OnJoinEvent

Did you create an instance of this class and register it?

Also, what's even the purpose of this?

Code (Text):

public static Hello plugin;

 

Are you registering the event?

 

Are you registering the event in the onEnable() (Main Class)

 

do you get any errors?

Code (Text):

event.setJoinMessage(getConfig().getString("MOTD"));

that should produce an error, because there is no plugin that it is referencing.

 

Try reading/watching the tutorial again.

 

Bukkit.getPlugin("PluginName").getConfig()...

For permissions:
event.getPlayer().hasPermission(...)

 

In onEnable:

Code (Text):

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

getConfig:

Code (Text):

Bukkit.getPluginManager().getPlugin("PluginName").getConfig()

 

Yah, the fact that it took 10 posts to get you to say there was an error is making this pretty difficult. You need to share as much information as possible as to WHY it won't work. I am not a compiler, its tough to just stare at code without errors and figure out the errors in syntax in every line.

You need to initilize this listener in your Main class.

So in the onEnable() method in your main class you should have

Code (Text):

getServer().getPluginManager().registerEvents(new MyPlayerListener(), this);

You can also save yourself some trouble by adding this method in your Main class

Code (Text):

//at the top
private Hello plugin;  

//somewhere in your main class

public static Hello getPlugin() {

        return plugin;

    }

then to get what you want in your listener

Code (Text):

public class MyPlayerListener implements Listener {
 
    @EventHandler
    public void onPlayerJoin(PlayerJoinEvent event){
        Player player = event.getPlayer();
        String motd = Hello.getPlugin().getConfig().getString("MOTD"));
       
       //notice I am sending the message, not setting the join message
        player.sendMessage(motd);
    }

}

 

Can you post your main class and your listener class? can you tell me what line 14 is in 'MyPlayerListener'? My guess is it is the Hello.getPlugin() method.

EDIT::

This is my fault, in your main class, in the onEnable() method you need to add

Code (Text):

plugin = this;

apologies. That should fix the issue

 

You should definitely look through the code, and figure out what your version didn't work, and why this one did. To learn, instead of blindly copying. A lot of the stuff here is covered in many beginner tutorials, so you should have consulted other sources and tried to understand. But, I have no problem helping either way.
