Getting online players always returns null

Hey!

I'm working on a project where i need to get the amount of all online players. What i'm doing is calling the getOnlinePlayers()-method and checking the length of it(.length), but it always gives me an NPE. Any ideas? It should not be null. It even returns null when there are players online, and an integer should not return null either.

 

Erm, paste the code please?

 

Sure.

Code:java

    @EventHandler
    public void onPing(ServerListPingEvent event) {
        int amp = Bukkit.getServer().getOnlinePlayers().length;
        if (amp < pl.getConfig().getInt("max-players-before-deny")) {
            event.setMotd(ChatColor.RED
                    + "The server is full.");
        }
    }

 

jimbo8 i dont think amp is returning null, i think plugin is returning null 'pl' show us ur instanceof plugin

 

Haha, I'm sorry.

When i've been messing around with my plugin, i didn't actually save it in the right server-folder. I did some more debugging and the config is the one returning null, even though it does have a value. The path is as you can see in the code and the value is "5" for testing. Also, i know that the math is wrong, but this is for testing only.

Still says that it is null, though.

 

Maybe try this:

Code:java

 
    public static int getPlayersOnline(){
        int x = 0;
        try {
            x = Bukkit.getServer().getOnlinePlayers().length;
        } catch (NullPointerException e) {
            x = 0;
        }
        return x;
    }

Did you instantiate 'pl'?

 

Yeah.

The plugin compiles, but i get a NPE when refreshing my serverlist. Gater12

Why would you catch a NullPointerException. It's impossible for one to be triggered because x is an primitive integer and can't be null.

That is not what Gater12 means by instantiating your plugin. Show us your global field and constructor, please.
