hbmspace:tilted_spire
Tilted rock spires.
A chunk starts a spire with probability 1/c^2, where c is chance_high where noise exceeds the threshold and chance_low elsewhere. The spire is a cone of rock with radius at Y mid, narrowing upward and leaning by the tilt, built down onto existing ground; each column's top block is regolith. Base structures avoid it.
Fields
| Field | Meaning and default | Range |
|---|---|---|
biomes | Vanilla structure biomes. | |
spawn_overrides | Vanilla spawn overrides. | |
step | Vanilla generation step. | |
terrain_adaptationOptional | Vanilla terrain adaptation; default none. | |
noise | Noise ID; inline noise raises an error. | |
threshold | Noise level selecting chance_high, compared as 2t - 1. | \texttt{f32} |
chance_high | Start chance divisor above the threshold. | [1, 1024] |
chance_low | Start chance divisor at or below the threshold. | [1, 1024] |
min_size | Smallest radius. | [1, 64] |
max_size | Largest radius; must exceed min_size. | [2, 64] |
min_point | Lowest point factor. | \texttt{f32} |
max_point | Highest point factor. | \texttt{f32} |
min_tilt | Smallest tilt. | \texttt{f32} |
max_tilt | Largest tilt. | \texttt{f32} |
curve | Leans quadratically instead of linearly. | |
mid | Y of the full radius. | \texttt{i32} |
rock | Spire block. | |
regolith | Top block of each column. |
