block library

-- Returns block string ID (name) by index.
block.name(blockid: int) -> str

-- Returns block integer ID (index) by name.
block.index(name: str) -> int

-- Returns the id of the block material.
block.material(blockid: int) -> str

-- Returns the block name displayed in the UI.
block.caption(blockid: int) -> str

-- Returns integer ID by block position
block.get(x: int, y: int, z: int) -> int

-- Returns block state (rotation + additional information) as an integer.
-- Used to save complete block information.
block.get_states(x: int, y: int, z: int) -> int

-- Set block with specified integer ID and state (default - 0) at specified position.
block.set(x: int, y: int, z: int, id: int, states: int)

Warning

block.set does not trigger on_placed.

-- Check if block at the specified position is solid.
block.is_solid_at(x: int, y: int, z: int) -> bool

-- Check if block may be placed at specified position.
-- (Examples: air, water, grass, flower)
block.is_replaceable_at(x: int, y: int, z: int) -> bool

-- Returns count of available block IDs.
block.defs_count() -> int

Rotation

Following three functions return direction vectors based on block rotation.

-- Returns X: integer direction vector of the block at specified coordinates.
-- Example: no rotation: 1, 0, 0.
block.get_X(x: int, y: int, z: int) -> int, int, int

-- Same for axis Y. Default: 0, 1, 0.
block.get_Y(x: int, y: int, z: int) -> int, int, int

-- Same for axis Z. Default: 0, 0, 1.
block.get_Z(x: int, y: int, z: int) -> int, int, int

-- Returns block rotation index based on used profile.
block.get_rotation(x: int, y: int, z: int) -> int

-- Set block rotation by index.
block.set_rotation(x: int, y: int, z: int, rotation: int)

Extended blocks

Extended blocks are blocks with size greather than 1x1x1

-- Checks whether the block is extended.
block.is_extended(id: int) -> bool

-- Returns the block size.
block.get_size(id: int) -> int, int, int

-- Checks whether the block is a non-origin segment of an extended block.
block.is_segment(x: int, y: int, z: int) -> bool

-- Returns the position of the main segment of an extended block
-- or the original position, if the block is not extended.
block.seek_origin(x: int, y: int, z: int) -> int, int, int

User bits

Part of a voxel data used for scripting. Size: 8 bit.

block.get_user_bits(x: int, y: int, z: int, offset: int, bits: int) -> int

Get specified bits as an unsigned integer.

block.set_user_bits(x: int, y: int, z: int, offset: int, bits: int, value: int) -> int

Set specified bits.

Raycast

block.raycast(start: vec3, dir: vec3, max_distance: number, [optional] dest: table) -> {
    block: int, -- block id
    endpoint: vec3, -- point of the ray hit point
    iendpoint: vec3, -- position of the block hit by the ray
    length: number, -- ray length
    normal: vec3 -- normal vector of the surface hit by the ray
} or nil

Casts a ray from the start point in the direction of dir. Max_distance specifies the maximum ray length.

The function returns a table with the results or nil if the ray does not hit any block.

The result will use the destination table instead of creating a new one if the optional argument specified.
