frigid ember
formal nimbus
alright
wispy pewter
SO now there is always one instance of the calss
unless someone manually creates a new instance.
mellow wave
The static way I showed always creates the instance the first time the class is accessed either way both works
mellow wave
How you choose to do it is up to you
wispy pewter
But its always better to prevent access to the Field
formal nimbus
how do I get the class instance?
wispy pewter
Just copy this and rename Class1 to your class name
private static Class1 _instance;
public static Class1 getInstance() {
if(_instance == null)
_instance = new Class1();
return _instance;
}
the new Class1() line creates a new instance object of the class and sets it to the private instance field
^^
The null check makes sure it wont create a new instance everytime the static method is getting called
mellow wave
oh and make the constructor
private Class1() {}
This way no one can create a new instance
wispy pewter
it doesnt require to have a constructor
mellow wave
That just makes the constructor private
wispy pewter
You can create new instances without having a constructor
mellow wave
It will stop users from using new Class1() outside of the Class1 class
wispy pewter
Yeah thats true
formal nimbus
yus
mellow wave
Now do whatever you'd like. Let's say add those constructor values you wanted in to the private constructor
formal nimbus
wispy pewter
@formal nimbus The reason why the field is private is because if there is allot a data being stored in the class people cant reset the instance.
formal nimbus
ok so that means I can make those things not static
since I'll only ever have 1 instanceo f the class anyway
formal nimbus
lombok?
mellow wave
It's an utility that adds annotations such as @Getter and it will generate getters for you
formal nimbus
o
mellow wave
It's quite convenient when you have a lot of getters and setters
wispy pewter
^
wispy pewter
@formal nimbus TIP: Use as less static members as possible
wispy pewter
If you're working with interfaces you can use dependency injection
formal nimbus
dependency injection?
wispy pewter
Because static members should only be used when needed
mellow wave
^
wispy pewter
otherwise your program can become filthy
formal nimbus
lmao ok
wispy pewter
I forgot how to explain it in englishKEK
formal nimbus
we have a code purist over here
mellow wave
There are certain cases when you need static but usually you don't need them very often
wispy pewter
Its preffered to only use static members for Utily/Helper classes
formal nimbus
I have a list of objects which I want other plugins to be able to use
wispy pewter
And ofcourse when you're working with Singletons
formal nimbus
how do i do that?
wispy pewter
Make a getter for it
mellow wave
^
wispy pewter
People should never be able to directly access the fields
formal nimbus
so they'll be able to use the public getter?
mellow wave
Yes
wispy pewter
since they are major to your code
formal nimbus
k cool
mellow wave
If they can get the instance of the class they can use a public method
wispy pewter
^
formal nimbus
how would they get an instance of my class?
wispy pewter
with the getInstance method
mellow wave
^
wispy pewter
When its called for the first time it creates a new instance of the class and sets it to the private field
formal nimbus
heh
wispy pewter
This makes sure there is always a single instance floating around
formal nimbus
aight
wispy pewter
Which means: Less memory usage = faster and responsive code
formal nimbus
but how do you set it up so the 2 plugins cace?n interact in the first pla
wispy pewter
You mean when 2 plugins call it at the same time?
formal nimbus
how would somebody else make my classes become visable to their IDE?
mellow wave
You add the first plugin as a dependency
formal nimbus
ah
mellow wave
How you do that is up to you
formal nimbus
ok, so like you do with spigot API
mellow wave
Yes
wispy pewter
let me create a example for you
formal nimbus
sure
wispy pewter
With some explenation about what it does
formal nimbus
it's annoying, every day I find some new thing I've been doing wrong with my code xD
but on the plus side I guess it means I'm learning
wispy pewter
I've been programming in C# for 4 years and still learning everyday
wispy pewter
When you know C#, java is childs play
echo path
i need some help im getting a error for my plugin cn anyone help me
mellow wave
They're very close
echo path
i cant send pictures idk why can i dm them to u?
wispy pewter
Sure go ahead
@mellow wave Dumb question. How to create a summary about a member?
in C# you can like /// <summary>
formal nimbus
They're very close
@mellow wave nice 😮
wispy pewter
Dumb question tho 😂
formal nimbus
I guess learning C# should be no problem then
I guess it's similar to learning languages
natural ones I mean
except coding languages will be even more similar, just with different syntax
wispy pewter
Syntax
formal nimbus
?
formal nimbus
? ?
wispy pewter
constant variables should be UPERCASE
formal nimbus
o
wispy pewter
So other people know they are constants
formal nimbus
I haven't been following that scheme
mellow wave
It's naming conventions
mellow wave
You can find them if you look them up
wispy pewter
Naming conventions is not a mandetory thing to do
formal nimbus
right
mellow wave
^
wispy pewter
but recommended when working with API's
formal nimbus
well maybe in my next project I'll use it
for now though I'll just stick to using camel case for everything
wispy pewter
For starters its better to learn what the acces modifiers are
and what the diffrences are
formal nimbus
yus, I think I've at least got that down lool
I find it infuriating how you can't change the name of a GUI after it's creation
*an inventory
would make life easier ):
wispy pewter
public class DataManager {
//This field holds the singleton of the class. The reason its private is because we dont want people to create a second instance.
private static DataManager _instance;
//Holds a collection of names. The reason that its private is because we dont want people to directly access it.
private final List<String> _names = new ArrayList<String>();
private DataManager() {}
public static DataManager getInstance() {
if(_instance == null)
return _instance = new DataManager();
return _instance;
}
public List<String> getNames() {
return _names;
}
So lets say you have a data manager class that stores data
That means you dont want to have multiple instances floating around.
The perpose of the singleton is to ensure there is always a single instance.
formal nimbus
uh huh
wispy pewter
For example. in this sample you see a List of names right?
wispy pewter
Well if people constantly create new instances the names collection will never be the same
formal nimbus
yep
wispy pewter
Because we dont want people to access the field directly
formal nimbus
or if you had a constant, you would end up with duplicates of the exact same thing
wispy pewter
because then they can screw up the behaviour and the data
formal nimbus
yee
for something like this
it's an ItemStack factory (I think?)
anyway it's a helper method
can I just make it static?
wispy pewter
Factories basically provide a easier way of creating instances
formal nimbus
right, so it is a factory then
wispy pewter
Your createItem method should be static
formal nimbus
with a lot of helper methods
I could make the class static
as long as it doesn't store any data
wispy pewter
Creating a static class means its members can only be static
wispy pewter
Everything inside a class are defined as members
See a class as a blueprint
they store data
For examplle you have a person class that stores the Name, Age and Gender of the person
Its basically a blueprint of a person
wispy pewter
Uuh lets see. In C# this works so....
😂
I never really got into java
its different in some aspects.
wispy pewter
As i see, java doesnt support static classes
But its not a big problem since you can create static methods only
formal nimbus
yep
wispy pewter
After you got the understanding of how classes work, go try to refactor your code
Like create certian fields readonly
Thats why in my code example the names list is marked as final
So java knows it will never be re-instantiated
Which results in saving -up memory
Which corresponds to a faster plugin.
formal nimbus
yus
I've already been trying to make all the variable which I can final
can I make an ArrayList final?
I mean it changes in size
@wispy pewter
wispy pewter
yes it can
formal nimbus
o
wispy pewter
final aka readonly means it can only be instantiated one time
if you want to know better info call me
I can explain better in call.
wispy pewter
Call me if you can or want
twin cosmos
can someone help me i got an error in
plugin.getConfig().getString
wispy pewter
I will give a proper explenation of a factory's work
and why and when you should use private and final
@twin cosmos The plugin variable is only available in the main class of the plugin
Make a instance of the main class
and call it trough there

it was 65 lines before lol
mellow wave
Nice :)
wispy pewter
Amazing
mellow wave
@celest current No need to do a == check to true. That's just redundant
wispy pewter
Your getInstance is missing the null check
formal nimbus
it's allowed me to make the saver final too 😄
balmy sentinel
you don't need to add the "this."
hollow thorn
hat materials cant be used for crafting? because for some reason whenever i try to use Iron Ingots in a crafting recipe the recpie no longer exists
wispy pewter
you don't need to add the "this."
@balmy sentinel Not needed but it makes your code more readable.
better would it to change to super.
so you always know it refers the the class it inherits from.
hollow thorn
hat materials cant be used for crafting? because for some reason whenever i try to use Iron Ingots in a crafting recipe the recpie no longer exists
formal nimbus
I just realised that bukkit already has a class called ItemFactory :/
mellow wave
It's for ItemMeta
formal nimbus
and I named my ItemStack factory class ItemFactory ;-;
mellow wave
That's fine just make sure you import the right one

All materials work fine for crafting
formal nimbus
aight
wispy pewter
Well guys, I'm going to eat
lone fog
Aside from ones that don't exist as items
wispy pewter
See y'll soon
celest current
@celest current No need to do a == check to true. That's just redundant
@mellow wave if I only have one = than this happens: http://prntscr.com/tty34s
lone fog
don't add any at all
twin cosmos
@wispy pewter ty
wispy pewter
because the = operator is used to define variables
lone fog
You can just do if (boolean)
wispy pewter
just use if(boolean)
mellow wave
Remove = true @celest current
wispy pewter
I would also recommend to create a custom variable for the getconfig
so you dont have to write that piece of code everytime
formal nimbus
.getBoolean("crafting.xp-bottle") already has a boolean value
by default, if() will check if something is true
mellow wave
And the way you're getting the recipe is depricated an item may have multiple recipes
wispy pewter
var config = instance.getConfig();
formal nimbus
so you don't need to check if it's true, as the if statement already does it
wispy pewter
try making your life easier
lone fog
Add a namespaced key to your recipe
celest current
yeah asking if its true is redundant
formal nimbus
lol this poor guy is being bombarded by a million criticisms xD
celest current
Nah mate I love it
wispy pewter
Criticism makes you better
formal nimbus
tru
mellow wave
Anyway did you see what I said about the way you're getting the recipes. Use Bukkit#getRecipesFor instead and read the list
lone fog
Constructive criticism makes you better
celest current
The people in this community are mega bigbrain so their criticism is usually really good advice
wispy pewter
@celest current When you have to write a line ass line to acces something, Make it easier by making a custom variable
It makes your life way easier
And also makes your code cleaner 😉
Incase you want to flex on some noobs
celest current
instance.config() = config or sumn like dat
wispy pewter
var config = instance.getConfig();
celest current
uno reverse to the max
mellow wave
var doesn't exist in java
celest current
thats JavaScript
wispy pewter
it works for me 😉
mellow wave
Yeah I believe 10
formal nimbus
Hmm
jagged torrent
its not in 8
formal nimbus
Olivio/MichielA, can't private fields be changed using reflection, so making them all private is kind of redundant?
mellow wave
@wispy pewter JDK 14, most servers use 8 which does not have var
wispy pewter
Yeah could be related to the version of java
lone fog
Just because they can doesn't mean they should
wispy pewter
@wispy pewter JDK 14, most servers use 8 which does not have var
@mellow wave Ooh oke. Didnt know that, thanks.
mellow wave
I've always used 8 so I didn't know they added var
lone fog
If someone is using reflection they should know that the field wasn't meant to be changed that way
wispy pewter
fuck off bot
wispy pewter
Reflection can access anything
mellow wave
^ It's really useful
formal nimbus
right, so what's the point of making everything private and making getters and setters
if it can be changed by reflection?
wispy pewter
formal nimbus
why not just leave it public
wispy pewter
Mentions one person
mellow wave
Reflection is slow
wispy pewter
why not just leave it public
@formal nimbus Because private fields can only access in the calss itself
mellow wave
Yeah I have 2 warnings for typing the same message 2 times :&
lone fog
And encapsulation is good practice
formal nimbus
@formal nimbus Because private fields can only access in the calss itself
@wispy pewter but they can be accessed using reflection...
lone fog
Plus getters and setters can add additional logic
formal nimbus
And encapsulation is good practice
@lone fog but why
mellow wave
Reflection is slow and if someone uses it they most likley know what they're doing. I doubt some new to java would use it
formal nimbus
right soo
it's to stop values being changed by people who don't know what they;re doing?
wispy pewter
reflection is more for advanced users
@formal nimbus https://www.javatpoint.com/access-modifiers
mellow wave
Anyway don't worry about someone using reflection on your class. If someone messes up it's their problem
wispy pewter
Now i need to go afk
formal nimbus
Anyway don't worry about someone using reflection on your class. If someone messes up it's their problem
I guess
lone fog
It 100% is
I could use reflection to change true to false, but that would break everything and it would be my fault
wispy pewter
I dont want to leave xD
celest current
instance.getConfig().getBoolean("crafting.powerdirt") still doesnt work tho? Its set to false in config but I can still craft the almighty dirt cube of ultimate power and strength

formal nimbus
repeat
lone fog
If you have security concerns you can use a SecurityManager
formal nimbus
If you have security concerns you can use a SecurityManager
@lone fog lol I don't, but I'm just thinking of programmes which need security
wispy pewter
If you want security go obfuscate your code
mellow wave
They probably will use C++
formal nimbus
right
mellow wave
Or some obfuscation

Doesn't matter add the check
hollow thorn
also is this error exactly the same to the last one https://paste.md-5.net/ibovixebis.cs
mellow wave
Not the same
That error is an ArrayOutOfBoundsExeption
You tried to use a value in an array that doesn't exist
In this case the ArrayList on line 278
Now you should probably learn how to read those errors, there are guides online

People really need to read their errors and understand what they mean.

Whats the best way to check if a player has certian items in inventory? This is what I have and it doesnt seem to go into the next part after Checking for Gold Ingot:
if(inv.getItemInHand().getType().equals(Material.GOLD_INGOT)){
ItemStack pin1 = new ItemStack(Material.POTATO, 1);
ItemStack pin2 = new ItemStack(Material.LEASH, 1);
if (p.getInventory().contains(Material.POTATO) && p.getInventory().contains(Material.LEASH)) { p.getInventory().getItemInHand().setAmount(p.getInventory().getItemInHand().getAmount()-1);
p.getInventory().remove(new ItemStack(pin1));
p.getInventory().remove(new ItemStack(pin2));
}
}```Use == instead of .equals() when comparing enums
if (inv.getInventory().getItemInMainHand().getType() == Material.GOLD_INGOT) {
// le code
}```Might fix your problem, but put some debug outputs in there to see how far it gets
frigid ember
ok ty
rustic glade
Use == instead of .equals() when comparing enums
if only Java had operator overloading...
with Java, when comparing things, you'll almost always need to use equals
wispy pewter
If you're working with multiple enum checks i recommend using the switch-case statement
winged sparrow
^
wispy pewter
Cleaner and faster Code
frigid ember
well in reality it will need to check if you have 25 different items in your inventory and ifso remove 1 of each and run the rest of code
Im testing with 2 before adding more
winged sparrow
in that case definitely use a switch-case statement.
wispy pewter
if you dont know how switch case works, here is an example.
Animal Enum:
public enum Animal {
DOG, COW, CAT, SHEEP
}
Switch-Case
public class Main {
public static void main(String[] args) {
Animal animal = Animal.CAT;
switch (animal)
{
case DOG:
Log("Doggo");
break;
case COW:
Log("Big Cow");
break;
case CAT:
Log("Cat");
break;
case SHEEP:
Log("Sheep");
break;
}
}
static void Log(String msg)
{
System.out.println(msg);
}
Oh.... I think (maybe im wrong) but I wanted it to check if player was holding the gold_ingot in main hand, then if true, check if they are holding 25 other items in their inventory, and if true remove 1 of each item of the prior 26 materials and run an event so switch-case wouldnt work?

Anyone has an idea whats the best way to make a 1 Block wide world?

solid sundial
ok, I've been trying to make a NPC plugin. rn I have it so that when you shift + right click it selects the NPC. I dunno how I want to store which NPC is selected but if someone knows, that would be AWESOME!
winged sparrow
@solid sundial I'd just use a hashmap
with the player uuid as the key and the npc or entity object
solid sundial
public static Map<Player, EntityPlayer> map = new HashMap<>();
winged sparrow
I'm not experienced with messing with packet generated entities but aren't packet generated entities not real entities?
I'd recommend giving the npc an id and call to it using some other method to retrieve it
solid sundial
yeah
i've been wondering if I should make some kind of id, but i dunno how...
do you?
solid sundial
wat
winged sparrow
why is that map static exactly?
bold anchor
A npc will also have an uuid use that not the npc object
solid sundial
it is static because i want to use what is in the Map in my commands
wait, a uuid
how can i find that?
solid sundial
wat that
wispy pewter
Dependency injection is not needed probably
Singleton is fine
Dependency injection is more for working with Interfaces
solid sundial
i guess ill just mess around with the syntax 🙂
hollow grail
People can't write, doesn't write enough rights! What to do? Plugin: ChatEX
solid sundial
ok, so when player selects.
map.put(event.getPlayer(), event.getNPC());
what should i put instead of getNPC?
winged sparrow
I'd honestly store just the uuid of the player, and the uuid of the npc
solid sundial
so...
winged sparrow
so it stores less information in the cache
frigid ember
@hollow grail What permissions plugin are you using
winged sparrow
I typically just use the UUID format, is there a particular benefit to using a ulong?
solid sundial
i dunno what you are talking about? but what should i put instead of getNPC... lol
solid sundial
im confused
wispy pewter
@winged sparrow Its in long xD
wispy pewter
I forgot java doesnt support unsigned integers does it?
winged sparrow
so, new Map<UUID, UUID> map = new Map<>()
wispy pewter
I wouldnt really recommend using a class as key
jagged torrent
UUID is 128 bits -> 2 longs
winged sparrow
🌈 the more you know
solid sundial
yes
wispy pewter
i'm used to C#
hollow grail
@frigid ember luskperms
wispy pewter
where we have uint, ulong etc
jagged torrent
hence why you store it in a database as BINARY(16) and not varchar
solid sundial
npc is my class
hollow grail
but I didn’t do anything in it, it was just installed.
wispy pewter
I like Struct
solid sundial
how to get the UUID of that specific npc... am i stupid idot
winged sparrow
Well if it's a EntityPlayer, there should be some kind of method to retrieve it
winged sparrow
getUniqueId()
winged sparrow
is the method you use for getting uuids from players and entities
wispy pewter
UUID = Universally unique identifier
solid sundial
yeah... getUniqueId of player works
but when i do NPC.getUniqueId it asks me to make a new method
tiny dagger
cough except for minecraft devs
wispy pewter
bedrock
winged sparrow
EntityPlayer is a nms data format, right?
you're gonna have to do some digging for that.
wispy pewter
Check the docs lol
wispy pewter
There is a reason why there is something called "Docs"
frigid ember
@hollow grail you need to give the players the correct perms for ChatEX to type then
solid sundial
wait, some of you are saying to make my Map <UUID, UUID> and some are saying <UUID, EntityPlayer> which one
winged sparrow
Is it a bad idea to hijack player messages on the chat event and replace it with a textcomponent?
Store two uuids
one for the player, one for the selected npc
I don't recommend storing class objects in maps
winged sparrow
Good luck!
solid sundial
thanks 🙂
winged sparrow
EntityPlayer nmsPlayer = ((CraftPlayer) player).getHandle();
nmsPlayer.getUniqueID();```
@solid sundialgetUniqueID() is a easily accessible method from an entity player
winged sparrow
And that will give it to you
solid sundial
see my mistake
winged sparrow
That should be exactly what you need
solid sundial
THANK SO MUCH EVERYONE!

Don't.

Abstraction or reflection i suppose

Abstraction is probably best
Though I don't think MD likes to remove stuff like that anyway

He will probably rip it out suddenly when he feels like it’s annoying

probably no tool
I would say make your own /summon that takes those args and gives you something more useful for usage with api
and then just run your 200 commands
or just make a parsing script

Why are you creating a simpleDateFormat and not using it
frigid ember
but it will literally give the System.current.timemillies
yes
how can I properly use it?
I tried it
but then it says it hasnt been itialised
I put it like this:
death.add(new Data(e.getEntity().getLocation(), e.getDeathMessage(), System.currentTimeMillis()));```System.currentTimeMillis()
then it should be converted to the regular time
when the command gets executed
lone fog
sDF.format
lone fog
SimpleDateFormat sDF = new SimpleDateFormat("HH:mm");
return sDF.format(time);
Won't be a long anymore
Think it's a string
frigid ember
yes
frigid ember
millieseconds since 1997 yea
but can be converted to real time
death.add(new Data(e.getEntity().getLocation(), e.getDeathMessage(), System.currentTimeMillis()));
System.currentTimeMillis() = long
lone fog
1970 actually
frigid ember
so what should I put
lone fog
SimpleDateFormat sDF = new SimpleDateFormat("HH:mm");
return sDF.format(time);
frigid ember
yea
but put it into the hashmap
deaths.add(new Data(e.getEntity().getLocation(), e.getDeathMessage(), System.currentTimeMillis()));
System.currentTimeMillis = long
