I bet those questions (of this kind) can be solved with a simple google search
umbral ridge
anything can be solved by google search. it's just that people are lazy and need a quick solution. at the end of a day I still don't understand why this channel is for, if eeeeeeverythinggg can be resolved with a "simple google search". So the idea of it, is confusing, however, I prefer not to search much on Google, because people here almost always know what the problem is, how should it be resolved or what I have to change or whatever. but yeah I guess not always..
But you know, whenever you post your code, idiots will be idiots, most of the programmers can be egotistic fucks and immediately start judging your code as if it's a trophy for them to achieve or some toy or a ball they have to catch. It's important to respect newbies, not the ones that use AI and then copy&paste and spam the fuck out of everything, but everyone else, yea

because unloading worlds is not a vanilla concept

for a person that's new in this, that's perfect. it's not like everyone should write code exactly as you would prefer. it doesn't matter if there's a space missing, or any of the visual characters that don't really affect the performance of the code. it doesn't matter if they use switch or the shittiest code possible. if they know what it does, and didn't just copy and paste it from somewhere, then that's fine. As long as they understand it. They'll get better, maybe better than you, me or the whole server. Also most of the people get judged for x problem when they were asking about y.

"Creating computer software is always a demanding and painstaking process -- an exercise in logic, clear expression, and almost fanatical attention to detail. It requires intelligence, dedication, and an enormous amount of hard work. But, a certain amount of unpredictable and often unrepeatable inspiration is what usually makes the difference between adequacy and excellence."

how can i remove a configuration node ? like

deleteconfigurationsection or remove
it doesn't appear in the methods tab

make sure you have the file config.yml in your resources folder, should work then.
solemn meteor
make sure you have the file config.yml in your resources folder, should work the...
So this is wrong?
hazy parrot
its not
solemn meteor
saveDefaultConfig() will write the config.yml file from your plugin's jar file to the plugin's data folder. (If that folder doesn't exist it will be created) It will not overwrite an existing config file.
quaint mantle
its not wrong
solemn meteor
https://www.spigotmc.org/wiki/config-files/ source btw
hazy parrot
everything inside resources folder will be packed inside of your final jar
so if you want to get config, it have to be inside of your resources folder
quaint mantle
you have just to create a config.yml file inside your plugin resources folder
quaint mantle
https://www.spigotmc.org/wiki/config-files/ source btw

so its just there just because?
man
quaint mantle
because you put it within your resource folder, after calling the method the plugin will take the file from the resource folder and put it into your plugin folder
there should be a documentation for it as well if you click on the method saveDefaultConfig() just download the source

you're welcome lol

If you're creating it on load, then you're likely overwriting any existing data. You should check to see if the section already exists.

is there a way to reload plugins without restarting the server, i know /reload exists but i heard I shouldn't run it
idk why though 🤔
tardy delta
you shouldnt run if if you didnt implement it properly
echo basalt
What if we made a JavaPlugin#reload api method that by default just throws an error
And a /reload MyPlugin command
🤔
tardy delta
💀
echo basalt
So plugins that want to support reloading just override and do their own custom logic
sour bluff
i'm sure this is hella funny but idk what this means 🔥
sullen marlin
the whole reload is bad is a myth from shitty plugins
the actual concept of reload is fine
vocal cloud
reload bad. Blowing up server good.
echo basalt
Sometimes we can't bother going over every existing player and loading their data knowing damn well that only should happen when a player joins
sour bluff
okay so i'm coming from skript so is there like a temporary variable equivalent in java or do i just make one and delete it later
echo basalt
There's no "delete a variable"
sour bluff
whar
echo basalt
There are just different visibility scopes
You have local variables, which are defined and only accessible within a code block
tardy delta
java isnt javascript
echo basalt
public void doWhatever() {
int value = 123;
// This only exists within this code block
}
And then there are fields
Which belong to the object
sour bluff
how do you make the shiny like that
echo basalt
public class MyObject {
private final int money = -1;
}
This is a field
Then there's static
Which "belongs to the type instead of the object"

how do you make the ``` ```shiny like that

You can use the discord code block format to display code or just text in a more pleasing way:
```java
public class MyPlugin extends JavaPlugin {
@Override
public void onEnable() {
}
}```
Becomes:
public class MyPlugin extends JavaPlugin {
@Override
public void onEnable() {
}
}```ah
echo basalt
Poor explanation but basically these are accessible everywhere
public static final int money = 123;
And have very specific use-case scenarios and are often abused
They're also kept in memory forever because you never know when someone might reference to it
sour bluff
oh but local variables aren't
echo basalt
Compared to objects which if held no references to, are garbage collected
sour bluff
mee
echo basalt
oh but local variables aren't
No, local variables are only accessible to the code block that defines them
Whether it's a constructor, method or initializing block
sour bluff
alright, so use static when i need to reference it across everywhere, and local when i'm only using it for one thing
rough ibex
eh
echo basalt
alright, so use static when i need to reference it across everywhere, and local ...
Not really no
sour bluff
wopm womp
echo basalt
Anything that's static should be immutable
As in never changing and never being able to change
It's final, constant
And constants ARE_NAMED_LIKE_THIS
echo basalt
public class MyWhatever {
private static final int MONEY = 123;
}
Any field that's static should in best practice be final
summer scroll
Sweet!
echo basalt
Sweet!
rough ibex
nice
sour bluff
fire
echo basalt
Now, given it's static it's always present
But also it's only initialized once - When the class is loaded
And a class is loaded when it is referenced for the first time
Or if someone writes a funky classloader but that's advanced
echo basalt
Fields belong to the object
So if you have two objects
Each object's fields can point to different things
Think of this
public class Person {
private final String name;
private int money;
public Person(String name, int money) { // Constructor
this.name = name;
this.money = money;
}
}
You have a Person class and that class has 2 fields
One's named name of the type String
And the other's named money of the type int
You can create multiple objects:
Person illusion = new Person("Illusion", -1);
Person chaotic = new Person("ChaoticPoly", Integer.MAX_VALUE);
And now you have two objects but with different values assigned to each field
sour bluff
so its object specific variables, as opposed to static which is immutable and global?
echo basalt
Yeah
A field is just a "variable" that's not local
Static values are still fields
They're static fields
sour bluff
🤯
wait so what happens to local varaibles when the code block ends, it just gets garbage collected?
sour bluff
"what happens when a person variable dies"
echo basalt
An object gets garbage-collected when it no longer has any reference pointing to it
When it's held in a static field it's always referenced
So if you create an object inside a method and pass it around or store it in a list, it still holds a reference to it
Until it gets removed from the list or the methods you passed it to finish executing and don't store it anywhere else
Then, and just then, it's queued for garbage collection
There are phases to garbage collection and it's a complex topic but just assume it's "gone for good"
sour bluff
alright
echo basalt
Also a "memory leak" happens when an object's reference is kept beyond the object's expected lifetime
sour bluff
expected?
echo basalt
Think of storing an object in a list and not removing it when the object should be declared "dead" (as in storing a player and not removing it after they disconnect)
sour bluff
so then it cloggs up space
echo basalt
Forever
