Solved Creating and setting items in a config list

I'm trying to create a rewards system so that when a player completes an achievement they receive the items in the config list. I don't necesarilly know how to set ItemStacks into a list however I do know how to set a specific item on one line and retrieve it like so

Code:

            player.getInventory().addItem(new ItemStack(Material.getMaterial(config.getString("Config.Rewards.Item").toUpperCase()), config.getInt("Config.Rewards.Quantity")));

However I would like to create a list of items and give the players all the items in that list?

Code:

        config = YamlConfiguration.loadConfiguration(file);
     
        config.getList("Config.Rewards.Tier1.Task1");
     
        player.getInventory().addItem(new ItemStack(Material.REDSTONE, 8));
        player.getInventory().addItem(new ItemStack(Material.IRON_INGOT, 3));

Example:

Code:

Rewards:
     - diamond
          - 5
     - iron_ingot
          - 8
     - iron_hoe
          - 1

 

• Make a for-loop and getKeys(false)
• Make another for-loop to get the amounts

Code:

.. for(item : getKeys(false).. {
   .. for(String amount : getStringList("Rewards." + item + ".amount").. {
              addItem(new Item(Material.matchMaterial(item), amount)

Your config would look like this:

Code:

Rewards:
  Diamond:
    - 1
  Iron_Ingot:
    - 4

   etc

By the way, this code isn't exact and it won't work by just copy and pasting. It is just to give you an idea. Hope I helped!

I don't know why you would want the config to have a list for the amounts if you only have one 'amount' per item stack, but meh..

 

Thanks. The reason as to why I want quantities in the config is because I want the quantities of the item to be changed. So lets say you want to give 4 diamonds instead of 1. You would be able to change the quantity in the config.

 

If your problem has been solved, mark this thread as solved.

 

Haven't tried it yet

What does getKeys do?
@mehboss

I currently have this however matchMaterial is red

Code:

        List<?> Items = config.getList("Config.Rewards");
        for (int i = 0; i < Items.size(); i++) {
            ItemStack Item = (ItemStack) Items.get(i);
            if (Item == null) {
                continue;
            }
            player.getInventory().addItem(Material.matchMaterial(Items), 1);
        }

 

You didn't even make the for-loops. getKeys will get every first string in a config section that you specify, if you do specify one.

I've gotten it to work using

Code:

            ItemStack[] t2t1 = {(new ItemStack(Material.IRON_AXE, 1)), (new ItemStack(Material.IRON_INGOT, 3))};

            config.set("Config.Tier2.Task1.Rewards", t2t1);

However in the config it shows up as

Code:

    Task1:
      Need: 20
      Rewards:
      - ==: org.bukkit.inventory.ItemStack
        type: IRON_AXE
      - ==: org.bukkit.inventory.ItemStack
        type: IRON_INGOT
        amount: 3

How do I get rid of the - ==: org.bukkit.inventory.ItemStack so that I don't have to copy that plus the type to add a new item to the list?

 

If you're gonna be storing custom items (w/ custom names/lores), instead of storing the whole item all together, store it's display name , lore, enchantments seperately, and then get the objects and compile them into 1 itemMeta seperately,

Instead of storing he itemstack, store the material name, and generate a new itemstack

 

You said you wanted to get a string from config, not set.. this code was close:

It should be this:

Code:

for (String items : getConfig.getString("Items")) {
     for (String amount : getConfig.getString(Items + ".Amount")) {
          player.getInventory().addItem(Material.matchMaterial(items), amount);
    }
}

Code:

Items:
  Diamond:
    Amount: 1
  Iron_Ingot:
    Amount: 1

 

@raunak114
I'm not trying to save any item meta of the items. I tried making a material array list however it didn't want to work

 

What would you need this for?

 

Sorry, replied to the wrong person

 

@plisov

Were you directing that message towards me? Here's a post big post to hopefully get things cleared up. It has been way too long and this post should already be solved.

You want to specify items in the config... As asked in this thread. Here is an example config below to have better understanding.

Example Config:

Code:

Items: //this is a normal configuration section
  IRON_INGOT: //this is an item material
    Amount: 1 //string says it all
  REDSTONE:
    Amount: 1
  DIAMOND:
    Amount: 1

• So basically to go about getting all the materials in this configuration section. First, you want to make a for-loop to loop through all the keys, in this case, there are 3 keys: IRON_INGOT, REDSTONE, & DIAMOND.
• Once we make the for-loop, we want to get the amount. To do this, we make another for-loop and get the string "Amount" for every key in the configuration section.
• After that, we make each one of those an itemstack.
• Next, we can do whatever we want with those, add it to an array, re-save it, add the itemstack to the player's item, etc..
• In this case, we will add it to the player's inventory, just because this is an example.

Code:

1.
        for (String item : getConfig().getConfigurationSection("Items").getKeys(false)) {

    * ^ ^ So basically, what this line does, it it returns all the keys in that section, in this case: (IRON_INGOT, REDSTONE, & DIAMOND).

2.
    if (getConfig.getInt(item + ".Amount")) {

   * ^ ^ So basically, this gets all the "Amount"'s in each key of that configuration section.

3.
            ItemStack item = new ItemStack(<MATERIAL>, <AMOUNT> //showing the parameters

       DO:
           ItemStack item = new ItemStack(Material.matchMaterial(items), amount);

     * ^ ^ What this does is sets the itemstack variable to the material + the amount of the stack. [NOTE: Materials should be fully UPPER-CASED

4.
    p.getInventory().addItem(item);

     * ^ ^ Here, since this is just a tutorial, I add each item to a player's inventory to finish this tutorial off.

I suggest learning about configuration sections if you STILL do not know how to do this. Personally, I believe I have explained this to you good enough & you should be able to get an idea of how to deal with your question/problem.

SAVING/GETTING ITEMSTACK TO/FROM CONFIG:
You can save the itemstack separately (ex. displayname, material, amount) or you can save it all together & make config ugly. Hence this is a really easy part of java, I'm not going to explain it to you, but you can find about it here:

https://bukkit.org/threads/tut-bukkits-new-fileconfiguration-api-create-a-yaml-configuration.42775/
https://bukkit.org/threads/tut-bukkits-new-fileconfiguration-api-create-a-yaml-configuration.42775/
http://bukkit.gamepedia.com/Configuration_API_Reference

To store a material from an itemstack to config you would do:

Code:

            getConfig.set(STRING, item.getType());

    ^^ Item would be the itemstack variable from above when you got the itemstack data from the config.
NOTICE: getType() > returns the material type of something, without this it will return the whole item stack.

Hope I helped! If your problem has been solved please change the thread prefix to solved. This saves us developers time when scanning the plugin development section.
