Adding Crystal Apothecary Harvestables

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:

• budding_block (Block ID): The id of a block that should be searched around of
• valid_neighbor_blocks (List of Block IDs): List of blocks that should be counted next to each budding_block
• ticks_for_compensation_loot_per_valid_neighbor (int): The amount of ticks per found valid block it takes to generate compensation loot. Adjusted to match the randomTickTime-gamerule. Vanilla Amethyst roughly grows a finished Cluster every ~10.000 ticks with default randomTickTime of 3
• compensated_loot (Item ID + count + nbt): The item to give

Growth Estimates (ticks_for_compensation_loot_per_valid_neighbor)

For Vanillas Amethyst:

• There are /gamerule randomTickTime 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

• (<randomTickSpeed> / 16*16*16) * empty_blocks_next_to_budding_blocks * grow_chance * (1 / growth_stage_count) average grown clusters per tick.
• => ~10.000 ticks per budding block
