📦 CubeSense — Sulfur Cube Behavior Preview
Know what a Sulfur Cube will do before you feed it.
CubeSense is a lightweight, client-side Fabric mod for Minecraft Java 26.2 that displays a clean, non-intrusive preview panel whenever you aim your crosshair at a Sulfur Cube while holding a block or item.

✨ Features
- Target-Aware HUD: Automatically appears only when aiming directly at a Sulfur Cube. Disappears the moment you look away.
- Instant Archetype Preview: Tells you the exact physical behavior the cube will take on before feeding it (e.g.,
BOUNCY,SLIDING,STICKY,EXPLOSIVE,HOT). - Data-Driven & Datapack Friendly: Reads directly from Minecraft 26.2's native
#minecraft:sulfur_cube_archetype/*item tags. Any item added to vanilla archetype tags via custom datapacks will work automatically without mod updates. - Smart Edge-Case Handling:
- Not Absorbable: Clearly flags items that cannot be fed to Sulfur Cubes.
- Custom Archetypes: Identifies custom datapack items without making false guesses.
- Vanilla Explosives: Correctly handles vanilla TNT's dedicated explosive behavior.
- 100% Client-Side: No server installation required. You can join vanilla servers and multiplayer realms with full functionality.
- Zero Bloat & Peak Performance: No background entity scanning, no network packets, and zero performance impact.
