Solved How to get specific item from player inventory

So im am trying to make a plugin about a sword that is called Thursty Blade!
This sword is thirsty for blood and it gets blood by hitting players and(or) creatures!
The amount of blood it has is stored in the item's lore!

Now I am trying to make it so every X seconds the blade loses X blood from its lore!

So far i have made an RepeatingTask but i need real help!
@aninsanellama maybe you can help me again?

How do I get the ThirstyBlade item from the players inventory and then change its lore please help!

Here is my code:

Code:java

    @SuppressWarnings("deprecation")
    public void onEnable(){
        getServer().getPluginManager().registerEvents(this, this);
 
        saveDefaultConfig();
        if(getConfig().getBoolean("gettingthirsty") == true){
 
        BukkitScheduler scheduler = getServer().getScheduler();
        scheduler.scheduleAsyncRepeatingTask(this, new Runnable(){
 
            @Override
            public void run() {
                for(Player p : getServer().getOnlinePlayers()){
                    //itemstack here
                    ItemStack tb = new ItemStack(Material.IRON_SWORD);
 
                    if(p.getInventory().contains(tb) && tb.getItemMeta().getDisplayName().equals(ChatColor.RED + "" + ChatColor.BOLD + "Thirsty Blade")){
                        //Player has the blade
 
                        //How do i get the slot ID of the blade!
                        int tbid = tb.getData();
 
 
                        List<String> lore = p.getInventory().getItem(tbid).getItemMeta().getLore();
                        String loreLine = lore.get(3);
 
                        String splitted = loreLine.split(ChatColor.RESET + "" + ChatColor.GRAY +"Blood: " + ChatColor.WHITE)[1];
                        splitted        = splitted.split("/")[0];
 
                        int blood2 = Integer.parseInt(splitted) - getConfig().getInt("thirstvalue");
                        if(blood2 <= 0){
                            blood2 = 0;
                        }
 
                        ItemMeta tb2Meta = p.getInventory().getItem(tbid).getItemMeta();
                        tb2Meta.setDisplayName(ChatColor.RED + "" + ChatColor.BOLD + "Thirsty Blade");
                        tb2Meta.setLore(Arrays.asList(ChatColor.RESET + "" + ChatColor.GRAY +"Give that blade some blood",
                                            ChatColor.RESET + "" + ChatColor.GRAY +"and it will become stronger!",
                                            "",
                                            ChatColor.RESET + "" + ChatColor.GRAY +"Blood: " + ChatColor.WHITE + blood2 + "/100"));
 
                        p.getInventory().getItem(tbid).setItemMeta(tb2Meta);
 
 
 
 
 
                    }
                    else{
 
                    }
                }
            }
 
        }, 0L, getConfig().getInt("thirstdelay")*20L);
        }
        else{
 
        }
    }
 

 

Didn't play with inventories for long time now but you can just loop through the content of inventory and if items item meta is same change it?

 

BaHeTo0 don't use async tasks with methods that aren't thread safe (which includes most of the API)

 

I still need some example code please

 

BaHeTo0
Loop through player's inventory -> Check if items is not null and if it's the ItemStack you want -> Change lore.

 

Gater12 example code please

 

BaHeTo0 which part you don't know how to do?

 

BaHeTo0
Use enhanced for loop. Example is in oracle's tutorial on for statement:
http://docs.oracle.com/javase/tutorial/java/nutsandbolts/for.html

 

Necrodoom how to create the loop that loops through inventory for(ItemStack i : p.getInventory .... ) something?

 

BaHeTo0 see http://jd.bukkit.org/rb/apidocs/org/bukkit/inventory/Inventory.html#getContents()

 

Necrodoom danke ... i mean Thank you
