# mcl_worlds
This mod provides utility functions about positions and dimensions.

## mcl_worlds.is_in_void(pos)
This function returns:

* true, true: if pos is in deep void (deadly)
* true, false: if the pos is in void (non-deadly)
* false, false: otherwise

Params:

* pos: position

## mcl_worlds.y_to_layer(y)
This function is used to calculate the Luanti y layer and dimension of the given y the reference game layer.
Mainly used for ore generation.
Takes a Y coordinate as input and returns:

* The corresponding the reference game layer (can be `nil` if void)
* The corresponding the reference game dimension ("overworld", "nether" or "end") or "void" if y is in the void

If the Y coordinate is not located in any dimension, it will return: nil, "void"

Params:

* y: int

## mcl_worlds.pos_to_dimension(pos)
This function return the the reference game dimension of pos ("overworld", "nether" or "end") or "void" if y is in the void.

* pos: position

## mcl_worlds.layer_to_y(layer, mc_dimension)
Takes a the reference game layer and a “dimension” name and returns the corresponding Y coordinate for VoxeLibre.
mc_dimension can be "overworld", "nether", "end" (default: "overworld").

* layer: int
* mc_dimension: string

## mcl_worlds.has_weather(pos)
Returns true if pos can have weather, false otherwise.
Weather can be only in the overworld.

* pos: position

## mcl_worlds.has_dust(pos)
Returns true if pos can have nether dust, false otherwise.
Nether dust can be only in the nether.

* pos: position

## mcl_worlds.compass_works(pos)
Returns true if compasses are working at pos, false otherwise.
In MC, you cant use compass in the nether and the end.

* pos: position

## mcl_worlds.compass_works(pos)
Returns true if clock are working at pos, false otherwise.
In MC, you cant use clock in the nether and the end.

* pos: position

## mcl_worlds.register_on_dimension_change(function(player, dimension, last_dimension))
Register a callback function func(player, dimension).

It will be called whenever a player changes between dimensions.
The void counts as dimension.

* player: player, the player who changed of dimension
* dimension: string, The new dimension of the player ("overworld", "nether", "end", "void").
* last_dimension: string, The dimension where the player was ("overworld", "nether", "end", "void").


## mcl_worlds.registered_on_dimension_change
Table containing all function registered with mcl_worlds.register_on_dimension_change()

## mcl_worlds.dimension_change(player, dimension)
Notify this mod of a dimension change of player to dimension

* player: player, player who changed the dimension
* dimension: string, new dimension ("overworld", "nether", "end", "void")
