Script Blocks
by TheRedBrain
Script Blocks is a Fabric library that adds utility and trigger blocks for map makers and dungeon builders, including counter, delay and relay blocks.
What it does
Blocks in the mod detect nearby player-interactable blocks and fire on a configurable block position, in the same way that mob spawners, state-changing blocks, message senders, jigsaw placers and advancement givers are triggered. The utility blocks cover counting, delaying and relaying a signal, so a trigger can be chained into a sequence.
Several blocks work with jigsaw structures and are set up through a screen in the game, matching how the vanilla jigsaw blocks behave. Locations are data driven: a structure control block references a block position, and a location control block tells a teleporter which target position to send players to. Housing blocks come in two modes that decide who owns them; ownership is set by interacting with the housing block and can be revoked, and in the dimension mode a housing block placed in a player's location claims that dimension.
The mod is published for Fabric only, across 1.20.1 and 1.21.1, and it is open source under the MIT License. Client and server both need it. It requires Fabric API, Fzzy Config and Slot Customization API, and RPG Inventory is an optional addition. Instanced Dungeons requires Script Blocks.

How it compares
PanoLeap runs on Fabric for 1.21.1 – 1.21.11 with the same client and server environment, but is released under All rights reserved, so it is not open source. TreasureMap is server-side only, open source under the MIT License and published for 1.20.5 – 1.21.5. Masik's Puzzle Dungeon is a 1.20.1 Fabric mod that the server requires, with the client optional, and is open source under the GNU Lesser General Public License v3.0 only.
