Item type

Hello,
I'm developing a showcase plugin and I'm having a problem with item that have many types like wood, wool, etc.
How can I differentiate them?

PHP:

    public static void makeACase(Integer item, Block b, World w, MaterialData data) {
        if (showcases.containsKey(b)) { delCase(b); }
 
        Location targetloc = b.getLocation();
        targetloc.setY(targetloc.getY() + 1.0D);
        targetloc.setX(targetloc.getX() + 0.5D);
        targetloc.setZ(targetloc.getZ() + 0.5D);
        Block target = w.getBlockAt(targetloc);
        
        if (target.getTypeId() != 0){ target.setTypeId(0); }
 
        ItemStack i = new ItemStack(item.intValue());
        i.setData(data);
        Entity drop = w.dropItem(targetloc, i);
        drop.setVelocity(new Vector(0, 0, 0));
 
        showcases.put(b, drop);
    }
    
    public void makeCase(Player p, Block b) {     
       Integer item = Integer.valueOf(p.getItemInHand().getTypeId()); if (item.intValue() < 1) item = Integer.valueOf(332);
       ItemStack i = new ItemStack(item.intValue());
       MaterialData data = i.getData();
       makeCase(p, b, item, i, data);
    }
    
    public void makeCase(Player p, Block b, Integer item, ItemStack i, MaterialData data) {
        World w = p.getWorld();
        Boolean rep = Boolean.valueOf(false);
        if (showcases.containsKey(b)) {
            delCase(b);
            rep = Boolean.valueOf(true);
        }
        
        Location targetloc = b.getLocation();
        targetloc.setY(targetloc.getY() + 1.0D);
        targetloc.setX(targetloc.getX() + 0.5D);
        targetloc.setZ(targetloc.getZ() + 0.5D);
        Block target = w.getBlockAt(targetloc);
 
        if (target.getTypeId() != 0) { target.setTypeId(0); }
       
        i.setData(data);
        Entity drop = w.dropItem(targetloc, i);
        drop.setVelocity(new Vector(0, 0, 0));
        
        showcases.put(b, drop);
 
        Location bLoc = b.getLocation();
        Object[] pvars = { Integer.valueOf(bLoc.getBlockX()), Integer.valueOf(bLoc.getBlockY()), Integer.valueOf(bLoc.getBlockZ()), b.getWorld().getName(), item, data};
        backup.put(b.toString(), pvars);
        saveMap(backup, PlayerListener.mainDirectory + File.separator + "showcases.bin");
 
        if (!rep.booleanValue()) p.sendMessage("Showcase created!"); else p.sendMessage("Showcase replaced!"); 
    }


Thanks.

 

When you're dealing with different types of a certain material, you need to familiarize yourself with the data values for that item. Here is a list of all materials in Minecraft, with their respective data values.

Now you need to implement the data values, so let's make an ItemStack containing red wool:

Code:java

ItemStack redWool = new ItemStack(Material.WOOL, 5, (short) 0, (byte) 14);

The (byte) 14 at the end of the constructor is the data value.

 

Thanks.
But how I can get the material id form object?
