Introduction

Nowadays libraries such as Spigot, Bukkit and so on, gave lots of useful APIs in order to code Minecraft server plugins. However there are lots of missing functions and methods that would make a plugin development easier. In order to accomplish that, we have created a collection of useful functions to use side by side with a Minecraft server library.

Requirements

• Spigot or Bukkit
• Minecraft 1.8.*
• JAVA 8

API

Generic

Setup Minigame

In order to use this minigame API first you have to register your minigame. You need to have a folder where you keep all the sample worlds for being loaded on the fly.

GameController gameController = GameAPI.getInstance().registerGame(plugin, worldsFolder);

this will return a game controller which will have all the methods needed to run the minigame. After registering it you can create your arenas

ArenaSolo arenaSolo = (ArenaSolo) gameController.createArena(ArenaType.SOLO);
ArenaTeam arenaTeam = (ArenaTeam) gameController.createArena(ArenaType.TEAM);

Now you should initialize the locations of the arena. We have created an example file of the locations.

GameSession gameSession = new GameSession(arena, minPlayers, maxPlayers); // You should create a game session per round
arena.initialize(...);
session.update(GameState.LOBBY, maximumTime);

We have also added the possibility to set the arena flags!

arena.updateFlag(ArenaFlag.BLOCK_BREAK, false); // False means can't break blocks, true would mean the opposite
arena.updateFlag(Arena.HUNGER, true);
arena.updateFlag(...);

Thats it, now you just have to register the custom events you need such as join arena, leave arena, cross border, timer tick, timer expire, etc...

Setup Database

Those who want more complex minigames can use databases also included here.

// Database Types - MYSQL, ORACLE, POSTGRE
Database database = Database.createDatabase(DatabaseType.MYSQL, hostname, port, database, username, password);

Now you have got a database so lets connect to it!

database.connect();

Do you want to query the database? That is as simple as this

String query = "SELECT * FROM Players WHERE Players.UUID = ?"; // Runs on prepared statements
List<Object> parameters = new ArrayList();
parameters.add(player.getUuid());

ResultSet result = database.executeQuery(query, parameters);
while(result.next()) {
    (...)
}

Also insert updates?

String update = "INSERT INTO Players(UUID, Name) VALUES (?, ?)";
List<Object> parameters = new ArrayList();
parameters.add(player.getUuid()); // Parameters must be sorted accordingly with the statement
parameters.add(player.getName());

int numRowsUpdated = database.executeUpdate(update, parameters);

Scoreboard

You can create custom and epic scoreboards in only 10 seconds (the time you take to copy and paste this code).

// InfoBoard is the custom class for scoreboard
double updateInterval = 5; // Update interval (in ticks) of the scoreboard dynamic labels (eg. ScrollingLabel). Negative value to disable this automatic update.
InfoBoard infoBoard = new InfoBoard(updateInterval);

// Title
infoBoard.setTitle(new ScrollingLabel(new ColorScroller("MINI GAME", 1, ChatColor.AQUA, ChatColor.YELLOW, ChatColor.GOLD))); // Color scroller on the title

// Body
infoBoard.addLabel(new BlankLabel(5)); // 5 is the position on the scoreboard
infoBoard.addLabel("vip", new ScrollingLabel(new TextScroller("§fBecome §6VIP §fat our store! | ", 15, 4)); // 15 is the length of the scroller text. "vip" is the ID of the label
infoBoard.addLabel(new BlankLabel(3));

// Footer
infoBoard.addLabel(new StaticLabel("separator", "§8---------------", 2);
infoBoard.addLabel(new StaticLabel("", "§fCheck us out", 1)); // You can use empty strings for ID
infoBoard.addLabel(new StaticLabel("website", "§6www.mywebsite.com")), 0;

// Send to a player
infoBoard.send(player);

Well there you go! You have a gorgeous scoreboard with no effort at all!
