Config.yml and getConfig() problem

Hello everybody,

I have a problem with getting an Integer from my config.yml file.

My code:

Code:

int x = JumpAndRunPlugin.plugin.getConfig().getInt("0.start.x");

My config.yml file looks like that:

Code:

'0':
  start:
    x: 167

I don't know why it doesn't work...

Thank you for your answers.

 

@Gartenzaun Post the stacktrace please.

 

Do you mean the console errors?

 

@Gartenzaun

He ments the console errors yes.

on a other note could you show how you save it?

from what I think what is going wrong is that you save it like:

Code:

int index = 0;
config.set(index + ".yourpath", somethig); //starting with int litteral
config.save();

maybe you should try:

Code:

int index = 0;
config.set(""+ index+".yourpath", somethig); //starting with litteral string
config.save();

Perhaps it doesn't change anything though, I rarely use ints at the begin of a yaml key so I would assume its being taken litterly by yaml thats why it also adds ' ' in your config, but ive heard from other people it should work as normal keys fine to so maby Im not making much sense there.

 

Thanks for your answer, but it doesn't work too. The config looks always the same:

Code:

'0':
  start:
    x: 136

Code:

int i = this.getConfig().getInt("id." + args[1]);
                            //this works !
                                Location startLocation = p.getLocation();
                                Integer startX = startLocation.getBlockX();
this.getConfig().set(i + ".start.x", startX);

Code:

I tested my code and everything with the Event Listener works until I want to get the int startX from the config file...

 

@Gartenzaun

which line is here: DruckplattenEventListener.java:91 the same as you mentoid on your snippet?

try to use int instead of Integer, as Integer is more the reference type or Object Integers can be null whilst a int cannot.

does this key exist in your config?: "id." + args[1] < the key name 'id', isn't that supposed to be a number?

 

@Gartenzaun Do this:
Instead of this:

Code:

int x = JumpAndRunPlugin.plugin.getConfig().getInt("0.start.x");

You need to add this ,0 so just replace it with this:

Code:

int x = JumpAndRunPlugin.plugin.getConfig().getInt("0.start.x", 0);

 

All that does is supply a default if the config is unable to get the value. It doesn't change the issue that he is still not retrieving the needed value.

My guess is that "plugin" is null. You should not have a public static field that you access, pass your main class instance via constructor.

 

Line 91 is that: JumpAndRunPlugin.plugin.reloadConfig();

And my main class (snippet):

Code:

public class JumpAndRunPlugin extends JavaPlugin {
    public static JumpAndRunPlugin plugin;
    @Override
    public void onEnable() {
        configWerteLaden(); // is defined below
        new DruckplattenEventListener(this);
    }
    public void onDisable() {
        this.saveConfig();
    }

 

@Gartenzaun your plugin variable is null, thats the problem.

 

And how do I solve this problem? In my other plugins it worked...

 

@Gartenzaun First off don't do it that way. Pass instance through a constructor. Second, if you are going to do it that way in onEnable do plugin = this; and in onDisable do plugin = null;

 

Oh sry, I forgot this! Thank you!

Everything works now. Thank you a lot !
