Solved Repeating Task Help.

Hi, I'm working on an RPG-style plugin. I have made it so that every second 1 hunger is regenerated (half a hunger thing techincally, as full would be 20). I am trying to make it so that if a player is wearing a leather helmet with a display name that contains "Mana Boost" then it will give + 8 hunger. I chose +8 to be able to easily see if it's working or not. In my code you'll also see it checking for an apple, this was to ensure that having items in your inventory can affect how much hunger you get. This works.

However for the helmet I get an error in my console: http://hastebin.com/upayofexoz.avrasm
(Line 51 is line with the words "Mana Boost" below.)
I do not get any errors in eclipse.

Code:

    @Override
    public void onEnable() {
        PluginManager pm = getServer().getPluginManager();
        pm.addPermission(wandsDrain);
        Bukkit.getServer().getPluginManager().registerEvents(this, this);
        this.getServer().getScheduler().scheduleSyncRepeatingTask(this, new Runnable() {
              public void run() {
                  Player[] players = Bukkit.getServer().getOnlinePlayers();
                  for (int i = 0; i < players.length; i++) {
                      players[i].setFoodLevel(players[i].getFoodLevel() + 1);
                      if (players[i].getInventory().getHelmet().getItemMeta().getDisplayName().contains("Mana Boost")) {
                          players[i].setFoodLevel(players[i].getFoodLevel() + 8);
                      }
                     
                      if (players[i].getInventory().contains(Material.APPLE)) {
                          players[i].setFoodLevel(players[i].getFoodLevel() + 2);
                      }
                     
                    }
              }
            }, 0L, 20L);
    }

I hope someone is able to help me. If you need any more clarification just let me know

 

@oceantheskatr might be wrong here, can't check over myself at the moment, but I believe display name isn't saved in item meta, trying changing it to getHelmet().getDisplayName().

 

@oceantheskatr Check of they have a helmet and it has an item meta

 

Thank you for your reply, though it didn't seem to work.

I have added this:

if (players.getInventory().getHelmet().hasItemMeta() == true) {

How would I check to ensure the item meta is "Mana Boost"?

 

@oceantheskatr The item meta is never equal to "Mana Boost". First you check if it has the meta, like you have done. Then, if it does, you get the item meta and get the display name.

 

YES! Thank you so much! This worked perfectly

Also thank you to @bwfcwalshy and @BizarrePlatinum for your contributions to help me

 

@oceantheskatr No problem
