Hi, Jones here from BPO. In this post I will show you how to write a simple script and explain how it works. There are 2 things in the script that I'm not sure of, so maybe someone can also confirm it to me. function ItemUse_KylinChest ( role , Item ) local cha = TurnToCha ( role ) --// define [cha] as the character (?) local cha_type = GetChaTypeID ( cha ) --// get the character's type (1 = Lance, 2 = Carsise, 3 = Phyllis, 4 = Ami) and put into definition as [cha_type] local Item_CanGet = GetChaFreeBagGridNum ( role ) -- Define [Item_CanGet] as Free Grid space in Character's Inventory. (Free Slots) if Item_CanGet <= 3 then -- If Free Slots in inventory EQUALS or LESS THAN 3, then SystemNotice(role ,"Requires 4 slots in inventory to open the Kylin Chest!") -- Initiate a System Message UseItemFailed ( role ) -- Fail to use the item. return end -- Close [if] GiveItem ( cha , 0 , 825 , 1 , 0 ) -- Give Item to character, 0, 825 (Item ID), 1, 0 GiveItem ( cha , 0 , 826 , 1 , 0 ) -- Give Item to character, 0, 826 (Item ID), 1, 0 GiveItem ( cha , 0 , 827 , 1 , 0 ) -- Give Item to character, 0, 827 (Item ID), 1, 0 local cha_name = GetChaDefaultName ( role ) -- Define [cha_name] as Character's name, VALUE: [GetChaDefaultName ( role )] local message = cha_name.." opens the the Kylin Chest and gets a Kylin Set!" -- Define [message] as the following message. Notice ( message ) -- Do a world-announcement (Notice) for the message. end -- Close the Function You can put this script into ItemEffect.lua in scripts>calculate>itemeffect.lua and make an item with XXXX id, then define the ItemUse_Function as ItemUse_KylinChest. eg. 7694 Kylin Chest n1755 10130016 0 0 0 0 0 0 31 0 0 0 0 0 1 1 0 1 1 0 200 -1,-2,-2,-2 0 -1,-2,-2,-2,-2,-2,-2,-2,-2,-2,-2,-2,-2,-2,-2,-2,-2,-2,-2 0 0 -1,-2,-2,-2,-2,-2,-2,-2,-2,-2 -1,-2,-2,-2,-2,-2,-2,-2,-2,-2 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0,0 0,0 0,0 0,0 0,0 0,0 0,0 0,0 0,0 0,0 0,0 0,0 0,0 0,0 0,0 0,0 0,0 0,0 0,0 0,0 0,0 0,0 0 0,0 0,0 0 0 0 0 0 0 0 0 0 ItemUse_KylinChest 0 0 0 0,0 0 0 Click to obtain the Kylin Set! 0 7694 is the Item ID Kylin Chest is the Name n1755 is the Icon After that, you can double click on the item and the function will play itself!
