Vehicle (Spigot-API 1.18.2-R0.1-SNAPSHOT API)

declaration: package: org.bukkit.entity, interface: Vehicle

#

a vehicle is a vehicle. something that can be ridden

#

upbeat tiger In Java docs it exaplains u like the use of banner in org.bukkit.....

what exactly is your question

upbeat tiger Mar 18, 2022, 5:22 PM

#

I want to code

tender shard Mar 18, 2022, 5:22 PM

#

what are you trying to do

#

exactly

upbeat tiger Mar 18, 2022, 5:22 PM

#

In Java docs

tender shard Mar 18, 2022, 5:23 PM

#

you can't code in java docs, it's not a coding language

upbeat tiger Mar 18, 2022, 5:23 PM

#

It oy exaplains u what things are

#

But

#

In this case

#

I wanna code

#

So

#

From where can I learn the code of Java docs

tender shard Mar 18, 2022, 5:23 PM

#

it basically explains everything

#

upbeat tiger Exactly my point

Oh that is the stash

tender shard Mar 18, 2022, 5:24 PM

#

I doubt he cares about how the javadocs were generated

calm whale Mar 18, 2022, 5:24 PM

#

@tender shard it seems that java biome.getClass().getDeclaredField("k").getClass() has no fields

tender shard Mar 18, 2022, 5:25 PM

#

calm whale <@!632994436401594368> it seems that ```java biome.getClass().getDeclaredField("...

oh I am sorry

#

you of course have to first get the object that's in that "k" field

#

and then get the class of that object

#

so ```java
biome.getClass().getDeclaredField("k").get(biome).getClass()

override the /help command

#

by declaring "/help" to be a command in your plugin.yml

terse ore Mar 18, 2022, 5:26 PM

#

I just make another command named /help?

Is there no collision detection between player and block that I can use (cant find it in javadocs).

terse ore Mar 18, 2022, 5:27 PM

#

commands.yml?

#

plugin.yml you mean

quiet ice Mar 18, 2022, 5:27 PM

#

overriding help will not work as you can still do /minecraft:help

#

No, commands.yml

#

At least I think so

terse ore Mar 18, 2022, 5:27 PM

#

quiet ice overriding help will not work as you can still do `/minecraft:help`

I just want that /help does another thing

upbeat tiger Mar 18, 2022, 5:27 PM

Lemme explain you in a simple way, suppose i wanna code an explosion, javadocs show in which importstatement u should do it on org.bukkit....

idc if /minecraft:help still works

quiet ice Mar 18, 2022, 5:27 PM

Commands.yml is the simplest solution either way

tender shard Mar 18, 2022, 5:27 PM

to also prevent people from doing /minecraft:help, one would have to listen to the PlayerCommandPreProcessEvent or however it's called

terse ore Mar 18, 2022, 5:28 PM

I really do not care

tender shard Mar 18, 2022, 5:28 PM

#

to get your own /help you can just declare your own "help" command

terse ore Mar 18, 2022, 5:28 PM

#

I just want /help for making a menu

upbeat tiger Mar 18, 2022, 5:28 PM

From which website can I do that

tender shard Mar 18, 2022, 5:28 PM

#

yes, as said, declare "help" to be a command in your plugin.yml

quiet ice Mar 18, 2022, 5:28 PM

#

upbeat tiger From which website can I do that

as we said, none

upbeat tiger Mar 18, 2022, 5:28 PM

Then how to learn

quiet ice Mar 18, 2022, 5:28 PM

collisions are basically done client side

tender shard Mar 18, 2022, 5:30 PM

that's why clients can cheat themselves through blocks etc

🤔 What Am I supposed to use to replace 'UNKOWN' ? I need a **BiomeBase.d** type var, so I would need to cast data into **BiomeBase.d** it but it's impossible

If you send me your server .jar, I'll write it up for you

quiet ice Mar 18, 2022, 5:33 PM

#

tender shard Mar 18, 2022, 5:34 PM

#

quiet ice `temperatureModifier.get(data.get(oldBiome))` I'd say

nope

quiet ice Mar 18, 2022, 5:35 PM

#

I. e. you'd have something like

Field dataField = oldBiome.getClass().getDeclaredField("k");
dataField.setAccessible(true);
var dataInstance = dataField.get(oldBiome);
Class<?> dataClass = dataInstance.getClass();

Field temperatureModifier = dataClass.getDeclaredField("d");
temperatureModifier.setAccessible(true);

BiomeBase.TemperatureModifier modifier = (BiomeBase.TemperatureModifier) temperatureModifier.get(dataInstance);

tender shard Mar 18, 2022, 5:35 PM

#

as said, BiomeBase -> get field "k" -> this returns a BiomeBase.d -> from that, call the "d" field on the BiomeBase.d object

calm whale Mar 18, 2022, 5:35 PM

#

tender shard nope

well actually I have no more error with it, I have to test the next step

tender shard Mar 18, 2022, 5:37 PM

#

try this again pls:

#

            BiomeBase biome = null;
            Object biomeBaseD = biome.getClass().getDeclaredField("k").get(biome);
            Class biomeBaseDClazz = biomeBaseD.getClass();
            Field temparetureModifierField = biomeBaseDClazz.getDeclaredField("d");
            BiomeBase.TemperatureModifier modifier = (BiomeBase.TemperatureModifier) temparetureModifierField.get(biomeBaseD);

#

this should put the TemperatureModifier of "biome" into the "modifier" variable

#

I am 99% sure that it works. if it doesn't, please show the exact error message you get while using exactly this code ^

#

(obviously you still have to make the fields accessible)

#

so again, here's the full code:

#

BiomeBase biome = null;
            biome.getClass().getDeclaredField("k").setAccessible(true);
            Object biomeBaseD = biome.getClass().getDeclaredField("k").get(biome);
            Class biomeBaseDClazz = biomeBaseD.getClass();
            Field temparetureModifierField = biomeBaseDClazz.getDeclaredField("d");
            temparetureModifierField.setAccessible(true);
            BiomeBase.TemperatureModifier modifier = (BiomeBase.TemperatureModifier) temparetureModifierField.get(biomeBaseD);

#

this also makes the fields accesible

quiet ice Mar 18, 2022, 5:40 PM

#

probably about the same thing I proposed

tender shard Mar 18, 2022, 5:40 PM

#

might be true, haven't checked

#

I used names similar to the classes so I can keep track of what classes I am actually having

#

reflection can be very nasty

calm whale Mar 18, 2022, 5:41 PM

Protocollib is not meant to replace nms packet usage. Its so you can handle packets and still support a ton of versions without having to
rewrite everything new for every version.

You are shading ProtocolLib in most likely. Make sure you use the provided scope for the maven dependency.

tender shard Mar 18, 2022, 6:34 PM

#

oh yeah that might also be the problem

#

either you're shading it (bad, no, no, don't do that) or you're not properly depending on it

the only valid reason I see for using protocollib is to listen to incoming packets

lost matrix Mar 18, 2022, 6:35 PM

There are wrapper classes for packets

tender shard Mar 18, 2022, 6:35 PM

#

not in protocollib itself. they were included like 8 years ago IIRC

lost matrix Mar 18, 2022, 6:35 PM

And writing one takes like 10 mins. You just look at the protocol specification and wrap all the struct calls.

tender shard Mar 18, 2022, 6:36 PM

I can easily wrap a packet without protocollib though

#

I'd rather do new WhatEverPacket() then new Packet(SomeWeirdNameThatDoesntMatchTheMojangName) and then have to do setInt 7 times

Java 17 is the best

using 1.8 wont work for a 1.17 plugin?

tender shard Mar 18, 2022, 7:28 PM

#

1.8 works for 1.17 plugins

wet breach Mar 18, 2022, 7:28 PM

#

no because they are compiled with two different versions that are not compatible

tender shard Mar 18, 2022, 7:28 PM

#

TL;DR: 1.8 works for all plugins

#

16 only works on 1.17+

fluid cypress Mar 18, 2022, 7:28 PM

i compiled a 1.17 plugin with java 1.8, i think, some days ago

if you only need to support MC 1.18+, then yes, go for java 17

fluid cypress i compiled a 1.17 plugin with java 1.8, i think, some days ago

the way it works, is you can't run plugins that were compiled with a higher version of java then the current java version you are using to run the server

tender shard Mar 18, 2022, 7:30 PM

#

fluid cypress but then why i cant compile a 1.18 plugin with java 1.8?

because the MC 1.18 code is written in java 17 and java 8 cannot read java 17 files

wet breach Mar 18, 2022, 7:30 PM

#

because it is quite possible that the methods in that plugin are specific to java 17

viral crag Mar 18, 2022, 7:30 PM

#

too much broken java

wet breach Mar 18, 2022, 7:30 PM

which don't exist in java 8

or specific to spigot/mc version as well

fluid cypress but then why i cant compile a 1.18 plugin with java 1.8?

For what it's worth... you can.

#

Bukkit is still compiled against 8

wet breach Mar 18, 2022, 7:31 PM

#

there are methods in java 17 that do exist in older versions, however java 17 introduces new methods not present in older ones

worldly ingot Mar 18, 2022, 7:31 PM

#

If you are depending on CraftBukkit or NMS, however, you will need to compile with 17

#

Both of which are compiled against 17

tender shard Mar 18, 2022, 7:31 PM

#

as almost always, choco is right

fluid cypress Mar 18, 2022, 7:32 PM

#

ok, doesnt matter, ill compile for mc 1.18

#

i think thats all about maven

worldly ingot Mar 18, 2022, 7:32 PM

#

At which point you can compile with Java 8 if you want but because Minecraft itself requires 17, your plugin might as well do the same unless you intend on supporting anything below 1.18

fluid cypress Mar 18, 2022, 7:32 PM

#

what about gradlew? is it too different? is it commonly used with spigot/minecraft?

worldly ingot Mar 18, 2022, 7:32 PM

#

Probably less than Maven but still viable, yes

tender shard Mar 18, 2022, 7:33 PM

#

again, cheat sheet:

Want to support SPigot 1.16 and lower, AND higher`
Use java 8

Want to support ONLY Spigot 1.17+
Use java 16

Want to support ONLY Spigot 1.18+
Use java 17

midnight shore What is the difference from Bukkit.getScheduler().scheduleSyncDelayedTask() and ...

The one has a delay the other is executed as soon as possible

#

Wait.

#

No its the arguments that are different. scheduleSyncDelayedTask() takes a runnable that is wrapped by a BukkitRunnable

#

runTaskLater consumes a BukkitTask

Creating Random Numbers is hard. Especially if all you have available to do it, is digital hardware and deterministic software. Where is the randomness in that?

grim ice ThreadLocalRandom, on windows

idk how windows does it but ti's probably similar

#

let me explain

#

almost every OS has some kind of entropy pool

#

that gets filled with "somehow random" information

#

like

#

how does the user move the mouse

#

how was the last ping received from the last internet thingy

#

how large was the last accessed file

#

stuff that could IN THEORY be predicted

#

but in reality, noone can predict this

#

and based of that numbers, it fills the pool of entropy

#

and that's the seeds used to generate random numbers

#

you can easily see that on linux by doing tail -f /dev/random

#

it'll stop after some time

#

now move your mouse in random directions

#

somehow now it prints out new numbers again

grim ice Mar 18, 2022, 9:25 PM

#

i

tender shard Mar 18, 2022, 9:25 PM

because it generates new random numbers based off your mouse movement

#

but, that's not the only source

#

if you have a microhpone

it also uses the input of your mic to create new entropy

etc etc
