leaden knoll
hello! i have some code from some time ago for a config manager class to make multiple config files which i made using a tutorial
it didn't work then and when i modified it yesterday it still did not work (it has an error btw), if anyone can help that would be great! thank you
config manager class: https://paste.md-5.net/ixiqavokiv.cpp
main class: https://paste.md-5.net/isetudoxog.java
error: https://paste.md-5.net/ezibafakig.md
btw it creates the folder and the yml file, but it does not set anything inside it
leaden knoll
i still need help btw
ok so i switched joins.set("test", "hello"); with joins = YamlConfiguration.loadConfiguration(joinsFile); in the try thingie, and it makes the file, reloads it and saves it and everything is fine, but then when i stop the server and start it again, it sends an error
this is the error it sends now: https://paste.md-5.net/juvifovibu.md

You need to call reloadJoins() once before you can do anything else.
acoustic shadow
I think its because you never initialized this.joins before using it
cant save something thats not there
fluid escarp
The error is pretty self explanatory
leaden knoll
oh so i need to switch the save and reload in loadConfigManager in the main class?
acoustic shadow
you can try it
leaden knoll
alr 1 sec
acoustic shadow
or at least put it in the onEnable at the start once
fluid escarp
What you need to do is initialize the joins field before you call methods on it. Thats the core problem.
leaden knoll
i'm already doing that
acoustic shadow
Nullpointer exceptions are relatively easy to fix imo
fluid escarp
How you manage that is up to you
leaden knoll
in ConfigManager() (method, not class)
fluid escarp
Oh i see the problem
joins.set("test", "hello");
joins = YamlConfiguration.loadConfiguration(joinsFile);
^^^
fluid escarp
joins is null.
Then you call joins.set()
which results in a NullPointer
Switch those two lines
leaden knoll
oh so i need to switch the save and reload in loadConfigManager in the main clas...
ok so i did this and no error, lemme try to restart, and then delete, and then restart twice just to triple check
fluid escarp
You need to first initialize a variable or else its null.
And if you call a method on a variable thats null you just get a Nullpointer
acoustic shadow
the reload method initializes the join variable which basically just goes around the error of putting joins.set before joins = ...
thats why its not giving an error
acoustic shadow
if you put the reloadJoins method before the other one you have joins = YamlConfiguration.loadConfiguration(joinsFile);
leaden knoll
i take that back, no errors but the file doesn't have anything in it
acoustic shadow
not seeing what you want it to put in
leaden knoll
just the test: hello for testing
acoustic shadow
oh that
not sure on that. maybe try putting an extra method to put those test values in and call it after youre done creating the file
leaden knoll
alr
somethin like this and then call it in the main class after the reload and save?
public void testingJoins() {
System.out.println(joins.get("test"));
}```I meant something like put the joins.set() into an extra method to call after youre done making the file
leaden knoll
but the set thing is already after i made the file
leaden knoll
somethin like this and then call it in the main class after the reload and save?...
also this just sends null to console
lemme try ur thing
acoustic shadow
yeah if theres nothing to get from that path its gonna return null
acoustic shadow
tbh wasnt expecting it to
acoustic shadow
ok you might have to repaste the things you have now
leaden knoll
public void testingJoins() {
joins.set("test", "hello");
System.out.println(joins.get("test"));
}```sends `hello` to console, and yet when i check the file it's emptydo i need to add a reload in the middle?
acoustic shadow
close and open the file
leaden knoll
it's empty
acoustic shadow
I think you might need to add a section?
acoustic shadow
if you add the path "test" by default it will set that path to "hello"
leaden knoll
(not that i knew much in the first place)
leaden knoll
how do i use that
acoustic shadow
joins.createSection()
leaden knoll
???
i just added the reload line in the middle and now it's sending null to console
huh
acoustic shadow
maybe try this?
leaden knoll
what that do
acoustic shadow
read
leaden knoll
oh ok
leaden knoll
the tutorial i used for this is also very old
acoustic shadow
https://helpch.at/docs/1.11/index.html?org/bukkit/configuration/ConfigurationSection.html
This could also be of help.
leaden knoll
maybe try this?
didn't work
acoustic shadow
didn't work
then you should try creating a section with the intended path, then setting the value of that path to the intended value
leaden knoll
sorry again but i don't understand
acoustic shadow
sorry if Im feeding you a little more code than you would want in the next message
joins.createSection("test");
joins.set("test", "hello");
Im also not very good at YML files so this might just be wrong tbh
acoustic shadow
Ive gotta head out. sorry, maybe ask someone else in the help development channel
leaden knoll
alright, thanks

check this video out

leaden knoll
this is from a tutorial tho
not the same one but i just want to get this one working
split kiln
Well you said that one was 3 years old anyways, and I know for a fact that tutorial works
Why are you trying to create config sections anyways? You can just do config.set(path, object)
Also from the errors it says joins is null
Did you set joins to an instance of your config class onEnable?
leaden knoll
i'm not trying to create sections, we were just trying stuff
and the error is long gone, it just doesn't set the text in the file anymore
grand sequoia
Hi yes what were you asking for help with
I sat with configs for a while myself
@leaden knoll
leaden knoll
okie, do you know what i can do to fix this issue?
lemme get the code and stuff
main class: https://paste.md-5.net/okiponerev.java
config manager class: https://paste.md-5.net/qojofimela.java
it creates the file but nothing in it
grand sequoia
Yeah do you have a config.yml?
leaden knoll
i have joins.yml
grand sequoia
It creates the config from a base file, or whatever you've added to it through that
The plugin generates joins.yml but it's empty, yeah?
leaden knoll
yes
grand sequoia
The way I've come to understand how it works is that the config it generates is blank unless you yourself have made a default one
leaden knoll
what's that mean
grand sequoia
Basically it means if you don't want a blank default config, you have to create the stuff you want in your config
Like if you want the default config to contain something like
leaden knoll
wdym by default config
grand sequoia
Let me backtrack a bit, what do you want that config to have in it?
The one that's automatically generated
leaden knoll
in joins.yml i want to add all uuids that have joined the server
brb tho, i need to eat
grand sequoia
And did you add code to do that? Like code that will save the UUID's ?
I see there's "getJoins" but it returns "joins"... what is "joins"?
Unless I'm mistaken, what you want is an event listener that checks for PlayerJoinEvent, then grabs the UUID and saves it to your file
I'll try write up something and see if it works then I'll send it here
leaden knoll
back
doing it on join isn't the problem, as you can see in the main class, it's supposed to get the config file and then set something in it, but that doesn't work for some reason
grand sequoia
Oh
So adding stuff to the config is where you have an issue?
Okay that helps a bit, where is it you're trying to do that?
Like what line in what file
leaden knoll
last line in loadConfigManager in main class
leaden knoll
main class: https://paste.md-5.net/okiponerev.java
config manager class: https:/...
^^^
grand sequoia
Yes ofc but where in there are you trying to save the info
oh woops
Missed your message before that
leaden knoll
oh and before this, i put the set thing in the config manager class in the try thingie and it set it but had an error
like it would create and set and whatnot, but then when i restart it would send an error
grand sequoia
Yeah I am pretty sure there error here is that there is no config
Like
There is but there isn't
create a file in your resources, where the plugin.yml is, and call that whatever you want it to be called, same as you're calling it in the code
Then add "Test:" to it, save that. Run your code
leaden knoll
i don't understand, sorry
grand sequoia
Do you have something like this, with the plugin.yml?
You should make another file there, call it "joins.yml" or whatever it is you assigned the config to be named, then add "test:" as the first line and save it
leaden knoll
ok i figured it out i think
grand sequoia
Your code is trying to save "Hello" to a section of the config that doesn't exist
leaden knoll
i just needed to add the save method after i set it
