--[[ This mod registers 3 nodes:
|
|
- 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)
|
|
|
|
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.
