How do I install Illusion?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on CurseForge — not every file is mirrored on our own servers.

What Minecraft version does Illusion work with?

The listing gives Minecraft 1.18.2. This is the version stated by the author or source site, not something we verified ourselves.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Illusion is a rewrite of FibLib. It allows you to lie to clients about BlockStates being sent to clients based off player predicates. Take this example...

> Prevent a player from finding Iron Ore while they are sneaking:

Illusion — Minecraft Java mod, screenshot 1

This Illusion will remap Iron Ore to Stone on clients when they are sneaking. Iron Ore will still exist on the server, but any interactions will act as if the player interacted with stone - including block-breaking speed, block drops, and more. Illusion can be used as a common-side library mod to block clients from seeing certain blocks, or as a server-side library to prevent vanilla clients from receiving certain block IDs.

Illusion is available on GitHub for download at https://github.com/Draylar/illusion and is available under the MIT license. Gradle dependencies can be found at https://maven.draylar.dev
