        }
    }
    // We also need to scan all loot predicate in the upcoming/"current" manager, given even though vanilla doesn't add
    // any predicates by default that have to do with shears, we want to make sure we catch any that may be defined by
    // a mod or data pack

Example 2 with LootEntry

use of net.minecraft.loot.LootEntry in project Mekanism by mekanism.

the class LootTableModifierReloadListener method modifyEntry.

private static boolean modifyEntry(LootEntry entry, ITag<Item> shearsTag) {
    boolean modified = false;
    if (entry instanceof ParentedLootEntry) {
        // If the entry is a parented loot entry, check if any of the child entries need their conditions modified

            modified |= modifyEntry(child, shearsTag);

    modified |= modifyConditions(LOOT_ENTRY_CONDITIONS.getValue(entry), shearsTag);
    // in a different way but there isn't much that can be done about that
