RebarFallingBlock

Interface meant to be used for all Rebar blocks affected by gravity, like sand, gravel etc.

If you implement this interface, and the block can't fall, then the methods will never be called.

Beware of how you modify the passed data in the entity, because of the order of serialization and deserialization some modification need to be applied directly to the PDC stored in the entity, or they will be lost.

Also at some steps, the entity or the block might not exist yet in their relative storage, handle this interface with caution as it needs to handle state using internals most of the time.

As a suggestion, don't make important blocks with lots of data affected by gravity, or it might become a nightmare to apply the correct changes.
