# Mobs Blocker ### Advanced Spawn Control for Your Server [](https://neoforged.net/) [](https://github.com/Dreyka-Oas/Mobs-Blocker) [](https://mcreahub.pages.dev/) [](https://opensource.org/licenses/MIT) **Mobs Blocker** has been completely re-architected to give you granular control over entity spawning. Stop mobs based on specific conditions (natural spawns, spawners, eggs) or apply rules globally across mob categories.

? How It Works & Core Features

The Logic System

Mobs Blocker intercepts every entity spawn attempt and checks rules in this specific order:

1. Specific Rules: Is there a rule for this exact Entity ID? (e.g., minecraft:zombie)
2. Preset Rules: If not, is there a rule for its Category? (e.g., monsters)
3. Global Rules: If not, is there a Global rule set?

Key Features

• Granular Control: Block mobs based on how they spawn (Natural, Spawners, Eggs, Commands).
• Smart Presets: Apply rules to entire categories (e.g., block all monsters or water_creatures).
• Global Settings: Apply a rule to every entity on the server instantly.
• In-Game Management: Full command system with auto-completion.
• Zero Lag: Uses optimized HashSet lookups and hooks into NeoForge events for minimal performance impact.
• Server-Side Only: Clients do not need to install this mod.

? The Rules System (Understanding Block Types)
When adding a rule, you define **what** to block. You can block specific sources or use "Inverse Mode" to allow *only* specific sources. | Rule Keyword | Effect | | :--- | :--- | | `all` | Blocks **ALL** spawns for this target. | | `natural` | Blocks natural spawns (darkness, biome generation). | | `spawner` | Blocks mob spawners (dungeons, trial spawners). | | `egg` | Blocks spawn eggs and dispensers. | | `command` | Blocks `/summon` or command block spawns. | | `!natural` | **Inverse**: Blocks everything *EXCEPT* natural spawns. | | `!spawner` | **Inverse**: Blocks everything *EXCEPT* spawners. | | `!command` | **Inverse**: Blocks everything *EXCEPT* commands. |

? Command Guide (Usage Examples)

All commands require OP Level 4.

1. Specific Mob Control (add)

Target a single entity type.

• Block Zombies completely:

    /spawnblocker add minecraft:zombie all

• Block Creepers from spawning naturally (but allow spawners/eggs):

    /spawnblocker add minecraft:creeper natural

• Allow Skeletons ONLY from Spawners (Inverse Mode):

    /spawnblocker add minecraft:skeleton !spawner

2. Category Presets (preset)

Apply rules to groups of mobs.
Available categories: monsters, creatures, ambient, water, misc.

• Block all Monsters from spawning naturally:

    /spawnblocker preset monsters natural

• Disable all ambient creatures (Bats, etc.):

    /spawnblocker preset ambient all

3. Global Settings (global)

Apply a fallback rule to the entire server.

• Disable Natural Spawning server-wide (Adventure mode style):

    /spawnblocker global natural

4. Management & Utilities

• Remove a rule:

    /spawnblocker remove minecraft:zombie
    /spawnblocker remove preset monsters

• List active rules:

    /spawnblocker list

• Reload Config (from disk):

    /spawnblocker reload

• Reset Everything (Wipe Config):

    /spawnblocker reset

? Configuration File (Manual Editing)
The configuration is saved automatically to `config/spawnblocker.json`. You can edit this file manually if the server is stopped. **Example `spawnblocker.json`:** ```json { "minecraft:phantom": [ "all" ], "preset:monsters": [ "natural" ], "minecraft:zombie": [ "!spawner" ], "global_settings": [ "command" ] }
