[1.16.5] Server crashes on launching because of ArmorItems

Posted July 25, 20214 yr

Hi, so basically I try to launch the server to test my mod on a server, but it crashes on starting because of an "AbstractMethodError : null" on my ArmorItems.

I use a DeferredRegister to register my items, and in these I register some ArmorItems :

public static final RegistryObject<ArmorItem> ARGENTITE_HELMET     = items.register("argentite_helmet", () -> new ArmorItem(ModArmorMaterial.ARGENTITE, EquipmentSlotType.HEAD, new Item.Properties().maxStackSize(1).group(ModItemGroups.ARMORS_TAB)));
	public static final RegistryObject<ArmorItem> ARGENTITE_CHESTPLATE = items.register("argentite_chestplate", () -> new ArmorItem(ModArmorMaterial.ARGENTITE, EquipmentSlotType.CHEST, new Item.Properties().maxStackSize(1).group(ModItemGroups.ARMORS_TAB)));
	public static final RegistryObject<ArmorItem> ARGENTITE_LEGGINGS   = items.register("argentite_leggings", () -> new ArmorItem(ModArmorMaterial.ARGENTITE, EquipmentSlotType.LEGS, new Item.Properties().maxStackSize(1).group(ModItemGroups.ARMORS_TAB)));
	public static final RegistryObject<ArmorItem> ARGENTITE_BOOTS      = items.register("argentite_boots", () -> new ArmorItem(ModArmorMaterial.ARGENTITE, EquipmentSlotType.FEET, new Item.Properties().maxStackSize(1).group(ModItemGroups.ARMORS_TAB)));

What is wrong here ? When I launch it on client I don't have any problems at all

Edit : The error :

[main/ERROR] [ne.mi.fm.ja.FMLModContainer/LOADING]: Caught exception during event RegistryEvent.Register<minecraft:item> dispatch for modid alcamod
java.lang.AbstractMethodError: null

please post the full log
did you register your DeferredRegister in your main mod class?

Do not use @OnlyIn.

Use @Override when overriding methods.

Oh I didn’t see the OnlyIn, such a stupid thing 😅, thanks got it to work

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

You can add mob spawns using Forge's Biome Modifiers feature. I won't go into details on how to use a data generator for them, but here's a simple example:
{ "type": "forge:add_spawns", // Required "biomes": "#namespace:biome_tag", // Accepts a biome id, [list of biome ids], or #namespace:biome_tag "spawners": { "type": "namespace:entity_type", // Type of mob to spawn "weight": 100, // int, spawn weighting "minCount": 1, // int, minimum pack size "maxCount": 4 // int, maximum pack size } }This JSON file would go somewhere like this: data/modid/forge/biome_modifier/your_biome_modifier.json

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?
