! Minecraft used to work on WinXP 32bit with ~3,4 GB usable RAM until beta 1.7.3 even with "Far" video settings. I just got the famous missing chunks, which did NOT appear with "Normal" settings. After beta 1.8 with "Far", the jawaw.exe (the JavaVM) running Minecraft eats up memory over time (several minutes, faster when flying around) until hitting approximately 1 GB RAM, then Minecraft begins to lag heavily with freeze times from few seconds up to minutes, but without any major CPU usage. The spawn on an anarchic server even forced me to set video to "Short", because of freezing. F3 doesn't show any evidence of such a memory consumption. Allocating more memory is no use, because starting Minecraft fails if set over 1300MB and this does nothing to the freezing, which then starts even earlier, at 900MB RAM consumption. When set to "Normal", the JavaVM with Minecraft uses between 600-1000 MB. While there is a warning for the "Far" setting, there has to be a bug, because this is an unidentified RAM usage. If this bug is not in the game system, at least the debug screen has to be corrected. (CAPTCHA system seems broken for me and doesn't let me post links) Screenshot: h__p://i.imgur.com/lFgpq.png --78.35.138.237 03:29, 2 August 2012 (UTC)
 * The 32-bit Java VM cannot give Minecraft enough memory over time in "Far" mode, and you've perfectly described the result: The game runs out of memory, gets laggy, and ultimately freezes or crashes. Don't use Far mode on 32-bit systems like the warning says--problem solved.  Running out of memory isn't a bug unless there's a memory leak, which isn't indicated.  The Java VM and the libraries Minecraft use require memory above and beyond what Minecraft is using internally.  ---Jovet 09:38, 2 August 2012 (UTC)
 * After the third such crash (before finally seeing that I had Far on), and running with Shift-F3, I managed to catch some numbers: Used memory was 406MB/512MB and Allocated memory was 512MB/989MB on the frame that the game crashed. Still, this is nothing compared to the problems I had with Optifine 1.2.5!! -- Featherwinglove 05:09, 5 August 2012 (UTC)

Must note that issue is not new, occurred during 1.9 pre release before being fixed but has now returned for 1.3.1, decided to report as normal CPU usage is approximately 70%.

 * Dual core - - no BS, be polite Darkinnit 09:40, 2 August 2012 (UTC)
 * A unmodded Minecraft before 1.3 is single threaded. One thread handles everything: block update, entity update, chunk (un-)loading as well as rendering. With the 1.3 update, Minecraft is now dual threaded. One thread simulates the game: that's the internal server. And another thread renders the game: that's the client. This is roughly how Mojang merged the SSP and SMP. For details see Dinnerbone's forum post: www.minecraftforum.net/topic/1342074-how-do-we-feel-about-13/page__st__40#entry16392586  So, after all, it is normal that your CPU usage is above 140%. If your Mac is overheating, it's most probably not Minecaft's fault. --130.83.20.209 04:45, 4 August 2012 (UTC)


 * Thanks for that explanation, I was aware of the change but did not expect it to take affect so dramatically. I'm still of the opinion that it was not intended for CPU usage to be this high. I run plenty of multithreaded high demand programs on my mac using muc less CPU, a constant precentage in this range is nuts really. Another point I want to take up is that when using the optifine mod with previous releases, enabling the 'Smooth FPS' option in settings greatly reduced my CPU usage when playing the game. If any devs read that perhaps that can help.

Annoyances a mp When using an automated piston system to push arrows off of the face of an arrow detector, there is fairly high chance of causing a glitch that causes all pressure plates within an area measuring 21x21x21 blocks to stay active once they've been activated. This glitch remains in effect until the area has been unloaded from memory. Video: http://www.youtube.com/watch?v=tsyz5Kh5Qfo

!sp The spawn location for players when they start a new map or die on a map is randomized, and as a result on certain maps... especially "survival island" maps, are rendered useless due to this change in behavior from 1.2.5. The problem is especially rampant on something like a SkyBlock type map (or a variant) where if the whole area near the spawn location out to +/- 10 meters is not safe to spawn in (it usually isn't on these kind of maps) that there is a strong possibility of simply rendering the map unplayable as you keep respawning over and over again in the dangerous areas. I've tracked where this "fuzz" is being added to a specific section of code in the "EntityPlayerMP" class constructor (via MCP):

The problem with this particular section of code is that it presumes wrongly that every location near the spawn is safe to spawn into. This does render a certain class of user-created maps as either useless or sort of turns them into a kind of "hardcore" mode as those maps are unrecoverable upon death. Even changing the spawn point doesn't help as this function explicitly moves that location about a bit in a random fashion. I understand the problem it was trying to solve, as on multi-player servers with hundreds of players it sometimes can get annoying to have everybody spawn at precisely the same point on a server. For single player situations (or for small groups of players) that isn't nearly so big of a deal. This is a cheap fix to a serious problem that IMHO needs a better solution as it has unintended consequences. --Robert Horning 12:49, 4 August 2012 (UTC)


 * Hold on a second. Is this accurate:


 * Is this really setting Y based on X and Z, and then altering Z? If Y is based on the terrain at X/Z, then Y needs to be set LAST, not in the middle.

--Keybounce 20:04, 4 August 2012 (UTC)
 * p.s. Please have a code review. If that got through, who knows what else needs a check.


 * Yup, this is right out of the source code currently running MC 1.3.1. I see the other bug you are alluding to here.  I guess we are the code review team on this one.  BTW, as a "fix" here, I would suggest that the following ought to be the code change instead:


 * The point of the "spawn fuzz" would be to have something settable in the server parameters so server operators can define the spawn radius for their players, making it at large or as small as they need. By default this could remain 10 meters from the formal origin point when using the vanilla server, and for the "single player" users could be simply set to 0.  It is always nice to have custom settings that are user defined, isn't it?  --Robert Horning 20:28, 4 August 2012 (UTC)

undefined sp During a LAN game, I was blown up by a Creeper and chose not to respawn right away, but after respawn to my bed (some 25-ish blocks away), then traveling to my remains (which my partner had collected my things after respawn), I noticed a Creeper entity, some block (item) entities, and a couple explosion entities in this pit the explosion created. It resembled much of what the explosion entities used to do before they were patched in earlier versions. I just restarted the game and opened to LAN again.
 * Further info: we each have super video cards in our comps and none to extreme minimal lag. Aerotactics 00:29, 5 August 2012 (UTC)

! When pillaring with sand/gravel, as you break blocks below, the player will occasionally be moved to one side and fall from the pillar. This occurs even if one block is broken at a time, with a pause between breaking blocks. Avatar6969 3 August 2012

undefined When entering or exiting the end, the experience and your levels appear to be set to null, relogging or recieving more experience updates it and fixes this. (Annoying when hosting a LAN server as the server shuts down upon relog). Bondenn 23:15, 2 August 2012 (UTC)

! sp When playing in singleplayer, I am in creative with cheats on, and I did a lot of building, then since my Windows computer crashes a lot, I saved and quit to title. When I rejoined my world, nothing was saved. I angrily tried building again, thinking it was just a one time thing, later I found out, it was not saving anything I did. I don't know if this is because of the new trial version you have, but I have a full account. I do not run any mods. I am not sure which category this is in, but I know that it is a major bug. I don't know if other people are getting it, but it happens to me every time that I play.
 * This also happens to me, although I play in singleplayer survival.

! sp When playing in single player, I am in survival with cheats off, and the game world consistently refuses to save. The first time, I dug underground to wait out the night, saved & quit in the middle of the night, and when I logged back in, the blocks were back, and I suffocated. The second time, I had just finished smelting some gold ore and put it in my inventory before I logged out, and when I came back, I had the ingots in my inventory but the gold ore was being smelted in the furnace. Third time, I'd returned to my base and put a full stack of iron and a quarter stack of gold in a chest. The next time I logged in, the iron and gold were both missing.
 * This happens to me as well, I really would like to see it fixed. Playing the game is pointless if you cannot save!
 * That's not "refusing to save", it's a buggy save. On the other hand, I've also had items go missing between chests, without saving in between.  Nothing more important than a stack of wood, but it's worrying. --Mental Mouse 02:12, 4 August 2012 (UTC)

! sp Sometimes, when using the /kill command in 1.3.1, you spawn in a place where there are at-least 3 chunks which are not loaded (chunk error/world hole) . Note, this is on SINGLEPLAYER, and the chunks will never load. I haven't tested this bug several times, but it could lead to a crash. I do have a screen capture though, and I'll post it on my deviantART(substitute541)

undefined ? Impossible to have an enchantment between level 20 to level 30 even when 18 bookshelf is around it.--Stubcow 18:38, 2 August 2012 (UTC)
 * might just be bad luck but I've try for at least a good hour and non of the enchantment option are between level 20 and 30.
 * Try reducing the number of bookshelves? Or are you talking only in cases where you have maxed out the bottom entry for enchantments, the second one won't show 20-30 enchantments? If so, this is more of an annoyance. --Moleculor (talk) 21:01, 2 August 2012 (UTC)

!Far away chunks don't update, and chunks aren't always loaded properly. You can see this glitch by using tnt. In a superflat world, create a long path of TNT. Ignite the tnt at the end of the path. wait in the same spot until all of the tnt has exploded. follor the craters from the tnt, and you will notice that it looks like some of the tnt hasn't exploded, even though it did. if you exit the world then enter it again, the world will properly update, and you will see the craters where the tnt that didn't look like it exploded was.
 * This appears to be related to 1.3.1pre bug reports related to long redstone wires. link -- Featherwinglove 15:34, 2 August 2012 (UTC)
 * Confirmed.

! With Single/Multi-Player Mode Merged, Spawning now works like it does in Multi-Player for Single Player maps. This breaks the Spawn points in my maps, and it will break the spawn points in any other user made map, unless they set the player spawn with a bed (not always possible - depending on the map type) or start the player in a 20x20 room. It would be nice to have a way to control the spawn point, maybe in creative, for map makers. --Brandonn --184.76.94.151 04:40, 2 August 2012 (UTC)
 * Are you sure this should be a major bug? It seems more like an annoyance to me. In any case, you can set the spawn points with MCEdit. --Jorr 18:23, 2 August 2012 (UTC)
 * It should be pointed out this even impacts spawn points set with MCEdit, as it breaks where players are actually spawned. I apologize as a bug I reported was a duplicate of this one... I just found where the bug was actually located in code.  --Robert Horning 20:41, 4 August 2012 (UTC)
 * Being unable to control spawn point in vanilla MC is a serious flaw. Just imagine (my actual world) where the spawn area is in extreme hills, so you can be in two very separate areas based on which RNG roll you get. --Keybounce 05:07, 3 August 2012 (UTC)

! If the host for a LAN world changes (e. g., they were siblings), the new host will get the original host's items, and if the player who connects to the server is the host, they will get the items, exp, armor, etc. that the host has at the state it was published. I believe that if another player then joins the server, then they will get the same items and worn stuff as who last hosted the world. If the original host were to host again, they would have the last host's stuff. It is like they they have never player before, for they haven't, as a connected player. If a third player were to connect both times, it may keep his/her items, but I have not tested it. This issue reoccurs every time the host changes. I believe that this bug has something to do with a feature retaining to the items a player has on hand when leaving a world, and that ANY player can log into that world and have the items present at hand. And since the world must be opened to LAN, it is initially logged in as singleplayer, and so that event takes place. If a player who had connected to the world then hosted the world, their data would be lost. A protection or two must be placed, possibly toggleable, in order to resolve this. If offline, they must not be able to play on a LAN network, but should still have a separate profile than the rest. --Wormy14 13:02, 2 August 2012 (UTC)

In an earlier snapshot of 1.3, this issue did not a occur. On a related note multiple people in a household could share a world with their own characters (not playing LAN, but using same shared world with different usernames.) This is no longer possible due to the above described problem. -- Izzik 4 August 2012

! Travelling between the Nether and the Overworld still regularly causes you to fall into the void and die, probably because of non loaded chunks. -- Tiax 13:50, 1 August 2012 (UTC)
 * Absolutely confirmed, no matter how many downvotes on Reddit I get for saying so. *Just* had it happen to me. It's gotten so bad that I've downloaded NBTEdit to teleport my player back to a sane location when it happens. Moleculor 00:53, 2 August 2012 (UTC)
 * For now, you can use a work-around by disconnecting and reconnecting BEFORE going through any portal. If it still happens, quickly dis/reconnect again and you should be on solid ground. 02:49 2 August 2012 (UTC)
 * Happens for me every single time I teleport back to the Overworld with my old world. After it happened in this direction I won't be able to teleport to the Nether either. Will do more testing with different/old/manipulated world files. -- Zuckel 08:25, 2 August 2012 (CET)
 * Happens for us with a portal sitting on 0,0 - every time going to the nether and most times coming from the nether. Another portal nearby has similar issues, but other portals in the world seem fine. Breaking and recreating the 0,0 portal does not resolve the issue. Could it be a divide by 0 error somewhere? 0,0 is not our spawn location if that makes any difference. Darkinnit 09:47, 2 August 2012 (UTC)
 * If this happens to you, you can also try to quickly switch to Creative mode and fly up and out of the danger zone of the void before you die. Then quit the world and re-enter, and it should then load okay.  You can then revert Creative mode.  Backing-up the player/level data file before traveling is also a good idea just in case. ---Jovet 09:55, 2 August 2012 (UTC)
 * When I jump back from the nether in survival mode, I come back to nothing, no terrain, mobs,etc. If I save then relaunch the game, things are fine. 17:25, 2nd August 2012.
 * I had this happen after I died falling off a flinting pillar, no Nether Portal involved (I hadn't built it yet.) Both my bed and original spawn (probably in neighbouring chunks) were in cache range.  I fell through twice before spawning on solid ground.  I haven't had this happen with a portal transit yet. -- Featherwinglove 18:27, 2 August 2012 (UTC)
 * This happens to me almost every time I go through my nether portal, on a remote server. This changes everything - you simply can't have anything valuable on you when crossing worlds, because you will lose it in short order. This bug breaks the game. Thue 10:24, 3 August 2012 (UTC)
 * This occurs when I go through the portal to the nether near the spawn point on my SMP server. It never occurs the first time I go through, but it occurs every subsequent time until I disconnect and reconnect. There is another nether portal 100ish nether blocks away that I haven't had it happen on yet, no matter what. Seems to be related to particular chunks. --Zair99 13:53, 3 August 2012 (UTC)
 * Demo video. Thue 17:51, 3 August 2012 (UTC)
 * I've tried around now and I can confirm Zair99's finds. My testing also showed that it doesn't happen when another player watches me come out of the portal, i.e. the chunk I port to is already loaded. Further, the "first time works" counter seems to be player specific. Trying with 2 players simultaneously, one could go through without problems and the other not, depending on which one had already ported before. Even further, the problem won't occur in case the world you port to is just now generated by that port. Experiencing the issue on any portal in my old world that I started with MC 1.0. Less often on fresh worlds. -- Zuckel 3.8.2012 20:47 CET

undefined When being pushed into a corner by water, you take suffocation damage.
 * I don't think it's suffocation damage. In fact, if you're under water while it happens you have air bubbles but they're full, and they don't go down. I stayed in the water until I died (which took about 10 seconds) and I died with 10 full air bubbles. --5thHorseman 19:00, 4 August 2012 (UTC)

undefined Also, even on normal mode, zombies can in fact break down village doors (observed). On consideration, I'm pretty sure this is why I've had two villages depopulated on me, in 1.2.5 and 1.3 (villager spawning presumably isn't fast enough to replace the losses). (An alternative explanation would be buggy pathfinding... that is, accumulating damage from excessive drops.) No sign of iron golems, perhaps the villages aren't big enough. --Mental Mouse 03:41, 3 August 2012 (UTC)
 * "Normal mode" as in not hardcore mode, or as in normal difficulty? Looking at the code, it seems clear that doors should only be broken on hard difficulty. -- Orthotope 04:34, 3 August 2012 (UTC)
 * That's "normal difficulty", survival mode. One thought is that the doors may be wrong-way-round:  The originally generated doors appear inset into their wall (that is, the inner side of their block).  When I place a new door from outside, it appears flush with the wall. --Mental Mouse 12:03, 3 August 2012 (UTC)

undefined On the Mac, it is possible to map sneak to caps lock. However, as soon as any menu comes up, any chest opened, etc, the sneak turns off, while caps lock stays on. On return to the game, caps lock is still on, but sneak is off.

In other words, when the key for sneak is pressed, sneak activates; when a menu/inventory/chest opens, sneak deactivates regardless of key state, and won't be reactivated until a new key_down event occurs, which in turn requires a key_up. The game gets out of sync with the physical state of the keyboard. --Keybounce 05:07, 3 August 2012 (UTC)

I also experience this on windows 7, but always assumed it was intended. the caps lock button acts like any other, and the caps lock light does not change sneak in any form(nor should it). menu's cancelling sneak on the other hand is a separate issue, and one I think shouldn't be fixed, it introduces risk for players sneaking around someones base, and prevents them from crafting and sneaking at the same time which is good from a gameplay point of view. --101.166.17.204 06:12, 3 August 2012 (UTC)

undefined Fishing: Compared to 1.2.5 single player:
 * It is harder to fish, in general:
 * Situations where I could fish in one deep water in 1.2.5 now fail; the bobber consistently gets stuck on the bottom.
 * The bobber seems to want to go farther out now
 * Fishing in a small area (3 land spaces, then 4 water spaces, with the water 1 deep) was easy in 1.2.5 single player, reasonable in 1.2.5 multiplayer, and painful/not doable now.
 * Fishing in 1 deep, 2x2 pond, by standing directly over the water and dropping the bobber down would result in the bobber floating in 1.2.5, and ground-stuck in 1.3.1 (Yes, I have that 1.2.5 on video -- link in a few days)
 * 1.3.1 multiplayer is giving me lots of false sounds and bobber movement, compared to 1.2.5 single player. In fairness, 1.2.5 multiplayer took me a while to learn how to fish, so it may be a similar issue of retraining.

! Client/server inconsistencies. I have had a couple of experiences with phantom damage, which I attribute to the client and server (SMP) disagreeing on my location. First, I was swimming across a small area of water towards a boat. When I reached it, I was in 1-deep water, but I couldn't interact with the boat. Suddenly, I started taking damage. I re-logged and found myself at the bottom of the lake, drowning, several blocks short of where the boat was. The second experience: I threw an enderpearl towards the top of a desert temple, and it hit the roof. I dropped down but immediately started taking damage. Again I could not interact with the world. Upon relogging, I reappeared briefly suffocating inside a block at roof level, and then dropped down a second time. Itsmartin 20:09, 3 August 2012 (UTC)

a! Villager trading is still very much imbalanced. Non-farmables are undervalued, e.g. 4-5 diamond must be sold for a single emerald. Meanwhile, farmable items are overvalued, e.g. 19-29 paper for an emerald. With a sufficiently large sugarcane farm, I have been able to earn around 7.44 stacks of emerald in an hour, and while this is not in and of itself bad, these emeralds can be spent of many diamond items. The net result is a far bigger earning from farming than the most efficient mining practices, even with Fortune III. In fact, just one harvesting of the farm nets a player several doublechests of diamond items, which is very overpowered. In addition, many prices are nonsensical, e.g. iron and gold are considered equal in value, and mundane items such as compasses are considered more valuable than diamond tools. Server administrators are considering disabling trading and villagers on their servers because of the current imbalance, so this is a major annoyance. --WolfieMario 21:27, 30 July 2012 (UTC)

a! Falling in to the void kills you. Why? The player (in Survival) should never be able to reach there by normal means, so most, if not all times they end up in the void is due to a bug.

? Iron Ore does not yield experience when mined.
 * Iron ore isn't suppose to give exp. If it did, a player could keep breaking it, placing it, and rebreaking it to get a lot of exp.
 * If each block had a bit that could indicate whether a block is an originally-generated block or not, then that bit could indicate whether Experience points are deserved (i.e. the initial breaking). Every block the player changes by placing a new block can have its bit set to indicate it isn't original with the generator. ---Jovet 09:53, 2 August 2012 (UTC)

 * afaik lava and fire can ignite in a 3x8x3 area starting 1 below them. while this makes sence since irl things start to burn because they reach a certain temperature rather than having flames next to them (flame are ofc a heat source but if they weren't they wouldn't ignite anything). the only "flaw" in the minecraft system is that non flamable blocks can't act as "heatshield" but then even the best uncooled heatshield will let the heat through once it has been heated enough. Since realistic temperature probably won't make it into the game the solutions would be either leave it as it is and adapt the building style (blocks won't start to burn if there isn't an air block next to them in the "ignition area") or make blocks with a full hitbox from below block the ignition area for the above part of that air column it is in (which probably will cause more server load) 9.33.122.76 15:18, 4 August 2012 (UTC)

Bugs

! Major bug with pistons that breaks many designs. In certain configurations, the pistons will "stick" into a form where they are both extended and retracted at the same time. The only way to reset them is to break the piston and replace it. This is easily reproduced in a design such as this: i50.tinypic.com/mm4i7q.png. As you can see, the top row of pistons are both extended and retracted at the same time. If you build this design and power the pistons while the reeds are grown, they will stick every time. Still experimenting but it has something to do with pistons pushing two blocks/items across from each other, or something related.

! Signs often don't load properly and appear blank (only tested on SMP). When logging into a multiplayer server where there are signs over a large area, only the signs in the same chunk that the player has logged in at load correctly. Any signs that are further away do not load correctly and will appear blank 99% of the time. If the player logs out in a different chunk and logs back in again, the signs will load for that chunk, and the previously loaded signs in the other chunk will unload again. --Userof2 14:18, 1 August 2012 (UTC)

! Pistons no longer reliably push entities. This breaks many elevator designs; see this video for several examples.

Repeater (4) Input signal (set) (redstone wire branch to button) Repeater (4) Inverter (torch) Input signal (reset) (redstone wire branch to switch) Repeater (4) Inverter (torch)

Loop timing: 14 redstone-ticks If the switch is "on/down", then the button cannot put a clock signal into the loop. If the switch is "off/up", then the button can put a 9 redstone-tick pulse into the circuit, and it will then act as a clock.

In 125 single player, it works perfectly. In 125 multiplayer AND 12w27a, and 131 release, it will lose its timing. Approximately 15 16 tests; 14 go to lockup (the button side of the rs-nor being on all the time), and one two to inaccurate stable timing (on pulse is less than 9 redstone ticks; off pulse is longer than 5.)

Annoyances

a Mushroom blocks can't be harvested or placed properly, reverting to damage/data value 0, a block which appears to use the mushroom pore texture on all six sides. This makes it impossible to use the red, brown, and white mushroom block textures in creations without using pistons to push blocks around. It is also inconsistent with the expected behavior of silk touch: if silk touch is capable of harvesting a block, it should not transform it upon harvesting. Transforming a block upon its placement (which happens when placing mushroom blocks of any damage value, obtained through cheats available in vanilla) is also completely illogical and a roadblock to making things from the mushroom blocks. Perhaps mushroom blocks could be made properly harvestable as "Red/Brown Mushroom Top", "Red/Brown Mushroom Edge", "Red/Brown Mushroom Corner", and "Red/Brown Mushroom Stem", where the edge and corner blocks would be placed in a directional manner similar to pumpkins (upside-down mushroom blocks would not be available, as this would require splitting the current two mushroom block data values into multiple). --WolfieMario 13:44, 12 July 2012 (UTC)

undefined The map item becomes increasingly unusable as more exist in a world. There are no issues for a map with a low number, such as map_0. However, around map_50 issues start occurring, and these issues seem guaranteed at around map_100. Maps higher than 150 tend to be entirely useless. The issue in question? The client fails to display the correct map, instead displaying an arbitrary number and blank map. This number will increment when the player drops and picks it back up, or attempts to use a crafting table or other form of GUI except the inventory. Once the map has hit the correct number, it may be used, but the client fails to properly display any regions which have already been mapped. At low map numbers, this manifests as vertical streaks across mapped areas. At around 150 or so, these areas are simply blank, and will only display content which has appeared since the last time the map was viewed. When new areas are mapped, or existing areas are updated, only the changed pixels will display to the client; all else will remain blank. On large servers, this makes the map item essentially unusable: once a map is 100% complete, it will only display as a blank map to players. This issue has been present on servers for a long time, although I personally have usually only experienced maps where half of the vertical columns of pixels failed to load; as a server I play on has 150+ maps now, they have become utterly unusable blank rectangles. The issue is now present in singleplayer as well. --WolfieMario 01:47, 4 August 2012 (UTC)

However, this is predictive, and the client does not actually check with the server. In some cases, the server leaves the item down below, and you have to dig a hole one space down to pick up the item. The bug here is the client thinking it knows something, and presenting it as fact, without attempting to verify or correct what it shows. --Keybounce 06:12, 3 August 2012 (UTC)

Bugs

!mpTamed Wolves/Dogs: If a player attacks you, and you have tamed wolves, they become aggroed towards that player. They won't stop attacking said player until that player is slain. If the player logs off or is killed, the dogs still growl but otherwise behave like they are not aggroed. However, if they are left sitting down and the player walks away, they despawn as if they were a hostile mob. This is likely because the game thinks they are hostile untamed wolves. Below are a few different solutions I thought of.
 * Add an exception to the despawning rule for dogs
 * Make dogs not attack other players
 * Add a timeout so dogs stop targeting something if they don't get a hit within x number of seconds
 * Make a loop that runs every 5 minutes or so to check if a dog is aggroed, clear target it if is

a World generation and switching worlds When generating a new map, or switching from one world save to another, a lot of invisible underground structures and terrain are incorrectly rendered visible, instead of the surface terrain which should be rendered visible, in chunks near the player, this is really annoying and there exists that the possibility that inexperienced players could die due to fall damage from invisible surface terrain they fall onto due to the surface terrain in chunks next to the player not rendering at all in extreme instances. A temporary workaround is to exit and restart Minecraft every time you generate a new map or switch from one to another to limit this error, however, it is still possible that in some instances surface terrain will still not render properly resulting in chunks incorrectly rendering underground structures.

Sounds
Bugs

!When Minecraft is started, somehow the sound doesn't play at all for quite a time or the one or another restart, then somwhen just works again and stays this way (Vanilla 1.3.1, Ivy Bridge, Win7 Ultimate SP1 x64, current drivers, Realtek ALC887 HD, JRE 7.0.5 x86 & x64, LWJGL 2.8.4, Sound 100%, Music %). Looked like the system is causing it, but now it's verified on two other machines also. First thought of mute but everything else is playing; this is unique to Minecraft. Maybe a problem with the LWJGL update? This, however, just happens the very first time when Minecraft ist started after a System start (?) and stays away once it fixed itself until the next time it occurs.

! - There is still an issue with missing pickup sounds, missing sounds for breaking certain blocks and missing footstep sounds on certain surfaces using OSX Mountain Lion. It is possible to fix the sounds by updating LWJGL (2.8.4) but doing so causes visual problems (rapid spinning when entering fullscreen and just perceptible flickering). This means either having to play the game without sound or not play at all because the flickering effects causes headaches. --Tseotet 19:37, 1 August 2012 (UTC)


 * Confirmed. I was wondering why it was so quiet. I didn't realize it started after I installed Mountain Lion. I did not try updating LWJGL so I can't confirm the visual problems 132.203.168.221 04:51, 2 August 2012 (UTC)

 * I can confirm this too. We are getting the same on our server and sometimes sounds are delayed by over 1 second with the "backlog" of sounds (eg. from a line of placed blocks) suddenly arriving in a bunch.  The actual block placement is happening in real time and no issues there, it's just the sound delay.  Our server location is in the next city and we experienced no such issues in 1.2.5 so it's clearly a bug with 1.3 and nothing to do with "servers with a slightly less than great connection". --Rik1301 23:07, 2 August 2012 (UTC)


 * This seems to only happen on SMP servers with a slightly less than great connection. I can't find it on Single player, nor does it happen on the rented server hosted withing the same state as me. It's almost as if the server is controlling the few sounds, block placing, footsteps and eating. Breaking, punching animals all have the timely sound response.

undefined Not so sure if this is an issue with my computer or minecraft but when I enter or exit the nether or the end the sound that is supposed to play on entering the loading screen before you arrive in the other dimension does not play. Also another issue related to this is that when on the same screen instead of the text reading Entering The Nether/End it reads Downloading Terrain. -- McLaren_231 (MC username) 16:35, 3 August 2012 (UTC)

Annoyances a -client doesn't download sounds until a few minutes after update is installed leaving people who fresh install without sound. Additionally after sound files are downloaded the client may still take a few minutes or completely fail to initiate sound.

a Sound volume controls only exist for "music" and "everything else". There is no way, for example, to turn down farm animals and rain, while keeping important stuff (mobs walking towards you, note blocks, hostile mobs making noises, etc) loud. --Keybounce 06:43, 3 August 2012 (UTC)

a The behaviour of the new reordering feature (shift-arrow) in the MP Serverlist is illogical: A changed position of a server in the list is saved only on editing and saving ("Done") any server entry. (Also editing one that has not been moved will save the position of the moved one.) The change is discarded when you cancel the editing of any server entry instead, it is discarded also on refreshing and cancelling the list (may be intentional here) but it is also discarded on a server join which will the the most likely action after reordering.

undefined The F3 display of lighting info -- bl / sl / rl -- does not give useful data. At night, outside, it will show bl 0, sl 15, rl 15. Near as I can tell, bl is "burn light" -- how much light you are getting from torches, sl is sky light -- how much light you are getting from the sky, and rl is the higher of those two.

[b]EXCEPT[/b]: It's not the game's light level: it's the graphic engine's light index. The moon has light level 4, but still has 15 levels of display lighting (and I can detect about 10 on my computer display).

Result: When the actual game light level is 4, I see numbers of 0 (no torch), 15 (maximum sky), 15 (meaningless result number), and this corresponds to the graphic engine using a 0,15 index into a moonlight table.

Note that this makes RL useless. Torch + sky, for example, will show the same RL as sky alone, yet torch+sky has a much brighter display (And the same game brightness).

In fact, this may point to a flaw in the game's lighting assumption/mob spawning system. The same display brightness given off by a torch (only) at light level 8 might match the display brightness given off by torch+sky at torch 6, sky 6, yet with the same visual lighting you now get mobs.

undefined Cheats default to "off" in survival worlds created in 1.2.5 or before. This also seems to apply to pre-1.3.1 worlds downloaded and installed that were set to Survival. This is at least an annoyance because I cannot shift even a copy of those worlds to Creative, and quite possibly a bug because Survival Cheat worlds can be created manually in this update. Suggested fix: When first loading a new world in 1.3.1, give the option once of "Enable Cheats? Yes/No".

Work-around: Learn other timestamps. Annoying. Use a pair of /time sets, one for 23000, and then another for 0 to start the game.

undefined In Czech: - Iron sword should be called "Železný meč". - Jungle tree and all its products (saplings, leaves, logs, planks, stairs and slabs) are named incorrectly. The tree is called Sekvoj (= redwood tree) which is nonsence because redwood trees are conifers unlike Minecraft jungle trees which are broadleaf trees. I suggest calling it "Tropický strom" (= tropical tree). Tropical tree sapling = "Sazenice tropického stromu", Tropical tree leaves = "Listí tropického stromu", Tropical wood = "Tropické dřevo", Tropical wood planks = "Prkna z tropického dřeva", Tropical wood stairs = "Schody z tropického dřeva", Tropical wood slab = "Půlblok z tropického dřeva". - Flint should be called "Pazourek". - Blaze rod should be called "Ohnivá tyč". - Jukebox is commonly used expression in Czech and shouldn't be translated.

undefined IME support is (still) missing -- as noted by others previously, too. I think the developers should start to examine this problem, because 1.3 release is a major milestone in terms of software engineering.

I found that the latest version of LWJGL (2.8.4) can handle IME to some extent. I could type Korean characters on Windows, with the following limitations:
 * The completion of a character must be committed explicitly by pressing the space bar twice or using an arrow key, whenever I try to insert a space between words or to press enter to finish typing. This is very annoying for Korean users. (Not sure for Japanese/Chinese users...)
 * I'm not sure this should be fixed by Minecraft or LWJGL, though.
 * Even this flawed typing is only supported at chatting & item search box in the creative mode. Not at all possible with signs & book and quills. The latters do not seem to use any generic text input UI elements.
 * The IME state is not changed after finishing typing, and thus the in-game keys such as A, W, S, D, I do not work. They are delievered as Korean characters to the game even when the user is not using a text box. I had to change the IME state manually to the English typing mode.

On Mac, the character is not properly composed and only the first-typed consonant is actually given to the text box. I have not tested on Linux since I always play Minecraft on Windows or Mac.

I know this issue is hard to inspect for Western developers since most of them may have no experience on character composition systems used by many East-Asian languages. I think http://en.wikipedia.org/wiki/Hangul and http://en.wikipedia.org/wiki/Korean_language_and_computers would help you to understand. Major operating systems such as Windows/Mac have their own IME(input method editor) API and contains a default IME implementation for all supported languages. Linux has a wide variety of 3rd party IME applications for GNOME/KDE GUI environments.

Technically, all text inputs must be implemented to use operating system-provided IME APIs, instead of manually appending individual characters to the value of the text field on key-press events.

So I suggest the followings:
 * Update the LWJGL library distributed with Minecraft to its latest version.
 * This should enable the limited possibility to type East Asian languages at least.
 * Since Minecraft is one of the most popular games implemented on top of LWJGL, I or you guys could request the IME issue as a major consideration for their next releases.
 * Use a generic text GUI element for every text inputs, including signs & book and quills.
 * Disable IME when no textbox has focus, to prevent unintended translation of keys for the gameplay (e.g., A/W/S/D/...) by IME.
 * This is a common operation in Korean GUI applications: the IME is disabled for the password input fields, which may confuse the users by allowing Hangul passwords and denial of service due to differences of IME settings in PC to PC, for example. All Korean PC games automatically turn on/off the IME depending on the context.
 * Expose a modding API that enables customization of text inputs.
 * It should feature a live display update callback like Windows IME API to show intermediate composition process to the user, aka "on-the-spot" IME.
