A library for giving you more levers to use in vanilla json files.<\/p>\n
Everything here is only needed on the server, and not the client, so feel free to build your datapacks based off of this!<\/p>\n
Current Features:
\n-A new block predicate, `exclusions_lib:overlaps_structure`:
\nThis predicate will take a block position (adjusted by an optional `offset` field, like most other predicates), and optionally a `structures` and\/or `range`, and check whether it would overlap a structure. With a structures field, it only checks for certain structures, and with a value for a range (max 32), it will instead check an area *around* the position.<\/p>\n
Use this to stop features from being placed overlapping structures! Or maybe you’d want an ore that only generates near a certain structure?<\/p>\n
-Tag Exclusions (NOT IN NEOFORGE VERSION AS NEO ALREADY HAS THESE BUILT IN):
\nBasically a blacklist field for tags. Want to make a tag that contains everything in `#minecraft:small_flowers`, **except** for wither roses? But you still want it to be compatible with every other mod that would add new flowers? Just add wither roses with its “excluded” field set to true, and now you’ve made a “normal flowers” tag! Is very powerful, allowing you to do all sorts of things, like removing other mod’s edge case items from your own tags, while still keeping their item in the common tag you’re pulling from, or even straight up removing entries from other mods’ tags (or vanilla) yourself!<\/p>\n
Example Usage, for a tag that will contain everything in #minecraft:small_flowers, EXCEPT for wither roses, along with a couple other things:<\/p>\n
“`{
\n “values”: [
\n “#minecraft:small_flowers”,
\n {
\n “id”: “minecraft:wither_rose”,
\n “excluded”: true
\n },
\n “minecraft:apple”,
\n “minecraft:waxed_exposed_cut_copper_stairs”
\n ]
\n}“`<\/p>\n","protected":false},"excerpt":{"rendered":"
