Lava generation problem in forge #651-652

Posted April 14, 201312 yr

I noticed the lava at the bottom of the world when using forge 651-652 is not generating properly. It creates some of the source blocks for the pools but not all of them (usually only a couple of blocks in the corners). The result is all the lava pools at the bottom of the world generate as a couple of separate lava flows instead of a single lake - which can manifest as small caves at bedrock with lava walls (since they didn't fill in properly).

I disabled all of my mods thinking one of them caused it but the problem persisted. I also noticed that forge 650 generates fine, and I passed a surface lava lake that also appeared fine.

Got a seed and location I can test, I noticed tat the world gen create flowing lava blocks, but thats how vanilla does it.

We did make a small change to this recently, but the logic itself is doing the same thing as before out change:

Note that both the segment we remove and add use Block.lavaMoving

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

It includes a seed and location to test with.

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?
