for example i have 3 events that all relate to a custom gui im making
#help-development
torpid sapphire
and 4 events that remove mending from the game
so i split all of those into their separate handlers?
tender shard
if you have the PlayerInteractEvent twice, and they both start with the same 10 different lines for checking (e.g. was a block clicked, is the player OP, does the player have a certain item, ...) then I'd have one eventhandler and then decide which of my other methods to call
if however both eventhandlers are totally different, I'd just use two event handlers
torpid sapphire
well i dont have any duplicate events yet
tender shard
@EventHandler
public void onInteract(PlayerInteractEvent event) {
// 10 lines of if statements that doLeftClickThing and doRightClickThing would have in common...
// ...
if(event.getAction() == Action.LEFT_CLICK_AIR || event.getAction() == Action.LEFT_CLICK_BLOCK) {
doLeftClickThing(event);
} else if(event.getAction() == Action.RIGHT_CLICK_AIR || event.getAction() == Action.RIGHT_CLICK_BLOCK) {
doRightClickThing(event);
}
}
yea i see
tender shard
```java
@EventHandler
public void onInteract(PlayerInteractEvent event) ...
this might make sense if you have many checks before the first if that would otherwise be "duplicated" in both things
but if they do TOTALLY different things, e.g. one InteractEvent is to check whether a block was clicked, the other is to check whether a player uses some very special item, then just make two event handlers
in the end, it doesn't really matter. unless you register A SHIT TON of event handlers since ofc if the HandlerList gets very long, this is not very good for the server performance
but I doubt that you wanted to register 5000 eventhandlers in one plugin
torpid sapphire

my minecraft plugin is not gonna profit from a single saved allocation
and it might take me a few minutes to do
which could be spent doing something more productive
when doing some embedded low level stuff its definitely important
wet breach
even in high level it matters
that one extra allocation, means another object for the JVM keep track of, another pointer being used, space in the stack being used, and now the GC at some point might need to handle it
but is it really going to matter for a small plugin, most likely not. But it does matter on systems where they have like thousands of players though
tender shard
GC? The listener is only created once
wet breach
because mass amounts of resources are already spent for those players
tender shard
GC? The listener is only created once
And then stays there for ever
wet breach
GC? The listener is only created once
that wasn't the point I was making
tender shard
Okay but we only talked about listeners
torpid sapphire
but it really doesnt make a noticable difference on modern hardware
wet breach
ok, my point was that all objects whether small or not do have an impact, just the impact is not seen until you hit a certain point
torpid sapphire
exactly
wet breach
so, yes 1 extra allocation of an object can make a difference, just doesn't for small plugins
torpid sapphire
exactly my point
what i meant was that its not worth it spending 10 mins on optimizing a single allocation away when you could spend that time doing other stuff
tender shard
I sometimes even listen to the same event for every priority separately lol
wet breach
what i meant was that its not worth it spending 10 mins on optimizing a single a...
exactly this, however if you are mostly done and that is really all you have, then I say go for it
because while small plugins generally don't see such benefits, if you get enough small plugins together
then it does matter
this applies if you are making public plugins
because what some devs forget, your plugin isn't the only one going to be on the server lol
torpid sapphire
I sometimes even listen to the same event for every priority separately lol
what do the priorities even do?
tender shard
LOWEST gets called first, HIGHEST second latest and MONITOR is latest
e.g. imagine you wanna check if a player is trying to place a block on NORMAL priority
a plugin on LOWEST might have already cancelled it
so on normal, you can just ignore it if the event was already cancelled on LOWEST
torpid sapphire
how does it handle multiple handlers on the same level
tender shard
the first registered listener gets it first
torpid sapphire
fair
tender shard
the HandlerList is basically nothing more than a list of methods to call, ordered by priority, or ordered by "time of registering" when same priority
okay in fact it's an EnumMap, but still, same idea

In this use case I'm assuming you'd never want another instance of DataStorage under any circumstances thus it being singleton

depends why / how you are using the data
hasty prawn
The only way you can cancel an event is within the handlers themselves, anything async and the event would be finished by the time you went to cancel it.
wind tulip
Well as far as I know you can't cancel events async at all
So the origin of the issue is how cancelling events works
(Event happens in mc world)
(Call event method)
(If event was not cancelled, Minecraft Stuff here)
async threads happen after the event method, so that's why this is a problem
what I'm asking is if I can run an async thread on the same tick instead of scheduling them for the next
if not with the bukkit scheduler then with my own or any alternative
hasty prawn
Uh, I doubt it.
fresh timber
im using it for a command /particles and in particles if u use the cmd it adds a ur user and a string of the particle u used in an arg in a hashmap and in another class listener it makes particles at ur feet if the hashmap contains that key with that value when u walk

That's not really how async works afaik

The bukkit scheduler just waits for the next tick and executes the runnable there

ahhh I see okay so you'd want to make a cache class kinda like I displayed above you could also use DI which is what i'd recommend for a beginner. Than on quit make sure you save that data to a file and load it up on start so when players rejoin after server shuts down that data is still there
you should also make it more advanced but you can worry more about that later

Well, no. When you make an async task the Thread you created it on sole job is to ONLY make the task, not run anything inside it.
Once that async thread is created, that thread continues on its merry way to do whatever else it needs to do. The computer then decides when that async Thread actually runs what is inside it.

how to check if an entity is in the end?

how to check if an entity is in the end?
entity.getWorld().getName().equals("world_the_end") is probably the most simple way

how to check if an entity is in the end?
entity.getWorld().getName().equals("world_the_end")
or at least
torn oyster
entity.getWorld().getName().equals("world_the_end")
3rd times the charm
harsh totem
entity.getWorld().getName().equals("world_the_end") is probably the most simple ...
but if the world isn't named like this?
torn oyster
but if the world isn't named like this?
them check dimension type or something like that
fluid river
entity.getWorld().equals(plugin.getServer().getWorldConrainer().get(2));
drowsy helm
entity.getWorld().getEnvironment() == World.Environment.THE_END
torn oyster
entity.getWorld().getEnvironment() == World.Environment.THE_END
better

if end is world 2
harsh totem
entity.getWorld().getEnvironment() == World.Environment.THE_END
thx
fluid river
entity.getWorld().getEnvironment() == World.Environment.THE_END
all of our methods ignore that it can be custom world with same environment

yes but also require the name to be fixed or it to be the second world
neither are reliable

hey @wet breach
how do i actually check if event is getting called
in sources
first time looking through sources
isn't it really getting called
even has own handlers
and actually just a base for other events to extend from
drowsy helm
what are you trying to do?
you can just listen to InventoryEvent if that's what you're asking
fluid river
yeah
is it gonna work like combined event of it's subs
listening to everything
related
drowsy helm
yeah
drowsy helm
so any event that extends InventoryEvent will also get called
wet breach
so any event that extends InventoryEvent will also get called
this doesn't hold true for all generic events
drowsy helm
ah doesn't it?
wet breach
no, there is some generic ones that are implemented but not all of them
fluid river
this doesn't hold true for all generic events
still
i was right
you can easily call InventoryEvent
so the guys who suggested it to me were right too
fluid river
mfw "where are noobs" but no knowledge on bt
how is buildtools related to java core
i just ignored it
never used
and never really had to
wet breach
i was right
is it implemented?
fluid river
is it implemented?
yeah
it has handlers and you can listen to it, and it's not abstract of course
wet breach
I never said specifically that you couldn't use it either
wet breach
it has handlers and you can listen to it, and it's not abstract of course
that doesn't mean it is implemented
I can put a handler in any class I want
doesn't mean it is used

let's put this thing here for no reason
generic events are mostly there to extend off of for the API or to make your own custom events
fluid river
i remember i listened to it already in my multipaged gui plugin
wet breach
anyways I never said you couldn't specifically listen to that event
all I said is that generic events generally are not implemented
and really should check to make sure that it is
fluid river
all I said is that generic events generally are not implemented
but not all of them
my point was there are several
wet breach
there isn't several
fluid river
which are both implemented and have subs
fluid river
there isn't several
alright
wet breach
having subs has nothing to do with being implemented
you can have a sub, and the parent not be used
fluid river
isn't it like the same
wet breach
no
fluid river
sorry for my bad eng
it sounds literally the same for me
several like more than one
but not much

I have a bridge that sends commands to be executed to bungeecord and this is the way it sends them:
ByteArrayDataOutput out = ByteStreams.newDataOutput();
out.writeUTF(executor.getExecutable().replace("%player%", player.getName()));
System.out.println(executor.getExecutable().replace("%player%", player.getName()));
player.sendPluginMessage(plugin, "hqueue:inventory", out.toByteArray());```
The commands arrive this way (as attached) in the bungeecord channel and, rightly, are not dispatched
```java
@EventHandler
public void onPluginMessageReceived(PluginMessageEvent event) {
System.out.println("Data received: " + new String(event.getData()) + " --r");
if(!event.getTag().equals("hqueue:inventory")) return;
System.out.println("Data received: " + new String(event.getData()));
ProxyServer.getInstance().getPluginManager().dispatchCommand(ProxyServer.getInstance().getConsole(), new String(event.getData()));

wait, why include 0x80 in the calculations?
in the protocol wiki it says unused
wet breach
in the protocol wiki it says unused
because I copied what you had above
and just didn't really read what you had there
try it again without x80 then? lol
torn oyster
yep
what does >> do
and <<
also still doesn't work
ffs
why are packets so bad
wet breach
is signed right shift << is left shift
smoky oak
and with three its unsigned iirc
wet breach
>>> is the same as << but right shift
wet breach
and with three its unsigned iirc
correct
smoky oak
it moves the bits of a value around, in the direction the arrow's pointing
so for example
0b00001101 is 13 (8 + 4 + 1)
if u do << on that
it turns into 0b00011010, which is 26 (16 + 8 + 2)
torn oyster
what's the difference between signed and unsigned??
wet breach
fun fact, you only notice the difference between >> and >>> when the number is negative
with >> it will shift a 1 into the least significant bit area, where as >>> shifts a 0 there regardless
so >> can literally change a negative to a positive or vice versa because of a 1 being the next digit to shift over regardless if it is suppose to be negative or not
smoky oak
reason for that is that the first bit of a number is usually the sign bit (the marker if its positive or negative), and its a 1 for negative due to math reasons
bitshifting unsigned and signed does not or does account for that one bit
torn oyster
