Can you send the ArenaManager class line 12

shy fox Dec 11, 2021, 2:56 PM

#

Yeah

#

I can't screen

#

waint

#

public class ArenaManager {
    private List<Arena> arenas;

    public void addArena(Arena arena) {
        arenas.add(arena); //Line 12
    }

#

but why I haven't a default config

prime kiln Dec 11, 2021, 2:59 PM

#

you didnt initialized arenas

#

create a constructor and initialize it

#

Your configs are likely fine

#

you just have this error

#

I initialise my variable why I need to initalise a another in the constructor ?

shy fox I initialise my variable why I need to initalise a another in the constructor ?

Your initializing ArenaManager but not the ArrayList inside ArenaManager

#

so when you add add on that list, it doesnt exist

#

hence the NPE you get

shy fox Dec 11, 2021, 3:03 PM

#

OK

prime kiln Dec 11, 2021, 3:04 PM

#

Constructors like this are useful as you can initialize variables right when you call new YourClass()

#

If i didnt initialized my HashMaps in my constructor, i would be in the same boat as you

shy fox Dec 11, 2021, 3:05 PM

#

okok

#

I see now thx

OK no error now BUT my default arena when I create don't take the basic config parents and key. that what's I want and it's my arena.yml file in ressources of the plugin:

arena:
  exemple:
    world: world
    loc1: 0.0,0.0,0.0
    loc2: 0.0,0.0,0.0
enable: false

So are u agree with that/

if (!arenaFile.exists()) {
          try {
                arenaFile.createNewFile();

                arenaConfig = YamlConfiguration.loadConfiguration(arenaFile);
                YamlConfiguration defaultArena = YamlConfiguration.loadConfiguration(this.getTextResource("arena.yml"));
                arenaConfig.addDefaults(defaultArena);
                arenaConfig.save(arenaFile);


            } catch (IOException e) {
                e.printStackTrace();
            }

        }

#

I have nothing in my file

prime kiln Dec 11, 2021, 3:16 PM

#

If you want to save a config file from a config inside your jar

#

use YourMainPluginClass#saveResource("pathThatsInsideYourJar");

#

it skips all that file creating stuff

#

and you can just load it from File after creating

#

#

my yaml is different since im extending YamlConfiguring

But its the same concept

shy fox Dec 11, 2021, 3:18 PM

#

Ok ok I see

prime kiln Dec 11, 2021, 3:19 PM

#

Also tip you can do your config files like this:

#

and you can access things like so:

#

#

thats upto you if you want your config files like that

#

but may help make it a little easier to read

#

If you do it like that just make sure to copy my constructor
