Ultimate Time Stop v1.6.1 (Fabric 1.20.1)

This update is a major milestone: for the first time, I'm introducing world-generation structures and stationary clockwork pedestals to the mod. I'll admit I'm not the greatest builder out there, but I put a lot of work into making these ruins look atmospheric, fit their respective biomes, and give you rewarding places to explore.

What's New in v1.6.1

1. First Introduction of World Structures: Observatories & The Acropolis Citadel

• Ruined Observatories: 5 biome-tailored variants that generate naturally across the Overworld:
  • Highland: Weathered stone ruins in meadows, hills, and stony peaks.
  • Forest: Overgrown stone brick ruins entangled in oak roots and leaves.
  • Cherry: Calcite and cherry wood sanctuary with falling blossoms.
  • Floral: Birch timber ruin overgrown with azaleas and wildflowers.
  • Windswept: Storm-damaged alpine outpost with exposed rafters and wind-scoured copper.
• The Acropolis Citadel (timestop:ruined_observatory_acropolis): A massive 70×70 mountaintop sanctuary perched on Stony, Jagged, and Frozen Peaks. Features an armillary rotunda with a Diamond Pedestal altar, a sunken celestial amphitheater, an elevated sky-bridge to an observation spire, and underground crypts housing a guaranteed Golden Watch and Blank Rune.
• Balanced Spacing: Generated with 24-chunk spacing and 8-chunk separation for steady exploration (~1,200–2,000 blocks apart). Findable via /locate structure timestop:ruined_observatory_<variant>.

2. First Introduction of Clockwork Pedestals

• Stationary Time Spheres: Craftable pedestals (Copper, Golden, Diamond, Netherite, and Creative) that hold a pocket watch and project a localized temporal field when powered by redstone.
• Hands-Free Control: Keeps slow motion, fast forward, deceleration, or full time stop active in an area without needing to hold the watch.
• Visuals & Customization: Features 3D animated rotating armillary rings, tier-colored central beams, boundary ripples, and a right-click menu to adjust field radius.

3. Smooth Slow-Motion Movement & Responsive Combat

• No More Stuttering: Fixed choppy 5 FPS mob movement inside slow-motion bubbles. Client-side interpolation now runs at your full framerate (60/120/144+ FPS), so enemies glide and turn fluidly.
• Reduced Invulnerability (i-Frames): Post-hit damage immunity in slow motion is reduced from 20 ticks down to ~5 ticks, cutting the lockout window to just 2–3 ticks (100–150ms). Mobs don't get stuck in multi-second immunity walls anymore.
• Real-Time Hurt Cooldown: Hit recovery counts down on real-time server ticks instead of skipping ticks with the slowed AI. Melee combos feel immediate and responsive at normal player speed.
• Instant Projectile Hits: Arrows and bullets have zero damage lockout in slow motion.

4. Admin Rewind Toggle

• Added /timestop rewind include <true|false> (aliases: /timestop allowrewind [true|false], /timestop rewind on|off).
• Allows server owners to cleanly disable Rewind mode. When disabled, Rewind automatically disappears from watches, tooltips, and the Shift+Right-Click selection menu (which collapses from 4 rows to 3 rows). Re-enabling instantly restores it.
