VoxelWorld

A chunk-streamed voxel world returned by datumhue.voxel.world. Move center to stream chunks in and out; chunk content arrives through the on_chunk_load callback.

Obtained from
datumhue.voxel.world

The examples on this page start from:

lua
local scene = datumhue.scene.new({ width = 320, height = 240 })
scene:mount({ width = 320, height = 240 })
local world = datumhue.voxel.world(scene, { chunk_size = 16 })

Fields 4

FieldTypeAccessDescription
centerVec3read/writeStreaming focus in the world's local space; assign to move it (e.g. follow the camera) and stream chunks in and out.
chunk_sizeintegerread-onlyCells per chunk axis.
cell_sizenumberread-onlyWorld units per cell.
loadedintegerread-onlyNumber of chunks loaded right now.

Methods 3

VoxelWorld:palette

method
VoxelWorld:palette(index: integer, opts: voxel.PaletteOptions)

Define a palette material shared by every chunk: updates the world palette and every loaded chunk; chunks loading later inherit it.

Example
-- Every chunk shares it: those loaded and those still to come.
world:palette(1, { color = datumhue.color("#a7c080") })
world:palette(2, { color = datumhue.color("#dbbc7f"), light = 15 })

opts voxel.PaletteOptions options 7 keys

KeyTypeDefaultDescription
colorColordatumhue.color(1, 1, 1)Base color; tints the tile when textured.
emissiveColorthe entry renders litEmissive color: entries with one render unlit at this color (channel values above 1 feed bloom).
transparentbooleanfalseTransparent entries render alpha-blended and don't occlude neighboring faces.
lightinteger0Block-light emission level 0..15: cells of this entry glow and light their surroundings, falling off one level per cell.
textureinteger | voxel.TextureFacesthe faces show frames, or the color aloneAtlas tile for every face, or a tile per face. Needs an atlas bound via voxel:atlas. At most one of texture / frames.
framesinteger[]the faces show texture, or the color aloneAnimated tile sequence shown on every face, advancing at fps.

VoxelWorld:chunk

method
VoxelWorld:chunk(coords: Vec3) -> VoxelChunk?

The loaded chunk at integer grid coordinates coords, or nil while it isn't loaded.

Example
-- Coordinates count chunks, not cells. nil until the chunk has loaded.
local chunk
repeat
    datumhue.time.wait_frames(1)
    chunk = world:chunk(datumhue.math.vec3(-1, 0, -1))
until chunk
print(chunk.voxel.pos) --> vec3(-16.0, 0.0, -16.0)
chunk.voxel:fill(0, 0, 0, 15, 0, 15, 1)

VoxelWorld:remove

method
VoxelWorld:remove()

Remove the world and every loaded chunk.
