Restriction
Building a custom Minecraft modpack is an art form. You want to guide players through a unique journey, but the vanilla game and even many mods offer too much freedom. The Restriction mod solves this by letting you define exactly where, when, and how players can place or interact with specific blocks. It is a powerful tool for modpack developers who want to enforce progression, create gated content, or design immersive environmental rules without writing a single line of code.
What Is the Restriction Mod?
Restriction is a lightweight utility mod designed exclusively for modpack creators. It is not meant to be used unconfigured; out of the box, it does nothing. Once you set up its JSON configuration file, however, it becomes a silent enforcer of your world’s logic. You can prevent players from placing a high-tech machine until they have enough experience, stop them from interacting with a magical altar unless they are in a specific dimension, or require a multiblock structure to be built in a closed room. The possibilities are vast and entirely data-driven.
How Restriction Works
At its core, the mod listens for block placement and right-click interactions. When a player attempts to use a restricted block, the mod checks a set of conditions you define. If the conditions are not met, the action is blocked and the player receives a customizable message. This all happens seamlessly, with no client-side installation required—Restriction is a server-side mod, so players joining your modpack don’t need to add anything extra.
Supported Minecraft Versions and Loader
Restriction is built for Minecraft 1.12.2 and runs on Forge, the most popular mod loader for that version. While 1.12.2 remains a staple for many modpacks due to its stability and extensive mod ecosystem, the mod’s design principles could easily be adapted to newer versions if demand arises. For now, if you’re developing a 1.12.2 pack, Restriction is a must-have utility.
Configuring the JSON File
On first launch, Restriction generates an example configuration file at config/restriction/restriction.json. You need to edit this file to define your own rules. The structure is straightforward: an array of entries, each specifying a block and a list of restrictions that apply to it. You can target a block by its ID and metadata, or use "ignoreMeta": true to affect all variants of that block. Each restriction has a type and optional parameters like a required experience level, a dimension ID, a minimum room size, or a list of nearby blocks that must be present.
Restriction Criteria Types
The mod offers several built-in restriction types, each with a "reverse" flag to invert the logic. Here are the main ones:
- CLOSEDROOM – Requires the block to be placed in an enclosed space. You can define which blocks count as walls and set a minimum room size.
- DIMENSION – Restricts placement or interaction to a specific dimension ID. Reverse it to ban the block from that dimension.
- NEARBYBLOCKS – Checks for a certain number of specific blocks within a radius. Perfect for requiring a multiblock structure nearby.
- EXPERIENCE – The player must have at least the specified XP level. Use reverse to require a maximum level instead.
- MINHEIGHT – Restricts based on Y-level. Reverse it to create a maximum height limit.
Each entry can combine multiple restrictions, and all must be satisfied for the block to be usable. This allows for complex, layered requirements like “must be in the Nether, below Y=30, and have at least 15 XP levels.”
How to Install Restriction for Minecraft
Since Restriction is a server-side mod, installation is simple. First, ensure you have a Forge server running Minecraft 1.12.2. Download the Restriction mod file from CurseForge or your preferred mod repository. Place the .jar file into the server’s mods folder and restart. The mod will generate a default config. Next, edit config/restriction/restriction.json to define your restrictions. If you’re using a launcher like foxygame.net, you can install Restriction directly from its add-on catalog with a single click, and the launcher will handle version compatibility and automatic updates for you. Once configured, the restrictions take effect immediately for all players on the server.
Practical Use Cases for Modpack Developers
Imagine a tech-focused pack where you want players to build a cleanroom before crafting advanced circuits. With Restriction, you can require that the assembler machine be placed only in a CLOSEDROOM made of iron blocks. Or, in a magic pack, you might restrict a powerful ritual altar to only function in a specific dimension, forcing exploration. The mod was originally created for the Exoria modpack, where it gates progression behind environmental conditions, but its generic design makes it suitable for any pack.
Another clever use is to prevent players from cheesing mechanics. For example, you can restrict a block that normally requires sky access by checking for OPEN_SKY (via reversing a closed-room check) and a minimum Y-level. The reverse flag turns MINHEIGHT into a max height check, so you can ensure the block is placed above a certain altitude. This level of control is invaluable for balancing.
Why Restriction Is a Developer’s Secret Weapon
Unlike other mods that add content, Restriction adds rules. It doesn’t bloat the pack with new items or textures; it simply gives you the power to shape player behavior. The JSON configuration is human-readable and easy to share, so you can distribute your restriction file with your modpack. Because it’s entirely server-side, players don’t need to install anything extra, reducing support headaches. And since it works with any block from any mod, you can restrict items from Thermal Expansion, Thaumcraft, or even vanilla Minecraft with equal ease.
Download Restriction and Start Experimenting
If you’re ready to take your modpack to the next level, download Restriction for Minecraft 1.12.2 and start tinkering with the example JSON. The mod is available on major mod hosting platforms, and its lightweight footprint means it won’t conflict with other mods. For those who prefer a streamlined experience, the foxygame.net launcher offers a curated catalog where you can add Restriction to your custom pack with one click, ensuring it stays updated alongside your other mods. Once you see how a few well-placed restrictions can transform gameplay, you’ll wonder how you ever built packs without it.
Conclusion
Restriction fills a niche that many modpack creators didn’t know they needed. It’s not flashy, but it’s foundational—a tool that lets you enforce your vision without compromising the sandbox spirit of Minecraft. Whether you’re building a hardcore survival experience, a guided tech tree, or a story-driven adventure, Restriction gives you the keys to lock and unlock content exactly as you intend.
