• Incorrect use of ISidedInventory (Tube interaction with vanilla furnace)

Vanilla:          Bluepower:

   in                in        
    +                 +
  #####             #####
  #   #-out    fuel+#   #
  #####             #####
    +                 -
  fuel               out

• Interesting render glitch with wires using parts of my skin:

• The pipe routing isn't fully functional, color seems to have less priority than distance:

------------------------

|      |       |       |
|      |       |       |     <- everything goes red
in

Also, the bluestone wires shouldn't react to indirectly being powered.

" Incorrect use of ISidedInventory"

This is correct use of ISidedInventory. In Minecraft 1.5.x, when Hoppers were added, the sidedness of Furnaces changed to allow Hoppers to insert both fuel and smeltables, and output the processed items. This indeed doesn't match the mapping in the GUI.

Indeed, distance has a higher priority than the color. This is something more people don't realise. Coloring a tube only says 'items colored other than the tube color can't travel through this tube'. This means that any item with the same color as the tube or uncolored items can travel through this tube. If you want to increase the distance use a Restriction Tube.

The last problem probably is related to this as well, were the items in the last example uncolored by a chance?

And yes, we know of that bug where bluestone sometimes gets a random skin (still haven't figured out why it happens). It's already fixed in the multipart branch. ;)

1. This is supposed to be like RP right? If I recall correctly, the sides where mapped different back then but okay, if they changed in vanilla fine, wasn't aware of that.
2. No these items were colored. And it's a terrible idea to prioritize distance before color, how are you supposed to build anything compact like that? it used to be possible to build a row of chests with a tube line below and different colors for each chest, the items went straight through the colored tube into the connected chest. I can't really imagine building a sorting system like that...

           sorter
             |
     ----------------         VS   sorter
     |              |                |
  ---------     ---------            ----------------------
  |       |     |       |            |      |      |      |
 red    green  blue    white        red    green  blue   white
  |       |     |       |            |      |      |      |
chest   chest chest   chest        chest  chest  chest  chest

The left one is even worse than the equal distribution workaround...
How is this supposed to work with chests all over the place? With odd numbers of chests?

Trying to use the same terminology as you did might have been a bad choice on my part. What I should have said is that the tubes work exactly like RP's, with the exception that you can paint every side of the tube individually. You might have painted the wrong side of the tube. You want to paint a side the item is travellimg through (not the middle part).

RP wasn't ISided aware as far as I can remember.

Colour doesn't get prioritised at all, either in our tubes or in Red Powers, it just denotes whether or not something is a valid route. Uncoloured items can travel any coloured tube. If you have a red coloured item travelling a blue connection then that is a bug.

it used to be possible to build a row of chests with a tube line below and different colors for each chest

That is still possible, in even less space with Blue Power because we allow painting connections rather than entire tubes. Make sure you paint the connection into the chest rather than the centre of the tube as you look at it (that paints the connection that would be going towards you)

Ah, that's interesting... yes I had it in the center of the tube (just like redpower~) now it works, thanks for pointing that out! (Redpower didn't use ISided? Then how did they always pull from the slot I wanted? ^^)

You should find the new paint system opens a lot more possibilities (like 3 tubes through 1 block) ;)
