Structure Effects
by Yui_
Structure Effects gives certain structures positive or negative effects and attributes that apply to players while they are inside them, adding a new difficulty layer to adventure play.
What it does
Players who enter certain structures in adventure mode receive effects and attributes, which can be either positive or negative. Once a player leaves the structure, play continues with the normal abilities. The effects change how a player moves through and plans around these areas, so entering a structure becomes a decision rather than a neutral step.
The list of structures that carry effects, along with the effects and attributes they apply, can be customized through a data pack. Effect strength and other options are set in the mod settings. Structure Effects is a Forge mod for 1.19.2 and 1.20.1, and both client and server need it. The code is not open source, and the mod is released under All rights reserved.
The latest Forge file is 1.1.0 for 1.20.1, published on 2023-12-09, and the same date marks the first release. Players and server owners can add structure effects to a world without writing code, since the choices are made in the data pack and the settings screen.
Key features
Positive and negative effects
Structures can apply attributes that either increase or decrease a player's abilities while they stand inside.
Effects end on exit
Leaving a structure returns the player to normal abilities, so the effects only last while the player remains inside.
Data pack structure list
A data pack defines which structures carry effects and which attributes each one applies.
Settings for effect values
Effect and attribute values can be adjusted through the mod settings without editing data files.

How it compares
Dynamic Difficulty is a Forge mod for 1.18.2 – 1.20.1 that shares the client and server environment, but it is not open source and is released under All rights reserved. Limited Lives is open source under the GNU Lesser General Public License v3.0 only and runs on Fabric, Forge and NeoForge for 1.18 – 1.21.5, so it covers more loaders and versions than Structure Effects.
