Talk:Opacity/Placement

Include a history section?
Should we include a history section on this page? I'm leaning towards no, as it would require a lot of research to go back and document old changes. Maybe have a note at the top of the history section that it only catalogs changes from 1.14 onwards? -PancakeIdentity (talk) 23:57, 14 June 2019 (UTC)
 * Whenever you are asking the question "should History be added?" the answer will always be yes. – Nixinova Nixinova sig1.png Nixinova sig2.png 23:58, 14 June 2019 (UTC)

Should this page be integrated into main articles yet?
I just discovered this page's existence as a result of an edit to Redstone Comparator replacing some of its block placement limitations with a link to here. Based on WhatLinksHere, I assume similar edits were made to other pages. I question whether that's a good idea. Does it really benefit the reader to break up the list of block placement limitations, sending them to a separate page for just the transparent ones, where they have to find the information they need in a table that is mostly irrelevant to what they were trying to learn? As a reader, I find that quite annoying. I realize that avoiding redundant information makes the wiki easier to maintain, but it shouldn't be done at the expense of the reader's convenience.

I also question whether the page's scope is broad enough. It was created in 2015, when Java Edition was the only version, and it mentions no differences for other editions. I'd be astounded if all this information is accurate for all of them. I suggest that it shouldn't be integrated into articles intended for all editions if it isn't relevant to all of them, especially since it doesn't even mention that the information is only for Java.

I would also say that it needs more explanation about what's included in the tables. For instance, the table for "placing on top" includes columns only for certain blocks. I expected to find Brewing Stand there. Is that an accidental omission, or does it not fit the criteria you used to decide which blocks to include? The section should describe the criteria used to select blocks for its rows and columns. – Auldrick (talk &middot; contribs) 16:36, 22 June 2019 (UTC)


 * For the first point, I'd be open to adding the relevant info to each page, though I don't think this page should be removed. For the second point, this was created this year, and I am the only person who's really done anything with it. I don't have access to any other versions, so I wasn't able to add them here. If someone could help me expand this page, that'd be great. For the third point, I only included A) Blocks that actually had some sort of unique behavior (for example, glass wasn't included because everything can be placed on it) and B) Blocks that can't stand alone. Brewing stands don't need a support block, but blocks like a comparator do.


 * For placing this on each item's own page, I do worry that it adds too much technical info that most players won't really care about. I'd be open to it, but I think it definitely needs more discussion. I'll also work on clarifying what is actually covered on this page. -PancakeIdentity (talk) 18:59, 22 June 2019 (UTC)

move this page
If another block can attach to that block, we call that block a solid block. Attachment depends on whether it is a solid block, regardless of opacity. how about moving the page to solid block/Placement.--Chixvv (talk) 10:18, 20 July 2019 (UTC)


 * . This is under "Opacity" as that's the parent page that discusses transparency. In addition, None of the blocks here can be truly classified as solid. -PancakeIdentity (talk) 16:57, 20 July 2019 (UTC)


 * If so, the list of solid blocks needs to be changed, because now it doesn't depend on whether one block has a collision box, it just depends on whether other blocks can be placed on it.--Chixvv (talk) 00:10, 23 July 2019 (UTC)


 * This page is about how transparent blocks are placed on other transparent blocks. It does not cover anything with solid blocks. -PancakeIdentity (talk) 02:30, 23 July 2019 (UTC)


 * It seems misleading to have it be part of Opacity because while, yes, it does describe transparent and non-full blocks, the properties of each one that determines whether they will support another one is their solidity and their collision shapes. Joabroyt (talk) 06:59, 6 July 2023 (UTC)

Plant blocks
Should we include what blocks certain plants can be planted on in this article somehow? Granted, this would kind of take away from it being an opacity centric article, but I think that's justifiable and this could benefit form being moved to a mainspace non-subpage placement page. - User-12316399 (talk) 20:01, 9 March 2020 (UTC)

Also how about documenting item frame and painting placement? - User-12316399 (talk) 22:25, 9 March 2020 (UTC)


 * This page is pretty useless and should probably be deleted once we get the transparency stuff documented elsewhere. I mentioned it on discord, but my plan was a page discussing how the different face types work (full, sturdy, center, rigid). Then infoboxes could tell what kind of face(s) a block has and/or requires, and, if a block has further special behavior, there could be a section dedicated to it in its article. There's not really a need for the giant tables here. Plant placement should go on the plant pages, item frame placement should go on the item frame page, etc. -PancakeIdentity (talk) 22:37, 9 March 2020 (UTC)


 * Yes, this was part of my plan with inserting an Occurrence section into articles, as it would document how a block would come to exist within the world; natural generation, post-generational processes, and then the block's placement rules. The placement info would be therefore documented in the third subsection. I still personally think a page with tables like this one would be useful, though, as an overview of placement inconsistencies (as well as links to bug reports where appropriate). - User-12316399 (talk) 15:46, 10 March 2020 (UTC)


 * I'd be fine with a page to document inconsistencies specifically, documenting everything would just be too much. Though that would still disinclude plants and item frames from this page. -PancakeIdentity (talk) 20:33, 10 March 2020 (UTC)

Sea Pickles cannot be placed on glass
See this "Resolved:Works as intended" bug report: (MC-127998) (though I think in this case glass is solid, but transparent? so the bug report could be better worded)

This means the statement "everything can be placed on glass" in the intro is now incorrect and glass should be included in the table :)

I have confirmed this behaviour in Bedrock - I do not have access to Java but the "bug" report was filed against Java so I assume it is the case there too


 * Maybe placing a sea pickle is like planting a seed? You cannot do that on glass either. Amatulic (talk) 19:32, 24 September 2021 (UTC)
