:5701/udp unitydronesserver:latest

• Check that the docker container is running:

docker ps -a

• Start multiple clients and connect

Run on Kubernetes on Azure

You can run Building and Running with Docker to create a new image, then run the following commands: (Replace <USER_NAME> with your docker hub user name)

docker tag unitydronesserver:latest <USER_NAME>/unitydronesserver:latest
docker push <USER_NAME>/unitydronesserver:latest

Follow instructions to setup a new kubernetes cluster on Azure under: k8s/setup.sh.

Deploy a new application using:

kubectl create -f k8s/app.yaml

If you want to use your own image, change k8s/app.yaml and replace morshemesh with your own user name.

• Wait until the Service is done deploying on kubernetes and has a Public IP
• Use that Public IP and set server_ip under Assets/Scripts/Client.cs.
• Build/Run the client for Windows.
