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.

Commands

Apply Time Scale

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

Applies a time scale effect to the game world.

• scale: Time scale multiplier (0.0 ~ 1.0)
• duration: Optional total duration in ticks. Default is -1; when set to -1, the time scale effect lasts indefinitely
• transition: Optional recovery transition duration in ticks. Default is 20; when set to -1, the transition is applied throughout the entire duration of the time scale effect
• target: Optional entity whose physical movement will also be affected by time scaling (typically the player). Default is null

Example:

/timescale apply 0.1 120 20

Runs at 10% time speed for 120 ticks and smoothly restores 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 provide bullet time effects for ParCoolSkill.
