This is because the enchantment table NEEDS 1 whole block to grab the stuff - the snow stops it - Put a roof over the room

I think this is working as intended. Not 100% sure.

Mustek 2012-11-08T14:50:40Z

Works as intended, there can't be any blocks obstructing the way between the table and the shelves.

Tim Hicks 2012-11-10T00:32:30Z

It's snow for cryin out loud, lol. would'nt call it a "block". Thanks for checking though.

David Harmon 2012-11-18T14:25:09Z

Snow is a block, it just doesn't fill its space. Torches have the same effect, and are more controllable if you want to do cheaper enchants.

Mushrooms block as well.

Marcus Koller 2013-09-22T16:17:19Z

I think its illogical that snow, carpet, or any block that doesn't take the entire block portion covers it. imagine you are building a home and carpet blocks you from opening your drawers? Makes no sense. I think snow and carpet should be an exception to this rule, specifically because carpet is used as a decoration! I hate seeing stone blocks near the enchantment table and everything else is carpet.

Ben Jackson 2013-09-29T00:33:04Z

This is a similar problem to carpets, I hope This and my Issue MC 33150 will be fixed

Marcus Koller 2013-09-29T17:40:43Z

Hate to break the news Ben, but they said this is normal and works as intended, so it will not be fixed. I personally would like to ask someone to put carpet between a table and a tv, let me know if it breaks vision. Logic of some of these programmers is sad. Carpet/Snow is a decorative item, and who would want the enchantment table room be not carpeted? I mean its not like we are asking them to do this with flowers too, and other blocks that do not take a whole block.

While it can be easily explained why, technically, it's behaving as it is. (it's a block, voxel pathfinding, etc.)

But is it really intended?? By answering yes to this question you're essentially agreeing that the developers sat down and said "You know what?! I think carpets should block line of sight of the enchanting table"

I respect the moderators attempting to filter things, but for bug reports to work, at one point you have to stop thinking as a programmer and try to see things from the perspective of the client/user/gamer. In whose mind, besides a programmer, does a carpet block line-of-sight?!

If you really want to get technical, in the code, a block of "air" is actually a block itself... so how is it not blocking line-of-sight?! Hint: It was coded not to.

As for "They have said it is working as intended". Who actually said that?! A Mojang employee? An Atlassian employee?! Who?! (Citation source needed!)

David Harmon 2013-11-09T16:13:03Z

Since the introduction of the enchanting table, the devs have been very consistent that any block, <i>including partial blocks</i>, between a bookshelf and the enchanting table, will block the bookshelf's effect. Carpets are a partial block, just like snow and torches. Just because their hitbox and texture are small and flat, does not change this. Neither does their transparency.

Just because you, personally, don't like how something behaves, that does not make it a bug. If you absolutely must have a colored floor between your enchantment table and bookshelves, you are free to replace the floor blocks themselves with wool.
