Advanced Hostility
Tired of predictable mob behavior? Advanced Hostility is a powerful configuration tool that gives you total control over the world's ecosystem. Whether you are a server administrator creating a unique PvE experience, a modpack creator weaving intricate mob interactions, or a solo player looking for a fresh challenge, this mod provides the tools you need.
Core Features
-
Custom Factions: Group any mob from vanilla or other mods into factions like "The Undead Legion" or "Forest Guardians".
-
Complex Relationships: Set factions to be Friendly, Hostile, or Neutral towards each other. Create global alliances or spark world-ending wars between creatures.
-
AI Overhaul: Grant passive mobs like sheep and villagers aggressive AI with custom damage and speed. Or, make Creepers ignore players entirely!
-
High Compatibility: Designed to intelligently supplement, not just replace, vanilla AI. This allows for dynamic and emergent interactions with mobs from other mods.
-
Server-Friendly Management: All configurations can be edited in-game via commands and reloaded without a server restart, making it perfect for server administrators and modpack creators.
Configuration Guide
Advanced Hostility is configured through the [advancedhostility-common.toml] file (for global settings) and the [advancedhostility-server.toml] file (for world-specific overrides).
The configuration is broken down into four main rule types, which are processed in the following order of priority: Mob Rules > Faction Rules > Vanilla Behavior.
1. Sets
Sets are reusable groups of entities. They are a convenient way to manage large numbers of mobs.
Format: set_id;member1,member2,@another_set,!exclude_mob
@references another set.!excludes an entity or set.modid:*includes all mobs from a specific mod.
Example:
toml sets = [ "undead;minecraft:zombie,minecraft:skeleton,minecraft:zombie_villager", "monsters;minecraft:*,!minecraft:creeper,!@undead" ]
2. Factions
Factions are groups of entities that share common relationships.
Format: faction_id;member_list;relationship1;relationship2
member_list can contain entity IDs or set references (e.g., @undead).
Example:
toml factions = [ "illagers;minecraft:pillager,minecraft:vindicator;hostile=players,villagers", "players;player;friendly=wolf_pack" ]
3. Mob Rules
Mob Rules define specific behaviors for individual entity types, overriding any faction rules.
Format: mob_id;rule1;rule2
proactive=<target>: Makes the mob actively hunt the target.ignore=<target>: Makes the mob ignore the target.
Example:
toml mob_rules = [ "minecraft:creeper;ignore=player", "minecraft:wolf;proactive=@undead" ]
4. Aggression Rules
This powerful feature gives non-hostile mobs a complete combat AI overhaul.
Format: mob_id;damage=<value>;speed=<multiplier>
damage: The final damage dealt (1.0 = half a heart).- [speed]: A multiplier for movement speed when chasing a target.
Example:
toml aggression_rules = [ "minecraft:sheep;damage=8.0;speed=1.8", "minecraft:villager;damage=10.0" ]
