Why this page has been deleted ?
Notch really said "[...] I worked on a map item for minecraft today[...]"

Valuable info, but one twitter post is not enough to warrant its own article until we have more information. It's on the upcoming features page though. --Theothersteve7 15:20, 21 April 2011 (UTC)
 * Have you seen his blog? He is getting pretty far on it.Cool12309(T 02:32, 28 April 2011 (UTC)


 * Have you seen the date of that post? A week ago. Notch had only said "I'm playing with maps" at that time. – ultradude25 ( T at 03:37, 28 April 2011 (UTC)
 * What have you been smoking? The post was made YESTERDAY. Cool12309(T 21:03, 28 April 2011 (UTC)


 * 21 April 2011 (UTC) was not yesterday. – ultradude25 ( T at 03:23, 29 April 2011 (UTC)

 * What has Notch's blog post got to do with this? I'm talking about this page... – ultradude25 ( T at 05:44, 29 April 2011 (UTC)


 * Notch said so himself that he's adding maps (and they're confirmed), and they're the only new item in 1.6 On his tumblr page; that's what cool was talking about. --R ocĸetor talk  06:05, 29 April 2011 (UTC)


 * Theothersteve7 said 1 twitter post isn't enough for an article on the 21st, when Notch had only made that single tweet about playing with maps, then Cool12309 says "have you seen his blog" on the 28th. My point was at the time Theothersteve7 posted Notch hadn't made the blog post Cool12309 was referring to... – ultradude25 ( T at 07:21, 29 April 2011 (UTC)


 * This wiki is not wikipedia. If you wish to impose their stringent rules, go there. For the rest of us, it is entirely appropriate to ready a spot for upcoming items.  --BreenWhitman 22:46, 29 April 2011 (UTC)

French version
Hi, in the French wiki we have made quite a nice page for the map item since the last post from Notch. Feel free to translate it (Google translation). It also has a temporary item image that can be reused. --Jimeowan 22:51, 27 April 2011 (UTC)

Ideas
I know this isn't a suggestion page or anything, but i need to get rid of some thoughts somehow. For once, i would welcome it if a you could erase a map to set zoom/center again. Additional to that, if the last map item using a set of map data is erased, the map data should be deleted as well (that would be lighter on the limit on maps, and allow much room for experiments). A map item getting destroyed in a fire or otherwise removed should "delete" it, too. –The preceding unsigned comment was added by BlueLegion (Talk 16:06, 28 April 2011. Please sign your posts with

Can we please change the item picture?
It slightly resembles a penis and I witnessed several people post about it on the forums. It should be changed to a less distracting image. –The preceding unsigned comment was added by Krunchyman (Talk 03:25, 30 April 2011. Please sign your posts with

more ideas...
A couple of randomly-generated thoughts, paralleled on the forums but added here as well...

These should be a no-brainer. Maybe limited to a certain amount of pages? Right-click on a book in your inventory to open a GUI allowing you to choose which page to look at. Maybe use the player's current X-Y position to automatically open to the right page in your book? Once placed into a book, maps can not be updated/edited/added to. And the ability to title books would be invaluable. Book of Northern Sea Charts, anyone?
 * Map Books

Is there some way a map could include a Cartesian notation, say a small watermark in the corner giving the map's center-point in integer X-Y values? This would make serious cartography a little more organized, and map selection wouldn't be based on trying to recognize a particular terrain form...
 * Map Co-ordinates

The ability to manually add up to (say) 6 or 8 'tool-tip' points to a map while creating it would be another invaluable tool. Perhaps a certain key pressed while holding the map could open up a GUI for the addition of a small amount of text, which would then appear as a 'point' on the map at that location.
 * Map Points-of-Interest

These should be chosen from a set number of pre-defined values at creation, IMHO. Although, I don't necessarily know what those values should be to create (for example):
 * Scaling, Zoom
 * a local-area map of (say) 100&times;100 blocks
 * a mid-range map of 500&times;500
 * a long-range map of 1000&times;1000
 * a 'super map' custom-scaled to show all explored surface terrain

Right-click on a map displayed in an open book to show a larger version of the map as a separate GUI, to allow for Point-of-Interest selection (see: Maps as Waypoints, below)
 * Map Interactivity

Selecting a Point-of-Interest on an open map would over-ride the Compass from showing the original spawn-point to showing the heading from player to the POI, making the humble Compass far more useful than it is now. Include a 'reset' function to reset the current waypoint to the Original Spawn point.
 * Map Points as Waypoints

any feedback on this would be appreciated! Aethir 15:14, 11 May 2011 (UTC)


 * The wiki isn't the place for random speculation/suggestions for in-game stuff; it needs to be kept to the forum. 「 ダイノ ガイ 千？！ 」? · ☎ Dinoguy1000 00:11, 12 May 2011 (UTC)


 * - and yet, the discussion page previous to my post was mostly filled by random speculation about 'penis maps', which didn't earn a similar reprimand? And what else would a 'discussion' be about, if not to throw about ideas relating to the topic? It's not, for example, a 'bug report' page. I fail to see how a reasoned discussion about implementing new ideas is somehow not relevant to a discussion page. Aethir 03:04, 12 May 2011 (UTC)
 * The chances that someone from Mojang will read this talk page are about a trillion to none, therefore this is not the place for new ideas. The previous topic wasn't speculation; it was a ridiculous complaint about an innocent image marginally resembling something suggestive. The discussion page is usually best used for working on the article itself, to some extent theorycrafting, or confirming with other players about a feature or bug. - Alphap T ~ C 03:32, 12 May 2011 (UTC)
 * - See, that wasn't so hard to outline, was it? Your point is duly noted. Aethir 03:42, 12 May 2011 (UTC)

Naming maps?
I've noticed in Notch's new trailer with maps that the map he uses is labeled "Test" at the top. Has there been any prior speculation as to wether or not naming maps would be enabled? If so, I think it would be extremely useful, and also when writing books and making paintings in the future. Alien holiday 19:52, 24 May 2011 (UTC)


 * I don't think anyone considered the possibility (and I didn't notice any name myself; I'll have to rewatch the trailer and pay attention), and so there wouldn't be any relevant speculation. 「 ダイノ ガイ 千？！ 」? · ☎ Dinoguy1000 20:05, 24 May 2011 (UTC)


 * Can someone link to this trailer? I haven't heard of or seen it myself and it sounds worth watching Deanm 20:59, 24 May 2011 (UTC)
 * Official Minecraft Youtube Hub <- it's on there. Nothing spectacular but it does show off maps in use.  --Warlock 21:16, 24 May 2011 (UTC)


 * He mentioned that the naming of maps will be implemented later. --McTwist 05:30, 28 May 2011 (UTC)

No zoom level?
Well, after a bit of testing, it appears that the map has no zoom level options. I'll leave the discussion to whoever sees this, because it's fairly late (early?) where I am. Megabobster 09:35, 26 May 2011 (UTC)


 * I can't change the zoom level on mine either when I make them. I also can't change the name of it from map_01 or something like that Deanm 10:14, 26 May 2011 (UTC)


 * Does each map you make just pick a random zoom?Toadbert


 * Right now each map has a set zoom(scale) level. It is discussed here how it really works. --McTwist 05:38, 28 May 2011 (UTC)

Nether maps
Do they work? Any bugs? I don't currently have any worlds with portals, so I thought I'd ask.
 * Not...really. The pointer goes all out of wack, the pixels are really hard to read, but it does update the map (slightly). It's just not very useful in the slightest. Fruckert 21:01, 26 May 2011 (UTC)

Glitch?
Dunno if anyone else is getting this but when exploring with my first map I couldn't be bothered to switch away to a spade so just removed some dirt with the map and the dirt block was still visible afterwards but I could walk through it, and any others I removed with the map. Anyone else getting this? This may not be related to just maps as I seem to be getting more visual problems with this update. --Watson690 16:32, 26 May 2011 (UTC)

Placeable on Walls?
Did this make it in? Just curious as I can't check myself at the moment :) --Warlock 17:07, 26 May 2011 (UTC)
 * Not in! Sorry to disappoint :) --Flippeh 19:31, 26 May 2011 (UTC)
 * Boooo, that's a shame. My plans for a hollowed-out volcano evil villian secret lair will have to go without a map from which to plot world domination :(  --Warlock 19:33, 26 May 2011 (UTC)

Internal representation / map data
So I wanted to use the stored map data to draw pretty pictures of it. Because why not.

This is what I found:

{   TAG_Compound("data") {       TAG_Byte("scale"): 3 TAG_Byte("dimension"): 0 TAG_Short("height"): 128 TAG_Byte_Array("colors"): [ <128x128 flat array of colors> ] TAG_Int("xCenter"): -228 TAG_Short("width"): 128 TAG_Int("zCenter"): 642 } }
 * Maps are stored inside / /data/Map_.dat, gzipped NBT (as usual)
 * The internal structure of those files is...
 * The color values do not resemble blocks (didn't expect that either since 1 block on the map is an 8x8 in the real virtual world and deeper water would still be water)

Does anyone have an idea what those values could mean? I found out that 50 = one of the many blue shades.

For now I suspect that they have hardcoded the colors in a table or map inside the engine. --Flippeh 19:48, 26 May 2011 (UTC)


 * I made a quick check of how it worked and instantly said no to it to be color values. Both because it's in-game data, need less space to store at, and that it is too small to store color in one byte.


 * It isn't block types either, wonder why he isn't doing that, so it must be a color-table that is built-in in the game. Either someone decompiles the game and fetch the values, screenshot existing map while in-game, or use their own values. Even though, someone needs to add this to a page where it tells how it works. I might do that. --McTwist 09:13, 27 May 2011 (UTC)


 * He isn't storing the block types because water has more than one blue shade depending on water depth, so a lighter blue, a normal blue and a darker blue all represent the same block ID of water. At least that is my theory, I think that makes sense, since on my test map, 48, 49, 50 all represent water, and there are also multiple shades of sand and just about every other block. I'd too go with the built-in guess. --Flippeh 16:59, 27 May 2011 (UTC)


 * I suggest that we move this small conversation to the created Map Item Format article I created, and that I see you have edited as well. --McTwist 18:12, 27 May 2011 (UTC)

Names
How do you change the map name? Is that a multiplayer thing, or is it not in the game yet? Fruckert 21:07, 26 May 2011 (UTC)


 * There is already a section of this above. Even though, you should move this to the talk page of Talk:Map Item Format as that might answer you questions.
 * Also, naming maps was a feature Notch were supposed to add, but he did not for now but he said he will probably add it in next version. --McTwist 05:24, 28 May 2011 (UTC)

Colors
Gonna start getting these Blue - Water

Light Blue - Ice

Tan - Sand, Slowsand

Brown - Dirt, Wood & products

Gray - Stone, Cobblestone, Sandstone, Obsidian, Lightstone, Metal Blocks, Bedrock, Spawner, Sponge White - Snow, Snow block

Light Green - Grass

Dark Green - Leaves

Bright Red - Lava, TNT

Leetskillz 23:44, 26 May 2011 (UTC)


 * I would suggest you take this to Map Item Format as that have a table with colors but needs descriptions. Also take a look at the talk page where we discuss what color is what. --McTwist 05:22, 28 May 2011 (UTC)

Void Glitch
Alright, I just encountered the glitch where having void in the map crashes the game whenever I get near the area with the map open. Surprisingly, this seems to happen even though the 2X2 hole that I edited into the bottom layer of bedrock is far underground and completely covered by several layers of solid blocks. (?) Now, I tried fixing this by plugging up the bottom layer hole, but the game still crashes when I pull up the map anywhere nearby to update it. Is there anyway to fix this, or do I need a whole new map? Do I need to plug up the hole with bedrock for it to work? Thanks.

Videos
Ok, I've not really any idea what to do here, being a relatively new contributor to the wiki. I've been using it for as long as I've had Minecraft and it's been smashing, so when the new release came out I decided to contribute some tutorial videos to this page and the Trapdoor page. Minutes later the one on this page had been replaced, then removed when I put it back. I don't know if I'm doing something wrong by putting a tutorial video up, I'm complying with Rule16 and making sure there's nothing wrong with the video. I don't yet know how to get the video up on a thumbnail, but first of all I'd like to ask why my video has been taken down, yet again. Toby1066 13:15, 27 May 2011 (UTC)Toby1066

Icons
Aside from the paper, it also has an image file for the icons, "minecraft.jar/misc/mapicons.png". Featured are a white 'x' and 4 multicolored cursor icons, white, blue, green and red. So far I've only seen the white cursor, but am I to assume that the remaining 4 icons are placeholders for future features? I'm guessing that the X is either spawn or your bed, and the other cursors might be for other players or perhaps mobs. I've also noticed that the cursor, which shows which way you're pointing is off by about 22 degrees clockwise, or 1/8th of a turn. Each Icon is also off-center by a couple pixels too, though the map code might compensate for this. Ghost2 20:50, 28 May 2011 (UTC)
