Collective Mod (1.21.11, 1.20.6) – Modding Framework

Collective is a shared library mod that provides common code and utilities for all of Serilum's mods, supporting Fabric, Forge, NeoForge, and Quilt mod loaders across Minecraft versions from 1.20.1 through 26.1.

Anyone who has browsed Minecraft mod libraries has likely encountered a frustrating scenario: you download a promising quality-of-life mod, launch the game, and immediately hit a crash screen telling you a dependency is missing. Collective exists to solve exactly that problem for the entire Serilum mod ecosystem. With over 44 million downloads on Modrinth alone, Collective has quietly become one of the most widely installed library mods in the Minecraft modding community. It centralizes shared code so that Serilum — one of the most prolific Minecraft mod authors — can maintain, update, and improve dozens of mods efficiently without duplicating logic across every single project.

Key Features of Collective

• Centralized Configuration Management — Collective handles all config files and in-game settings menus for every dependent Serilum mod. Instead of each mod implementing its own config system, Collective provides a unified framework. This means you get a consistent settings experience across all Serilum mods, and config files are organized in a predictable, clean structure.
• Cross-Mod Compatibility Variables — The library includes shared variables specifically designed to increase compatibility between Serilum's projects and other third-party mods. This reduces the chance of conflicts when you run multiple mods together, which is a common pain point in heavily modded Minecraft instances.
• Shared Utility Functions — Collective bundles a large collection of reusable functions that prevent code duplication across Serilum's mod lineup. For players, this translates to smaller total file sizes when running multiple Serilum mods, since common logic lives in one place rather than being copied into every jar file.
• Entity Replacement and Resupply Events — The library provides a dedicated event system for replacing and resupplying entities in-game. This is the backbone that powers several of Serilum's gameplay mods, enabling features like mob modifications and item respawning to work reliably without conflicting with vanilla mechanics.
• Mod Toggle Functionality — Collective allows you to toggle the functionality of bundled mods on and off without removing them from your mods folder. This is especially useful if you want to temporarily disable a specific Serilum mod for testing or troubleshooting without disrupting your entire mod setup.
• Access Transformers and Wideners — The library contains the necessary access transformers and wideners that allow Serilum's mods to interact with private Minecraft fields. This technical infrastructure is what makes many of the deeper gameplay modifications possible across all supported mod loaders.
• Cross-Loader Networking Code — Collective includes networking utilities for sending packets via the Common source set, enabling Serilum's mods to work in multiplayer environments consistently across Fabric, Forge, NeoForge, and Quilt without loader-specific networking implementations.

How to Install Collective

1. First, make sure you have a compatible mod loader installed. You can use Fabric, Minecraft Forge, NeoForge, or Quilt — Collective supports all four.
2. Download the correct version of Collective for your Minecraft version and mod loader from the download section below.
3. Place the downloaded .jar file into your .minecraft/mods folder. If the folder does not exist, create it manually.
4. Launch Minecraft using your mod loader profile. Collective will load automatically and make itself available to any dependent Serilum mods.
5. Install any Serilum mods you want to use — they will detect Collective and function normally. No additional configuration of Collective itself is required.

Requirements & Compatibility

What's New

• Version 26.1 updated all mixin files to target their correct classes, improving stability and reducing potential conflicts with other mods.
• Continued multi-loader support across Fabric, Forge, NeoForge, and Quilt for the latest Minecraft versions.
• Ongoing maintenance and compatibility updates to support Serilum's full mod catalog.
• The complete changelog with all previous versions is available on Serilum's official site.

Pros and Cons

Alternatives to Collective

• Fabric API — The core library mod for Fabric-based mods, providing essential hooks and APIs that most Fabric mods depend on. Serves a similar role as a shared dependency but for the broader Fabric ecosystem rather than a single author's mods.
• Architectury API — A cross-platform library that helps mod developers write code once and deploy across Fabric, Forge, and NeoForge. Useful if you are looking for cross-loader compatibility in a broader context.
• Cloth Config API — A popular configuration screen library used by many Minecraft mods. If you appreciate Collective's unified config management, Cloth Config provides similar functionality for non-Serilum mods.

Frequently Asked Questions

Do I need Collective to use Serilum's mods?

Yes — Collective is a mandatory dependency for all of Serilum's Minecraft mods. Without it installed, any Serilum mod will fail to load and your game will either crash or display an error on startup. Simply download the matching version of Collective and place it in your mods folder alongside the Serilum mod you want to use.

Does Collective add any visible features or changes to gameplay?

No — Collective is purely a background library mod and adds no visible features, items, blocks, or gameplay changes on its own. It only provides shared code and utilities that other Serilum mods rely on. You will not notice any difference in your game from installing Collective alone.

Is Collective compatible with Fabric, Forge, NeoForge, and Quilt at the same time?

Yes — Collective supports all four major mod loaders. However, you need to download the correct version for your specific mod loader. Each loader has its own Collective jar file, so make sure the version you download matches both your Minecraft version and your mod loader.

Will Collective cause performance issues or slow down my game?

No, Collective appears to be lightweight and should not cause noticeable performance impact. It only loads shared code into memory that dependent mods would otherwise include individually. In fact, by centralizing common functions, it can reduce overall memory usage compared to each mod bundling its own copy of the same utilities.

What happens if I have the wrong version of Collective installed?

A version mismatch will typically cause dependent Serilum mods to fail to load or crash the game during startup. Always ensure your Collective version matches the Minecraft version and mod loader version you are running. When updating Minecraft or your mod loader, update Collective at the same time to avoid compatibility issues.
