SafeCrystal
by sawiq_
SafeCrystal is a Fabric client mod that blocks End Crystal placement and detonation near valuable items, using a configurable radius.
What it does
Before a player places an End Crystal on obsidian or bedrock, SafeCrystal checks the area around the target for valuable items. If any are found within the configured radius, the placement is cancelled. The same check applies when a player attacks or detonates a crystal that is already in place, so an explosion does not destroy nearby loot.
The list of valuables is picked in a two-panel screen with search. Items can be selected one by one, with Ctrl for multi-select and Shift for a range. The default scan distance is 10 blocks, and it can be changed in the config. Mod Menu is optional and opens the config screen from its list.
SafeCrystal runs on the client alone, so only the player who installs it is protected and servers need nothing. It requires Fabric API and is published only for Fabric, across 12 release versions, under the MIT License, and the project is open source.
