20w12a adding the redstone after the fact doesnt make the pistons go up either |
| Comment by RedCMD [ 27/Feb/20 ] |
Vanilla:Glowstone should possibly not show redstone wire on its side since all other blocks which only transfer a redstone signal upwards have no wire on their side. This seems WAI because there is a check specifically just for glowstone
Visual Fix:Change the direction redstone visually faces matching the logical direction
Logical Fix:Change the direction of dust logically to match vanilla visuals |

@Fabian Röling: Minecraft 1.0 (1.0.0-RC1): The single redstone dust texture changed from a + to a dot. From this on it doesn't look like it is connected to all 4 adjacent blocks anymore but it still powers them. Minecraft 1.3.1 (12w25a) until Minecraft 1.8: Redstone can now be placed on upside down halfslabs. It is possible to create what we see in the 1.8 picture. While it is irritating, it is still consistent with other behaviour, because we know, that the dot represents a connection to all 4 sides (while not showing them). Since Minecraft 14w46a: The redstone now connects to the redstone on the slab, but still not to the pistons making it super counterintuitive why it powers them. It really should have stayed a "+" in the first place. (About the other mentioned issue of the redstone not going up the side of nonsolid blocks: In my opinion thats already how it's supposed to be, because it corresponds to the signal going up the block, but not down. If one would now add the redstone texture on the side of an upside down stair/observer/glowstone/etc. that would make things even more mixed up and irritating.) |

This is not only about the dot, for example look at this picture: |
| Comment by Joram Brenz [ 05/Sep/17 ] |
|
In the older "redstone redirection - 1.8 behaviour.png" picture we can see, that the redstone used to be a dot. And the dot once was a cross. So I suggest fixing the issue by remerging it with the dot visualisation, and then getting rid off those inconsistencies together, by displaying connections to all adjacent blocks. PS.: Consistency helps a lot learning redstone. So I think this bug is not as unimportant as it might seem. |

Confirmed in version 1.12 the issue of redstone wire visual render not matching connectivity. wire_render_1.12.png |
| Comment by Marcono1234 [ 14/Feb/17 ] |

The redstone block bug (and observer block as well) might be intended. It looks like they act like slabs in the way that the power can only go up but not down. |

Changed the whole description to match the fact that only two of the screenshots are currently how it's in the game currently. In that process I also shortened it quite a bit, if someone wants to look if there's something missing, there's a "history" tab above the comments. |

The description should be accurate. Old screenshots may still be attached. |

@[Mojang] Jeb (Jens Bergensten): This is how the redstone is supposed to be when it goes up to a slab or transparent block (only those who can handle redstone of course): This is the current visual glitch: NOTICE that the pistons are powered, it is INTENDED, don't change how the mechanic works BUT how it looks. |

Yes Pixie, but as I said, the redstone dust on top of the slab *is not powering the redstone next to the slab*. Redstone dust does not connect to pistons, they are not a power source. They do connect to redstone torches, as they are a power source. An exception to this rule is powering redstone through blocks. |

Because redstone dots can power the block next to them but it can not power redstone dust on top of that block. So if it is going to power redstone dust on top of a slab next to it it should be a line, the same as if it was going up a solid bock. (Atleast this is what i expect it to do) |
| Comment by [Mod] redstonehelper [ 03/Jan/16 ] |
|
Because when redstone dust powers other redstone dust most people expect them to be connected. |
| Comment by DicoTheRedstoner [ 03/Jan/16 ] |
|
If you read my earlier comments, you would know why this is. Redstone connects to sources of power, not to power destinations. |
| Comment by Pixie [ 03/Jan/16 ] |
|
Wouldn't it be that the single redstone line leading to the slab powering to the side like a dot be the bug rather then the other way around? Lines don't power to the side and redstone is suppose to point to connections. The connection in this case being up the slab, or other bock the acts like a slab. Also dots (and lines into blocks) do not transmit power up. So I believe that the line into the slab is correct, and the line powering like a dot a well is the bug. |
| Comment by DicoTheRedstoner [ 01/Jan/16 ] |
|
The redstone dust next to the slabs in that pic should be a dot, as it powers to the side as well. For the rest though, thats new behaviour, where it connects through unsolid blocks. |
| Comment by james magnusson [ 01/Jan/16 ] |

Seems to work as expected in 15w51b for the most part. Redstone dust connects through transparent blocks and transparent blocks that can have redstone put on them act like slabs (stairs, hoppers). Redstonedust still does not run down the side of redstone blocks but redstone blocks are power sources so I don't think it really matters. Don't know if it affects anything but I am using java 9 |

@dicotheredstoner: I added a bullet point about your screenshot, did I describe it accurately? Do you suggest any changes to the description? |
| Comment by [Helper] Michał [ 16/Nov/15 ] |

i don't think that it can be fixed, because redstone signal on some blocks can travel only up, but can't travel down. How to show this? |
| Comment by DicoTheRedstoner [ 16/Nov/15 ] |

@[Mod] redstonehelper Thanks for the cleaner overview of what the report is about. Redstone does render going up onto glowstone blocks in 1.8 (see screenshot: "Redstone redirection - 1.8, up onto glowstone"), which makes it more confusing indeed because glowstone has the same properties when working with redstone dust (you cant place comparators/repeaters on top of it though). Another bug you could make a separate label for... |

@jeb: I reopened this because not the whole issue was fixed. Here's a tl;dr of the issues this ticket is about:
I won't go into the issues caused by your fix, see dicotheredstoner's comment for that. In short, it's even more confusing now. For the future: If you only fix part of an issue, leave a comment explaining that so tickets aren't reopened even if you consider them done. I will leave this one open so you can decide what to do with it. In my opinion it'd be best if the whole fix was undone and the ticket marked "Won't Fix". |

@Jeb, sorry for the long post again, but I'd really like you to read this. I wrote a clarification of how it works, how it used to work and how it should work, as I did on the bug report of the redstone blocks ( When redstone dust goes up on a slab, as you know, it acts as a diode. Redstone power does go UP, but it does not travel back DOWN. Redstone always points towards power SOURCES or where its powered FROM. Thus, the redstone on top of the slab is redirected towards the source next to the slab, but the redstone next to the slab is NOT receiving power from the redstone on top of the slab and doesn't redirect. (Or stair, glowstone, lamp, anything). Besides - you don't seem to be aware of this - the redstone next to the slab still powers in all directions (if its not redirected from elsewhere). This is still the case in 14w46a (See screenshot "Redstone redirection - 14w46a behaviour") and, once again, has been the case since you could place redstone on glowstone and other non-solid blocks. This is such a fundamental component of redstone that I consider it something that should stay untouched, as the fact it works this way has been used in designing many, many, many redstone things. I wasn't aware in the last post that redstone still powers in all directions even when it has a slab with redstone on top of it next to it (and its redirected now), which I am very relieved about. But that's what makes this change so weird. On another note, this bug was mainly meant for something else to be fixed - the behaviour in "screenshot 2". Diamond blocks are solid blocks and the redstone goes up and down. The blocks at diagonal that seem to block the redstone's path are not solid blocks, and thus they do not block the redstone's path. The glitch here is that the redstone does appear to be cut, but 'logically' as the reporter names it, it's not, and the redstone doesn't power to the side of it (As shown in "Redstone redirection - blocking with leaves"). This is definitely a bug. I'll mention this again, redstone always points towards where it's powered FROM (unless powered from directly above/below, or through a block). If it's a dot, it powers in all directions, and if it's not, it powers on the side adjacent to where its powered from. When it's powered from 2 sides, it doesn't point 'into' or power any side. So, I suggest, once again, that you revert this bug to what it was as well, and fix the situation shown in "screenshot 2". |

Why was this reopened? I fixed the old report and this is a new problem that should be "won't fix", but I don't want to change this report to "won't fix" because it was fixed! Redstone dust should not float in the air, but dust on the ground should point to connections. |

I doubt this is intended because it's inconsistent as True Kuehli pointed out. Confirmed in 15w40b. |

It's the same with glowstone and slabs i think. We will see what will happen with redstone when jeb rewrites the whole thing. DOn't expect this to be fixed before 1.5 |
| Comment by True Kuehli [ 05/Nov/12 ] |

But with Glowstone and Leaves there's no Redstone on the side of the upper block. If you put there glass instead of the Leaves it's connected on the side, so I don't think it's a feature... AND: It's shown as a redstone-point, but it still works as a redstone-line. |
