Aps Areas
by APS
Aps Areas lets server administrators define 3D regions that run commands when a player steps inside them, and it is a server-side Fabric mod for 1.21.1.
What it does
Each region is set up from two corner coordinates in x, y and z. When a player enters the region, the server executes the commands assigned to it, up to 10 distinct commands per area, in the order they were entered. Command text can contain player x, y and z placeholders, so the output follows the position where the player stepped in.
Setup commands are locked to server operators with Permission Level 4, so regular players cannot create or change regions. The check interval, which controls how often the server tests whether players are inside a region, can be adjusted in server ticks to balance responsiveness against server load. Possible uses include portal entrances, hidden triggers, rewards tied to a region, or bespoke events in a world.
Aps Areas is server-side only, so players join without installing anything and the mod needs no client-side component. Files are published for Fabric for 1.21.1, with 1.0.1 as the latest file released on 2026-09-01. The mod is released under All rights reserved and is not open source.
Key features
Custom 3D regions
Regions are boxes defined by two corner points, so areas can cover rooms, floors or any volume in the world.
Multi-command execution
Up to 10 commands can be attached to one area and run one after another when a player enters it.
Coordinate placeholders
Commands accept player x, y and z variables, which are replaced with the entering player's current position.
Configurable check interval
The rate at which the server tests player positions against regions is set in server ticks, trading response speed for lower tick cost.
Operator-only setup
Creating and editing regions and their commands requires Permission Level 4, keeping configuration with trusted staff.

How it compares
Command on Interval is server-side only, open source under the Mozilla Public License 2.0 and published for 1.21 – 1.21.1, so it runs commands on a timer rather than on entry. Zones is open source under the MIT License and covers 1.21 – 1.21.10, extending past this mod's 1.21.1 target. Executable Commands Items runs on both client and server and is not open source, tying commands to items instead of areas.
