ShrinkRays: Resize Anything in Minecraft With Three Simple Blocks
Ever wanted to tower over a creeper like a colossus, or shrink your friend down to the size of a button? ShrinkRays makes that possible with just three clever blocks and a bit of redstone. This lightweight add-on brings the classic "ray gun" fantasy straight into your world, letting you change the size of any entity the beam touches. Whether you are building a shrinking maze for a minigame or just pranking your friends on a survival server, this mod delivers instant, hilarious results.
What ShrinkRays Adds to the Game
The core of ShrinkRays is refreshingly simple: three new blocks, each with a single job. When you power a block with redstone, it fires a beam at whatever entity it is facing and changes that entity's size. There are no complicated menus or config files to wrestle with, which is exactly why so many players keep it installed.
- Growth Ray — makes you and other entities larger.
- Shrink Ray — makes you and other entities smaller.
- Return Ray — resets any entity back to its normal size.
That is the entire toolkit, and it covers almost every scenario you can imagine. Stack a few Growth Rays in a row to create a giant boss for an arena fight, or line a corridor with Shrink Rays to build a "shrinking hallway" puzzle. Because the effect applies to entities rather than players only, you can resize cows, villagers, zombies, and even your pets. The results are frequently absurd, and that is the point.
How to Use the Ray Blocks
Using ShrinkRays is about as intuitive as Minecraft gets. Place a ray block, point it at your target, and give it a redstone signal. A lever, a button, or a pressure plate all work fine. Anything standing in the block's line of sight gets affected, so aim carefully before you flip that switch.
One detail worth remembering: the mod relies on the Pehkui library to handle entity scaling under the hood. That means Pehkui must be installed alongside ShrinkRays, or nothing will happen when you power a block. It is a one-time setup step, and most launchers will flag the missing dependency for you automatically.
Supported Versions and Loaders
ShrinkRays is built for Fabric, and it runs happily on a range of modern Minecraft releases. Players on 1.20.1 and 1.20.2 will find it working exactly as expected, and the mod has even been reported to function on 1.20.3 despite Pehkui not officially supporting that version. If you are on a slightly different build, it is always worth testing in a throwaway world first. Server owners will be glad to hear that ShrinkRays works in multiplayer too, so everyone on your SMP can join in the size-changing chaos.
If you would rather skip the manual file shuffling, the foxygame.net launcher offers a tidy one-click install for ShrinkRays, pulling in the correct Pehkui build at the same time so you never have to chase down a matching version by hand.
How to Install ShrinkRays for Minecraft
Getting started takes only a few minutes. The steps below assume you already have Fabric set up, since that is the loader this mod targets.
- Install the Fabric loader for your chosen Minecraft version.
- Download ShrinkRays for Minecraft from a trusted mod host.
- Download the matching Pehkui version as well, since it is a required dependency.
- Drop both .jar files into your mods folder.
- Launch the game and confirm the mod appears in your mod list.
If the game crashes on startup, the usual culprit is a Pehkui version mismatch. Double-check that both files are built for the same Minecraft release. Once everything lines up, you are ready to start shrinking and growing to your heart's content.
Great for Modpacks and Multiplayer
The creator is openly happy for ShrinkRays to be bundled into modpacks, which makes it an easy pick for themed packs. Combine it with chisel and bits style decoration mods and you can build detailed miniature villages, then grow yourself back to full size to admire the view. On servers, the blocks shine in PvP arenas, parkour maps, and hide-and-seek games where a tiny player can slip through gaps nobody else can reach.
Final Thoughts
ShrinkRays is a small mod with a big personality. It does not try to overhaul the game or add a hundred new items; it hands you three blocks and lets your imagination do the rest. The redstone-powered design keeps it accessible to beginners, while the entity-wide scaling gives builders and map makers plenty of room to experiment. Grab Pehkui, install the mod, and see how quickly your next build turns into a playground of giants and miniatures.
