Usage
In the datapack for your structure modify the structure/mystruct.json:
{
"type": "hexed_structures:jigsaw", <----- this line
"biomes": "#my:tags",
"max_distance_from_center": 80,
"project_start_to_heightmap": "WORLD_SURFACE_WG",
"size": 7,
"spawn_overrides": {},
"start_height": {
"absolute": 0
},
"valid_height_range":{ <----- optional height limit (new in 1.2.0)
"min": 50,
"max": 180
},
"start_pool": "my:pool",
"step": "surface_structures",
"terrain_adaptation": "beard_thin",
"use_expansion_hack": false
}
and the structure_set/myset.json:
{
"structures": [
{
"structure": "my:structure",
"weight": 1
}
],
"placement": {
"type": "hexed_structures:center", <----- this line
"spacing": 10,
"separation": 6,
"salt": 14347342873
}
}
All other parameters work like vanilla. The base for the placement selection is the normal RandomSpread.
Note
Structures are shifted so the bounding box center is over the hexagon center.
