About this project
What does Sleep Timelapse add?
Sleep Timelapse is designed to create a smoother and faster night experience while keeping the vanilla feel intact. It leverages the integrated tick rate command to ensure compatibility and performance across various hardware configurations. With this mod, when time speeds up, every aspect of the game—including movement, mining, and swimming—accelerates in tandem, offering a truly immersive time-lapse experience.
Customizable Settings: Adjust variables such as the acceleration curve, maximum speed, and mid-point directly in the "Sleep_Timelapse.yaml" configuration file available for both client and server.
Player-Centric Flexibility: Optionally skip the night entirely when every player is sleeping, making it ideal for servers with heavy usage or lower-end machines.
Dynamic Gameplay Acceleration: Unlike other timelapse mods, Sleep Timelapse synchronizes all gameplay elements. When the night speeds up, so do your actions—ensuring movement, mining, and swimming keep pace with the accelerated environment.
Compatibility: Sleep Timelapse works on client, LAN and Server.
