ScoreboardManager sm = Bukkit.getScoreboardManager();
Scoreboard board = sm.getMainScoreboard();
team = board.registerNewTeam(team_name);
team.setOption(Team.Option.COLLISION_RULE, Team.OptionStatus.NEVER);
team.addEntry(player.getName());
And i add both players

Sorry for another question, but is there a way to change block properties from plugin like using the debug stick?

Looks fine. You should never collide with any team
gusty bough
But it doesn't work and idk why

How do i add a item to an inventory?
Inventory inv = Bukkit.getServer().createInventory(null, 27, "§9Links").addItem(DiscordItem.Discord)
inv.addItem
quaint mantle
ok ty
eternal oxide
addItem doesn;t return an Inventory
quaint mantle
alr
anybody knows
whats wrong
i tried also
when i open the inv
the items arent there
eternal oxide
yeah, COMMAND isn;t a possible ItemStack
young knoll
Those are legacy materials
wraith rapids
COMMAND is the old material name for the command block yeah
torn oyster
but i want it like this
no i literally have a scoreboard system for this
Objective h2;

h2 = board.registerNewObjective("showhealth2", "health");
h2.setDisplaySlot(DisplaySlot.PLAYER_LIST);
h2.setDisplayName("" + ChatColor.YELLOW);
} else {

how do i do it

I've multiples identical ItemStack (same name, same lore, same Material, ..) so they have the same hashCode. Is there an hidden tag i can used to get differents hashcode between my items stack please (to be able to use .removeItem to delete the specific item) ?
chrome beacon
how do i do it
You might have to do some reflection. We don't know since we don't use ancient versions
Decompile some classes and look around
wraith rapids
no, not without making the items unstackable
if unstackable items are fine, add a UUID into the persistent data container of the ItemMeta of that item
and that will make the stack unique
it won't stack, but you can target it specifically with removeItem and similar
spring river
if unstackable items are fine, add a UUID into the persistent data container of ...
that's what i was thinking yep
but where can I add something into data container of ItemMeta ?

Was there a recent update/change to Scoreboards? It seems registering teams to the Main scoreboard now throws an already registered error
wasn;t happening a couple of days ago
cold field
How can you abuse?
sullen marlin
Nope, no changes in months if not years
eternal oxide
odd but ok
gusty bough
even with the code you gave me i cannot deactivate collisions between players x)
eternal oxide
Odd. You saw it working on the demo server I ran up
eternal oxide
enable?
eternal oxide
I see no entry in spigot yml for collisons
wraith rapids
that's on paper
which does it through teams as well
because player collisions are client side
and the only way to disable them is to set the players in teams with the collision rule off
eternal oxide
So default with Spigot collisions are default on
gusty bough
With teams i can achieve no collisions between me and other entities (but not others players)
like me and a villager
eternal oxide
Well I'm afraid I can;t test for you at the moment. I seem to have broken team registration on the Main scoreboard somehow
gusty bough
Do you have same bug?
eternal oxide
No
eternal oxide
I'm having an issue registering any team on the Main scoreboard. It complains that the team name is already registered
Which has me stumped as I've changed no code I can think of
very odd. It was working when I tested collisions now no scoreboard team registration works
well, no registration on the Main board
gusty bough
Honestly these teams systems are fucked
eternal oxide
yep, they persist through server starts

that's a rather complex algorithm

Yeah I know lol
wraith rapids
logarithms and shit
side length 1 spans index 0, side length 2 spans indices 1 through 4, side length 3 spans indices 5 through 8, side length 4 spans indices 9 through 16, etc
or actually looking at it that's totally wrong
could just find it iteratively i guess
find the floor of the square root of the index and you'll get the side length, then check whether you're past halfway to the square of the next integer
then xor with side length % 2
and throw a few more xors and %2's at it and you'll probably get there

The real question should be, Why do you want to trace this pattern?

rotund pond
Hello guys !
I'm trying to create more complete configuration files than usual to me, and I'm having a problem.
How can I get all the sections back?
In my example, it will be all "whiteGlassPlane", "lightBlueGlassPane" etc ...
I want these sections to have a user configurable name, and this is where my problem lies: /
other than brute force and testing for all characters ... xD
Thank you for your time
wraith rapids
get the section and call getKeys on it
spare mason
in the chat say spawneando un whiter skeleton no spawn any
wraith rapids
it'll return a list of all the sub-sections and keys in it
f.e if you get the decoration section, and then call getKeys on it, you'd get the elements you listed in your example
rotund pond
Ah !
Keys !!
That's what i was looking for, but i didn't know these were called "keys"
Thank you dude ♥
Last question: the method is getKeys(boolean arg) ... What is this boolean ?
wraith rapids
whether for the get operation to be shallow or deep
getKeys(true) will return every key and every key of every sub section and so on
so it'd give you whiteGlassPane, whiteGlassPane.material, whiteGlassPane.name, and so on
getKeys(false) only gets the keys in the level immediately below
rotund pond
OH Well, i'll use getKeys(false) so xD
Thank you again 🙂 ♥

wraith rapids
you aren't setting it to null
quaint mantle
?
wraith rapids
you are setting everything under it to null
you are setting spawn.x to null; set spawn to null

setting everything in a section null results in an empty section
setting the section to null results in it being removed altogether

hollow river
hey so i'm a little conflicted on what to do here. i want to create custom quests but can't decide on using some file containing quest data, or to make a separate class for each quest (so that way i can heavily customize it and make quests more unique, trigger some animation, do something to the player etc. which i wouldn't be able to do with just loading in a quest form a config file) so would creating a separate class for each quest be the best option here?
this would eventually also translate to custom npc's who do different things on interaction/death, custom mobs, custom items etc.
i just don't know if ending up with 60+~ quest class files would be good practice
earnest junco
hey so i'm a little conflicted on what to do here. i want to create custom quest...
Hard coding is easier short term, but allowing configuration through files is going to please whoever you do that for much more and will cost you less work later on.
You could allow different actions like BREAK, KILL, etc. and load the quests through that.
IMO, configurable is always better. You could still hard code the extremely complex quests and abstract generic quests down to aforementioned actions.

hollow river
Hard coding is easier short term, but allowing configuration through files is go...
yeah my approach with quest classes would be to make the process of making a new quest as easy as possible through code, most methods being in the main Quest class already so you can use already existing functionality like killing 5 types of a mob. i think i'll try and give classes for each quest a shot because i love the freedom in that approach. im also making the plugin just for myself as a learning opportunity to slowly make a big rpg plugin (kinda like wynncraft in the end) thanks for the advice!
stoic iris
How would I call an event if someone gets an advancement, and how check if a specific advancement is gained? I can't find the enum in the JavaDoc, if it even is in it.
candid galleon
well an event already exists for that @stoic iris
you wouldn't have to call it, it's already called
stoic iris
so how would I figure out what specific advancement was achieved in an event handler?
summer scroll
is sending titles thread-safe? means that i can run it in an async task
candid galleon
try it and see
stoic iris
if(event.getAdvancement() == x) what do I put for x?
drowsy helm
probably an enum
stoic iris
yeah I can't find where the list of enums are
candid galleon
it looks like Advancement extends Keyed, so you can get the name of the advancement with Advancement#getKey().getKey()

struggling a little bit with some logic im trying to get figured out. im essentially trying to create an additional bar similar to the food bar in vanilla minecraft using custom icons via a resourcepack put into the player's actionbar with some negative space trickery to place it in the right spot.
showing it to the player I got down but the problem I am having is a way to take a percentage of how full the bar should be and create the string full of the icons (full, half full, and empty) in order to create the full bar. I got pretty far but 1. I feel I am severely over complicating it and 2. its not working as intended. it is always showing at least 1 half-full icon even when it doesnt need to (ex. half of the bar being full and the other half being empty bars)
heres my code so far:
so the //create bar part is where the issue lies
im essentially running a loop that runs 10 times (one for each bar) and checking whether that bar should be full, half full, or empty depending on the percent fullness of the entire bar
once I get to the part of the bar that is half full or entirely empty, I set the rest of the slots to empty icons and end the loop
the thing is I dont think it is reaching a point where it detects the slot is entirely empty for some reason
something must be wrong with my math
craggy dawn
ok, I just need a bit of help, I need to copy a world, but whenever I copy it, it just creates a super flat world. here is my code
WorldCreator wc = new WorldCreator("" + id);
World copy = Bukkit.getWorld("island-template");
wc.copy(copy);
w = wc.createWorld();
anyone know how I can fix this?
OHHHHH I just relized, WorldCreator.copy() only copies the settings, not the world, how can I accomplish this?
is the event triggering?
are you getting an error?
also wait.. are you casting event to player?
oh ok
yeah ok

Still an unsafe cast

dense goblet
whyyy is custom RecipeChoice not supported .-.
young knoll
What
dense goblet
if you make a class which implements RecipeChoice, it can't actually be used when registering recipes
young knoll
Why are you making a class that implements recipeChoice
dense goblet
because I have custom items that can be smelted
young knoll
dense goblet
that will not work
young knoll
Why not
dense goblet
because my custom items are not simple and their recipes may not be either
young knoll
Doesn't matter?
dense goblet
yes
young knoll
It matches any custom item
dense goblet
it would not work for a scenario like:
an iron ingot with PDC tag "type" = "ingotSilver" and tag "quality" >= 0.8
young knoll
Well the type part would work
dense goblet
yes but that is the easy type
young knoll
You aren't supposed to implement bukkit interfaces, but it should work in theory
dense goblet
I already have custom crafting system, just gotta hook into the furnace
it unfortunately doesnt work
gives an error
and is labelled as illegal to implement in the docs
it doesnt make anything impossible but I gotta do workarounds to check if the furnace recipe is doing a vanilla recipe or one of my custom ones
because also you can't get the recipe's NamespacedKey from FurnaceSmeltEvent
young knoll
dense goblet
okay I see why its unsupported
if either that or the key thing worked it would be okay but unfortunately neither do so workarounds it is

https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/io/InputStream.html#readAllBytes() is my fav new method, it's less work for me and it is like 100x faster than a while-loop on https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/io/InputStream.html#read()
quiet ice
I recommend to, especially when dealing with (N-)IO

It will lead to better performance if you compile it natively at newer versions, even if it will be minimal

What I mean is. How bungee is able to redirect a player to another server?
cold field
More functions, elaborate
Does it exists something that does the samething but better? I saw that several networks use something called waterfall
eternal oxide
Thats its job, its a proxy.
cold field
idk, why some network prefer not to usee bungee
ivory sleet
What
eternal oxide
I use Eclipse, Conclue uses InteliJ
ivory sleet
Yes I mean some servers consist of just one server
Then using a proxy is quite pointless
Most networks use bungeecord or some fork of it assuming you want to have a proxy server for your backend servers
molten hearth
idk, why some network prefer not to usee bungee
Waterfall has more patches than bungee
eternal oxide
Waterfall has more patches than bungee
Means nothing. Perhaps they made hundreds of typos they had to fix. At least list something constructive to show one is better than the other.
molten hearth
I'd still choose waterfall if they only had typo fixes
ivory sleet
Your choice
cold field
I need to know how that works... Can you guys link me some website?
eternal oxide
How what works?
cold field
A proxy
eternal oxide
eternal oxide
and DON'T stop reading after its up and running.
cold field
soo. bunge is the same thing as a proxy?
eternal oxide
If you fail to read the Post-Installation section you will be exposed to every hacker in the universe.
cold field
ok, i'm going to read
quiet ice
if that is the case, why isn't that the default?
quiet ice
makes sense
cold field
Guys, i read something but I've questions.. For instance, if the proxy does an intermediary job how can the final server knows the user ip?
And, if I host something and all the user traffic goes through the proxy server and that server is a low performance server this will cause lag, right?
drowsy helm
I don't think bungee allows multiple proxies
wait no i lied it does
i would say one powerful proxy
not necessary to have multiple until you reach the tens of thousands of players
cold field
nutil?
drowsy helm
all the proxy does it forward packets, it doesn't require a super beefy server anyway
cold field
what can it be the security issues? That a user can access directly the server without using the proxy?
drowsy helm
well a proxy is more safe
you only have to expose the proxy's port
rather than exposing all the servers' ports
cold field
no what I mean is, what are the security issues if I use a proxy
drowsy helm
theres none really
cold field
oh
cold field
mh..
drowsy helm
but theres not much you can do anyway, would happen with a regular server
cold field
only if that proxy server gets ddosed
The hosting should take care of it, right?
cold field
With multiple proxies I can mitigate that, right?
drowsy helm
to a degree yes
but still it's not super necessary
even networks with 10k concurrent players use 1 proxy
they are super robust
cold field
so they have a powerful ddos protection
drowsy helm
yeah
most dedi hosts like OVH, SYS, hertzinger etc have ddos protection
cloudflare, if you use a domain
cold field
Mh, I need to make a school project about that. What should I use? One proxy or many?
cold field
I don't really need to take care of it. I just need to design an architecture

many proxies also mean your client is going to have to connect from one of many ports
unless you have a loadbalancer
which is another type of proxy
not minecraft related
cold field
I think hypixel make uses of a "loadbalancer", right?
cold field
mh, interesting.
This is my final exam of secondary school. I need to make something good
drowsy helm
whats the exam exactly
cold field
It is of my choice
I'm creating a minecraft server
XD
All my classmates have done websites, but I wanted to do something else
so I'm here
ahahah
drowsy helm
fair call
cold field
I don't really need to setup a system like the hypixel one. I need only to design it. Do you think that it would more appreciated a system like the hypixel one or a single proxy?
proper notch
hypixel will 100% have way more than 10 proxies btw
also for using MC through cloudflare, you'd have to pay for spectrum.
cold field
spectrum?
quiet ice
premium cf

Mhm. Their services for websites are free, but for other services it's paid

Unless ur a big server, ovh ddos prot is enough.
I can't remember what Hetzner's ddos prot is like but off the top of my head, it's not great
cold field
I don't really need to setup a system like the hypixel one. I need only to desig...
what do you think about that?
proper notch
Having more proxies is always gonna be better if you have say more than 500 people. It gives you redundancy, better performance and also means you hopefully designed your system out of the box to be scalable.
And if you can horizontally scale, that's a huge benefit over vertically scaling.
And in this modern day, having the skills to develop horizontally scaled systems is important to so many things.
proper notch
Horizontal scaling = being able to add more systems
Vertical scaling = just making the existing system more powerful
cold field
oh
ok
any suggestion to gets started with that. I need to know what a load balancer is and after that what?
proper notch
E.g google won't just have 1 big really powerful computer. They've designed their systems to use tens of thousands or hundreds of thousands of systems that can all coordinate with each other.
cold field
Mhmh
proper notch
same as hypixel I assume. They'll have their proxies spread over many servers
Your loadbalancer will likely depend on what other softwares you use. I've only done it within kubernetes, so I have no idea about loadbalancers that are good outside of that
Just know when you're doing stuff with multiple proxies, loadbalancers, etc.. you're going to be using a lot of APIs to make everything communicate, so the structure of it can be quite big. If it's too much, just abandon one part of it.
cold field
Just know when you're doing stuff with multiple proxies, loadbalancers, etc.. yo...
do you mean abandon the project?
proper notch
Nah just like, abandon a part of the structure. If it's too complex, maybe use a less advanced loadbalancing system that doesn't account for player counts. Or maybe don't bother having the multi-proxy system.
cold field
Oh k
proper notch
stuff like this when doing it for the first time will take a while to find good structures, good loadbalancers, etc..

Hi, I want to ask a question about RAM usage on minecraft server, I have 75 Active player and around 60+ Plugins, and I want to use 12gigs of ram for the server, do you think it will be enough? (my Server is a Survival SMP Server, so there's a chunk load, etc)

I've read something about "Minecraft Custom Startup" with Aikar Flags, do you think it helps for a minecraft server like mine?

unless you are doing some strange things, correct startup flags always help

How can I change mob's facing?
example: mob is looking north. i want change it to south
wraith rapids
rotate it
eternal oxide
setDirection(BlockFace.SOUTH.getDirection()) on the location
quaint mantle
Thanks, but setDirection in Entity not exists
eternal oxide
on Location
wraith rapids
you'll probably have to get the location, set the location's direction, and then set the location
quaint mantle

Should I use world edit or fawe? I know that fawe make use of async thread but some people told me that in the past fawe has caused world currption.
Or any other plugin
young knoll
Not anymore
FAWE was pretty good back in 1.12
Not sure how it is now
If you aren’t changing massive amounts of blocks regular worldedit is probably fine
wraith rapids
fawe is short for fast async world exception
sleek pond
lol
wraith rapids
i'm a citizen of paper
access to their memes is my birthright
supposedly fawe isn't as batshit unstable now as it was at some point, but the only guy i've seen defending it in recent memory is its author, so I'd take it with a grain of salt
quaint mantle
Hey spigot! I'm setting mob's facing. here's my code:
entity.getLocation().setDirection(new Vector(?, ?, ?));
Where should yaw or pitch go in '?'.
wraith rapids
read the documentation
i'm pretty sure there's a method somewhere that shits out a vector from a given yaw and pitch
quaint mantle
ya, i already read the doc. hmm
wraith rapids
do you absolutely need pitch and yaw?
sleek pond
i'm pretty sure there's a method somewhere that shits out a vector from a given ...
lmao what
sleek pond
?
wraith rapids
you don't put it in the vector
quaint mantle
hmm?
sleek pond
what are you talking about
wraith rapids
a vector represents a direction with 3 values
sleek pond
please make coherent sentences
quaint mantle
Hey spigot! I'm setting mob's facing. here's my code:
```
entity.getLocation()....
here
wraith rapids
distance towards X
distance towards Y
distance towards Z
directly up would be 0,1,0
directly south would be 0,0,-1
or would that be 0,0,1
i don't fucking remember
sleek pond
positive is usually up, right and forward
quaint mantle
distance towards X
hmm, how can I set like that? It says it needs a vector.
sleek pond
jesus fuck
wraith rapids
you instantiate the vector
sleek pond
new Vector(distance towards X, 0, 0);
wraith rapids
with the fucking constructor
quaint mantle
yap
wraith rapids
if there's no method to actually shit out a corresponding vector for you, you could always rotate an unit vector around the corresponding axes with the pitch and yaw you need
but you probably don't actually need pitch and yaw
quaint mantle
i understood ty
quaint mantle
or would that be 0,0,1
im sorry, but why it's 0,0,1?
south's yaw is 0
and pitch is 0
quaint mantle
What distance
wraith rapids
of the direction
wraith rapids
0,0,1 -> 1 block to the south
sleek pond
do you know the coordinate plane?
sleek pond
0,0,1 -> 1 block to the south
shut
wraith rapids
0,1,1 -> 1 block to the south, 1 block up
quaint mantle
do you know the coordinate plane?
ya
quaint mantle
your entityies head is at 0, 0, 0
sorry, but what do you mean?
yaw, pitch, and what
wraith rapids
lmao
quaint mantle
ah
sleek pond
coordinates
quaint mantle
but it's direction
wraith rapids
wraith rapids
it's a 3D direction, yes; that is why there are 3 components
1 component for each dimension
X,Y and Z
quiet ice
Vectors are location, direction & force
wraith rapids
or your mom
quiet ice
Color?
wraith rapids
well
quaint mantle
wait i'll draw a picture
wraith rapids
that it has 3 numbers is an arbitrary distinction
sleek pond
usually it is an arrow ferom 0, 0, 0 connecting your point

A Java.utils.Vector vector is a list that is synchronized (i. e. thread safe but not really)
wraith rapids
the vector list is ancient trash
sleek pond
it's a good way to understand
thinking of a vector as just one thing is very limiting
wraith rapids
has anyone brought in the actual definition yet
direction and magnitude and that shit
quiet ice
Yeah, the vector list should be deprecated; I know someone that is overusing it
sleek pond
Yeah, the vector list should be deprecated; I know someone that is overusing it
who is that
quiet ice
Vectors are location, direction & force
so this
quaint mantle
is it right?
sleek pond
yes
wraith rapids
well it has the word direction in it so
quiet ice
who is that
A game developer of some java game noone knows of
wraith rapids
imagine that the entity's head is at the center of the world
at X Y Z coordinates of 0 0 0
quaint mantle
Ahh
wraith rapids
now, imagine that the entity is looking at a block
if this block is at X Y Z 0, 1, 0
young knoll
I mean you can set the pitch and yaw directly too, if you wanted to
wraith rapids
it will be looking directly upwards
sleek pond
I mean you can set the pitch and yaw directly too, if you wanted to
only location
wraith rapids
because the block is one block above it, directly above it
sleek pond
not vector
wraith rapids
if the block is at 0,0,1, the entity will be looking directly south
quaint mantle
Ahh
wraith rapids
because the block is 1 block to the south from the entity's head
young knoll
Make a location, set pitch and yaw, tp to location
quaint mantle
yaa
sleek pond
hes trying to make an entity look somewhere
wraith rapids
if the block is at 0,1,1, the entity will be looking directly south and 45 degrees up
because the block is 1 block to the south and 1 block up
wraith rapids
this would represent a yaw of 0 and pitch of 45, if I remember my numbers correctly
wraith rapids
myeah
sleek pond
and .setPitch
quaint mantle
ah
wraith rapids
you'll have to set it back afterwards
like I said at the very beginning of this conversation
young knoll
Pretty sure those are void methods
wraith rapids
that'd be quite annoying
wraith rapids
so that's probably the case
wraith rapids
although I do remember Locations being super fucking arbitrary when it comes to returning itself or a clone
young knoll
They are
sleek pond
in what world would you want a clone
wraith rapids
every fucking time I work with them I have to go look at the source to check whether I need to defensive clone or not
some of the methods return a clone
others don't
and it's not fucking documented

Is it ok to call PlayerMoveEvent, or should I just make a BukkitRunnable every tick?
wraith rapids
you probably mean listen to move event rather than call it
depends
the player can move multiple times a tick
so if you need super high precision, use the event
wraith rapids
if the code is lightweight, the listener is fine
woeful crescent
It's adding a Location to an ArrayList in a HashMap if the block there isn't air, and if the list doesn't contain the Location.
wraith rapids
sounds like a kind of poor implementation for what you're doing, but it's lightweight
well, cpu wise, anyway
cold field
why world edit doesn't maintain state of the blocks????
wraith rapids
are you on the right version
woeful crescent

Poor implementation?
wraith rapids
it'll yeet the actual block data if there's a version mismatch
woeful crescent
What would be a better implementation?
cold field
it'll yeet the actual block data if there's a version mismatch
Oh, ok thanks
wraith rapids
something that doesn't involve storing potentially tens of thousands or millions of block locations in contiguous arrays in memory forever
woeful crescent
Nah, I don't mean that
it resets on death
it's a thing that encourages players in an ffa pvp game to move around more
a class upgrade called Traveller
wraith rapids
mmmmaybe then but there are still some issues
for example, you probably don't want to add more travelled distance if the player is standing still
which would mean making sure the block has changed since
you probably also don't want to accumulate distance if the player moves between the same 2 blocks repeatedly
that is, each block should probably only count once, or maybe once per some timespan
this would be better represented by a Set than a List
cold field
@wraith rapids Do you know why when a player join into the server and I send a playerInfo packet and a playerSpawnPacket to him right when he has joined or within 20ticks the skin of the fake player isn't shown?
wraith rapids
dunno, i don't do skins
if the skinsrestorer discord has a dev channel you could ask there
cold field
thanks for the tip
woeful crescent
that is, each block should probably only count once, or maybe once per some time...
That's why I'm using a list of locations instead of just an integer map
to check if the player has already been there
wraith rapids
yes, well, see, the contains check of a List isn't very fast
if you have 1000 locations in the list, you'll have to go through every last one of them with every .contains check
in comparison, a Set ideally only does one or two comparisons regardless of its size
you speak of a "unique blocks travelled" metric
therefore the data set that you use should emphasize on that "unique" aspect
cold field
multiverse-core should really implement tab-completation...
wraith rapids
Lists can contain the same element multiple times
the elements of a list aren't necessarily unique
the elements of a Set, however, are unique in that set
an element either is in the set, or it is not in the set
this represents what you are doing much better
woeful crescent
Yeah, I was gonna change it to a set
wraith rapids
to further minmax things you could create an immutable blocklocation class that caches its hashcode for better hashset performance and smaller memory footprint
but that could be deemed premature optimization
woeful crescent
Also, should I be using a HashMap<UUID, Set<Location>> to store it uniquely for each player or is there a better option?
wraith rapids
which is apparently a massive fucking sin
nested collections and maps are sort of a code smell, generally it'd be prefered to have a Map<UUID, PlayerData> map, and have the PlayerData class hold onto the Set<Location> and whatever other data you might store for your players
thorny bridge

Will adding a duplicate to a HashSet throw an exception, or just not add it?
Nvm
cold field
@wraith rapids can't find the right version in which the schem was saved... If I use MCEDIT is the state mantained?
woeful crescent
Any better way to do this? (checks set size for player attribute modifier, resets on death)
public static final HashMap<UUID, Set<Block>> travelled = new HashMap<>();
@EventHandler
public void blockGet(PlayerMoveEvent e){
UUID pUUID = e.getPlayer().getUniqueId();
try{
Set<Block> locSet = travelled.get(pUUID);
Block block = e.getTo().getBlock();
locSet.add(block);
}catch(NullPointerException addToMap){
travelled.put(pUUID, new HashSet<>());
}
}```don't catch nullpointerexception
woeful crescent
What should I do instead?
wraith rapids
make sure you don't cause a nullpointerexception to be thrown
woeful crescent
does catching exceptions slow it down?
wraith rapids
yes
wraith rapids
significantly
and it is bad practice to catch instead of check
you should stop it from exploding before it explodes
Map also defines a method that computes a value for the key if it isn't present yet

hey, wildcard permissions need to be coded by the plugin itself, right?
wraith rapids
depends on your definition of plugin and wildcard permissions
are you writing a permission plugin?
lost depot
non-permission plugin
wraith rapids
the permission plugin handles wildcard permissions if it supports them
that is, your plugin can check for myplugin.x
lost depot
i expect the server owner to use something like luckperms etc.
wraith rapids
and if a player has myplugin.*
then the permission plugin, if it supports wildcard permissions, will return true for the myplugin.x query
thorny bridge
sharpXX.addEnchantment(Enchantment.DAMAGE_ALL, 20,true);
didnt work
wraith rapids
if that's what you mean by wildcard permissions, no, you don't need to handle them yourself
they're handled by the perms plugin
lost depot
but if they're not, they wont work, right?
wraith rapids
myes
lost depot
k, thx
wraith rapids
if you want to support people who don't use wildcard compatible perms plugins, define a root permission in your plugin.yml
and set all of the other permissions as children of that node
lost depot
oh that makes sense
wraith rapids
then, giving that root node, like myplugin.all will give the player all of its children, giving them access to all of the things
it's usually also nice if you provide group nodes like myplugin.admin and myplugin.player to group together different permissions that are probably used by different groups of users, like admins and regular users
that way the end user only has to give those nodes instead of going through a list of 3000 permission nodes and adding them individually
