+# NBloodServerSupervisor
+Web API and NBlood server launcher service in .NET Core
+
+## Debug with Visual Studio
+1. Publish `WebInterface` to a folder with Debug configuration
+2. Create a new folder in the publish folder and name it `blood`
+3. Compile NBlood with `make nblood NORENDER=1` or with `mingw32-make nblood NORENDER=1`
+4. Copy nblood.exe into the new `blood` folder and rename it to `nblood_server.exe`
+5. Copy the following files of Blood 1.21 into the `blood` folder:
+- BLOOD.INI
+- BLOOD.RFF
+- GUI.RFF
+- SOUNDS.RFF
+- SURFACE.DAT
+- TILES000.ART-TILES017.ART
+- VOXEL.DAT
+6. Start WebInterface.exe
+7. Attach the debugger to WebInterface.exe and/or Supervisor.exe
+8. You can call the following URLs with your web browser or Postman:
+- http://localhost:5000/nblood/api/listservers
+- http://localhost:5000/nblood/api/startserver?players=3&ApiKey=CHANGEME
+
+## Deploy the server onto GNU/Linux
+1. Install Docker and wget (if you don't have already), for example like this: `sudo snap install docker && sudo apt install wget -y`
+2. Download the Dockerfile: `wget https://github.com/CommonLoon102/NBloodServerSupervisor/blob/master/Dockerfile --directory-prefix=supervisor`
+3. Switch to the new `supervisor` directory: `cd supervisor`
+4. Build the Docker image: `sudo docker build -t nblood-supervisor:latest .`
+5. Navigate to your Blood 1.21 directory where you have these files:
+- BLOOD.INI
+- BLOOD.RFF
+- GUI.RFF
+- SOUNDS.RFF
+- SURFACE.DAT
+- TILES000.ART-TILES017.ART
+- VOXEL.DAT
+6. Run a Docker container from there: `sudo docker run --volume "$PWD":/supervisor/publish/blood --network=host --detach nblood-supervisor`
+7. Optional: You can see the ApiKey here:
+- `sudo docker run -it nblood-supervisor /bin/bash`
+- `cat /supervisor/publish/appsettings.json | grep 'ApiKey'`
+- `exit`
+
+## Usage
+You can list the currently running public servers via this URL:
+
+http://your.ip.goes.here:23580/nblood/api/listservers
+
+You can start new private servers via this URL:
+
+http://your.ip.goes.here:23580/nblood/api/startserver?players=3&ApiKey=the_actual_apikey_here
+
+The number of players must be at least 3 and maximum 8. The servers started with this URL won't be visible publicly via the `listservers` URL. You can see the port and the command line command to join in the response.
