I spawned the entity within 4 blocks of me (what I set the distance to) and it still crashed.

What kind of problem?

It is telling me that that is what caused the error. I shoul've mentioned this but I have the original code in my onLivingUpdate in my entity's class

Which problem? You have not mentioned any kind of problem except "it crashed".

"Doctor, it hurts." - "Where?" - "DOCTOR, IT HURTS!"

As soon as I spawn the entity in the world it crashes, and if I already have the entity in the world it crashes before I can even see the world.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

DO NOT PM ME WITH PROBLEMS. No help will be given.

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

My f***ing god.
You just assume that
getClosestPlayerToEntity
will always return a player. But what if there is nobody nearby? Then it will return
null
. And you can't access fields or call methods on
null
.
Seriously, if you just completely disregard anything we say, then yes, your problems will not magically disappear in a puff of smoke.

Does that mean it is not possible to do what I want to do?

What happens when the player doesn't hold any item in his selected slot in the hotbar ?

Then
getCurrentItem
will return null (or
ItemStack.EMPTY
in non-outdated Minecraft versions).

(I know, I just want to let him figure it out by himself what are the cases and the results)

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)

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

Bad pathfinding for big mobs (1.21.1)

I've struggled with this for way too long now, so I have decided to ask for some assistance here because there is almost no information about this online.

I made a hostile mob and I built it like this:
public static final Supplier<EntityType<Bunyip>> BUNYIP = ENTITY_TYPES.register("bunyip" , () -> EntityType.Builder. of(Bunyip::new, MobCategory.MONSTER).sized(3f, 2.5f).eyeHeight(1.75f).build("bunyip"));

However, I have discovered that a BoundingBox of 3 is too big for the vanilla pathfinding to work well. In fact, anything bigger than a block will not work well. This is especially noticeable when having it chase a player in a negative X and/or negative Z direction. The mob starts spinning, walking backwards, walking diagonally, etc.

I am using the Goal system:
protected void registerGoals() { super.registerGoals(); this.goalSelector.addGoal(1, new MeleeAttackGoal(this, 1.25, true)); this.targetSelector.addGoal(2, new NearestAttackableTargetGoal<>(this, Player.class, true, true)); }

This does not seem to be a me issue as the ravager, one of the biggest vanilla mobs, also struggles with proper pathfinding. I am a bit familiar with how Minecraft's pathfinding works, but not enough to make a pathfinding system from scratch (or at least not in a reasonable amount of time). Is there any way to fix this with some tweaks or will I have to make a custom pathfinding system?
