Solved Plugin cannot be null?

Hey! So I am getting this error in a scheduler in the listener class! Stacktrace:

05.06 07:59:11 [Server] INFO Caused by: java.lang.IllegalArgumentException: Plugin cannot be null

MatchAPI Line 54:

Code:java

        taskID2 = Bukkit.getScheduler().scheduleSyncRepeatingTask(plugin, new Runnable() {

I tried this but did not work:

Code:java

    private static Snowma plugin;
 
 
    public MatchAPI(Snowma plugin){
        MatchAPI.plugin = plugin;
    }

Help!

 

HeavyMine13 Full code please.

 

Stop using static. That is most likely the cause of your issues. HeavyMine13

 

Why? I need to use them in other classes ._.

Of which class?

HeavyMine13
So pass instance through a constructor of those classes then?

 

HeavyMine13 Preferably both the main and the Listener. And I agree, statics aren't the way forward.

 

Hmm example?

 

HeavyMine13 http://docs.oracle.com/javase/tutorial/java/javaOO/constructors.html

 

HeavyMine13
You just did one? The one with MatchAPI.

 

Im using public static void thing(Parm m){
//do stuff
}

Whats the difference?

Ok if I change it(Which I can easily do), how can I use it?

I have multiple statics I cant just turn each of them into MatchAPI(Parm)! Right?

As Gater12 pointed out... Here is an example of it being used

It should look reasonably familiar. Change it to "this" rather than MatchAPI and remove the static from the variable, and there you have it!

 

what static? there is no static in that constructor!

 

HeavyMine13 I mean the "plugin" field.

 

Ok now after all is ok and removed many static, how can I use public void addPlayer(Player p){//blah} in the main class?

 

HeavyMine13

1. Create an instanceof the API in your main class
2. access addPlayer(Player p) because it is most likely public
3. ???
4. profit

 

Umm I need help with step 1 ._.

 

HeavyMine13

Code:java

// From the main class, we use this.
new MatchAPI(this)

 

Ok addPlayer is public but how can I access it? Sorry, this is time #1 i dont use statics xD

 

http://docs.oracle.com/javase/tutorial/java/javaOO/usingobject.html

 

HeavyMine13
MatchAPI api = new MatchAPI(this);
api.addPlayer(Player);

woops haha, I have now realized I have tagged the wrong person, fireblast709, sorreh

 

Thanks alot #FacepalmHEavy

Thanks anyway the docs helped! Next time ill research myself before I post lol

HeavyMine13 To nake it easy on yourself, you could always create a stastic instance of your class inside that class that will be initialized on startup. So basically somewhere in your class:

Code:

public static MainClass mainClass = null;

In your onEnable()

Code:

mainClass = this;

 

that didnt work last time with me
