CurveBuilding: Smooth Curves for Minecraft Builds

Mastering Curves in Minecraft with the CurveBuilding Plugin

Building straight walls and boxy houses is second nature for most Minecraft players, but when it comes to elegant arches, sweeping roads, or smooth roller coasters, the blocky world can feel limiting. That is where CurveBuilding steps in, a powerful plugin that transforms rigid selections into flowing Bezier curves. Whether you are designing a grand bridge, a winding railway, or a decorative garden path, this tool gives you the precision of WorldEdit combined with the beauty of mathematical curves.

What Exactly Is CurveBuilding?

CurveBuilding is a server plugin that works alongside WorldEdit or FastAsyncWorldEdit to place any selected structure along a Bezier curve. Instead of manually angling each block, you define control points and let the plugin calculate the smooth path. The result is a continuous, perfectly curved copy of your original selection, ideal for infrastructure projects like roads, tunnels, and aqueducts. It even supports previewing a simplified drawing of the curve before committing, so you can adjust without wasting time.

Key Features That Set It Apart

• Bezier Curve Placement: Freely position your structure along a cubic Bezier curve defined by connection and control points.
• Live Preview: See a simplified outline of the curve before building, helping you visualize the final shape.
• Continuous Curves: Chain multiple curves together seamlessly, perfect for long roads or complex track systems.
• WorldEdit Undo: Made a mistake? Standard WorldEdit undo commands work, so experimentation is risk-free.
• Directional Control: Choose whether the selection is read in the X or Z direction, and the plugin automatically orients the structure based on your facing.
• Air Replacement Mode: Use the -a flag to replace only air blocks, letting you weave a curve through existing terrain without destroying it.

Installation Guide

Getting CurveBuilding up and running is straightforward. First, ensure your server has WorldEdit or FastAsyncWorldEdit installed, as the plugin depends on one of these to handle selections. Then, download the appropriate version: for Bukkit/Spigot servers, grab the curvebuilding-bukkit-*.jar file and place it into your server's plugins directory. If you are running a Fabric client or server, you will need the dedicated Fabric version available on the plugin's official page. After copying the file, restart your server or reload plugins, and CurveBuilding will be ready to use.

For players who prefer a more integrated experience, the foxygame.net launcher provides a modern, flexible way to manage your Minecraft setup. With its built-in mod browser, you can download and install plugins like CurveBuilding directly from the menu, skipping the manual file transfers entirely. This launcher keeps everything organized and up to date, making it a convenient choice for builders who frequently experiment with new tools.

Command Reference: Shaping Your Curves

CurveBuilding introduces a set of intuitive commands that let you define, adjust, and generate curves. All commands require the appropriate permissions, which server admins can assign to trusted players.

Setting Connection and Control Points

• //bcpos set <pos type> – Sets a connection point at your current position. The pos type can be a number (1, 2, 3...) optionally followed by f (forward control point) or b (backward control point). For example, //bcpos set 1 marks the start, //bcpos set 1f sets the start's control point, and //bcpos set 2b sets the end's control point. When chaining curves, intermediate points use both f and b to maintain smoothness.
• //bcpos insert <pos type> – Inserts a new point at the specified number, shifting all later points backward.
• //bcpos shift <distance> [direction] – Moves all points by a given number of blocks. If no direction is specified, it shifts based on where you are looking.
• //bcpos remove <pos type> – Deletes a pair of connection and control points, shifting later points forward.
• //bcpos clear <pos type> – Force deletes a single point without shifting others.
• //bcpos clearall – Removes all defined points, resetting the curve setup.

Generating the Curve

• //bc [-options] [n] [m] – After selecting a structure with WorldEdit and defining all points, this command builds the curve. The optional -a flag replaces only air blocks. Use -x or -z to specify the reading direction of your selection (check your Facing on the debug screen). The numbers n and m control the density and length of the curve segments.
• /curvebuilding reload – Reloads the plugin configuration without restarting the server.

Permissions

• CurveBuilding.pos – Allows access to all bcpos commands.
• CurveBuilding.bc – Allows use of the //bc generation command.
• CurveBuilding.admin – Grants full administrative access to reload and manage the plugin.

Practical Tips for Stunning Curves

Start simple. Place two connection points with their control points to create a basic S-shaped road. Use the preview feature (by running //bc with a low n value) to see the curve outline before committing the full build. When working on large infrastructure, chain multiple curves by setting intermediate points with both forward and backward control points—this ensures the transitions are perfectly smooth. Remember that the direction you face when running the command matters; always check the debug screen (F3) to confirm whether you need the -x or -z flag. For elevated structures like bridges, build a flat template first, then use WorldEdit to move the entire curved result upward.

Why CurveBuilding Belongs in Every Builder's Toolkit

Minecraft's blocky nature often forces builders into rigid, angular designs, but CurveBuilding breaks that limitation elegantly. By combining the power of WorldEdit selections with mathematical Bezier curves, it opens up a world of organic shapes without requiring hours of painstaking manual placement. Whether you are crafting a scenic mountain road, a futuristic monorail, or a grand arched entrance, this plugin turns complex geometry into a few simple commands. The ability to preview, undo, and adjust on the fly means you can iterate quickly until the curve feels just right. For server admins, the permission system ensures that only trusted players can manipulate large areas, keeping griefing in check while empowering your creative community.

In a game where every block matters, CurveBuilding gives you the freedom to think beyond the grid. Once you master its straightforward command set, you will wonder how you ever built sweeping structures without it. So grab your WorldEdit wand, set your points, and watch your Minecraft world bend to your imagination.
