MegaStacks is a Hytale server mod that increases the maximum stack size of items in player inventories and containers — making resource management smoother and less tedious.

⭐ Features

- Increases stack size for all items up to a configurable limit (default: 200)

- Per-category control — lock weapons, armor, tools, and benches to stack size 1

- Per-item overrides — set any item to any stack size with full priority

- Smart exceptions — consumables like arrows, bombs, repair kits, and potions are handled correctly out of the box

- Safe guard — values of 0 or below are automatically set to 1, preventing engine issues

- Zero performance impact — runs once at server startup, no ticking

⬇️ Installation

- Download the latest MegaStacks.jar

- Place it in your server's UserData/Mods/ folder

- Start the server — MegaStacks.json will be generated automatically

⚙️ Configuration

The file MegaStacks.json is generated automatically on first startup:

{
  "DefaultMaxStack": 200,
  "CategoryValues": {
      "Weapon_": 1,
      "Armor_": 1,
      "Tool_": 1,
      "Bench_": 1
  },
  "ItemOverrides": {}
}

DefaultMaxStack — stack limit applied to all items not covered by a category or override.

CategoryValues — stack limit per item category prefix. Set to 1 to prevent stacking, or any higher value to allow it.

ItemOverrides — stack limit per exact item ID. Takes priority over everything else.

{
  "DefaultMaxStack": 200,
  "CategoryValues": {
      "Weapon_": 1,
      "Armor_": 1,
      "Tool_": 1,
      "Bench_": 1
  },
  "ItemOverrides": {
      "Soil_Grass": 300,
      "Rock_Stone": 500
  }
}

> Changes take effect after a server restart.

🔍 Built-in Exceptions

Some items use category prefixes that don't match their actual behavior. MegaStacks handles these automatically:

| Item                                                 | Default Stack   |
|------------------------------------------------------|-----------------|
| Arrows (Weapon_Arrow*)                               | DefaultMaxStack |
| Bombs (Weapon_Bomb*)                                 | 100             |
| Darts (Weapon_Dart*)                                 | DefaultMaxStack |
| Rekindle Embers (Weapon_Spellbook_Rekindle_Embers)   | 100             |
| Repair Kits (Tool_Repair_Kit*)                       | 100             |
| Growth Potions (Tool_Growth_Potion*)                 | DefaultMaxStack |
| Trap Bait (Tool_Trap_Bait*)                          | DefaultMaxStack |
| Fishing Traps (Tool_Fishing_Trap*)                   | DefaultMaxStack |
| Feedbag (Tool_Feedbag*)                              | DefaultMaxStack |
| Fertilizer Crystal (Tool_Fertilizer_Crystal*)        | DefaultMaxStack |

These can always be overridden via ItemOverrides.
