Zombies Apocalyptic AI

\—————–ARCHIVED—————–

Since April 13th, 2026, this mod is now considered Archived and will no longer be receiving updates or support. In its place, it has been superseded by a Kotlin rewrite named Configurable Zombie AI

Please use that mod instead for new and improved features. Also please do note that this mod and Configurable Zombie AI are NOT compatible so you can only have one or the other installed at a single time.

Zombies Apocalyptic AI

A Minecraft Forge mod that transforms zombies into a relentless, shifting horde. They ignore line-of-sight, allowing them to track victims through walls, and dynamically switch between targets to create a more chaotic and overwhelming experience.

This mod affects target selection and awareness, but does not modify pathfinding or navigation logic.

Compatible Versions

• Minecraft: 1.16.5
• Mod Launcher: Forge (tested on 36.2.42)
• NOT compatible with the Zombies Ignore LOS mod which this mod is a superset of.

Features

• Apocalyptic Vision: Zombies ignore line-of-sight and can target players, villagers, and iron golems through walls.
• Dynamic Target Switching: Zombies don’t just stick to one target. They periodically re-evaluate their surroundings and may switch to a more “attractive” target.
• Weighted Random Selection: Target selection is not strictly based on the closest entity. Zombies have a “wandering eye” based on distance and health, making their behavior less predictable.
• Commitment Categories: When a zombie picks a target, it is assigned a commitment duration (Short, Medium, Long, or Forever). This ensures they don’t “thrash” between targets too rapidly while still allowing for sudden shifts in focus.
• Unified Targeting: Applies to Players, Villagers, and Iron Golems.
• Runtime Configuration: Most settings can be adjusted on-the-fly via commands and are saved per-world.

Commands

• /zombies_ai enable: Enables the apocalyptic AI.
• /zombies_ai disable: Disables the apocalyptic AI.
• /zombies_ai status: Shows current configuration and status.
• /zombies_ai range <distance>: Sets the follow range (distance at which zombies spot victims). (Default: 50.0)
• /zombies_ai persistent <true|false>: Prevents zombies from despawning naturally.
• /zombies_ai target weights <distance> <health>: Sets the weights for target selection scoring. (Default Distance: 1.0, Health: 0.0)
• /zombies_ai target switching <interval> <commitTime> <queryRange>:
• interval: How often (in ticks) to re-evaluate targets. (Default: 20)
• commitTime: Base commitment duration in seconds. (Default: 10)
• queryRange: Search radius for potential new targets. (Default: 30.0)
• /zombies_ai kill: Kills all zombies in the world.

Note: You need level 2 permissions (OP) to use these commands.
