About this project
What does Ultimate Time Stop add?
Ultimate Time Stop

A temporal manipulation mod supporting both Minecraft 1.20.1 and Minecraft 1.21.1 across Forge, Fabric, and NeoForge. Freeze entities, projectile trajectories, fluids, block updates, and daylight across localized spherical bubbles or server-wide fields. Features six temporal modes, tiered pocket watches, tactical combat runes, in-game speed calibration, and version-specific firearm integration.

TACZ (Timeless and Classics Zero) Support Notice: Upstream TACZ is currently available exclusively for Minecraft 1.20.1.
- 1.20.1: Includes ballistic integration for firearms, kinetic projectiles, explosive ordnance, and Chrono Coins.
- 1.21.1: Pure vanilla projectile mechanics (arrows, tridents, fireballs, potions). Gun-specific items are excluded.
Temporal Modes
Modes can be activated using Pocket Watches or administrative commands (/timestop start <mode>):
- Time Stop: Completely freezes non-exempt entities, projectile trajectories, fluid physics, weather, and day/night cycles.
- Damage Buffer: Damage dealt to living entities accumulates during stasis and detonates simultaneously with accumulated knockback upon resumption.
- Fluid Walking: Water and lava surfaces act as solid collision blocks while stasis is active.
- Projectile Slapping: Left-click suspended arrows, tridents, fireballs, or bullets in mid-air to punch and redirect their trajectory.
- Projectile Snatching: Right-click suspended projectiles to catch them directly into your inventory without damage.
- Kinetic Stasis: Attack suspended falling blocks (anvils, sand, gravel) or primed TNT to impart velocity, launching them as high-velocity missiles when time resumes.
- Slow Motion: Modulates world simulation down to 25% speed (5 TPS default; calibratable from 0.01x to 0.99x) for fluid bullet-time evasion and precision combat.
- Matrix: World simulation drops to 25% (5 TPS), while the player receives transient speed buffs (+300% movement speed, +300% attack speed) to move and attack in real time.
- SUPERHOT: Movement-driven time dilation. The world runs at 5% speed (1 TPS) when standing still; moving, sprinting, jumping, attacking, or using items advances time in real time.
- Free Camera Aiming: Looking around with the crosshair does not progress time, allowing risk-free target acquisition.
- Entity Shaders: Features a crystal-red entity outline shader with configurable filtering (
HOSTILE,PASSIVE, orALL).
- Deceleration Field: Projects a localized temporal barrier (3.5m–6.0m radius) that applies an 80% velocity drag to incoming hostile projectiles.
- Fast Forward: Accelerates server-side simulation to 500% speed (100 TPS default; calibratable up to 50x). Speeds up mob movement, daylight cycles, crop growth, and block entities (furnaces, blast furnaces, smokers, brewing stands).
Tiered Pocket Watches
Craft and upgrade pocket watches through survival tiers. Higher tiers increase active duration, decrease recharge cooldowns, expand the localized field radius, and provide offhand/inventory bullet-dodge passives.
| Watch Tier | Registry Identifier | Duration | Cooldown | Field Radius | Passive Effect | Sockets | Unlocked Modes |
|---|---|---|---|---|---|---|---|
| Copper Watch | timestop:copper_watch |
6s (120t) | 25s (500t) | 12m | None | None | Slow Motion, Fast Forward |
| Golden Watch | timestop:chronos_watch |
10s (200t) | 18s (360t) | 24m | 3.5m Bullet Dodge | 1 | + Deceleration Field, SUPERHOT |
| Diamond Watch | timestop:diamond_watch |
14s (280t) | 12s (240t) | 42m | 4.5m Bullet Dodge | 1 | + Matrix, Time Stop |
| Netherite Watch | timestop:netherite_watch |
20s (400t) | 6s (120t) | 72m | 5.5m Bullet Dodge | 1 | All Modes (Fire-Resistant) |
| Creative Watch | timestop:creative_watch |
Infinite | None | 128m / Global | 6.0m Bullet Dodge | 1 | All Modes (Configurable Scope) |
Multiplayer Bubble Scoping: Pocket watches in survival generate localized spherical bubbles by default. Dedicated server tick rates remain at 20 TPS outside active spheres, allowing multiple players to independently control time without degrading server performance.
Temporal Runes
Socketable into Tier 2–4 pocket watches via the Watch Management GUI (Shift + Right-Click while holding a watch) to grant active and passive combat abilities:

Timeless and Classics Zero (TACZ) Integration (1.20.1 Only)
Ultimate Time Stop features native soft-dependency integration for Timeless and Classics Zero (1.1.8-hotfix+) on Minecraft 1.20.1:
- Native Ballistics in Stasis: Kinetic bullets, shotgun pellets, 40mm grenades, and RPG-7 rockets behave as physical entities in stasis. They freeze in mid-air, maintain ballistic velocity upon resumption, and interact with deflection, slapping, and orbital shields.
- Rune of the Kinetic Barrier (Neo's Palm): Hold Middle Click to freeze incoming gunfire directly in front of you. Release to let spent rounds drop, or attack to redirect the entire volley forward.
- Chrono Coins & +RICOSHOT: Equip the Marksman rune, tap C to toss a Chrono Coin (
timestop:chrono_coin), and shoot it out of the air with any firearm. Bullets ricochet toward the nearest enemy's head with amplified critical multipliers. - Dead Eye Firearm Guidance: Target marking with TACZ weapons preserves weapon audio, fire animations, and ammunition consumption while eliminating recoil spread for precision hits.
- Clean Soft-Dependency Architecture: When running in vanilla environments or on Minecraft 1.21.1, the Marksman rune, Chrono Coins, crafting recipes, charge HUD, and coin flip keybind automatically hide from all creative tabs and menus.
