Custom Cases

🎰 Custom Cases Mod

Animated Loot Cases for Minecraft!

Open a case. Watch the CS:GO-style roulette spin. Claim your reward.

• Loot cases are 100% configurable.

✨ Features

🎮 Gameplay

• 🎰 CS:GO-style roulette — smooth two-phase easing (cubic in → exponential out)
• 🃏 Open ×5 — open five cases simultaneously in a side-by-side view
• 🔍 Case preview — left-click any case to inspect its full loot table with exact drop rates
• 🏆 Legendary broadcast — server-wide chat message and sound when a legendary item is won, synced with the exact moment the roulette stops

⚙️ Technical

• 📁 100% customizable cases — defined as JSON files in \config\CasesMod\cases\, no code required
• 🔄 Live reload — /casesmod reload instantly applies changes without restarting
• 🔒 Reward escrow — unclaimed rewards are safely stored server-side, even after disconnects
• 🛡️ Server-authoritative system — all rolls happen server-side; clients only receive animation data

🎨 Customization — \config\CasesMod\cases\

• 5 rarity tiers, each with configurable particle effects (type, count, enabled/disabled)
• Configurable spin duration, legendary sound ID, and broadcast scope (winner-only or global)
• Per-item customization :

• Name,
• Rarity,
• Drop chance (%),
• Enchantments,
• Attributes,
• CustomModelData,
• Stack size ranges,
• NBT - (CasesMod 1.1.0 and above)

🖌️ Textures

➡️ You can add, modify, or remove textures for cases and GUIs by opening the .jar file (for example with WinRAR) and navigating to:
\resources\assets\casesmod\

You can modify or add:

• case_<CaseID>.png
• case_gui_<CaseID>.png
• multi_case_gui_<CaseID>.png
• spin_overlay_<CaseID>.png

⚠️ All players must use the same modified mod version ⚠️

• Resource pack support: planned, not yet tested

💎 Rarity Tiers

📦 Adding a Case

Drop a .json file into \config\CasesMod\cases\ and run /casesmod reload (does not requires restart to apply).

{
  "caseName": "Weapon Case",
  "caseId": 3,
  "XP_price": false,
  "XP": 1,
  "Item_price": false,
  "Item": "minecraft:chest,
  "Item_count": 1,
  "Command_price": false,
  "Command": "/give %player% minecraft:chest",
  "loot": [
    { 
      "item": "minecraft:iron_sword", 
      "min": 1,
      "max": 1,
      "chance": 40, 
      "rarity": "common" 
    },
    { "item": "minecraft:diamond_sword", 
      "chance": 20, 
      "rarity": "rare",
      "enchantments": [{ "id": "minecraft:sharpness", "level": 3 }] 
    },
    {
      "item": "minecraft:diamond_sword",
      "min": 1,
      "max": 1,
      "chance": 4.76,
      "rarity": "epic",
      "displayName": "§6★ Diamond Sword ★",
      "customModelData": 1,
      "attributes": [
        { "name":"minecraft:generic.attack_damage","value": 10.0,"slot":"mainhand"},
        { "name":"minecraft:generic.armor","value": 5.0,"slot":"chest"}],
      "enchantments": [
        { "id": "minecraft:sharpness",  "level": 5 },
        { "id": "minecraft:unbreaking", "level": 3 },
        { "id": "minecraft:looting",    "level": 3 }]
    },
    {
      "item": "minecraft:chest",
      "min": 1,
      "max": 2,
      "chance": 60.76,
      "rarity": "epic",
      "NBT": "BlockEntityTag:{Items:[{Slot:0,id:acacia_fence,Count:1},{Slot:15,id:acacia_slab,Count:1}]},Enchantments:[{lvl:1,id:depth_strider}]"
    }
  ]
}

Chances do not need to total 100 — they are automatically normalized. Both "chance" and "weight" are supported.

🪤 Adding a Case in Loot Table

Drop a .json file into data/<your_mod>/loot_tables/ or use a Global Loot Modifier.

The function casesmod:set_case_id adds the NBT tags CaseID and CustomModelData to the item casesmod:case_item. The Case_ID must match a file in /config/CasesMod/cases/<Case>.json on the server.

Here: 30% chance to get Case #1, 10% chance to get Case #2.

            }

        }
      ]
    }
  ]
}

⚙️ Configuration

\config\CasesMod\CasesMod.yml (requires restart to apply):

🌟 Legendary Events

Configure in /config/CasesMod/CasesMod.yml:

legendary:
  message: "§6[CasesMod] §r{player} §6obtained §r{item} §6(Legendary)!"
  sound_enabled: true
  sound_broadcast: true   # false = only the winner hears it
