Due to the change in the world generation method, I went and found a map seed that was suitable for using  to paste our old structures into it.  The only problem is, there is a region around spawn (which I moved a ways from the original staring position using the editor) that is completely uneditable.   Blocks can neither be mined nor placed Doors don't function properly (door splits between the top half and lower half, changes randomly when interacted)  Chests won't open.   Immediately outside that area, though, everything behaves fine.  I don't know if the behavior is limited to a particular chunk or not.  Could deleting something like session.lock work?  Maybe a file permissions issue?  Currently no one is using the server yet and have a backup of the world, so I should be able to fiddle with it with no risk.  Other info:   Minecraft 1.0.0 Vanilla server (no mods)   Any ideas?

The Minecraft forums seem to be filled with threads regarding a "block respawn" bug. I set up a 1.3 SMP server on my LAN, and notice this as well. All blocks respawn a couple of seconds after being destroyed, and non-local players lag tremendously.  It makes the game unplayable. Has Notch commented this issue? Is there a solution that makes the game worth buying?

So I have been working on my Minecraft world for like a year. I can play and save my world without any problems, but when I look in the saves folder, my world is the only one not in there. I need the file is so I can reset my computer without losing my Minecraft level. Where is my world even saving to?  Please help.

So on my multiplayer server on Minecraft Education Edition I can't seem to figure out how to make the blocks in spawn unbreakable. I know adventure mode fixes that but it's a survival world. I don't want them in adventure, so how do I make the blocks in spawn unbreakable?

Please don't mark this as a duplicate of my previous question which was asked anonymously. this is a reattempt because i cannot edit the first attempt.  What I have so far is:  - randomly generated tile set with items on SOME tiles - one creature spawner that spawns up to 5 creatures which can be controlled by the player - the ability for creatures to pick up items and bring them back to the spawn and store them for later use  What I am noticing is when i launch the game, it doesnt always show all the sprites. Sometimes the spawner is missing, or the creatures, or the GUI. ANd when things DO appear, if i tell the creatures to pick up anything, other items on the ground randomly appear and disappear. even the spawn sometimes disappears! what I do notice is that when i have multiple creatures, some will disappear when crossing invisible lines but not all of them. i forced two creatures to go east at the same speed and time, and one vanished and the other didnt.  If you have any ideas as to what might be causing this, please let me know. if you have any questions, i'll try to edit to appease you.  thanks for reading!  I have my draw method like this:  GraphicsDevice.Clear(Color.CornflowerBlue);  // TODO: Add your drawing code here  spriteBatch.Begin(SpriteSortMode.BackToFront,           null, null, null, null, null,           camera.GetTransformation());            worldEntity.Draw(spriteBatch);  guiManager.DrawGUI(spriteBatch);  spriteBatch.End();  base.Draw(gameTime);   for the world entity...  its draw method systematically goes through each tile in the world and calls its draw method. the tile draws itself using  Vector2 topLeftOfSprite = new Vector2(this.X, this.Y); Color tintColor = Color.White; spriteBatch.Draw(tileTexture, topLeftOfSprite, tintColor);   and then proceeds to call the draw method of any items on it.  creatures and items have very similar draw methods.  the gui also draws itself in a similar fashion.  what i DO notice is that ive NEVER seen ground tiles vanish, only the items on them or creatures in the world. Could it be their Z isn't set appropriately?

I'm making a game where things randomly generate. It used to work, but now all the sudden they keep spawning in the same area every time. does anybody know a fix?

I am trying to make Minecraft harder, and one of the ways I wish to do this is to have a "pseudo-hardcore" mode where dying spawns you in a random location rather than completely locking you out of the world.  I intend to do this by setting the spawn radius to be very high.  However, I also want to make this "bed-proof" - that is, if someone places a bed and sleeps in it, I want the player to still be spawned in a random location, regardless of their personal spawn point.  How do I do this? Command blocks are fine, but data packs are not preferred.

Ok, so for the last few worlds I have created, I did a bit of exploring, and so far the norm has been:   Plains Forest Birch Forest Hills (If I'm lucky) A Swamp   These seem to be the only biomes that want to spawn in my world. I can find others, if I go searching for them (flying about in creative).  Basically, I'm sick of this world generation. I want a bit more diversity in my worlds, so I was wondering what can I do to open up a bit more of a biome diversity in my world? Eg. restrict what biomes do/don't spawn?

Are there any differences with regards to chunk generation or other settings in single-player vs server mode of equivalent versions?  I have a map I'd like to host on a private server for my friend to play with me. However, when I'm on the road without ready internet, I'd like to play it single-player as well.  Will this cause any issues, especially with chunk generation, drops, items, etc (i.e., getting a different chunk generated in server-mode than single-player would have created), or do all server-client version pairs (I'm using 1.6.2) use the same game code?  The main point is that I don't want gameplay to change at all, between single-player and server mode.

Basically, I acidentally spawned too many ArmorStands due to a wrong code writing , resulting in the game crashing, and wanted to know how to delete those armorstands from the World save folder. They hava names and I belive they also have a scoreboard set, if that helps.   I have already tried to open the world but it crashes, I tried to open a server (Since it worked the last time I tried it) and killing it all from the console but, different from the last time, it crashed before killing them and now I just tried MCedit but it crashes as well.

I've recently changed to the new Minecraft launcher, and I have noticed a change in the .minecraft folder layout. I can no longer install mods just by copying it over into the versions/1.6.1 jar file, as this file refreshes every time it is launched.  For those who don't know what I am talking about, here is the new layout:    I am specifically trying to install Optifine, which does work with 1.6.1. Where do I drag in the mod files now? I can't seem to find a jar file that is suited to it, except in the version folder, but as I stated above, this refreshes every time.  After copying a recent version and renaming it in the version folder, I get this error in the development console:   Unexpected exception refreshing version list java.lang.IllegalArgumentException: Version '1.6.1' is already tracked     at net.minecraft.launcher.updater.VersionList.addVersion(VersionList.java:91)     at net.minecraft.launcher.updater.LocalVersionList.refreshVersions(LocalVersionList.java:44)     at net.minecraft.launcher.updater.VersionManager.refreshVersions(VersionManager.java:47)     at net.minecraft.launcher.Launcher$2.run(Launcher.java:164)     at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source)     at java.util.concurrent.FutureTask$Sync.innerRun(Unknown Source)     at java.util.concurrent.FutureTask.run(Unknown Source)     at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source)     at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source)     at java.lang.Thread.run(Unknown Source)

I recently opened a map which I thought was broken, because I could not load it anymore. I increased the memory for the Java VM to 8GB and now I can open it but it is impossible to play on this map, because there are thousands of cows! I think this is why the map could not be opened with 768 MB of memory for Java.  So my question is, if there is any tool with which I can remove those cows. I've heard of several tools to manipulate the landscape, your spawn point, etc. But I don't know if there are tools that let you remove and place animals without having the map opened. When I open the world I have like one frame every 5 seconds...  Can you recommend a tool with which I can remove animals or other entities from a Minecraft world?

This question is regarding the minecraft Beta 1.8 prerelease -- I have a beautiful house in single player survival which I'd like to record while flying.  I want to be able to change the game mode of my survival map to creative to be able to fly through it without installing a mod. I know it is possible if you run the map on a multiplayer server via the command /gamemode &lt;user&gt; 0|1 but I want to achieve this in single player :)  I think this would be possible through editing your level.dat file as I think that's where the game mode for the map is stored.

I play on the DivineJourney modpack with a friend, but he wants to constantly spawn things in. Is there any way to allow him to be able to use the teleport command, but not be able to spawn in items?  I've already locked the NEI mode to Recipe.  I've looked around for a mod for plug-ins for Forge (as thats what the server is on) but I couldn't find anything thats up to date. I found Sponge, but thats for 1.8+, and I need 1.7.10.

I built this 2 layer mob spawner trappy thing in the air. It's 24x24 but no mobs spawn inside :( No one falls down and I've opened it up several times to check; nothing inside either.  It's a standard thingy with 4 water flows, forcing mobs to the middle and drop down. As said I've opened it and nothing inside  It's dark, 100% sealed with stone.

Not long ago I started a minecraft world on a new 1.9 snapshot and friends wanted to join so I took my world file and dropped it in a server. Now a little later they are losing intrest in it already but I'm still having my fun. I tried copying the world file back in the saves folder but then I ran into a little problem. I started with the progress I was in before I put it on a server. I was in the same location with the same health, hunger, items, armor, ... This wasn't all a problem when I transfered it to a server. So how do I end up with the progress I was at when I last played on the server?

What command do I use to spawn to a different area in my Minecraft server?    I spawned on a island and there is no land near?    I really need help and my friends want to join and they are getting tried of waiting.

In Adventure mode, I'm trying to let a player get blocks that he can place later, is there a way to do it directly or do I have to change them in his inventory?  Situation: The player gets a tool that will allow him to clear a boulder blocking the road. Further down the path, he encounters a broken bridge, and I want him to use the blocks he gathered before to rebuild it.  At the moment, if I build the boulder with blocks having the CanPlaceOn tag, the tag disappear when the player destroys them and they go in its inventory.
