World Mob Vision
by Itamio
World Mob Vision changes how far hostile mobs can see and chase players, with a per-type detection range set in a config file.
What it does
Any hostile mob standing inside the configured detection range, including zombies, skeletons, spiders and creepers, will pursue and strike whichever player is closest. Players who have felt ignored by hostile mobs in their world can raise that range so mobs find them from further away. Setting a mob's range to 0 stops that mob from targeting players at all.
The ranges are read from a file named mobvision.txt, so each mob type can be tuned separately. Changes are picked up roughly every second, so an edited file takes effect while the world is running and the game does not need a restart. New items, blocks and commands are added by the mod alongside the mob behavior.
World Mob Vision is published for Forge only, with a single build, 1.0.0, for 1.12.2. It runs on the server side only, so players join without installing anything. The code is under All rights reserved, and the mod is not open source.
Key features
Per-mob detection range
Each hostile mob type has its own sight range, so a single zombie setting does not have to match skeletons or creepers.
Targeting off switch
Setting a mob's range to 0 removes its ability to target players, which is useful for mobs a server owner wants passive.
Live config changes
The file is re-read once per second, so new ranges take effect while the game keeps running.
Additional items and commands
The mod adds new items, blocks and commands that build on the targeting system.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Making hostile mobs more aggressive
A server owner can raise detection ranges so hostile mobs find players from further away in a survival world.
Disabling targeting for specific mobs
Setting a range of 0 for a chosen mob type stops it from attacking players while other mobs keep their behavior.
Who it’s for: Server owners who want to tune hostile mob aggression on a Forge 1.12.2 world, without installing anything on player clients.
