Solved Referencing public variables from main, in listener?

Hey there,

So inside my main I create a hashmap that stores an integer value.

Code:

public final HashMap<Player, Integer> PlayerClass = new HashMap<Player, Integer>(); 

I attempt to read this from my listener class but I receive an error.

Code:

<MainName>.this.PlayerClass.get(Whatever) == Whatever

What am I doing wrong? Am I attempting to access the hashmap wrong?

 

Pass your main class' pointer to your other class through the constructor.

Accessing it by ClassName.var means that you're requesting a static object, as opposed to instanced object which currently is.

 

How would I do that in code?

 

http://wiki.bukkit.org/Plugin_Tutorial#Using_a_separate_CommandExecutor_class
Example with a command class, ignore the commands part, see the constructors and how they create the other class.

 

I read the whole page, but I'm still having difficulties understanding what I need to do.

If you would be so kind, explain it to me like i'm a 4 year old.

 

Code:

  
        private MyPlugin plugin; // pointer to your main class, unrequired if you don't need methods from the main class
 
        public AnotherClass(MyPlugin plugin) {
            this.plugin = plugin;
       
 
    }

'AnotherClass' is the class name.


You would then use inside AnotherClass

Code:

plugin.PlayerClass.get(Whatever)

 

I feel really stupid.



What in gods name am I doing wrong?

That's not named like the class, click "Change to constructor".

 

Alright?

So I have the following.

Code:

private MinecraftLegend plugin; // pointer to your main class, unrequired if you don't need methods from the main class
 
    public MinecraftLegend(MinecraftLegend plugin)
    {
        this.plugin = plugin;
    }

When I go into my playerLis class and try 'plugin.PlayerClass.get(whatever)'

 

public MinecraftLegend(MinecraftLegend plugin)
should be if its in your PlayerLis class
public PlayerLis(MinecraftLegend plugin)

 

Make it static? Rofl
