Item Blacklist

[ElitoGame]

Short Description

Some servers might have unique items, they do not want to be sold. May it be due to a story quest or just because a dupe gave some person 9 million barrier blocks. In these cases or others, you might want to stop the trade of certain items with a blacklist.

Implementation

• Create a new config file to handle the blacklist (itemblacklist.yml). Some servers might add a ton of items to this list. In that case, storing the blacklist in the standard config, would make it quite unreadable.
• The way items are defined will vary a lot, so there should be a bunch of options:

blacklist:
  # -------- Compact design: ---------
  # The material can be defined via material:name. This should use the same names as F3+H ingame, not the bukkit STONE names.
  - material:stone 
  # Using two ;; separates options. itemname and lore can be used to filter for these settings. \n equals a new line of lore. 
  # If a lore or name line starts with &- it means that the check should ignore colors. ChatColor.stripcolors()
  - material:diamond_pickaxe;;itemname:King's Axe!;;itemlore:Only wielded by\n&-the king during combat!
  # Enchantments can be defined with or without a associated level. /{level} and are separated by comma. 
  # A > or < sign can be use limit to values greater then or less then.
  - enchantments:depth_strider,feather_falling/4,unbreaking/>1,mending
  # potions work the same way as Enchantments. Durability can be a value or if it ends with % a percent value. 
  # Can be used with > or < too.
  - potions:slow_falling,resistance/<4;;durability:100%
  # Attributes consist of the syntax: name of the attribute/ value of the attribute/ operation of the attribute/ affected slots.
  # Slots are separated by the & symbol.
  # Hide flags targets the various flags to hide. Unbreakable is a boolean value, either true or false.
  - attributes:max_health/1/amount/mainhand&offhand;;hide_flags:modifiers,unbreakable;;unbrekable:true
  # -------- Readable/Comfy design: ---------
  # Items have a identifier name to find them easier.
  - item1:
    material: fishing_rod
    enchantments:
      - lure: >1
      # Level 0 equals not here at all. Level -1 equals enchantment is present with any level.
      - unbreaking: 0
    unbreakable: true

• Implement a ingame blacklist editor. /ecsadmin blacklist will show a gui list of all the blacklist filters. If a filter doesn't have a material, display a replacement item here instead (paper or structure void)
• Filters don't neccessarily need a item. When inside the blacklist gui, have a button to select a item from your inventory. Whichever item you click next in your bottom inventory will be added as a blacklisted item. You will be directed to a new window with various buttons. You can select all the item settings you want to use for the blacklist:

[Material]   [Name]     [Lore]     ...
 enabled    disabled   disabled    ...

• A shop selling a blacklisted item should still be opened when clicked, however, the buy and sell options should be disabled. Creating a shop with a blacklisted item should throw an error.
