--[[ This mod registers 3 nodes:
2017-02-14 01:33:58 +00:00
- One node for the horizontal - facing dropper ( mcl_droppers : dropper )
- One node for the upwards - facing droppers ( mcl_droppers : dropper_up )
- One node for the downwards - facing droppers ( mcl_droppers : dropper_down )
2017-02-14 01:15:51 +00:00
3 node definitions are needed because of the way the textures are defined .
All node definitions share a lot of code , so this is the reason why there
are so many weird tables below .
