(1.19.1) Internal Exception: io.netty.handler.codec.DecoderException: java.lang.IndexOutOfBoundsException: readerIndex(27) + len

Posted August 10, 20223 yr

I'm trying to connect to one of my friends modded server (1.19.1) but everytime I click connect this error comes up [ Internal Exception: io.netty.handler.codec.DecoderException: java.lang.IndexOutOfBoundsException: readerIndex(27) + length(1) exceeds writerIndex(27): PooledUnsafeDirectByteBuf(ridx: 27, widx: 27, cap: 27)].

The weird thing is before swapping to my current PC I was able to play just fine on a different computer but after swapping I can't seem to join at all while my other friends are able to join just fine. Here's my debug.log (https://pastebin.com/6jV4VLtp).

Any help would be nice, if I need to give more files lmk

Please add -Dforge.logging.mojang.level=debug to the JVM arguments of your Launcher.
Launch the game and produce the error, then post debug.log from the logs folder in your own thread (create your own thread).

@AthensguyПожалуйста, добавьте -Dforge.logging.mojang.level=debug к аргументам вашего JVM Launcher.
Запустите игру и выдайте ошибку, затем опубликуйте обновленный файл debug.log.

good afternoon, can you please clarify what needs to be done. I added an argument to my minecraft but nothing changed

The output of the logs will change. Please post the new logs.

Boilerplate:

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com You should also read the support forum sticky post.

Launcher -> Installations -> edit the Forge Profile -> More Options -> Add the Argument to the JVM Arguments

How to change player renderer and transform model parts?

I have been trying for a while now to make a custom player renderer, and replace the vanilla player renderer with it. So far I've come up with a custom player renderer class that extends vanilla PlayerRenderer:
package com.FireDude123.BOTW.entity.renderer; import com.mojang.blaze3d.vertex.PoseStack; import net.minecraft.client.player.AbstractClientPlayer; import net.minecraft.client.renderer.MultiBufferSource; import net.minecraft.client.renderer.entity.player.PlayerRenderer; import net.minecraft.client.renderer.entity.EntityRendererProvider; import net.minecraftforge.client.event.RenderPlayerEvent; import net.minecraftforge.common.MinecraftForge; public class PoseablePlayerRenderer extends PlayerRenderer { public PoseablePlayerRenderer(EntityRendererProvider.Context ctx, boolean slim) { super(ctx, slim); System.out.println("here too"); } @Override public void render(AbstractClientPlayer p_117788_, float p_117789_, float p_117790_, PoseStack poseStack, MultiBufferSource p_117792_, int p_117793_) { System.out.println("didnt get here lol"); model.leftArm.xRot=(float)Math.toRadians(160); super.render(p_117788_, p_117789_, p_117790_, poseStack, p_117792_, p_117793_); } } As you can see, the intended purpose of this is to raise the player's left arm by 160 degrees. However, combined with this logic in ClientModEvents:
@Mod.EventBusSubscriber(modid = MODID, bus = Mod.EventBusSubscriber.Bus.MOD, value = Dist.CLIENT) public static class ClientModEvents { @SubscribeEvent public static void onClientSetup(FMLClientSetupEvent event) { EntityRenderers.register((EntityType<? extends AbstractClientPlayer>)(EntityType<?)EntityType.PLAYER, ctx -> new PoseablePlayerRenderer(ctx, true)); EntityRenderers.register(Entities.MAGNESIS_BLOCK.get(), com.FireDude123.BOTW.entity.renderer.BlockDisplayRenderer::new); EntityRenderers.register(Entities.REMOTE_BOMB.get(), ThrownItemRenderer::new); EntityRenderers.register(Entities.CRYONIS_ICE.get(), com.FireDude123.BOTW.entity.renderer.BlockDisplayRenderer::new); EntityRenderers.register(Entities.STASIS_BLOCK.get(), FallingBlockRenderer::new); } @SubscribeEvent public static void registerLayerDefinitions(EntityRenderersEvent.RegisterLayerDefinitions event) { event.registerLayerDefinition(new ModelLayerLocation(new ResourceLocation(BOTW.MODID, "paraglider"), "main"), ParagliderLayer::createBodyLayer); } }(I also have a paraglider layer here for something else, it's working perfectly fine, also I used the slim setting because the player is slim in 1.20.1 forge)
This logic isn't replacing the renderer, as far as I can tell. Can someone please advise as to why, and how to fix it?

How to add my mob to another mod's biome in 1.20.1.

I'm on 1.20.1 and was wondering if there was a way to add a mob I am going to make to a other mod's biome (Regions Unexplored in this case). I am trying to figure this out before I start coding the mod. Could someone point me to a good guide on this? I saw some things about biome modifier's but all the resources are either to short, unhelpful or for a different version. Thanks in advance. (i am a beginner but i have java and modding knowledge so this isn't like a "i am new and don't know anything about coding" problem btw)

Dealing with modded server issues can be a real headache been there! At least you can keep your look stress-free with a fresh low taper fade.

Help with file conversion

Many Forge users seek help with file conversions. Similarly, managing your health can benefit from structured tools like the https://wellness-app.com/calculator/fasting-calculator/ and a free intermittent fasting calculator. These tools help you plan and personalize your fasting and eating windows based on your lifestyle and goals. By entering your preferred fasting duration and meal times, you receive a tailored schedule that makes intermittent fasting easier to follow. Just as mastering file conversions improves modding success, using a fasting calculator brings clarity and structure to your health routine, supporting better results over time.

Cobblemon invalid player data

Hi everyone, I keep getting "invalid player data" when trying to log onto my friend's server. Log analysis says to remove Night Lights and ImmediatelyFast, but that doesn't work. Any insight is appreciated
