Echostruct
A data pack with a bit of added structure, enriching the adventure experience.
Quick answer
Which Echostruct release should I use?
echostruct-0.3.jar targets 1.20.1 with Forge. The project page does not say whether this file belongs on the client, dedicated server, or both. All 3 required mods have matching files.
Where it goes
Is Echostruct required on the client, server, or both?
The project page does not say whether this file belongs on the client, dedicated server, or both.
The source does not explicitly classify this release as client-only or server-only.
What else does echostruct-0.3.jar need?
echostruct-0.3.jar. Change the file and its required mods may change too.
Install Supplementaries, Integrated API, Moonlight Lib first. We found matching files for this game-version and loader setup. 20 come through another mod in the chain.
20 extra mods were pulled in by other dependencies. Indented rows show who needs each one. We only count dependency files that match this setup. A file for another loader does not fill the gap.

About this project
What does Echostruct add?
description
Needed: Integrated api
A data pack with a touch of structure that enhances the adventure experience. This data pack is designed to enrich the world and offer alternative solutions for those frustrating searches. In fact, it’s a project with unlimited potential since it relies on an integrated API, providing high flexibility for mod dependencies.
Linkage
What has been achieved so far:
•mowziesmobs
•fromtheshadows
In the plan:
•jerotes village
•opposite force
•wyrmroot
•and more.......
I strongly recommend loading the initial version together with mowziesmobs and fromtheshadows; with only vanilla, this datapack has just one structure!
