Since the plugin is quite big, what part of it will you need?

 

@danichef The Main.class file and the BoosterCommands file

 

K, so:
Main:

Code:

public class Main extends JavaPlugin implements Listener {
  
    BoosterCommands bo = new BoosterCommands();
    public static Main plugin;
    SettingsManager settings = SettingsManager.getInstance();
    TokenRain Tk = new TokenRain();
    Lag Lg = new Lag();

  
    public void onEnable(){
        BoosterDataBase.createFile();
        registerCommands();
        settings.setup(this);
        plugin = this;
        getServer().getPluginManager().registerEvents(new AntiFallDamage(), this);
        getServer().getPluginManager().registerEvents(new BowBooster(), this);
        getServer().getPluginManager().registerEvents(new LiveBooster(), this);
        getServer().getPluginManager().registerEvents(new Blood(), this);
        getServer().getPluginManager().registerEvents(new AntiLog(), this);
        getServer().getPluginManager().registerEvents(new JoinLoc(), this);
        getServer().getPluginManager().registerEvents(new ScoreboardManager(), this);
        getServer().getPluginManager().registerEvents(new TokenRain(), this);
        getServer().getPluginManager().registerEvents(new DoubleJumpBooster(), this);
        getServer().getPluginManager().registerEvents(new PvpGrief(), this);
        this.Rain();
        this.Lag();
    }
      
  
    public void onDisable(){
        bo.onFireBow = false;
        bo.onDoubleLives = false;
        bo.onDoubleJump = false;
    }
      private void registerCommands() {
            getCommand("booster").setExecutor(new BoosterCommands());
            getCommand("setloc").setExecutor(new JoinLoc());
            getCommand("setcenter").setExecutor(new TokenRain());
      }    
    public void Rain(){
        BukkitScheduler scheduler = getServer().getScheduler();
        scheduler.scheduleSyncRepeatingTask(this, new Runnable() {
            @Override
            public void run() {
                Tk.onRandomSpawn();

        }, 0L, 3600L);
    }

        scheduler.scheduleSyncRepeatingTask(this, new Runnable() {

@danichef Wait, you're registering these as events, but they look a lot like commands. Does booster commands implement Listener? If not, then you are trying to register events that aren't events at all.

 

@danichef
Issue is pretty simple. You are not allowed to have more than one instance of your plugin (and that instance is created automatically, so you should not create any). Instead of creating a new instance of your Main class, pass the instance from your main class somehow. In this case, I'd say passing it through a constructor would be appropriate.

 

I tryed adding he schedulers as events since I thought that was the error but it didnt work before eighther

@AlvinB What do u mean by instance?

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

@danichef Also, don't use Bukkit Schedulers. Use Bukkit Runnables instead.


@AlvinB Is there a place where he is creating another instance? I can't find one.

He is creating one! in booster commands a couple lines down. There is a /Err** comment next to it

 

You can also use the getPlugin method in the JavaPlugin class, like: JavaPlugin.getPlugin(YourMainClassName.class);

 

@Horsey
No, that is way slower than it needs to be. That method should only be used by other plugins which don't control the code of the plugin.

 

@AlvinB

Thx that worked!
