think of it like this:
Instead of having 1 decent person at doing their job, you hire an assistant
except what if the assistant is faster than the "master"?
you can have desync issues
It still has benefits though
The "assistant" can chip away at bigger tasks while the master processes smaller, crucial tasks
For example, instead of lagging your server with processing chunks, you can make chunk snapshots and let parallel threads process the blocks
then have the main thread operate based on the outcome of those parallel threads
Or instead of letting your main thread stall for IO, you can make a dedicated thread for it and let your main server actually process stuff
But just like training an assistant or explaining the job to them, creating new threads also has overhead

if it was me, I wouldn't make projectiles invisible. I would just do the math to make it look like there is one invisible
not like anyone can see it anyways so why have an entire entity consuming resources for this

give me a bit, in a game and I will grab some links
You would probably use the values that are for a fireball since that is what would be similar in regards to a snowball
wet breach
you get the trajectory
this is where some trig or calculus comes in 🙂
you know where the players are at any given time
you just have to look at the trajectory of both, do some math and you will know if it should hit or not
the reason this is more optimal then spawning an invisible entity, is because all of this math stuff can be done in its own thread that doesn't affect the server
where as that spawned entity even invisible, the server has to keep track of it now and everything else

smh it holds a bigint internally
here is something to help you in regards to bitshifting since it was discussed some time ago, for every bitshift to the left, its 2 to power n(being the amount being shifted over). so lets say its 5 for the start number. its 5*(2^N) and if its a right shift, we divide instead. In case you want to try optimizing at some point 😛
wet breach
also
in regards to bitshifts
if you are shifting between 0-31 places, an int works, if its higher you need a long up until place 63
after that you need a BigInteger

Alright, so I am trying to find a way to shorten my config files a little bit. Right now, if I want to give each list a unique state in the lore, I need to have a list of sections proportional to the length of the list. I really don't like this as it just adds unnecessary length to the config file. Especially when the list contents are identical except for the additional styling.
So what do I have in mind? A placeholder of sorts. However, this isn't without issue. The two problems I have with this are:
- Finding a way to replace the placeholder with a list of strings.
- Applying the styling to each unique case.
I have no clue how to approach the second one since the styling is variable. As it stands, they do share a common format. (<Indicator> <Text>) So maybe I could take advantage of this somehow?
The config problem can get bad quickly. Here's two example configs to show the difference that I am trying to achieve.
Example 1 (18 Lines Reduced)

Then to get it's wrapper you do var contents = YamlConfiguraion.loadConfiguration(f);
contents.set("item-on-cursor", yourItem);
and contents.save()

why var?
fluid river
so what's the difference between YamlConfiguration and just a normal file
YamlConfiguration is a wrapper for FileReader and FileWriter. With YamlConfiguration you can store some predefined Bukkit things to yml file(like itemstack)

JITC will carry it out anyways

inv.setItem(slot, item.build());

basically you read file with YamlConfiguraion.loadConfiguration(File), save it to variable, then use a lot of .set(), and .save() in the end.
So you don't have to write 9999 lines of code to work with YML yourself

i mean
You can store everything in one file

and ints and strings
like in essentials config

You just need to use .set() multiple times
and don't save 2 values on one path @reef lagoon
new value gonna replace old one

fluid river
It's better if you use included YamlConfiguration class

and the itemmeta has thhe custom modeldata?
reef lagoon
the path is item: in this case right

so just item?
tardy delta
hmm looks a bit hotter already
fluid river
so just ``item``?
If you want this kind of storage
you need "previous-item.material"
and so on
separated by .
If you store a list of strings, it would look like this
rancid elm
and the itemmeta has thhe custom modeldata?
fluid river
Can you show

I bet it doesn't store itemmeta(custommodeldata, nbt tags)

You don't even need a scheduler for this

i gotta add dependency somehow

the entire point of a reflective access to NMS is to not depend on the server impl isn't it ?

you'd have to move that logic into a listener
and listen for the player inventory changing

there is no such event tho

you're missing an if

remove the if?
serene sigil
alr
iron glade
you're checking in the next line
serene sigil
btw that ignore that boolean
iron glade
If a player has 50 levels removing 100 just sets them to 0 I suppose?
serene sigil
ye ig
iron glade
alternatively you could remove those levels when he drops the item
or moves it to another inventory
serene sigil
yes, but those are a lot of events to listen to, its i think better if i just scan the entire inventory
iron glade
Then maybe a task timer that checks that every minute or so?
and some boolean hadItemOnLastCheck or smth like that
so that you don't keep adding 100 xp levels
serene sigil
nvm
u dont understand
the egg is like visual levels, so if u have it u get 100levels and if not, u dont have those 100 levels
