### `PlayerMetaRef`
Player metadata.
Uses the same method of storage as the deprecated player attribute API, so
data there will also be in player meta.
Can be obtained using `player:get_meta()`.
#### Methods
* All methods in MetaDataRef
### `NodeTimerRef`

* `set_attribute(attribute, value)`:
* `set_attribute(attribute, value)`: DEPRECATED, use get_meta() instead
* Sets an extra attribute with value on player.
* `value` must be a string, or a number which will be converted to a
string.
* If `value` is `nil`, remove attribute from player.
* `get_attribute(attribute)`:
* `get_attribute(attribute)`: DEPRECATED, use get_meta() instead
* Returns value (a string) for extra attribute.
* Returns `nil` if no attribute found.
* `get_meta()`: Returns a PlayerMetaRef.
* `set_inventory_formspec(formspec)`
* Redefine player's inventory form
* Should usually be called in `on_joinplayer`
