[1.20.1] How to add your own texture for arrow

btuh · September 9, 2023

I'm creating an arrow which, for some reason, uses vanilla texture, not the one that I want it to use.

Arrow code

import net.minecraft.core.Direction;
import net.minecraft.core.particles.ParticleTypes;
import net.minecraft.nbt.*;
import net.minecraft.network.syncher.EntityDataAccessor;

import net.minecraft.world.phys.EntityHitResult;
import org.jetbrains.annotations.NotNull;

import java.util.Objects;

public class TntArrow extends Arrow implements TraceableEntity {

    private static final EntityDataAccessor<Integer> DATA_FUSE_ID
            = SynchedEntityData.defineId(TntArrow.class, EntityDataSerializers.INT);

    public TntArrow(EntityType<? extends TntArrow> entityType, Level level) {
        super(entityType, level);
    }



    public int getFuse() {
        return entityData.get(DATA_FUSE_ID);
    }

    public void setFuse(int fuse) {
        this.entityData.set(DATA_FUSE_ID, fuse);
    }


    public TntArrow(Level p_36866_, LivingEntity p_36867_) {
        super(p_36866_, p_36867_);
    }

    @Override
    protected void onHitEntity(@NotNull EntityHitResult result) {
        super.onHitEntity(result);
        var tnt = Objects.requireNonNull(EntityType.TNT.create(result.getEntity().level()));
        tnt.setPos(result.getLocation().get(Direction.Axis.X),
                result.getLocation().get(Direction.Axis.Y),
                result.getLocation().get(Direction.Axis.Z));
        tnt.setFuse(0);
        tnt.tick();
    }

    @Override
    public CompoundTag serializeNBT() {
        CompoundTag tag = super.serializeNBT();
        tag.putInt("Fuse", getFuse());
        return tag;
    }

    @Override
    public void deserializeNBT(CompoundTag tag) {
        super.deserializeNBT(tag);
        setFuse(tag.getInt("Fuse"));
    }

    @Override
    public void defineSynchedData() {
        super.defineSynchedData();
        entityData.define(DATA_FUSE_ID, 80);
    }

    @Override
    protected void onHitBlock(@NotNull BlockHitResult result) {
        super.onHitBlock(result);
        var tnt = Objects.requireNonNull(EntityType.TNT.create(level()));
        tnt.setPos(result.getLocation().with(Direction.Axis.Y, result.getLocation().y + 1));
        tnt.setFuse(0);
        tnt.tick();
        discard();
    }

    @Override
    public void tick() {
        super.tick();
        int fuse = getFuse();
        setFuse(--fuse);
        if (fuse <= 0) {
            discard();
            if(!level().isClientSide) {
                var tnt = Objects.requireNonNull(EntityType.TNT.create(level()));
                tnt.setPos(getX(), getY(), getZ());
                tnt.setFuse(0);
                tnt.tick();
            }
        } else {
            updateInWaterStateAndDoFluidPushing();
            if (level().isClientSide) {
                level().addParticle(ParticleTypes.SMOKE,
                        this.getX(), this.getY() + 0.5D,
                        this.getZ(), 0.0D, 0.0D, 0.0D);
            }
        }
    }


}

        int enchant = EnchantmentHelper.getTagEnchantmentLevel(INFINITY_ARROWS, bow);
        return enchant > 0 && this.getClass() == TntArrowItem.class;
    }
}

Any ideas?

That seems like it's not properly overriding the texture, check the code for the arrow and see if you are doing everything right. Just ctrl click on Arrow from extends Arrow and it should show you it. Or you could get it via mcp reborn at https://github.com/Hexeption/MCP-Reborn

Ok, what exactly should I override?

btuh · September 10, 2023

I made some experiments and I saw that only spectral arrow spawns with id "minecraft:spectral_arrow". Every other arrow, including my, spawns with id "minecraft:arrow". Is it possible to fix it someway?

btuh · September 10, 2023

Maybe I should extend AbstractArrow class instead of Arrow class like the SpectralArrow class does?

Okay, but I still don't know how to connect the renderer and model

btuh · September 11, 2023

hi?

btuh · September 11, 2023

Now I have the correct texture, but it doesn't render correctly
