Ghostblocks
by Rubyboat1207
Ghostblocks is a client-side configuration mod for Fabric that adds visual effects and a set of tweaks, many of them playful and some practical.
What it does
Most of the content is client-side: the features, options and visual effects change only what a player sees and how their own character moves. Each feature is turned off by default, so a player who never opens the settings will not notice the mod at all. Settings are managed through Cloth Config API, and the mod also needs Fabric API to run.
A ghost block button, bound to the G key by default, places a ghost block under the player. A server-side option lets the server replace non-air blocks with ghost blocks to stop flying exploits, and it is off unless the server owner enables it. Other tweaks include a frozen mode that makes blocks slippery like ice, a bouncy mode that turns a block into slime, and changes to the F3 debug screen that remove the negative numbers. Players need the mod, while servers may add it for the opt-in feature and can run without it. The project is open source under the MIT License, with a public source repository.

Optional server feature
A server-side option replaces non-air blocks with ghost blocks to stop flying exploits, and only servers that enable it use it.

What the author says
Ghostblock (or ghost for short) is a mod me and my friend mlgnez have been working on for over a year! It contains many client-sided tweaks that are either fun, or frustrating depending on how you look at it. Some might even be useful! However you see it, all* features are disabled by default so you wont notice it in…
