What is GTNH Customizer?
GTNH Customizer is a companion mod designed specifically for the GregTech: New Horizons (GTNH) modpack, offering a suite of quality-of-life tweaks and powerful new commands that give players unprecedented control over their world. Whether you are tired of hostile mobs interrupting your building sessions, need a reliable way to teleport across dimensions, or want to fine-tune your Xaero’s Minimap integration, this mod delivers a polished set of customizations that feel like they should have been part of the pack from day one.
Player-Specific Mob Targeting
One of the most innovative features is the ability to disable hostile mob targeting on a per-player basis. Using either a player’s UUID or their in-game name, you can make creepers, zombies, and other threats completely ignore a specific player. This is perfect for server administrators who want to grant peaceful building time to certain members without switching the entire world to Peaceful mode, or for players who need a break from constant combat while working on complex machinery.
Cross-Dimensional Teleportation
Navigating the sprawling dimensions of GTNH can be tedious, but the mod introduces a dedicated cross-dimensional teleport command. The teleport-cross-dimension command (also aliased as tpxd or tpd) allows you to jump between dimensions while specifying coordinates relative to the destination world. You can even use player-relative coordinates, such as ~10 ~ ~10, to appear ten blocks away from your current position in the target dimension. This makes moving between your Overworld base, the Nether, and other custom dimensions effortless.
Enhanced Xaero’s Minimap Teleportation
If you rely on Xaero’s Minimap or World Map for navigation, the mod patches the teleport command format to be far more flexible. Instead of simply appending coordinates to a fixed command, you can now use dynamic placeholders. This means your waypoints can trigger commands that adapt to your current context. The available substitutions include:
- {n/name} – Your player name
- {dimension/dim/d} – The numeric dimension ID of the waypoint
- {x} – The waypoint’s X coordinate
- {y} – The waypoint’s Y coordinate
- {z} – The waypoint’s Z coordinate
- {rotation/rot/r/yaw} – The waypoint’s rotation or yaw value, if set
This level of customization ensures that your teleport commands work exactly as you intend, no matter which dimension or location you are targeting. For those who prefer a streamlined modding experience, the foxygame.net launcher offers a convenient way to install GTNH Customizer directly from its built-in mod menu, making it easy to keep your modpack up to date without manual file management.
Dimension Listing and Management
Keeping track of dimension IDs can be a headache, especially in a pack like GTNH with numerous custom dimensions. The mod adds a simple list-dimensions command that displays all available dimensions along with their numeric IDs. You can even filter the results by name or limit the output to a specific number of entries, making it easy to find exactly the dimension you need for your next teleport.
Utility Commands for Everyday Tasks
Extinguish Fire
Accidental fires can destroy hours of work in seconds. The extinguish command lets you instantly put out fire in a defined radius or cubic area, using either player-relative or absolute coordinates. Whether you need to save a wooden structure or clear a burning forest, this command is a lifesaver.
Repair Items
Durability management is a constant concern in GTNH. The repair command offers a comprehensive solution, allowing you to repair items in your entire inventory or target specific slots. Sub-commands let you repair only the item in your hand, off-hand, armor slots, hotbar, or main inventory. This granular control means you can quickly fix your most-used tools without wasting resources on items you rarely touch.
Bone Meal for Special Saplings
Growing Tinker’s Construct Slime Saplings, Thaumcraft Greatwood Saplings, and Silverwood Saplings often requires patience. GTNH Customizer adds the ability to use bone meal on these saplings, speeding up their growth significantly. This small tweak removes a lot of waiting time and helps you get your resource farms up and running faster.
Improved NBT Editing
Server Utilities’ /nbtedit command receives several smart upgrades. If your ray cast doesn’t hit a valid block or tile entity, the command now automatically targets the item in your hand (as of version 0.11.0+, this also applies when the hit block lacks a tile entity). You can submit or cancel your edits using customizable key bindings, delete unwanted NBT tags with a dedicated key, and even add new NBT items to empty lists. When a list already contains items, the mod intelligently restricts additions to the same NBT type, preventing data corruption.
Enderman Teleport Prevention
Few things are more frustrating than an Enderman teleporting away mid-fight or disturbing your builds. GTNH Customizer lets you completely disable teleportation for Endermen and similar mobs, keeping them grounded and manageable.
Status Effect Curing
The /cure command is a versatile tool for removing unwanted status effects. By default, it clears negative effects, but you can configure it to also remove positive, vanilla, or modded effects. This gives you precise control over your character’s condition, whether you want to shake off a nasty poison or reset an unintended buff.
Quality-of-Life Tweaks
Beyond the major features, GTNH Customizer includes several smaller but impactful improvements. Numpad inputs are now fully supported in all ServerUtilities text boxes, making numerical entry much smoother. Additionally, when using Xaero’s World Map, hovering over the map will display the biome name at the cursor position, provided the area is within your render distance. This makes exploration and base planning far more intuitive.
Conclusion
GTNH Customizer is a thoughtfully crafted mod that fills in the gaps left by the base GregTech: New Horizons experience. From per-player mob targeting and cross-dimensional teleportation to enhanced map integration and inventory repair, every feature is designed to reduce friction and give players more control. The mod’s attention to detail, such as the flexible teleport command placeholders and the smart NBT editing improvements, shows a deep understanding of the pack’s needs. Whether you are a server admin looking to offer a smoother experience or a solo player tired of repetitive tasks, GTNH Customizer is an essential addition that makes the already deep GTNH journey even more enjoyable.
