Example: `minecraft:zombie`. - **`blocked_biomes`**: Biome ids excluded from newly generated chunks. Replacements are selected by climate and preserve the land/water category. Example: `minecraft:plains`. - **`biome_exceptions`**: Biomes that cannot be selected as replacements. `minecraft:mushroom_fields` is excluded by default because it has special terrain requirements. - **`blocked_structures`**: Structure ids prevented from starting in newly generated chunks. Example: `minecraft:village_plains`. - **`blocked_dimensions`**: Vanilla or modded dimension ids that entities cannot enter. Travel is cancelled before changing level. Example: `minecraft:the_end`. - **`blocked_items`**: Vanilla or modded item ids removed from loot, item entities, player inventories, crafting and furnace results, open menus, and supported storages. Example: `minecraft:elytra`. - **`storage_scan`**: Group of settings for periodic removal of blocked items from loaded block-entity inventories. - **`storage_scan.enabled`**: Enables or disables periodic storage scanning. Event-based item and loot blocking continues to work when this is `false`. - **`storage_scan.interval_ticks`**: Delay between complete storage scan cycles. The default is `300` ticks, approximately 15 seconds. - **`storage_scan.block_entities_per_tick`**: Maximum number of queued block entities checked per tick. The default limit is `512`. - **`storage_scan.skipped_namespaces`**: Mod namespaces whose physical storages must not be scanned. Example: `["examplemod"]`. The mod also creates `.minecraft/config/DisablerGuide.md` with the same parameter explanations. Unopened loot-table containers are left untouched until their loot is generated, preventing interference with Lootr conversion. If an old `.minecraft/config/disabler-server.toml` exists and JSON does not, known settings are migrated automatically. The TOML file is retained as a backup, while all further configuration uses JSON. Watch on [GitHub](https://github.com/waterflane/Disabler) how it works!
