First-person controller y-pos logic in Ursina

How to configure slf4j (for JDA) to work with log4j (for Minecraft Paper)?
Asked 2022-Mar-11 at 16:05I'm making plugin for Minecraft - 'Paper' exactly. And it uses JDA for Discord bot function.
The problem is, Minecraft(Paper) uses log4j as its logging library. JDA uses slf4j as its logging library. I want JDA to use log4j so that error message of JDA would be shown in console as plugin's error message. (See EDIT2 for actual logs)
No System.out.println() because Minecraft(Paper) will complain about using it.
No Logback because I think it is another logging library, thus it cannot work well with Minecraft(Paper)'s logging system (no JDA logs in Minecraft log etc.). I don't want to implement another logging library when there is already logging system provided by Minecraft, which is log4j.
JDA wiki only describes about Logback so I have to find my own way for making JDA with Minecraft's logging system, but it was no success.
For example:
1// Something went wrong in JDA and shows stacktrace
2[05:20:26] [Server thread/ERROR]: [MyPlugin] [JDA] 'JDA Error Message'
3(prints stacktrace of the error)
4
5// Show debug message of WebSocketClient (Since it is debug message, this can be turned off)
6[05:20:26] [Server thread/DEBUG]: [MyPlugin] [JDA] WebSocketClient - Connected to WebSocket
7
8// Show JDA message when JDA bot is loaded
9[05:20:26] [Server thread/DEBUG]: [MyPlugin] [JDA] JDA - Finished Loading!
10These all messages should be part of the Minecraft(Paper)'s logging system, not mimicing it. This means, it should use JavaPlugin#getLogger().info() or something like this in somewhere of the code.
How to make JDA to be like this?
Just implementing log4j-slf4j18-impl doesn't work. I think I should do something about JDA's logging stuff.
EDIT: Here is current build.gradle file content. LINK
Currently, my plugin implements log4j-slf4j-impl for JDA.
ANSWER
Answered 2022-Feb-27 at 07:57Log4j 2 SLF4J Binding exists for that purpose.
It is an SLF4J logger implementation (like slf4j-simple) that logs everything to log4j. In other words, everything logged with SLF4J will be forwarded to log4j.
In order to use it, just add the following to your pom.xml (see this):
1// Something went wrong in JDA and shows stacktrace
2[05:20:26] [Server thread/ERROR]: [MyPlugin] [JDA] 'JDA Error Message'
3(prints stacktrace of the error)
4
5// Show debug message of WebSocketClient (Since it is debug message, this can be turned off)
6[05:20:26] [Server thread/DEBUG]: [MyPlugin] [JDA] WebSocketClient - Connected to WebSocket

12 <artifactId>log4j-slf4j18-impl</artifactId>

15If you use Gradle, it would look like this:
1// Something went wrong in JDA and shows stacktrace
2[05:20:26] [Server thread/ERROR]: [MyPlugin] [JDA] 'JDA Error Message'

QUESTION
Log4j vulnerability - Is Log4j 1.2.17 vulnerable (was unable to find any JNDI code in source)?
Asked 2022-Feb-01 at 15:47With regard to the Log4j JNDI remote code execution vulnerability that has been identified CVE-2021-44228 - (also see references) - I wondered if Log4j-v1.2 is also impacted, but the closest I got from source code review is the JMS-Appender.
The question is, while the posts on the Internet indicate that Log4j 1.2 is also vulnerable, I am not able to find the relevant source code for it.
Am I missing something that others have identified?
Log4j 1.2 appears to have a vulnerability in the socket-server class, but my understanding is that it needs to be enabled in the first place for it to be applicable and hence is not a passive threat unlike the JNDI-lookup vulnerability which the one identified appears to be.
Is my understanding - that Log4j v1.2 - is not vulnerable to the jndi-remote-code execution bug correct?
ReferencesThis blog post from Cloudflare also indicates the same point as from AKX....that it was introduced from Log4j 2!
Update #1 - A fork of the (now-retired) apache-log4j-1.2.x with patch fixes for few vulnerabilities identified in the older library is now available (from the original log4j author). The site is https://reload4j.qos.ch/. As of 21-Jan-2022 version 1.2.18.2 has been released. Vulnerabilities addressed to date include those pertaining to JMSAppender, SocketServer and Chainsaw vulnerabilities. Note that I am simply relaying this information. Have not verified the fixes from my end. Please refer the link for additional details.
ANSWER
Answered 2022-Jan-01 at 18:43The JNDI feature was added into Log4j 2.0-beta9.
Log4j 1.x thus does not have the vulnerable code.
QUESTION
Minecraft Plugin ClassNotFound Error from External JAR
Asked 2021-Dec-31 at 16:46I am trying to build a plugin for a Minecraft Spigot server that ultimately I would like to be able to communicate over serial with things connected to my PC (server is running locally on the PC as well).
I have been able to build and run the plugin and manipulate player/blocks in the game so I know the build process for my base plugin is working. My trouble started when I began trying to include an extra dependency: jSerialComm
I added the dependency entry in my pom.xml file:
1<dependency>
2 <groupId>com.fazecast</groupId>
3 <artifactId>jSerialComm</artifactId>
4 <version>[2.0.0,3.0.0)</version>
5 <scope>provided</scope>
6</dependency>
7I added some basic code to import classes from jSerialComm and do something basic with them inside of a command in my plugin:
1<dependency>
2 <groupId>com.fazecast</groupId>
3 <artifactId>jSerialComm</artifactId>
4 <version>[2.0.0,3.0.0)</version>
5 <scope>provided</scope>
6</dependency>
7import com.fazecast.jSerialComm.SerialPort;
8
9public class CommandCheck implements CommandExecutor {
10
11 @Override
12 public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
13 if (sender instanceof Player){
14 System.out.println(SerialPort.getCommPorts());
15 }
16 return false;
17 }
18}
19This builds fine, I'm using InteliJ and it does recognize the SerialPort class (no red underlines).
But when this command runs in the game I get a Class Not Found error:
1<dependency>
2 <groupId>com.fazecast</groupId>
3 <artifactId>jSerialComm</artifactId>
4 <version>[2.0.0,3.0.0)</version>

53I have unzipped and looked inside of the built jar file and the jSerialComm jar file is successfully being included within my plugin jar:
What do I need to do in order to successfully use an external JAR file (jSerialComm specifically) from inside of a Minecraft plugin? Or alternatively, is there some built-in way that I can connect and communicate over serial ports without needing an external JAR and therefore not needing anything "special" in order to work?
ANSWER
Answered 2021-Dec-31 at 16:46Even if the JAR is present in your plugin, the classes of the JAR are not loaded in the classpath and Spigot cannot access the classes.
You can use a plugin, such as the maven-shade-plugin, which copies all classes from your API-JAR to your Plugin-JAR.
First, set the scope from provided to compile.

94QUESTION
Infer dependencies in Gradle subproject from its parent project
Asked 2021-Dec-15 at 04:07I currently have 3 subprojects in my Gradle project, structured like so:
1Main Project
2|
3-- Project A
4-- Project B
5-- Common Src
6Project A has dependency on Lib A and Common Src, and Project B has dependency on Lib B and Common Src. Lib A and Lib B contain different implementations of the same classes.
My plan for Common Src project was to house all of the utility classes, necessarily depending on both Lib A and Lib B.
Is there a way to set this up, and how should my gradle project look like?
Things that I've tried:- I've tried to remove Common Src as a subproject and just include it in the sourceSets of Project A and Project B. However, IntelliJ seems to mark Common Src as sources root of Project A, and even though build-through-gradle works, I cannot get IntelliJ to recognize that Project B also has sources root in Common Src.
- Add both Lib A and Lib B to dependency of Common Src, but obviously that doesn't work.
I've created a Minecraft mod compatible with both Forge (Project A) and Fabric (Project B) modloaders. I have utility classes in both projects that have the same source code but need to be compiled twice, each time with a different dependency. I don't want to have to write the code twice each time I want to change something in the Utility classes.
ANSWER
Answered 2021-Dec-15 at 04:07EDIT: I've found a workaround:
- In both
Project AandProject B, add a task in each of theirbuild.gradleto copy the source files fromCommon Srcto the build directory of each project. - Configure
sourceSetsof bothProject AandProject Bto include source files from the build folder we just copied into - Configure
Common Srcto be a gradle subproject, and addLib A(orLib B) to the dependencies ofCommon Src(just to get IntelliJ some context)
QUESTION
Minecraft Forge 1.7.10 Custom Entity Not Spawning On The Client?
Asked 2021-Dec-02 at 22:58In my Minecraft Forge mod for 1.7.10. I am aware that this version is arguably old news, but it is my favorite version and all of my modding experience is with this version.
I am creating a custom TNT block. The issue is the primed version is not rendering. When ignited, the TNT disappears, and then shortly later there is an explosion. If the TNT was placed in the air, the explosion is below like it should be due to the primed TNT falling. The issue is that it is not rendering. When I use fn+f3+b to show hitboxes, no hitbox is shown.
The issue is the entity being spawned on the server does not replicate to the client. I know this because:
Switching out the entity renderer with the default
RenderTNTPrimedstill fails to render at all instead of rendering the default TNT hence my custom renderer class cannot be the issue.Switching out my custom entity class with the copy paste vanilla
EntityTNTPrimedcode also does not solve the problem. If the problem was with my custom entity class then using bona fide vanilla code would fix the problem but it doesnt.The entity and its renderer are being registered using
RenderingRegistry.registerEntityRenderingHandler()from the client proxy andEntityRegistry.registerGlobalEntityID()thenEntityRegistry.registerModEntity()ininit()(I had tested the client proxy withSystem.out.println()and the client proxy works).Though the largest evidence of the problem being the TNT spawing on the server but not the client is the fact that removing
if(world.isRemote) return;from the handlers in myBlockTNTclass causes the TNT to render. However I am not supposed to handle igniting the TNT on the client so I am not supposed to have to removeif(world.isRemote) return;. Besides doing this is a pseudo fix, because the entity is still invisible when/summoned.The constructor for
TNTPrimedChargedis only being called from the server, andonUpdate()forTNTPrimedand thusTNTPrimedChargedis also only being called by the server, as demostrated by adding print statements and the logs only show them printed from the SERVER thread.
The BlockTNT class (much of this is derived from vanilla code, but has been designed to take the corresponding custom primed TNT entity class while instantiating, the problem is not here because instantiating a default EntityTNTPrimed instead of the provided primed class does render correctly, but I have included this because this code helped demonstrate the origin of the problem):
1class BlockTNT extends net.minecraft.block.BlockTNT {
2 private final Class primed;
3 public BlockTNT(final Class primed) {
4 this.primed = primed;
5 stepSound = net.minecraft.block.Block.soundTypeGrass;
6 }
7 protected EntityTNTPrimed getPrimed(final World world, final int x, final int y, final int z, final EntityLivingBase igniter) {
8 try {
9 return (EntityTNTPrimed)primed.getDeclaredConstructor(World.class, double.class, double.class, double.class, EntityLivingBase.class).newInstance(world, (double)((float)x+0.5F), (double)((float)y+0.5F), (double)((float)z+0.5F), igniter);
10 } catch (Exception exception) {
11 return null;
12 }
13 }
14 @Override public void onBlockDestroyedByExplosion(final World world, final int x, final int y, final int z, final Explosion explosion) {
15 if(world.isRemote)
16 return;
17 final EntityTNTPrimed tnt = getPrimed(world, x, y, z, explosion.getExplosivePlacedBy());
18 tnt.fuse = world.rand.nextInt(tnt.fuse>>2)+(tnt.fuse>>3);
19 world.spawnEntityInWorld(tnt);
20 }
21 @Override public void func_150114_a(final World world, final int x, final int y, final int z, final int meta, final EntityLivingBase igniter) {
22 if(world.isRemote || (meta&1) == 0)
23 return;
24 final EntityTNTPrimed tnt = getPrimed(world, x, y, z, igniter);
25 world.spawnEntityInWorld(tnt);
26 world.playSoundAtEntity(tnt, "game.tnt.primed", 1.0F, 1.0F);
27 }
28}
29Inside the main mod class I register the entities:
1class BlockTNT extends net.minecraft.block.BlockTNT {
2 private final Class primed;
3 public BlockTNT(final Class primed) {
4 this.primed = primed;
5 stepSound = net.minecraft.block.Block.soundTypeGrass;
6 }
7 protected EntityTNTPrimed getPrimed(final World world, final int x, final int y, final int z, final EntityLivingBase igniter) {
8 try {
9 return (EntityTNTPrimed)primed.getDeclaredConstructor(World.class, double.class, double.class, double.class, EntityLivingBase.class).newInstance(world, (double)((float)x+0.5F), (double)((float)y+0.5F), (double)((float)z+0.5F), igniter);
10 } catch (Exception exception) {
11 return null;
12 }
13 }
14 @Override public void onBlockDestroyedByExplosion(final World world, final int x, final int y, final int z, final Explosion explosion) {
15 if(world.isRemote)
16 return;
17 final EntityTNTPrimed tnt = getPrimed(world, x, y, z, explosion.getExplosivePlacedBy());
18 tnt.fuse = world.rand.nextInt(tnt.fuse>>2)+(tnt.fuse>>3);
19 world.spawnEntityInWorld(tnt);
20 }
21 @Override public void func_150114_a(final World world, final int x, final int y, final int z, final int meta, final EntityLivingBase igniter) {
22 if(world.isRemote || (meta&1) == 0)
23 return;
24 final EntityTNTPrimed tnt = getPrimed(world, x, y, z, igniter);
25 world.spawnEntityInWorld(tnt);
26 world.playSoundAtEntity(tnt, "game.tnt.primed", 1.0F, 1.0F);
27 }
28}

36@EventHandler public void init(FMLInitializationEvent event) {
37 registerTnt(com.examplemod.TNTPrimedCharged.class, "Charged", 0);

40And we register the renderer in the client proxy (again tested and works):

4 this.primed = primed;

115So when the server calls world.spawnEntityInWorld() on my custom entity why does it fail to spawn it on the client as well? How can I fix this because the TNT just disappearing when being ignited is undesirable and I have no idea what else to try. How can I make the custom primed TNT show up on the client?
Upon reverse engineering other similar mods (specifically the Too Much TNT mod), their TNT primed entities successfully render when /summon is used, and they do check for clientside in their TNT block classes. After investigation, I cannot tell what they are doing differently that would cause their entities to render but not mine.
I have spent several unfruitful hours researching this problem, and given that as of this edit this question is second hit for Googling basic search terms like 'Minecraft Forge 1.7.10 Entity Not Rendering' and third for 'Minecraft Forge 1.7.10 Entity Invisible,' it is very likely that further research will be in vain.
The problem is simply that when my mod added entity is spawned on the server thread, it is not also spawned on the client thread, even though it should be. How do I fix this? I tried everything.
ANSWER
Answered 2021-Dec-02 at 22:58It turns out the problem was actually not the entity not spawning on the client. The issue was that the fuse property was being set to 0 on the client even though it is set to 80 on the server. And thus the client side TNT is instantly setDead()ing itself. Implementing cpw.mods.fml.common.registry.IEntityAdditionalSpawnData and then setting the fuse property to the correct value in readSpawnData seems to have solved the problem.
QUESTION
Generate custom ores in custom dimension
Asked 2021-Nov-25 at 16:54I have recently created a custom dimension using data packs in Minecraft 1.16.5. This dimension is a part of a mod that I am writing and I am currently trying to generate custom ores in that dimension; However, I was not able to generate ores in a custom dimension the same way that I generate ores in the Overworld or Nether. As I mentioned the dimension is handled via data packs (.json files) but the biomes are handled in game code (.java). I am very new to Java & modding, any suggestions would be appreciated. Thanks in advance.

117ANSWER
Answered 2021-Nov-25 at 16:54Answering my own question.
Instead of using event.getCategory().equals(SomeBiomeCategory) in the if statement in the OreGen class you should use event.getName().equals(YourModBiomeInit.BiomeName.getId(). Because event.getCategory().equals(SomeBiomeCategory) gets the category of the biome currently generating whilst event.getName().equals(YourModBiomeInit.BiomeName.getId() gets the registered name (or id).
So the if statement would look something like this :
1public class OreGeneration
2{
3 public static void generateOres(final BiomeLoadingEvent event)
4 {
5 // Gigalium :
6 if(!(event.getCategory().equals(Biome.Category.THEEND)))

Special condition - remove all the version numbers from the mods to search for the new version
Asked 2021-Oct-29 at 17:19Trying to create an update script for Minecraft mods and need to be able to remove all the version numbers from the mods to search for the new version.
I have gotten it working to a point but am stuck on one last part. I cannot get it to leave out the 25 from pre25 from that line I need cfm pre (the 25 is the build number which I do not want)
1[A-Za-z].*?(?=-[0-9])|(?<= ).*(?= )|([s].*?[k])|([f].*?[e])

14ANSWER
Answered 2021-Oct-29 at 13:46This part in your pattern is matching too much, as this part .*?(?=-[0-9]) is matching as least as possible chars until it can assert -[0-9] to the right which will match pre25 in pre25-1
You could update the pattern to match an optional part matching digits separated by dots, and in the positive lookahead add asserting optional digits at the beginning [A-Za-z_]+(?:\d+(?:\.\d+)+)?(?=[0-9]*-[0-9]) to reach the hyphen followed by a digit.
You could make the .*? non greedy matching all between spaces as .* can over match in case of more spaces.
The updated pattern (without the capture groups if you want a match only) could look like
1[A-Za-z].*?(?=-[0-9])|(?<= ).*(?= )|([s].*?[k])|([f].*?[e])

How to filter an array on click in react?
Asked 2021-Oct-05 at 23:48So, basically, I'm making a website where you can search for Minecraft hacked clients. There is a search bar on the website, but you have to search in exact terms (different topic lol). Basically on the click of a button (search button) I then want to filter using the search term, (not automatically as I have it now) I've been searching but cant find a way to do it.
Code ->
1import CountUp from 'react-countup';
2import { Link } from 'react-router-dom';
3import '../App.css';
4
5/*Components ->*/
6import Client from '../components/client.js'

8function App() {
9
10 const [search, setSearch] = React.useState({
11 searchname: ''
12 });
13
14 **Array containing client data ->** const [client, setClient] = React.useState([
15 { safestatus: 'safe-status-green', safe: 'Safe (Verified)', name: 'Impact', price: 'Free', mcversion: '1.11.2 - 1.16.5', type: 'Injected', compat: 'None (Stand alone client)', desc: 'The Impact client is an advanced utility mod for Minecraft, it is packaged with Baritone and includes a large number of useful mods.', screen: 'https://impactclient.net/', download: 'https://impactclient.net/'},
16 { safestatus: 'safe-status-green', safe: 'Safe (Verified)', name: 'Future', price: '15€', mcversion: '1.8.9 - 1.14.4', type: 'Injected', compat: 'None (Stand alone client)', desc: 'Vanilla, OptiFine, Forge and Liteloader support, Easy to use account manager, Auto-reconnect mod.', screen: 'https://www.futureclient.net/', download: 'https://www.futureclient.net/'}

ANSWER
Answered 2021-Oct-05 at 23:48Use two pieces of state; one to track the value in your text field and the other to store the search term for filtering. Only set the latter when you click your button
