Talk:Bedrock/Archive 1

I think I managed to break Bedrock
False, see below

During my tests, I managed to break bedrock 3 times. To do so here are the exact steps I followed:

- Launch your Minecraft game with the following command line: javaw -Xmx7144M -Xms1024M -jar Minecraft.exe

(You can set more than 7144M if your computer can handle it)

This will avoid the "Minecraft has run out of memory" error.

- Dig a 1x1 hole starting from the surface and ending at the bedrock. The hole must not go through any cavern (well, actually I never tried but I think it will raise the chances of success)

- Using Single Player Commands, type /brush sphere tnt 6

(You must have a tool like a wooden sword to use this command)

- Place many TNT spheres to fill your hole, like this: http://i.imgur.com/NhFEc.png

- Break the TNT at the top of the column

- ???

- Profit

At first I though one of my many mods had something to do with it, but using a fresh minecraft.jar gave me the same result. To avoid user errors, I uploaded a world with some TNT already placed. Here it is: http://www.megaupload.com/?d=GW23MAL2

I used a 2500k@4.6Ghz with 8GB of memory, and Minecraft 1.6.6

Here is the result (on another map) I had: http://i.imgur.com/2QvcA.png

Then maybe there's another reason but I now think the bedrock is breakable in Minecraft.

EDIT: Actually someone told me that placing TNT using SPC will ignore the bedrock and replace it. Mystery solved. –The preceding unsigned comment was added by Shuny (Talk 10:38, 6 June 2011. Please sign your posts with

Bedrock and hitting with hands/tools (was: -1 can be reached)
When a number in Java reaches it's maximum value and is increased by one, it will be the minimum value afterwards, so theoretically you can mine bedrock long enough. --Ftzhbv 11:30, 31 March 2011 (UTC)

Lets clear this one for good... All in all, hands or any tools, bedrock does not break, ever. I already added this info to the actual page. -- Bugi74 12:14, 19 April 2011 (UTC)
 * The damage counter is a floating-point value; it does not overflow that way.
 * The damage added per hit is typically very small, less than 1.0, and once the accumulated damage reaches 1.0, the block is broken. (Even if this had been implemented with integers, the hit values would probably have been 1-1000000, and the break-point damage something like 10000000, so still no overflow/wrap around.)
 * A negative hardness value is handled by own special piece of code, which forces the damage per hit to be zero, so the accumulated damage never goes anywhere when working on such a block (and bedrock hardness is -1 as we all know).
 * There is even a tiny little addition for mouse click handling, where the target block is checked for being bedrock, in which case certain pieces of code are not executed.

Bedrock and explosions/TNT
The only ways (that I can think of) to proof it can be broken with explosions is to provide a world save ready for execution of explosion(s) that end up in a broken bedrock (at least if tried enough many times), or a very very elaborate explanation of source code. (Videos or screenshots are easy to fake, so they do not proof anything, but they can be used to explain easy test cases to try).

(This is a reply to 'Youtube vid of bedrock being broken', but since it is no longer about the video, I made this new section with better name for this:) After quite a bit of reading of the source code (version 1.3.something), I also came into the understanding that explosion damage does not stack/accumulate, not even for single "damage ray" of single explosion, let alone different rays or different explosions. Also, the damage is not recorded anywhere, the test is simple: calculate explosion's remaining power at next test spot along the ray; subtract a value derived from the block's resistance from that power; if there is any power left, the block was not strong enough and is marked for destruction; if the power became less than zero, the block was able to withstand (and stop) the blast, and nothing is done the block this time, and forget that anything was even tried to be done to it. Caveat, I didn't debug/trace that code while exploding things to check for real runtime values and operation, so there is still a small chance... but I'll spend more time on this issue only if I see suitable proofs or test cases (i.e. a save file ready to be executed for "big bada boom") or source code snippets with interpretations that indicate I could be wrong. -- Bugi74 12:38, 19 April 2011 (UTC)

Youtube vid of bedrock being broken
DO NOT REFER TO THAT VIDEO on the wiki page

Referring to the video titled Minecraft - Even Bigger Ball o' TNT. The existence and continued references to this video have caused a LOT of harm in any discussion about bedrock, making the few facts buried in a quick spin to 90% nonsense and "wows!". So please, until someone manages to prove the video legit (hint: impossible), or at least proves that bedrock could be destroyed with TNT, DO NOT REFER TO THAT VIDEO on the wiki page. Feel free to discuss about it on the forums or on this talk page (see below). -- Bugi74 16:37, 20 April 2011 (UTC)

Are we sure this vid wasn't faked with a map editor? There was much debate on reddit about this.
 * It was the general consensus that it was indeed done with a map editor for a couple reasons. One of them being the fact that  because this was done on a frozen lake, the first TNT blocks to fall would expose the stationary water below.  Not only would this prevent TNT that fell into the water from destroying blocks, it also makes the massive dry crater impossible because TNT cannot remove water or lava source blocks.  The other main issue is that even if is possible to destroy bedrock with TNT, it is highly unlikely that the explosions from individual blocks of TNT would carve out a perfect sphere like the one shown in this part of the video.  On the other hand, clearing a sphere of all blocks (including bedrock) is a common feature in Minecraft map editors.  When all this is taken into account, it becomes pretty clear that this section should either be removed or reworded to reflect the dubious authenticity of the video. Dailyapple 16:38, 19 January 2011 (UTC)

It is not a perfect sphere, also, it should be considered that lag may have made this happen. The upper half of the ball certainly did nothing to bedrock, and the lower half is not 360,000 blocks. I think that if someone made that size ball, detonated it and as it was blowing up about 250 tnt blocks around a piece of bedrock also blow up, the bedrock would be destroyed due to lag glitching its explosion resistance. Someone should remake this video with a rectangular tnt area to disprove or prove the map editor theory. Bobbobbob 07:12, 8 April 2011 (UTC) bobbobbob


 * There is nothing to be proven or disproven here. Anyone who has played with largeish quantities of TNT knows that craters left from large TNT explosions are anything but "clean". And yes, a sufficient quantity of TNT *could* destroy bedrock, but said quantity would crash Minecraft every time, regardless of what computer was running it - MC simply isn't designed to be able to handle large explosions. 「 ダイノ ガイ 千？！ 」? · ☎ Dinoguy1000 15:29, 8 April 2011 (UTC)
 * I don't see how TNT could destroy bedrock, period. The way the code looks, explosions are completely independent of each other, ie. two explosions do not cause twice the damage to a given block, but rather that one amount of damage twice, even if the two explode at the exact same moment. Damage on blocks does not appear to accumulate, nor do blocks appear to have a "temporary health" value as was previously believed. If someone with more understanding of the code could step in and verify this, it would help quite a bit. - Alphap T ~ C 08:18, 12 April 2011 (UTC)

Breakable
I think it's breakable. Once I made mountain with an absurd ammount of TNT. We (it was in a SMP server) have a base with two floors, the first one made of obsidian and the second one made of bedrock, the obsidian floor was blowed up and we saw a floating bedrock block, we were able to collect it

 * The map is 128 blocks tall, from top to bottom, the bedrock at the bottom is 6 blocks thick (spattered), and sealevel is at 64 blocks.

The Nether
I think that the nether has two layers of bedrock - one at the ceiling, one at the base. Can anyone confirm this? Sompresneo

It does, you don't take void damage from getting over ceiling bedrock. Calinou 21:27, 23 March 2011 (UTC)

When you go above the bedrock in the nether in creative mode, there's this really weird thing where there are small random patches of slightly off-colored bedrock. If you mine one of the odd-colored blocks, any others adjacent will revert to normal, and continue so in a chain reaction until all are normal. Anybody else get this?


 * Yes, it's just a lighting bug from being above the maximum level or something. I doubt it'll ever get fixed since you're not supposed to be able to get up there, though. 「 ディノ 奴 千？！ 」? · ☎ Dinoguy1000 00:50, 3 October 2011 (UTC)

Amount of TNT needed to break Bedrock
On the page it says Bedrock is so solid it would take 4.5 million TNT to break. Where does this number come from? Is it real? JesusChrist666 02:56, 3 March 2011 (UTC)
 * Someone must've assumed that since TNT has 4 block resistance, it does 4 damage. TNT actually does 50 damage at best. Alphap 19:31, 3 March 2011 (UTC)
 * So can we get a revised idea? Is it physically impossible to deal that much damage simultaneously to a piece of bedrock? Darkid 02:38, 11 March 2011 (UTC)
 * Well, you've just posited a great 'craft scientist question. I could sketch you out a test you'd have to try via mod, I suppose.  First, work out how far (in levels) TNT will drop on activation before exploding.  Then, place a bedrock block in a shallow (say 1x5x5) depression.  Make a ring of TNT around that bedrock piece (so 8 blocks).  Continue that ring, layer by layer, up to the maximum distance the TNT will fall on activation before exploding.  Rig the TNT tower (somehow) to activate all at once (not entirely sure this is even possible) so that the entire hollow stack of TNT will fall down into the depression around the bedrock piece.  Press the button, and wait for the smoke to clear (or your computer to reboot).  If block remains, then the answer is likely no (although you could also place a 2-block high pillar of TNT beneath the block and above it too, although lord knows how you're going to activate that at the same time as the rest of the stack).  This setup should keep all the TNT in one place (mostly) and reduce the "It's raining TNT!" factor a bit. -Wulfenbach (not on fire for once) 08:56, 11 March 2011 (UTC)


 * (Edit note: There's also the Machinima interview where Notch more or less details that it's functionally indestructible, however you can apply the above to obsidian blocks, if you're looking for that sort of fun. -Wulfenbach (not on fire for once) 09:00, 11 March 2011 (UTC))


 * I'm sure you can explode a whole tower of TNT simultainiously using some redstone, But it'll probaly crash your computer after it explodes--Blueblade11 10:54, 21 April 2011 (UTC)

Inaccuracy
Using half my cobblestone supply, i made a climbable tower to the roof of the nether and there was earth bedrock. I'm going to change that.

TNT will not break bedrock
For a completely unproven account, I used a map editor on a map of mine to place a solid area of TNT with something like 30 blocks to a side (that is, a 30x30x30-block area, more or less) and detonated it. I started this in 1.4 or 1.5; Minecraft kept crashing, so I put it on hold until the release of 1.6, at which time I was able to change the video settings so that Minecraft stopped crashing (though it was still slow as hell until the explosion finally finished up). Once the explosion *did* finally stop, I checked the bedrock. Not a single block of it was gone, minus those blocks that had been displaced when I edited in the TNT (though the cavern I was using (originally carved out with TNT!) was considerably larger than it had been).

As I said above, though, this is a completely unproven, and largely unprovable, account; I never took any screenshots at any point and I don't think I'm going to repeat the experiment, though I still have the map. 「 ダイノ ガイ 千？！ 」? · ☎ Dinoguy1000 02:36, 8 June 2011 (UTC)

Another Possible inaccuracy
I run a multi-player server and commonly use the /give command. Just today (7/13/11) I placed bedrock using not /solid (which I have never used), but /give 7. 7 being the data value of bedrock. It did not disappear or act unusual at all. I don't know what the problem is here, but somebody got something wrong.

Fuming bedrock
Is it just me, or does bedrock emit fumes (or, more appropriately, little dots) as of 1.8 pre-release? Could that indeed be what has been «accidentally done» to the bedrock layer? -- Realward Nameson, 212.27.21.0 07:04, 13 September 2011 (UTC)


 * The void has a particle field effect, so that might be leaking through into the bedrock. I don't know if that's intentional or not though. – ultradude25 ( T &#124; C ) at 07:36, 13 September 2011 (UTC)

Bedrock is in classic

 * Maybe you also missed the part mentioning that what you see is not actually bedrock, but just a surface that looks like bedrock. Thus, to me, it seems that classic does NOT have natural bedrock, just something that looks like it but doesn't work as bedrock. Someone with facts might want to step up; I haven't ever touched classic. -- Bugi74 22:19, 16 September 2011 (UTC)


 * There is no natural Bedrock in Classic. What can be seen beyond the edge of the map is just a surface with Bedrock texture; when you point the cursor at it and it's within striking range, there is no block outline on it. In addition, you can't place other blocks directly on the walls or floor; in order to place a block immediately adjacent to them, you have to place it on another block. 「 ディノ 奴 千？！ 」? · ☎ Dinoguy1000 08:03, 17 September 2011 (UTC)

TNT does break bedrock
My friend Tama63 and I mined down to bedrock, and built a large sphere using WorldEdit. We then detonated it, and found a series of holes in the bedrock where the most concentration of the TNT was. I'm sorry I don't have screenshots, we filled up the holes right away. If it happens again (more than likely) I will gladly provide video (actually, my computer does not allow me to record, so Tama63 would record). --Dcomando15 03:54, 5 November 2011 (UTC)
 * Did you make sure there were no holes in bedrock before you started detonation (i.e. digged every single non-bedrock block, including lava, away)? Are you sure you didn't accidentally build the sphere of TNT too low, replacing some bedrock blocks with TNT blocks? Most importantly, do not bother providing a video or screenshots as a proof - they can never be a proof (read this talk page through for reasons). Instead, just before detonating, take a backup of the world, and if you do end up getting holes, then provide that backup for everyone to play with by themselves. This is the only empirical way it can be proven. Bugi74 10:24, 5 November 2011 (UTC)

 * That doesn't count as "breaking" bedrock, I think, so much as exploiting not-fully-tested behavior (though at this point I'm arguing from semantics =D ). It's a bug, at any rate, and I wouldn't depend on it going unfixed. 「 ディノ 奴 千？！ 」? · ☎ Dinoguy1000 22:54, 20 November 2011 (UTC)

I also managed to break bedrock with TNT
I promise, there was an explosion, and I saw it break; there were collectable bedrock items everywhere. This took place on an SMP bukkit server in a handmade bedrock sphere spanning to both height caps. My first thought was that it was a bug with bukkit or one of its plugins, since it won't work on SSP. Which is why my contribution to the bedrock page was not cited. My next thought was that it wasn't a bug and that the explosion rays were somehow focussed onto the ceiling, since the explosion was a square of TNT placed at the bottom of the sphere, but I later did tests to see if explosion rays can even be reflected (and it turns out they can't).

 * That has no bearing on the vanilla game, even if it is true, because no vanilla explosion comes within orders of magnitude of being as powerful as that, and I have reverted the edit that added it.

Method
Using WordEdit I generated a 3x3 shaft of bedrock from lvl 0 to 64. The shaft was blocked at lvl 0 and at lvl 52 with a piece of bedrock. Then I build a 5x5 stair that would lower one block every quarter rotation around the center of the shaft from lvl 64 to lvl 52. At every step of the stair I put a piece of bedrock that connected the stair to the shaft. I wired the entire stair and the pieces connecting it to the shaft with redstone. On the block directly after every second "step" of the stair I put a repeater with a delay of one. I powered it with a single redstone torch at lvl 63. This made every single block in the center of the shaft from level 53 up to lvl 64 a valid "ignition" spot for TNT. I then used the WorldEdit selection to select lvls 64 to 53 of the shaft. Then I built a 5x5 platform of bedrock at lvl 65, leaving a hole in the center, so the center of the shaft was open to the sky. Then I used the command //set 46. Filling the shaft's lvl 53 to 64 with TNT almost instantly. Since every block in the shaft was a valid iginition spot for the TNT, it ignited immediately. As soon as I realised this, I repeated the command //set 46. This caused more primed TNT to fall down to lvl 53 in the shaft. Since I have a chat mod on my client I was able to spam the //set 46 command a few times per second. This resulted in a fountain of primed TNT shooting up from the shaft and exploding in the air. However suddenly the entire shaft was gone, and I was looking down straight into the void. Even the top platform was gone, leaving only a few blocks of bedrock.

What do you think could've caused this? Could bukkit implement a different value for bedrock's TNT resistance? Could a mod have changed the bedrock resistance? (as far as I know none explicitly state they do.)

Holes in bedrock
They exist. Rare, and extremely unlikely to be found if you don't know what to look for, but they do exist, thanks to a flaw in the world generation algorithm. In my test map, generated entirely in release 1.1 (407,969 chunks, 1.7GB), 0.0128% of layer 0 blocks are not bedrock. In the lower parts of the world, there are small caverns, usually not connected to any cave system, with a few layers of lava on the bottom. They also have a floor made of the usual underground materials - stone, dirt, and ores. If the cavern is generated low enough, it will replace bedrock. This would be easy to fix - just have the terrain generator make a final pass, turning everything at layer 0 into bedrock if it isn't already. But maybe getting to see/fall into the Void could be a reward for finding one of these caverns, choosing to get rid of the lava for some reason, and discovering that the final layer can be mined through.

I was playing vanilla survival mode, and I built a 3x3 quarry. I went to the bottom and there was diamond and Bedrock. Now I gathered the diamond an wet hme. I came back with a diamond pick and started mining for more diamond. I thought "Hey, Let's see how strong bedrock is." And I started mining it. About 5 seconds after I started, there was a hole. I looked in my inventory and saw 1 bedrock. I'm going to find that world, and I'll put the link to download it in this talk --68.98.58.195 14:34, 6 March 2012 (UTC)255jimbo


 * How about you give a version number, seed, and coordinates? A world download would, at most, only prove that you know how to use a map/inventory editor. 「 ディノ 奴 千？！ 」? · ☎ Dinoguy1000 17:43, 6 March 2012 (UTC)

Removed A Line
Hello, just saying that I'm not a vandal and that edit was meaningful. Removed the line saying that ore can be encased in bedrock. Unnecessary to know, nobody in survival mode can use this knowledge because they won't be able to get to the ore anyway. This was my summary: Unnecessary line. How would this knowledge benefit somebody if an ore was encased in bedrock? You can't find out anyway if you're playing in Survival, so no need to try to look. Uninteresting tidbit of unnecessary knowledge. 98.116.230.185 00:53, 28 June 2012 (UTC) Dakilven

I reordered the page
Hey, I reordered the article to remove the confusion between classic and current bedrock. I did this after my friend told me "bedrock is impossible to place down in current multiplayer without mods" after he told me that it was read off the wiki, I decided to change it. Also, there's actually a few comments in this talk page about "/solid" being incorrect. 38.99.130.61 13:34, 18 July 2012 (UTC)
