Hi,

 

I want to make a chest "item"

 

that gives many things like EWS with chance to get (15%), EAS with chance to get (30%)

 

i need it really soon is there any code shared for it ?

 

i tried to find an item that has the same idea, i found "Great adventurer's treasure sack" so i copy the code and do the same

 

but this is the only thing i found, what means i couldn't find the drop of the item

 

 

 

 

btw i'm using l2 ro team fandc

Did you try to open this sack in game? It might be one of the items that does not have any extractable items. You can copy the code from any other package-sack that actually gives you some items.

or

You could add your custom item handler to your item (something i like to do).

Take a look at this example (l2jServer high five):

 

Quote

<item id="21888" type="EtcItem" name="Attribute Crystal Box">
        <set name="icon" val="BranchSys.icon.br_lucky_bag_box_i00" />
        <set name="material" val="PAPER" />
        <set name="is_stackable" val="true" />
        <set name="handler" val="AttributeCrystalBox" />
    </item>

 

now in data\scripts\handlers\itemhandlers\AttributeCrystalBox.java:

 

Quote

 

public class AttributeCrystalBox implements IItemHandler
{
    private static final int[] CRYSTALS =
    { 

         9552,9553,9554,9555,9556,9557

    };
    
    @Override
    public boolean useItem(L2Playable playable, L2ItemInstance item, boolean forceUse)
    {
        if (item == null)
        {
            return false;
        }
        if (item.getId() != 21888) // Attribute crystal box id
        {
            return false;
        }
        L2PcInstance player = playable.getActingPlayer();
        if (player == null)
        {
            return false;
        }
        int cry = CRYSTALS[Rnd.get(CRYSTALS.length)]; //Pick a random cry, with same chance
        player.destroyItem("Attribute Box", item, 1, player, true);
        player.addItem("Attribute box", cry, 1, null, true);
        return true;
    }
}

 

 

 

In my example, all items have the same chance. You could make your own play with them, as you like.

Hi mister,

 

look what i did

 

<etcitem id="94322" name="Golden Chest">

    <set name="class" value="EXTRACTABLE"/>

    <set name="crystal_type" value="NONE"/>

    <set name="icon" value="icon.etc_treasure_sack_1_i00"/>

    <set name="stackable" value="true"/>

    <set name="type" value="OTHER"/>

    <capsuled_items>

      <capsuled_item id="6577" min_count="1" max_count="2" chance="15.0"/>

      <capsuled_item id="6578" min_count="5" max_count="5" chance="15.0"/>

      <capsuled_item id="14052" min_count="300" max_count="500" chance="15.0"/>

      <capsuled_item id="57" min_count="50000000" max_count="50000000" chance="100.0"/>

    </capsuled_items>

  </etcitem>

</list>
 

but i want to know how can i make a group of items

 

for example i want to put soul crystal 16 ( red blue green )

 

i want to put their chance 3% and get random one of them

 

how can i do that ?

[melron]

the structure of it does not allow you to do the thing you want. either you need custom code for the specific item or edit the way of parsing these type of boxes

Despite @melron's answer.

 

As far as i remember, this cannot be done they way you are trying do (even if it is a great approach).

 

So, you can go my way, with a custom item handler for each item (will be a pain in the ass if you want to use it for many items, but easy for 1-2 items so can play around with a lot of stuff).

 

Finally, the way i see things now, in order to make it generic and make it work for a lot of items, you would typically need:

-1 new object or edit L2ExtractableProduct and add it a kind of field "groupId", which will support the group.

-Then make the parser, parse the groups (in case of edit L2ExtractableProduct, you have to make it accept 4 arguments, in order not to screw the already existing capsuled items)

-A new handler for these items in order to group the items. (I would leave "ExtractableItems" handler as it is)

 

 

Since i gave you the example, i will give you an example how to make groups in the handler.

So now you are able to add whatever you want.

 

P.S: Please ignore any syntax errors, everything made in notepad :P

            super();
            this.id = id;
            this.minCount = minCount;
            this.maxCount = maxCount;
            this.groupId = groupId;
        }

    }
}

 

So now you are able to add whatever you want.

 

P.S: Please ignore any syntax errors, everything made in notepad :P

Check the console for any errors. The attribute "chance" might be incorrect value.
