About this Mod

Inertia!

Fluid Camera & Motion Overhaul

Mod Version
Fabric

Bring fluidity and comfort to Minecraft. Remove the rigid stiffness of vanilla movement and eliminate motion sickness.


🌊 What is Inertia?

Inertia! replaces the rigid, snapping camera of vanilla Minecraft with a silky-smooth, responsive system. It removes the harsh micro-stutters and "stair-stepping" of vanilla movement, replacing them with fluid transitions.

It operates on a simple philosophy: Gameplay should feel comfortable, not jarring.

  • Hate the screen snapping when walking up stairs? Smooth it out.
  • Tired of micro-jitters from your mouse? Filter the noise.
  • Suffer from motion sickness? Stabilize your view.

Designed with accessibility in mind, Inertia! makes Minecraft feel modern and fluid, giving you full control over how your camera handles.


🎥 Key Features

Inertia! polishes the rough edges of the game engine without sacrificing the precision you need for gameplay.

☁️ Vertical Smoothing

  • No More Stair-Stepping: The camera glides smoothly when walking up blocks, stairs, and slabs, removing the rapid "snap" effect that causes eye strain.
  • Softened Descents: Falling feels less abrupt. The camera transitions smoothly downward, removing the jarring visual disconnect of rapid height changes.
  • Cushioned Landings: Instead of snapping instantly to the ground, the camera stabilizes gently upon landing, making movement feel continuous rather than jagged.

🖱️ Input Polish

  • Fluid Aim: Mouse movement is interpolated independently of the render rotation.
  • Jitter Elimination: This eliminates the "stepping" feel of high-DPI mice and low framerates while ensuring your aim remains accurate.
  • Crosshair Sync: Unlike cinematic cameras that misalign your aim, Inertia! ensures your crosshair always interacts with the block you are looking at.

🤢 Motion Sickness Relief

  • Bobbing Separation: Specifically designed tools allow you to decouple head bobbing (the camera shake) from hand bobbing (the walking animation).
  • Jagged Terrain: A custom smoothing curve removes the harsh camera snaps when navigating rough terrain.

⚙️ Configuration & Presets

Inertia! is fully configurable via Mod Menu. Choose from tuned presets or customize every value to your liking.

☁️ Smooth (Recommended)

Optimized for a fluid, modern feel. It eliminates micro-jitters and smooths out the harsh "stair-stepping" of vanilla movement. Perfect for players prone to motion sickness.

🍦 Vanilla

Returns the camera to standard Minecraft behavior while keeping the mod active, allowing you to selectively enable specific features like "Bobbing Separation" manually.

🔧 Custom

Want something specific? Inertia! gives you full control. Tweak vertical rise/fall speeds, mouse smoothing, and bobbing logic to create your perfect setup.
