Inertia!
by asa0x
Inertia smooths the camera for Fabric players on Minecraft 1.20.1, damping stairs, landings, falls and mouse jitter so view changes feel less abrupt.
What it does
Inertia replaces the rigid camera movement of vanilla Minecraft with smoothed motion. Walking up stairs, slabs and blocks no longer snaps the view upward; the camera glides through each step instead. Falls are softened as the view transitions downward, and landings settle gently rather than jolting to the ground.
Mouse input is interpolated separately from the render rotation, which reduces the stepping feel that appears on high-DPI mice or at low framerates while keeping aim accurate. The author describes the aim is meant for players sensitive to motion sickness, eye strain or jarring camera changes, and the mod is designed around accessibility and comfort. It runs on the client alone, and Fabric API is required alongside it, with Mod Menu optional for its settings screen.
The mod is published for Fabric only, with a single build, 1.0.0 for 1.20.1, released on 2025-12-13. It is licensed under All rights reserved and is not open source.
Key features
Smoothed stair stepping
Camera movement over stairs, slabs and blocks is eased out, removing the rapid upward snap of vanilla movement.
Softened descents
Height changes when dropping down are blended across frames, so falling feels less abrupt.
Cushioned landings
After a fall the camera settles toward the ground gradually, making movement feel continuous rather than jagged.
Independent mouse interpolation
Mouse movement is interpolated apart from the render rotation to reduce stepping on high-DPI mice and low framerates.
Camera smoothing controls
Filters for vertical motion and general view stabilization let players decide how much smoothing the camera handles.
