About this project

What does LIFE-XP Challenge add?

LifeXP Challenge: Survive to Evolve

What if your experience levels directly dictated your physical capabilities? LifeXP Challenge replaces the static vanilla attributes with a dynamic, highly configurable progression system tied directly to your XP level.

Originally designed as a standalone hardcore challenge, this mod is built with complete flexibility in mind, making it a perfect foundation for custom modpacks.

Core Mechanics:

Zero-Level Penalty: Start weak. By default, spawning in a new world grants you only 0.5 hearts and significantly reduced movement speed.
Dynamic Progression: Earning experience doesn't just allow for enchanting anymore. Your max health, attack speed, movement speed, and 10 other attributes scale automatically as your level increases.
Zero-Tick Updates: Attributes calculate and apply instantly in the background without lag or requiring a relog.

Built for Modpack Creators (YACL Integration): The entire scaling system is in your hands via Yet Another Config Lib (YACL).

Custom Caps: Define your own maxLevel cap (e.g., 50, 100, or 10,000).
Interpolation Curves: Set custom startValue (Lv. 0), midValue (Lv. 50%), and endValue (Max Lv.) for 13 different vanilla attributes.
Built-in Presets: Instantly switch between "Hardcore" (weak start), "Vanilla+" (balanced late-game buffs), or "God Mode" configurations.

Supported Attributes: Max Health, Movement Speed, Attack Damage, Attack Speed, Armor Toughness, Knockback Resistance, Block/Entity Interaction Range, Block Break Speed, Sneaking Speed, Submerged Mining Speed, Sweeping Damage Ratio, Safe Fall Distance.

Required Dependencies: Fabric API, Yet Another Config Lib (YACL).
