Crosshair Bobbing for NeoForge 1.21.1
Crosshair Bobbing is a client-side mod that makes the crosshair respond dynamically to player movement, mining, block breaking, block placement, and other in-game actions.
The latest major update, JellyV4, introduces our brand-new Jelly Animation Engine — a complete redesign of the entire crosshair animation system.
JellyV4 Features
- Brand-new JellyV4 Animation Engine
- Completely redesigned animation logic and internal architecture
- Smoother, softer, and more elastic crosshair motion
- Reworked mining, block-breaking, and block-placement feedback
- More natural transitions and more satisfying rebound effects
- Improved animation state management and trigger handling
- Improved stability in complex modded environments
- All original features retained with a significantly improved animation experience
JellyV4 is not a simple patch. It is a full redesign of the entire crosshair animation system, powered by our new Jelly Animation Engine.
This project will continue to receive updates for NeoForge 1.21.1.
