Add Custom Crystal Types with Data Packs

Understand Data Pack Structure

The FTB Ez Crystals mod supports custom crystal types through data packs. This allows you to define new crystal blocks from other mods or custom additions to work with the right-click harvest system.

Create Your Data Pack

Set up a data pack in your world's datapacks folder with the appropriate directory structure. Define your custom crystal block entries in JSON files following the mod's data pack format.

Define Crystal Properties

Specify which blocks count as budding blocks, which blocks are the harvestable clusters, and what items should drop when harvested. You can control shard output amounts and whether Fortune enchantment affects your custom crystals.

Test and Validate

Load your world and test the custom crystals. Right-click fully grown clusters to confirm they harvest correctly and reset to their first growth stage. If something doesn't work, check your JSON syntax and file paths against the mod's documentation format.
