### Methods
|
||||
|
||||
* `is_valid()`: returns whether the object is valid.
|
||||
Objects may be invalidated either through explicit removal,
|
||||
or implicitly between server steps by the engine.
|
||||
**The below methods should only be called for valid objects.**
|
||||
* `get_pos()`: returns position as vector `{x=num, y=num, z=num}`
|
||||
* `set_pos(pos)`:
|
||||
* Sets the position of the object.
