Declaring plugin -- always is null?

I need to fetch some config values in a class other than the main one, so I need to do something along the lines of

Code:

plugin.getConfig().getWhatever("Something", Something)

However, whenever I declare the

Code:

public static pluginname plugin;

I get nullpointer exceptions. Please help.

 

Did you declare it in the main class?

 

Code:

public static pluginname plugin;
 
 
@Override
public void onEnable() {
plugin = this;
}

When you don't set the "pluginname" to anything except a name -> plugin, then it will be null.

When you declare any instance variable they will always have a default value, unless you assign the instance variable with a value the default value will remain.

Also, avoid making any variable static. It is not necessary.

 

Or can do it how I do it..declare the variables globally in the main...

Code:java

 
public class Main extends JavaPlugin implements Runnable {
 private static Main instance;
 public final Main playerListener = this;
 Lis lis = new Lis(playerListener);
 Logger log = Logger.getLogger("Minecraft");
 static List<String> msgs;
 static int msgCount = 0;
 static int currentMsg = 0;
 static int BreedChance = 0;
 

then load it as normal in the main onenable by reading the config.

and call it in any class by doing Main.BreedChance or Main.msgCount etc..
if you Main is called BobsAwesomeMainClass it would be BobsAwesomeMainClass.BreedChance

 

I have a sample plugin here that dispenses with the static instance field. https://github.com/SagaciousZed/SampleBukkitPlugin/tree/master/src/main/java/com/example/groupid

 

True much simpler, if I could figure out the right way to have multiple listener classes, and classes to put random one shot methods in and call them correctly, Id use that

My Main, and Lis classes have ALL kind random methods in them not related to what they 'do' as far as class organization. because not sure how to move a method to say "conLoad.class" to call it and read the config, using it.

I Guess my way I showed isn't really the best way, its more a "Not sure how to do it, so this works fine". but doesnt help in learning more...so ignore my above post Envision..haha

 

That's a lot of replies. Seems like there are a lot of ways to do it. However,

I don't think that is gonna work in an external class.
