Installation
I assume you already have got a server ready to use this plugin for. If not please look at this wiki page to learn how to setup one.
First you need to download the plugin. You can find the download link on DBO (press the download button in the top-right corner of the page) or on SpigotMC (press the download now button ion the top-right corner of the page). Once you have downloaded the plugin extract the files from ZIP file (you can use a program like WinZip or 7Zip (some OSs have this built in) to extract the files). Now find the file named buildinggame.jar (it should be the largest file) and copy, move or cut it to the /plugins/ folder inside your Minecraft server folder. Now start the server. Once it's done loading stop the server again. All files should be generated.
If you're using a BungeeCord server please follow these steps and want to connect your plugin to BungeeCord (not mandatory) follow these steps. If you're not sure whether you want to use this with BungeeCord, ignore this for now. You can always come back and hook BungeeCord up later.
Linking the plugin with BungeeCord means that you can place join signs and set the main spawn on a different server than the plugin is running. This allows you to keep all your arenas on one server and your hub / spawn on a different one.
First copy, move or cut the buildinggame-bungeecord.jar (that came included in the ZIP file) to your BungeeCord server's /plugins/ folder. Now copy, move or cut the buildinggame-addon.jar (also included in the ZIP file) to the other server where you want your main spawn to be.
Warning: Do not under any circumstances put the buildinggame-addon on the same server as the buildinggame file. If you do that the plugin will crash. If you want the main spawn to be on the same server as the arenas, you shouldn't link the plugin to BungeeCord.
Now start both the BungeeCord server and the other server and stop. Now go into your server's (not the BungeeCord one, but the other) /plugins/ folder and navigate to the newly created /BuildingGame_Addon/ folder. Open the config.yml (a decent text-editor is recommended) and go to the bungeecord > server > address key (if you're uncertain how the YAML file format works please visit this page). Now change the value to the address your BungeeCord instance is running on. Do the same for the config.yml in the /BuildingGame/ folder on your main server. Now on the main server also set bungeecord > enable to `true.
Alright the plugin is now good to go.
The main spawn is the place where all your players will go once they leave an arena or when the game is over. This position is global meaning that every arena has the same main spawn. To set a main spawn point, type the following command:
/bg setmainspawn
This will now set the main spawn at your position.
