YepBlocked

YepBlocked gives you complete control over entity spawns — any mob from any mod, controlled via simple in-game commands with tab completion. No manual config editing needed (but it’s there if you want it).

Features

• Global toggles — block or allow all natural / spawner / trial spawner / egg spawns at once
• Per-entity overrides — fine-tune specific mobs (e.g. block phantom natural spawns but allow spawn eggs)
• Glob & regex patterns — use minecraft:* or .*golem to match entire groups at once
• Hot-reload — apply config changes instantly with /yb reload, no restart required
• Persistence — config auto-saves to config/YepBlocked.json on first run

Commands

All commands require operator privileges (permission level 2):

| Command | Description |
|—|—|
| /yb reload | Reload config from disk. Only needed after manual edits — changes via /yb add, /yb remove, /yb global apply immediately |
| /yb global [flags] | Set global spawn defaults for all entities. Run without flags to see current settings |
| /yb add <entity> [flags] | Add an override for a specific entity |
| /yb remove <entity> | Remove a specific entity override |

Example: /yb global natural — disable natural spawns for all entities at once.

Example: /yb global ~natural — re-enable natural spawns globally.

Example: /yb global natural egg — disable natural spawns AND spawn eggs for all entities.

Example: /yb add minecraft:creeper natural=false egg=true — block natural creeper spawns but allow eggs.

How flags work

Each override (global or per-entity) can control four spawn sources independently:

• natural — natural world spawns (day/night cycle, biomes)
• spawner — monster spawners
• trial — trial spawners
• egg — spawn eggs

Flag syntax:

• Bare flag = block: /yb add zombie natural
• ~ prefix = allow: /yb add zombie ~natural
• = syntax: /yb add zombie natural=false egg=true
