Stack Manager (Fabric/NeoForge)

# Stack Manager Configurable stack sizes (vanilla + mods) A lightweight server-side mod that generates a config with all items (vanilla + modded) and lets you set the max stack size per item. Works in singleplayer (integrated server) and on dedicated servers. ## Features - Generates config/stackmanager_items.json with every registered item. - Per-item stack limits you can edit at any time. - Auto-adds new items from newly installed mods on startup/reload. - Safe network cap = 99 to avoid protocol/NBT issues. - Optional in-game commands (enabled when Fabric API is present). ## Commands (optional, require Fabric API) _/stackmanager reload_ — reload the config and append any missing items. _/stackmanager set <id> <value>_ — set a new limit (clamped to 99). _/stackmanager set <id> default_ — restore the game/mod default (clamped to 99). Without Fabric API the mod still works; edit the file and restart (or reload using your preferred method). ## Config file Path: config/stackmanager_items.json ``` { "formatVersion": 1, "items": { "minecraft:acacia_button": 64, "minecraft:oak_planks": 99 } } ``` - Keys are full item IDs (namespace:item). - Values are clamped to 1–99 at load time. ## Handy editor shortcuts (VS Code / most editors; Windows/Linux = Ctrl, macOS = Cmd unless noted) ### Format document: Shift+Alt+F (Win/Linux) · Shift+Option+F (macOS) - Find / Replace: Ctrl+F / Ctrl+H · Cmd+F / Cmd+Alt+F -Select next occurrence (multi-cursor): Ctrl+D · Cmd+D - Go to line: Ctrl+G · Cmd+G - Select word / line: Ctrl+W (word) / Ctrl+L (line) · Option+Shift+→/← or Cmd+L (macOS) ### Tips - Keep IDs alphabetized for easier diffs. - Use regex replace in Ctrl+H to mass-edit values. - After editing, run /stackmanager reload (if commands available) or restart the world/server to apply changes. ## Compatibility & limits - The mod enforces limits on the server; clients don’t need the mod (unless other mods require it). - Items with different NBT (custom names, enchantments, damage, etc.) never stack, by vanilla rules. - Most vanilla and modded GUIs respect these limits. If a specific mod screen still caps at 64/99, report it—small per-screen patches are possible. - Values above 99 are intentionally reduced to 99 to keep networking stable. ## Requirements (https://modrinth.com/mod/fabric-api): optional but recommended for better experience (enables /stackmanager commands and smoother reloading). ## Recommended usage - Install (https://modrinth.com/mod/fabric-api) (recommended, not required) to use in-game commands and improve quality of life. - Edit values directly in the config file before starting a world/server. Command-based changes—especially without (https://modrinth.com/mod/fabric-api)—can be cumbersome and may require restarts or extra steps. ## Ideas for using the mod - Potions: Easier: set potions to 16 or 32 per slot ``` minecraft:potion: 16 minecraft:splash_potion: 16 minecraft:lingering_potion: 8–16 ``` Benefit: fewer inventory trips during raids, mining, and boss fights. Note: Potions carry NBT (effect type). Only identical potions stack. ### Other quick ideas - Builder / mega-projects (QoL): - Blocks (stone, planks, glass, terracotta) 99; food 64–99; firework_rocket 64–99. - Exploration / Elytra: Rockets 16 (harder) or 64–99 (easier); Ender Pearls 16–32 (easier) or 8 (harder). - Combat / PvE: arrow 99; snowballs/eggs 64–99 for events/minigames. - Economy / survival challenge: Ores/ingots 16; ore blocks 8; pearls/snowballs 8 to curb spam ## FAQ - How do I find an item ID? Enable advanced tooltips with F3 + H, then hover the item: you’ll see namespace:item. - Can I set 9999? No. For network safety the effective cap is 99. - Singleplayer or server? Both. In singleplayer, drop the mod into mods/. On a dedicated server, only the server needs the mod.
