Spoonfeed a newbie for a day and they'll come back with more questions. Teach them to find their own answers and you'll both be better off: you won't get stuck answering the easy questions and they'll be much more productive than before.

Stuff like what
Stuff that’s not specifically dependent on spigot or another api
glossy laurel
I can... do that ig?
hybrid turret
Stuff like what
abstraction, inheritance just plain new objects.
very basic java stuff that already provides a lot of functionality
worthy yarrow
For example in java there’s no “player” object, this is apart of nms code which abstracted to bukkit which abstracted to spigot and so on, that being said in regular java you could do player player = bukkit.getPlayer
You’d have to define what a player object is yourself

"Non static method cannot be referenced from a static context"
this is what I was doing when I just learnt java

Either way it seems clear to me that you’re not knowledgeable enough to use an api, so that’s why I told you to learn java… it wasn’t to be taken offensively but again that wouldn’t be my issue

A clipboard is basically just "pastable content"
worthy yarrow
I don’t think even that would help
echo basalt
Worldedit is platform-agnostic which means that they just write a huge core and then make little adapters for each platform
Which is slightly ass because you gotta convert everything to their format
worthy yarrow
You’d have to explain to him what a clipboard is doing under the hood and how to use it and in which ways you shouldn’t use it etc, but that comes with doing it yourself
Ie: teaching the man to fish rather than feeding him for a day

no you don't lmao just explain how it's used and if he wants to learn he can look at the code

It’s not that I mean to come off rude or offensive it’s just hard after so many times trying to explain “simple” stuff to someone and they still don’t get it makes me think they just don’t know anything (.) which is a flaw of mine for sure and should be worked on but at the same time I’d still rather put a little effort in being when I told you to learn more java or read documentation

Hi, any ideas about having different tick speeds for different worlds/players? The original vanilla command (/tick rate 20) is global.
There are no useful functions about tick rate in the paper documentation website. Would NMS somehow work? (I have no idea)
Some background you probaly don't care about: This is for a tas pvp server, where players can choose the tick rate to battle in. I have a decent amount of coding experience, but I'm a bit rusty when it comes to minecraft plugins

@glossy laurel a solid solution is to just look at how worldedit does it

but doesnt spigot also just interact with the internals?
or bukkit
or paper
or any api

For example I'm working on a bedrock server. The Geyser API doesn't expose anything about custom entities or packets, so I gotta mess with the internals and inject stuff into the player's connection to then listen to packets and decode them with the same library that geyser does

it's just a location but without a world

You should separate your concerns. Your GUIs should def not be Listeners.

Write a GuiManager class which maps Inventories to your custom implementation.

but fair to say its api misuse
a good api misuse

GUI gui = guiMap.get(inv);

I can imagine you're going to end up overwriting your registration if two players open the same inventory
But that won't be a problem if you use the InventoryView
Which probably isn't a huge issue if your GUI instance is constant, but if it contains any state, you might end up losing that state and mangling state between two separate players with the same GUI open at the same time

The memory address is used as hash if i understood it correctly
no
lost matrix
Waiting for a followup
slender elbow
thatt might have been the case, like, a million years ago
but also, like, the gc is free to move objects around in memory and such so it's just not reliable
java 8 javadoc says "This is typically implemented by converting the internal address of the object into an integer", so it's some kind of address to identify the object, but those docs are long outdated anyway

Who said the GC could move my stuff :O
It may look like a mess but I know where everything is!

Currently hunting it down. src/java.base/share/native/libjava/System.c

Not really insightful...

I believe there was a motion to offer a 64-bit variant of hashCode

static inline intptr_t get_next_hash(Thread* current, oop obj) {
intptr_t value = 0;
if (hashCode == 0) {
value = os::random();
} else if (hashCode == 1) {
intptr_t addr_bits = cast_from_oop<intptr_t>(obj) >> 3;
value = addr_bits ^ (addr_bits >> 5) ^ GVars.stw_random;
} else if (hashCode == 2) {
value = 1; // for sensitivity testing
} else if (hashCode == 3) {
value = ++GVars.hc_sequence;
} else if (hashCode == 4) {
value = cast_from_oop<intptr_t>(obj);
} else {
unsigned t = current->_hashStateX;
t ^= (t << 11);
current->_hashStateX = current->_hashStateY;
current->_hashStateY = current->_hashStateZ;
current->_hashStateZ = current->_hashStateW;
unsigned v = current->_hashStateW;
v = (v ^ (v >> 19)) ^ (t ^ (t >> 8));
current->_hashStateW = v;
value = v;
}
So it falls back to some... pseudo random number generation. And it looks like that is added to an objects header.

That would just lead to collisions
slender elbow
they take into account hash collisions
lost matrix
So they would be O(n) all the time
young knoll
Peak efficiency
slender elbow
technically not necessarily
for a HashMap, if the class implements Comparable on itself, it'll do a tree instead of a list
lost matrix
In theory there is an implementation where a hash bucket can be operated as a rb tree with sub-buckets
Yeah you sniped me
The object doesnt need to implement comparable even. You can use the hashCode int to build a tree.
Collision doesnt mean the hashCodes are identical.
slender elbow
until it does :Clueless:
lost matrix
Well in that case they are. Which would result in a tree with one bucket, where everything ends up being compared in O(n) again
Wait, the jvm doesnt impl trees using the hashCode right now?
Is this the time where i propose a JEP

If you have a question, please just ask it. Don't look for staff or topic experts. Don't ask to ask or ask if people are awake or available. Just ask the question to the channel straight out, and wait patiently for a reply. Make sure you use the right channel regarding the topic of your question.

Sadly, JNI is needed for that which has quite the terrible performance so I ended up going with a less performant solution instead

So considering I want to map players to roles within the islandImpl, would you guys say it is dumb to also reference an island role in the playerData as well?
I already hold their island in playerdata which you could derive the role from

tf is that wallpaper
worthy yarrow
I found it on wallpaperengine actually kek
echo basalt
do you really need the members set if you have the roles map

IMO you need to break it down into classes. Doubt there's a good reason to store roles on the player data itself

why would you want to make your code even more unreadable

Why touch grass when you can look at fake grass
worthy yarrow
do you really need the members set if you have the roles map
That is a fair point, haven't implemented playerRoles yet so, that was what I had before
Also given I go with playerRoles style, I feel like I would put every person's uuid in every island's playerRoles map as to account for visitors (and it's respective role)
I'm not sure how I feel about this but haven't really thought about it too much, so any ideas on how to handle this?
