* Gets the light value at the given position. Note that the light value

"inside" the node at the given position is returned, so you usually want

to get the light value of a neighbor.

* `pos`: The position where to measure the light.

|

* `radius`: using a maximum metric
|

* `nodenames`: e.g. `{"ignore", "group:tree"}` or `"default:dirt"`
|

* `search_center` is an optional boolean (default: `false`)

### `Raycast`
|
||||
|
||||
A raycast on the map. It works with selection boxes.
|
||||
Can be used as an iterator in a for loop as:
|
||||
|
||||
local ray = Raycast(...)
|
||||
for pointed_thing in ray do
|
||||
...
|
||||
end
|
||||
|
||||
The map is loaded as the ray advances. If the map is modified after the
|
||||
`Raycast` is created, the changes may or may not have an effect on the object.
|
||||
|
||||
It can be created via `Raycast(pos1, pos2, objects, liquids)` or
|
||||
`minetest.raycast(pos1, pos2, objects, liquids)` where:
|
||||
|
||||
* `pos1`: start of the ray
|
||||
* `pos2`: end of the ray
|
||||
* `objects`: if false, only nodes will be returned. Default is true.
|
||||
* `liquids`: if false, liquid nodes won't be returned. Default is false.
|
||||
|
||||
#### Methods
|
||||
|
||||
* `next()`: returns a `pointed_thing` with exact pointing location
|
||||
* Returns the next thing pointed by the ray or nil.
