Vitalitylogic is a vanilla-friendly survival expansion add-on that introduces a realistic and strategic daily stamina (vitality) management system. There are no custom healing items; you must carefully plan your daily activities, manage your limits, and rest to survive.

🌟 Core Features

[NEW] Custom Achievement System (V1.3): The add-on now tracks your survival life! Unlock 8 unique achievements (e.g., "Limit Break", "Workaholic", "Iron Will") by playing strategically. View your progress anytime via the main menu or the /vl:achievements command.

Daily Vitality Limit: Every action consumes your daily vitality. It fully recovers at dawn or by sleeping in a bed.

Sleep Quality (Night Owl Penalty): If you stay up all night without sleeping in a bed, your vitality will only recover up to 80%, and you cannot increase your max vitality the next day.

Dynamic Max Vitality (Use it or lose it!):

Level Up: Consume over 90% of your vitality and get a good night's sleep to increase your max capacity (+100) the next day and cure all debuffs!

Lack of Exercise: Consume less than 20% and your max capacity will decrease (-100). Consecutive lazy days will cause Slowness, and eventually "Lifestyle Diseases" (Nausea).

Inventory Weight System: Carrying too many items increases your stamina consumption! The more slots filled in your inventory, the heavier the burden. The weight multiplier is displayed on your UI (e.g., [Wt: 1.5x]). Shulker boxes are now your best friends!

Overwork & Fatigue System:

If your vitality hits 0, you will take direct damage (Overwork).

Overworking accumulates "Fatigue". The next day, you will suffer severe penalties (Slowness, Mining Fatigue, Weakness). Fatigue gradually heals by spending days without overworking.

Smart Movement & Action Detection:

Swimming (full-body workout) consumes 1.5x stamina, while sneaking reduces it to 0.5x.

Gliding with Elytra or riding animals/vehicles reduces stamina consumption to just 5%.

Teleporting (Ender Pearls, Chorus Fruit) costs 0 stamina.

⚙️ Difficulty Modes

Players can change their individual mode at any time using the setup menu (No OP required!).

Normal: Only walking/running consumes vitality. Milk can clear debuffs. Weight penalty is mild.

Hard: Moving, Combat, and Mining consume vitality. Milk CANNOT clear system debuffs (they will be forced back instantly). Weight penalty is strict.

Hardcore: Same as Hard, but the Vitality UI is completely hidden. You only get a "Morning Report" upon waking up. Weight penalty is brutal.
