A Hardcore Inventory Progression & Encumbrance Overhaul for Minecraft

What if inventory space had to be earned instead of being given for free?

SlotZero transforms Minecraft’s inventory into a survival progression system where every slot matters. Start with almost nothing, craft progression equipment to expand your carrying capacity, and manage realistic item weight while surviving in a much harsher world.

Designed for survival-focused players, hardcore worlds, and modpacks, SlotZero makes inventory management a core part of gameplay progression.

🎒 Inventory Progression

In SlotZero, inventory space is part of progression.

Players no longer begin the game with a fully unlocked inventory. Early survival becomes far more strategic as you slowly build your carrying capacity through crafted progression equipment.

Progression Equipment Includes:

• 👝 Starter Pouches
• 🧰 Toolbelts
• 🎒 Backpacks

Each upgrade expands how much you can carry and changes how you approach:

• mining
• exploration
• gathering
• combat
• long-distance travel

Inventory progression is fully integrated into survival gameplay rather than acting as simple extra storage.

⚖️ Dynamic Weight & Encumbrance System

Every item in your inventory has weight.

Carrying too much will gradually encumber the player and affect movement, forcing you to make meaningful decisions about what to bring on adventures.

Encumbrance Effects Include:

• slower movement
• reduced mobility
• survival penalties from excessive burden
• inventory management becoming part of survival strategy

Heavy materials like stone, metal, and ores quickly become difficult to transport without proper preparation.

🧠 Intelligent Weight Calculation

SlotZero features an advanced recipe-aware weight engine.

Instead of manually assigning every item a random value, the system automatically calculates weights using:

• crafting recipes
• recursive material relationships
• refining/smelting logic
• fallback heuristics for unknown modded items

This allows the mod to remain highly compatible with large modpacks and heavily modded environments.

Examples:

• Gold Blocks correctly weigh the same as 9 Gold Ingots
• Smelting removes a small amount of impurity weight
• Backpacks calculate the weight of everything stored inside them

🛠️ Built for Multiplayer & Modpacks

SlotZero was designed with long-term compatibility and multiplayer support in mind.

Features Include:

• multiplayer-safe synchronization
• server-authoritative inventory restrictions
• automatic modded item weight generation
• configurable JSON weight overrides
• recursive backpack weight handling
• debugging & balancing tools for modpack developers

The mod is designed to work well in:

• hardcore survival servers
• progression-focused modpacks
• immersive gameplay setups
