hi,

I started to update one of my mods to 1.8 this weekend and I'm stuck on the bow textures.

By doing research on how the minecraft bow work, I found this in net.minecraft.client.renderer.entity.RenderItem :

    public void renderItemModelForEntity(ItemStack stack, EntityLivingBase entityToRenderFor, ItemCameraTransforms.TransformType cameraTransformType)
    {
        IBakedModel ibakedmodel = this.itemModelMesher.getItemModel(stack);

        if (entityToRenderFor instanceof EntityPlayer)
        {
            EntityPlayer entityplayer = (EntityPlayer)entityToRenderFor;
            Item item = stack.getItem();
            ModelResourceLocation modelresourcelocation = null;

            if (item == Items.fishing_rod && entityplayer.fishEntity != null)
            {
                modelresourcelocation = new ModelResourceLocation("fishing_rod_cast", "inventory");
            }
            else if (item == Items.bow && entityplayer.getItemInUse() != null)
            {
                int i = stack.getMaxItemUseDuration() - entityplayer.getItemInUseCount();

                if (i >= 18)
                {
                    modelresourcelocation = new ModelResourceLocation("bow_pulling_2", "inventory");
                }
                else if (i > 13)
                {
                    modelresourcelocation = new ModelResourceLocation("bow_pulling_1", "inventory");
                }
                else if (i > 0)
                {
                    modelresourcelocation = new ModelResourceLocation("bow_pulling_0", "inventory");
                }
            }
            else
            {
                modelresourcelocation = item.getModel(stack, entityplayer, stack.getMaxItemUseDuration() - entityplayer.getItemInUseCount());
            }

            if (modelresourcelocation != null)
            {
                ibakedmodel = this.itemModelMesher.getModelManager().getModel(modelresourcelocation);
            }
        }

        this.renderItemModelTransform(stack, ibakedmodel, cameraTransformType);
    }

but apparently forge did not have hook or event to allow modder to use it.

Is there any other way to do a custom bow or it would add an event or hook to forge ?

                modelresourcelocation = item.getModel(stack, entityplayer, stack.getMaxItemUseDuration() - entityplayer.getItemInUseCount());

Indeed, it was just under my eyes and I didn't even see it x)

thank you !

 

EDIT :

It's working, if someone else has the same problem, here's how:

package your.package;

import net.minecraft.client.resources.model.ModelResourceLocation;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.ItemBow;
import net.minecraft.item.ItemStack;

public class ItemCustomBow extends ItemBow
{
    @Override
    public ModelResourceLocation getModel(ItemStack stack, EntityPlayer player, int useRemaining)
    {
        ModelResourceLocation modelresourcelocation = new ModelResourceLocation(TestMod.MODID + ":custom_bow", "inventory");

        if(stack.getItem() == this && player.getItemInUse() != null)
        {
            if(useRemaining >= 18)
            {
                modelresourcelocation = new ModelResourceLocation(TestMod.MODID + ":custom_bow_pull2", "inventory");
            }
            else if(useRemaining > 13)
            {
                modelresourcelocation = new ModelResourceLocation(TestMod.MODID + ":custom_bow_pull1", "inventory");
            }
            else if(useRemaining > 0)
            {
                modelresourcelocation = new ModelResourceLocation(TestMod.MODID + ":custom_bow_pull0", "inventory");
            }
        }
        return modelresourcelocation;
    }
}

and the main class :

package your.package;

import net.minecraft.client.Minecraft;
import net.minecraft.client.renderer.ItemModelMesher;
import net.minecraft.client.resources.model.ModelBakery;
import net.minecraft.client.resources.model.ModelResourceLocation;
import net.minecraft.item.Item;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.common.Mod.EventHandler;
import net.minecraftforge.fml.common.event.FMLInitializationEvent;
import net.minecraftforge.fml.common.event.FMLPreInitializationEvent;
import net.minecraftforge.fml.common.registry.GameRegistry;
import net.minecraftforge.fml.relauncher.Side;
import net.minecraftforge.fml.relauncher.SideOnly;

@Mod(modid = TestMod.MODID, name = "Test Mod", version = "1.0.0", acceptedMinecraftVersions = "[1.8.0,)")
public class TestMod
{
    public static final String MODID = "testmod";
    public static Item customBow;
    
    @EventHandler
    public void preLoad(FMLPreInitializationEvent event)
    {
        customBow = new ItemCustomBow().setUnlocalizedName("customBow");
        GameRegistry.registerItem(customBow, "custom_bow");
    }
    
    @EventHandler
    public void load(FMLInitializationEvent event)
    {
        if(event.getSide().isClient())
        {
            ModelBakery.addVariantName(customBow, new String[] {MODID + ":custom_bow", MODID + ":custom_bow_pull0", MODID + ":custom_bow_pull1", MODID + ":custom_bow_pull2"});

            registerItem(customBow, 0, MODID + ":custom_bow");
            registerItem(customBow, 1, MODID + ":custom_bow_pull0");
            registerItem(customBow, 2, MODID + ":custom_bow_pull1");
            registerItem(customBow, 3, MODID + ":custom_bow_pull2");
        }
    }
    
    @SideOnly(Side.CLIENT)
    public static void registerItem(Item item, int metadata, String itemName)
    {
        ItemModelMesher mesher = Minecraft.getMinecraft().getRenderItem().getItemModelMesher();
        mesher.register(item, metadata, new ModelResourceLocation(itemName, "inventory"));
    }
}

    • does anyone know how to incorporate custom noise settings into a custom dimension through the use of datagen, I have created a custon json file for the noise settings that I want but I just don't know how to get it to register with the generated json file of the custom dimension.   here is the code for the dimension class package net.hurst.lustria.worldgen.dimension; import com.mojang.datafixers.util.Pair; import net.hurst.lustria.Lustria; import net.hurst.lustria.worldgen.biome.ModBiomes; import net.hurst.lustria.worldgen.registries.LustriaNoiseSettings; import net.minecraft.core.HolderGetter; import net.minecraft.core.registries.Registries; import net.minecraft.data.worldgen.BootstapContext; import net.minecraft.resources.ResourceKey; import net.minecraft.resources.ResourceLocation; import net.minecraft.tags.BlockTags; import net.minecraft.util.valueproviders.ConstantInt; import net.minecraft.world.level.Level; import net.minecraft.world.level.biome.*; import net.minecraft.world.level.dimension.BuiltinDimensionTypes; import net.minecraft.world.level.dimension.DimensionType; import net.minecraft.world.level.dimension.LevelStem; import net.minecraft.world.level.levelgen.NoiseBasedChunkGenerator; import net.minecraft.world.level.levelgen.NoiseGeneratorSettings; import java.util.List; import java.util.OptionalLong; public class ModDimensions { public static final ResourceKey<LevelStem> LUSTRIA_KEY = ResourceKey.create(Registries.LEVEL_STEM, ResourceLocation.fromNamespaceAndPath(Lustria.MOD_ID, "lustriadim")); public static final ResourceKey<Level> LUSTRIA_LEVEL_KEY = ResourceKey.create(Registries.DIMENSION, ResourceLocation.fromNamespaceAndPath(Lustria.MOD_ID, "lustriadim")); public static final ResourceKey<DimensionType> LUSTRIA_DIM_TYPE = ResourceKey.create(Registries.DIMENSION_TYPE, ResourceLocation.fromNamespaceAndPath(Lustria.MOD_ID, "lustriadim_type")); public static void bootstrapType(BootstapContext<DimensionType> context) { context.register(LUSTRIA_DIM_TYPE, new DimensionType( OptionalLong.of(12000), // fixedTime false, // hasSkylight true, // hasCeiling false, // ultraWarm false, // natural 1.0, // coordinateScale true, // bedWorks false, // respawnAnchorWorks -64, // minY 256, // height 256, // logicalHeight BlockTags.INFINIBURN_OVERWORLD, // infiniburn BuiltinDimensionTypes.OVERWORLD_EFFECTS, // effectsLocation 0.0f, // ambientLight new DimensionType.MonsterSettings(false, false, ConstantInt.of(0), 0))); } public static void bootstrapStem(BootstapContext<LevelStem> context) { HolderGetter<Biome> biomeRegistry = context.lookup(Registries.BIOME); HolderGetter<DimensionType> dimTypes = context.lookup(Registries.DIMENSION_TYPE); HolderGetter<NoiseGeneratorSettings> noiseGenSettings = context.lookup(Registries.NOISE_SETTINGS); NoiseBasedChunkGenerator wrappedChunkGenerator = new NoiseBasedChunkGenerator( new FixedBiomeSource(biomeRegistry.getOrThrow(Biomes.BEACH)), noiseGenSettings.getOrThrow(NoiseGeneratorSettings.CAVES)); NoiseBasedChunkGenerator noiseBasedChunkGenerator = new NoiseBasedChunkGenerator( MultiNoiseBiomeSource.createFromList( new Climate.ParameterList<>(List.of(Pair.of( Climate.parameters(0.0F, 0.0F, 0.0F, 0.0F, 0.0F, 0.0F, 0.0F), biomeRegistry.getOrThrow(Biomes.BEACH)), Pair.of( Climate.parameters(0.1F, 0.2F, 0.0F, 0.2F, 0.0F, 0.0F, 0.0F), biomeRegistry.getOrThrow(Biomes.BIRCH_FOREST)), Pair.of( Climate.parameters(0.3F, 0.6F, 0.1F, 0.1F, 0.0F, 0.0F, 0.0F), biomeRegistry.getOrThrow(Biomes.OCEAN)), Pair.of( Climate.parameters(0.4F, 0.3F, 0.2F, 0.1F, 0.0F, 0.0F, 0.0F), biomeRegistry.getOrThrow(Biomes.DARK_FOREST)) ))), noiseGenSettings.getOrThrow(NoiseGeneratorSettings.CAVES)); LevelStem stem = new LevelStem(dimTypes.getOrThrow(ModDimensions.LUSTRIA_DIM_TYPE), noiseBasedChunkGenerator); context.register(LUSTRIA_KEY, stem); } } minecraft version is 1.20.1
