 /**
  * Sets on Vector3 the data from a Block object,
  * does block updates and puts the changes to the send queue.
  *
  * 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.
  *

  * @param Block   $block
