New way of registering stairs.
The old one still works. Adding stairs becomes a lot easier, the groups, sounds and a lot more (see https://github.com/HybridDog/minetest_game/blob/stairsupdate/mods/stairs/init.lua#L150-L153) are added automatically to the stair.

stairs.register_stair({origin = string[, fixed_name = string, recipe = string, add_crafting = bool}, extradef])
|
||||||
-> Registers a stair.
|
-> Registers a stair.
|
||||||
-> subname: Basically the material name (e.g. cobble) used for the stair name. Nodename pattern: "stairs:stair_subname"
|
-> origin is the node the stair consists of, selected parts of the node definition of origin are copied and used for the stair, TODO: find out why it copies weird stuff although dumping the def of the original node (superpick mod) doesn't show them and try to avoid it
|
||||||
-> recipeitem: Item used in the craft recipe, e.g. "default:cobble"
|
-> fixed_name can be used to avoid giving the stair a name automatically, do not use it for register_stair_and_slab
|
||||||
-> groups: see [Known damage and digging time defining groups]
|
-> recipe is the craft recipe, if omitted origin is used
|
||||||
-> images: see [Tile definition]
|
-> add_crafting can be set to false to disable adding a craft recipe for the stair
|
||||||
-> description: used for the description field in the stair's definition
|
-> extradef is a custom node definition table, it can be used e.g. to give the slab a specific drop
|
||||||
-> sounds: see [#Default sounds]
|
|
||||||
|
|
||||||
stairs.register_slab(subname, recipeitem, groups, images, description, sounds)
|
stairs.register_slab is like register_stair but adds a slab
|
||||||
-> Registers a slabs
|
stairs.register_stair_and_slab calls register_stair and register_slab
|
||||||
-> subname: Basically the material name (e.g. cobble) used for the stair name. Nodename pattern: "stairs:stair_subname"
|
|
||||||
-> recipeitem: Item used in the craft recipe, e.g. "default:cobble"
|
|
||||||
-> groups: see [Known damage and digging time defining groups]
|
|
||||||
-> images: see [Tile definition]
|
|
||||||
-> description: used for the description field in the stair's definition
|
|
||||||
-> sounds: see [#Default sounds]
|
|
||||||
|
|
||||||
stairs.register_stair_and_slab(subname, recipeitem, groups, images, desc_stair, desc_slab, sounds)
|
For example, following code adds a stone slab and stair:
|
||||||
-> A wrapper for stairs.register_stair and stairs.register_slab
|
stairs.register_stair_and_slab({origin = "default:stone"})
|
||||||
-> Uses almost the same arguments as stairs.register_stair
|
The stair is named "default:stair_stone" and contains groups, sounds, etc. from "default:stone".
|
||||||
-> desc_stair: Description for stair node
|
|
||||||
-> desc_slab: Description for slab node
