Zombies Ignore LOS
by oggvik
Zombies Ignore LOS is a Forge server mod that makes zombies pursue players even when a wall or other block stands between them.
What it does
Normally a zombie needs a clear line of sight before it locks onto a player. This mod removes that requirement, so zombies target players who are hidden behind blocks. The change also reshapes pathfinding, so zombies work out a route around obstacles toward a target they cannot see.
The mod is written in Java on Minecraft Forge and tested with Forge 36.2.42. Because it only changes zombie behavior on the server, players join without installing anything. It is a server mod and changes nothing on the client side.
Zombies Ignore LOS is published for Forge only, for Minecraft 1.16.5, and is released under the GNU General Public License v3.0 only, so its source code is open and the issue tracker is public. Its latest file is v0.1.0+mc1.16.5-Forge, first published 2026-02-14 and not updated since.
Key features
Ignores line of sight
Zombies lock onto players who are out of sight behind walls and other blocks instead of waiting for a clear view.
Changed pathfinding
The way zombies navigate around obstacles is adjusted so they can reach a target that is hidden from them.
Server-only behavior
Zombie targeting is changed on the server, so the effect applies to every player on that server without any client install.
Conflict with other zombie AI mods
It conflicts with Configurable Zombies AI and the deprecated Zombies Apocalyptic AI, and the author notes that a similar LOS feature exists in other mods.

Harder zombie encounters

Who it’s for: Server owners running Minecraft 1.16.5 with Forge who want zombie targeting to ignore line of sight. Players on such a server need nothing extra.

What the author says
A basic Minecraft Forge mod written in Java that makes it so zombies ignore line-of-sight. Meaning they can target players even if there is a wall in-between blocking their view. This does not, however, affect pathfinding or the way zombies navigate obstacles to reach their target.
