So, i've decided to make a new record disc for Minecraft. I watched some of tutorials, made this out.

 

Main class file:

public static final Item recordValve = (new HLItemRecord(1450, "valve")).setUnlocalizedName("record");

 

MyItemRecord File( i had to make that one, because of protection on ItemRecord file:

 

 

package halflifemod.main;

import cpw.mods.fml.relauncher.SideOnly;

import java.util.HashMap;
import java.util.List;

import net.minecraft.item.ItemStack;
import net.minecraft.util.Icon;
import net.minecraft.world.World;

public class HLItemRecord extends Item
{
    /** List of all record items and their names. */
    private static final Map records = new HashMap();

    /** The name of the record. */
    public final String recordName;

    public HLItemRecord(int par1, String par2Str)
    {
        super(par1);
        this.recordName = par2Str;
        this.maxStackSize = 1;
        this.setCreativeTab(mod_HalflifeMod.misc);
        records.put(par2Str, this);
    }

    @SideOnly(Side.CLIENT)

    /**
     * Gets an icon index based on an item's damage value
     */
    public Icon getIconFromDamage(int par1)
    {
        return this.itemIcon;
    }

    /**
     * Callback for item usage. If the item does something special on right clicking, he will have one of those. Return
     * True if something happen and false if it don't. This is for ITEMS, not BLOCKS
     */
    public boolean onItemUse(ItemStack par1ItemStack, EntityPlayer par2EntityPlayer, World par3World, int par4, int par5, int par6, int par7, float par8, float par9, float par10)
    {
        if (par3World.getBlockId(par4, par5, par6) == Block.jukebox.blockID && par3World.getBlockMetadata(par4, par5, par6) == 0)
        {
            if (par3World.isRemote)
            {
                return true;
            }
            else
            {
                ((BlockJukeBox)Block.jukebox).insertRecord(par3World, par4, par5, par6, par1ItemStack);
                par3World.playAuxSFXAtEntity((EntityPlayer)null, 1005, par4, par5, par6, this.itemID);
                --par1ItemStack.stackSize;
                return true;
            }
        }
        else
        {
            return false;
        }
    }

    @SideOnly(Side.CLIENT)

    /**
     * allows items to add custom lines of information to the mouseover description
     */
    public void addInformation(ItemStack par1ItemStack, EntityPlayer par2EntityPlayer, List par3List, boolean par4)
    {
        par3List.add(this.getRecordTitle());
    }

    @SideOnly(Side.CLIENT)

    /**
     * Return the title for this record.
     */
    public String getRecordTitle()
    {
        return "Kelly Bailey - " + this.recordName;
    }

    @SideOnly(Side.CLIENT)

    /**
     * Return an item rarity from EnumRarity
     */
    public EnumRarity getRarity(ItemStack par1ItemStack)
    {
        return EnumRarity.rare;
    }

    @SideOnly(Side.CLIENT)

    /**
     * Return the record item corresponding to the given name.
     */
    public static HLItemRecord getRecord(String par0Str)
    {
        return (HLItemRecord)records.get(par0Str);
    }

    @SideOnly(Side.CLIENT)
    public void registerIcons(IconRegister par1IconRegister)
    {
        this.itemIcon = par1IconRegister.registerIcon("hlrecord_" + this.recordName);
    }
}

 

 

 

So, i have my Disc, it spawns and everything seems ok, but my music in jukebox is not playing. Here public static final Item recordValve = (new HLItemRecord(1450, "valve")).setUnlocalizedName("record"); you see, that after item ID there is "valve" String. Its probably the name file of my song. So, i've put my song in [jars/resources/mod/streaming] and named it "valve". Still, no song for me. What else i have to do? Thats all, what i've added to my mod, anything else i have to do with it?

You should probably extend ItemRecord. BlockJukeBox may not work with another type of Item.
