About this project
What does SubTick add?
SubTick
This mod uses Fallen's fabric mod template.
A carpet extension that allows you to freeze and step to any specific tick phase, as well as step through tile ticks, fluid ticks, block events, entities, and block entities individually. Get it on your client for highlights and a HUD.
Commands
