Gravity Anchors: Master Local Gravity in Minecraft
Imagine turning any block into a miniature black hole, a repulsion field, or a trampoline that flings mobs and items across your world. The Gravity Anchors add-on makes this a reality, giving server admins and players a physics-bending tool that works seamlessly with vanilla mechanics. Whether you want to build automated item collection systems, design devious traps, or simply have fun with gravity, this plugin delivers a polished, lag-free experience.
What Are Gravity Anchors?
Gravity Anchors are special blocks that warp local gravity. Once placed or marked, an anchor continuously affects all nearby entities—items, mobs, and even players—based on its current mode. The plugin is built for performance, capping velocities and limiting entity scans to keep your server running smoothly even with dozens of active anchors. It works on Paper, Spigot, Bukkit, and Purpur servers running Minecraft 1.21.1 through 1.21.11, as well as the 26.1.x server line, and requires Java 21.
How Gravity Anchors Work
Every few ticks, each anchor scans a configurable radius and applies a velocity change to entities inside. The effect is smooth and capped, so nothing gets accelerated to game-breaking speeds. You can cycle through three distinct modes by right-clicking the anchor block:
- Attract: Pulls entities toward the anchor. Perfect for funneling items into hoppers or gathering mobs into a kill chamber.
- Repel: Pushes entities away. Use it to create safe zones, mob-proof perimeters, or knockback traps.
- Launch: Fires entities upward and outward on a timer. Build player launchers, item cannons, or surprise traps that send intruders skyward.
The anchor block itself glows with a subtle particle effect, and the action bar displays the current mode whenever you interact with it. Anchors persist across server restarts, so your contraptions stay intact.
Creating and Using Gravity Anchors
There are two ways to set up a Gravity Anchor. The simplest is to look at any existing block and run the command /gravityanchor. That block instantly becomes an anchor in Attract mode. Alternatively, you can obtain a dedicated Gravity Anchor item by typing /gravityanchor item. This gives you a glowing lodestone that you can place like any other block—breaking it returns the item, making it easy to reposition.
Once placed, right-click the anchor to cycle through Attract, Repel, and Launch modes. A sound cue and action bar message confirm the switch. You can fine-tune each anchor individually with the /gravityanchor tune command, adjusting radius and strength on the fly. The plugin also respects sneaking players by default, so you can walk through a field without being affected if you hold shift.
Commands and Permissions
All commands start with /gravityanchor (aliases: /ga, /gravity, /anchor). Here’s a quick reference:
/gravityanchor– Mark the block you’re looking at as an anchor./gravityanchor mode <attract|repel|launch>– Set the mode of the looked-at anchor./gravityanchor tune <radius|strength> <value>– Adjust radius (max 32) or strength (max 5) for the looked-at anchor./gravityanchor item– Receive a placeable Gravity Anchor item./gravityanchor list– Show all registered anchors with distance./gravityanchor remove– Delete the anchor you’re looking at./gravityanchor clear– Remove every anchor in the world (admin only)./gravityanchor reload– Reload the configuration file (admin only)./gravityanchor info– Display plugin version and current settings.
Permissions are split into two nodes. gravity.use allows players to create, tune, cycle, list, and remove anchors, as well as get the item. gravity.admin grants access to the clear and reload commands, and includes gravity.use. By default, only operators have these permissions, but you can assign them to any group with your permission manager.
Configuration and Tuning
The config.yml file gives you full control over how Gravity Anchors behave. You can disable player movement entirely, exempt sneaking players, set a hard velocity cap, and define the default radius and strength for each mode. The task period determines how often the field engine runs—lower values make the effect smoother but use more CPU. The max-entities-per-anchor option prevents a single anchor from overwhelming the server when too many entities crowd around. Launch mode has its own interval setting, so you can make launch pads fire rapidly or slowly.
If you’re managing a server through a platform like foxygame.net, you’ll appreciate how easy it is to keep Gravity Anchors up to date. The foxygame.net launcher includes an add-on catalog where you can find Gravity Anchors and install it with a single click, automatically matching the correct version for your server’s Minecraft release.
Compatibility and Installation
Gravity Anchors is built against the Spigot API without using Paper-only classes, ensuring broad compatibility across Paper, Spigot, Bukkit, and Purpur. It has been verified on Minecraft 1.21.1 through 1.21.11 and the 26.1.x server line (specifically 26.1.2) with Java 21. To install, simply download Gravity Anchors and place the JAR file into your server’s plugins folder, then restart or run /reload. No additional dependencies are required.
Once installed, you can start experimenting immediately. Mark a block near your storage system to attract items, set up a repel field around your base to keep creepers at bay, or build a launch pad that sends players soaring to a floating island. The plugin’s rate-limiting and velocity clamping ensure that even on busy servers, the experience stays fluid and fair.
Gravity Anchors opens up a new dimension of creativity without adding complex redstone or command block logic. It’s intuitive, lightweight, and deeply configurable—perfect for survival, minigames, or just messing around with friends.
