Adding Crystal Apothecary Harvestables - DaFuqs/Spectrum GitHub Wiki

The Crystal Apothecary is a functional block that automatically harvests blocks in it's vicinity. Making blocks harvestable is as simple as adding them to the spectrum:crystal_apothecary_harvestable block tag. There is another functionality to the Crystal Apothecary, though: It can simulate block growth in unloaded chunks (mainly intended, but not limited to for gemstone cluster type blocks). Whenever a Crystal Apothecary get's loaded it checks how long it was unloaded, checks it's surroundings and tries to estimate, for example, how much Amethyst would have been grown in a geode, based on the amount of budding blocks & blocks next to them that match certain criteria (where Amethyst Clusters could grow).

You can specify additional simulations, or edit existing ones, by placing json files in the directory <data_pack_or_mod_name>/crystal_apothecary_simulations/.

Properties:

• (Identifier) budding_block: The id of a block that should be searched around of
• (Identifier[]) valid_neighbor_blocks: List of blocks that should be counted next to each budding_block
• (int) ticks_for_compensation_loot_per_valid_neighbor: The amount of ticks per found valid block it takes to generate compensation loot. Adjusted to match the randomTickSpeed gamerule. Vanilla amethyst roughly grows a finished Cluster every ~10.000 ticks with default randomTickSpeed of 3
• {} compensated_loot:
  • (Identifier) item: The item to give
  • (int) count: The number of items to give
  • (String) nbt: An nbt string for the result

Growth Estimates (ticks_for_compensation_loot_per_valid_neighbor)

For Vanilla's amethyst:

• There are /gamerule randomTickSpeed random ticks in each 161616 cube per game tick (default: 3)
• When a budding block it ticked, there is a 20% chance to choose a random direction and check if a bud can grow/advance at that pos
• Vanilla's and Spectrum's Buds all have 4 growth stages to get fully grown

This results in

• (random_tick_speed / (16*16*16)) * empty_blocks_next_to_budding_blocks * grow_chance * (1 / growth_stage_count) average grown clusters per tick.
• => ~5.000 ticks per budding block, with all faces exposed
