build_hyperboloid
Construct hyperboloid structures like cooling towers or hourglasses in Minecraft Bedrock by specifying base and waist radii, height, and center coordinates. Customize material, hollow/solid design, and axis orientation.
Instructions
Build HYPERBOLOID: cooling tower, hourglass, nuclear tower. Requires: centerX,centerY,centerZ,baseRadius,waistRadius,height. Optional: axis
Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| action | No | Build action to perform | build |
| axis | No | Hyperboloid axis direction: x (east-west), y (up-down), z (north-south) | y |
| baseRadius | Yes | Radius at the base in blocks. Small: 5-8, Medium: 10-15, Large: 20-30 | |
| centerX | Yes | Center X coordinate (east-west position of hyperboloid base center) | |
| centerY | Yes | Center Y coordinate (height/vertical position of hyperboloid base, typically 64-100) | |
| centerZ | Yes | Center Z coordinate (north-south position of hyperboloid base center) | |
| height | Yes | Total height of the hyperboloid in blocks. Small: 10-15, Medium: 20-30, Large: 40-60 | |
| hollow | No | Make it hollow (true) for tower shell, or solid (false) for full hyperboloid | |
| material | No | Block type to build with (e.g. stone, glass, wool, concrete, etc.) | minecraft:stone |
| waistRadius | Yes | Radius at the narrowest point (waist) in blocks. Should be smaller than baseRadius |
Implementation Reference
- The main execute method that implements the build_hyperboloid tool. Validates inputs, calculates hyperboloid positions using calculateHyperboloidPositions utility, and executes the build using executeBuildWithOptimization.
