/**
* Sets on Vector3 the data from a Block object,

* If $direct is true, it'll send changes directly to players. if false, it'll be queued
* and the best way to send queued changes will be done in the next tick.
* This way big changes can be sent on a single chunk update packet instead of thousands of packets.
*
* If $update is true, it'll get the neighbour blocks (6 sides) and update them.
* If you are doing big changes, you might want to set this to false, then update manually.
