TimeScaleLib

TimeScaleLib is a library mod that adds advanced time scaling (bullet time) mechanics to Minecraft.

Unlike the vanilla /tick rate command, this mod only slows down non-player entities and the game world's time flow, allowing for more natural slow-motion effects while keeping player control responsive.

Features

• Independent time scaling system
• Smooth recovery transition support
• Partial Tick API for rendering compatibility
• Optional player inclusion support
• Built-in time scaling commands

Commands

Apply Time Scale

/timescale apply <scale> <duration> [<transition>|include]

Applies a time scale effect.

• scale: Time scale multiplier (0.0 ~ 1.0)
• duration: Total duration in ticks
• transition: Optional recovery transition duration at the end of the effect, occupying the final portion of duration
• include: Optional literal allowing specified players to also be affected by the slowdown

Example:

/timescale apply 0.1 120 20

Runs at 10% time speed and smoothly restores to normal speed during the final 20 ticks.

Remove Time Scale

/timescale remove

Removes all active time scale effects.

API

Currently provides:

• Apply time scale
• Query current time scale
• Remove all time scales
• Access layered partialTick values

Currently used to power bullet time effects in ParCoolSkill.
