Slabs Library

The builtin:slabdef library gives helpers for registering slab variants of regular blocks.

Importing

local slabdef = require("builtin:slabdef")

Functions

Function: slabdef.on_place(identifier) -> function

This function returns an on_place callback for a given slab identifier.

Arguments

• identifier is the namespaced block ID. If you omit the namespace, the engine uses core.NAMESPACE.

Return value

• A function that implements slab placement logic for block registration

Function: slabdef.add_block(identifier, prototype, options) -> integer

A wrapper around blocks.add that defines a slab block family.

Arguments

• identifier is the namespaced block ID. If you omit the namespace, the engine uses core.NAMESPACE.
• prototype is the base block definition the function builds on
• options is an optional table with extra parameters

Return value

• Numeric block ID

Notes

• The registered block family gets an orientation state and variants for top, bottom, and double.
• The function keeps the touch response values from the prototype unchanged. It only defines block collisions.
