This is the code

private static Main instance;

public void onEnable()
{
instance = this;

PluginManager pm = Bukkit.getServer().getPluginManager();
pm.registerEvents(new InventoryClickEvent(), instance);
pm.registerEvents(new PlayerJoinEvent(), instance);

public static Main getInstance()

}

private void registerCommands()

}

 

It seems like you have imported the events and not the classes.

_zircon_.

 

1.: Why is the instance static?
2.: Why do you have an onDisable, if you don't use it?
3.: The method registerEvents(Listener, Plugin) in the type PluginManager is not applicable for the arguments (InventoryClickEvent, Main)
InventoryClickEvent either
a) Doesn't extend Listener
b) You imported the wrong class, never name your classes the same as bukkit classes

 

For your point 3: They are not the wrong way round, it is looking for an event and not a listener class.

 

I already changed it before you commented

 

Mmk...

 

What lines are you referring to?

 

1. He is referring to the only static field.
2. He is referring to the only onDisable
3. He is referring to when you are registering your "events". The input is a listener, not the event instance. Replace those three lines with registerEvents(Listener class , this);

A) Refers to number 4. The class you are registering must implement listener
B) You imported the wrong class. As he said, the names of each of your classes must be unique.

 

@MCBro911

1. private static Main instance;

2. public void onDisable() {}

3. public class Main extends JavaPlugin {

Code:

pm.registerEvents(new InventoryClickEvent(), instance);
pm.registerEvents(new PlayerJoinEvent(), instance);
pm.registerEvents(new PlayerChatEvent(), instance);
import org.bukkit.event.inventory.InventoryClickEvent;
import org.bukkit.event.player.PlayerChatEvent;
import org.bukkit.event.player.PlayerJoinEvent;

That is what @mcdorli refers to

EDIT: Ninja'ed by @Zombie_Striker

 

It's not a good idea to name your "main" class Main. Also why don't you create the instance in your listeners class? Like

Code:

Main plugin;

public listenerclassname (Main plugin) { this.plugin = plugin; }

also I think you have to register your classes like this

Code:

Bukkit.getPluginManager().registerEvents(new listenerclassname(this), this); 

 

All I wanted to do was update my 1.7 plugin to 1.9.

How would I exactly do that? Those codes used to work back in 1.7

 

Your problem is that you are trying to register the events instead of the class that has those commands. This should never have worked in any update.

Just register the listener (the class that extends listener) instead of the events themselves and that error should go away.

 

so
public class Main extends JavaPlugin {

?

 

@MCBro911
I really don't know what you are trying to say.

The thing is, you need to register the one that has implements Listener and has the events in it. Just register the class with the events in it.

 

When something "works" that doesn't mean it is OK to have it like that. With this code, you can't be considered a java developer.
