Mod Name: RunFast Author: kscm Game Version: Minecraft Java Edition 1.20.1 / 1.21 Loaders: Forge 43.3.0+ (NeoForge Compatible)
Description
Tired of the vanilla sprinting speed? RunFast offers a simple yet intense mechanic: while holding the sprint key, your movement speed doubles, making exploration and travel significantly faster. However, speed comes at a cost. Your hunger drains twice as fast. Want to keep sprinting forever? Make sure you have enough steak in your inventory, or you'll slow down to a crawl!
Features
Double Sprint Speed: Greatly increases mobility for traversing terrain. Double Hunger Drain: High-speed movement demands high energy consumption. Manage your food wisely! Mechanics Note:
You cannot jump while holding the sprint key. To jump, simply release the sprint key briefly, then press jump while sprinting.
Fully Configurable: Not a fan of the mechanic? Open runfast-common.toml and set enabled = false to disable the mod entirely.
