command block (missing @f)
was  removed or why it isn't working? -- 16:17, 12 October 2012 (UTC)
 * There has never been @f. What did you think it did? ⑬㊲ 18:32, 12 October 2012 (UTC)
 * Wasn't there a command for the farthest player? --undefined – Win8RPx64, Java7u7x64, NVIDIA GeForce GTX 560 12:05, 14 October 2012 (UTC)
 * There was and  is  an, i am not sure why you do not have that command available, was this in single or multiplayer? Try it on both to see if it works.  17:25, 15 October 2012 (UTC)
 * Sorry. I didn't realize that got added to 12w38a. ⑬㊲ 22:17, 15 October 2012 (UTC)
 * There was an @f but it was never released in a snapshot. Now that all targets return lists, you can do: @p[c=-1] to return the furthest player. Check https://gist.github.com/3736487 for why that works. —  07:47, 16 October 2012 (UTC)

lighting glitch
i get the lighting glitch with the upside down half slabs (screenshot). can anyone confirm this? all drivers/java up to date. -- 02:01, 13 October 2012 (UTC)


 * Yup, I believe the fix that made that old problem better was reverted because it caused horrible lag. It will be reintroduced once Dinnerbone has finished wrestling with the lagmonster, I expect. Then ugly dark spots under slabs and overhangs will finally be gone. --] 16:15, 14 October 2012 (UTC)

Inventory management UI refinements
a You can't hover empty inventory slot and press 1-9, to place item there, but you can swap items by pressing 1-9. -- 15:20, 12 October 2012 (UTC)


 * Seems like more of a feature, as annoying as it is, to just simple swap items like that. Not very useful in my situation, but still a nice feature. -- 15:32, 12 October 2012 (UTC)
 * Also: YOU'RE DOING IT WRONG. The idea is you hover over an item and if you have an empty hotbar slot it will transfer that item to that slot, much like shift click. -- 15:34, 12 October 2012 (UTC)
 * Take no offense to the YOUR DOING IT WRONG thing, i like to joke around :D -- 15:35, 12 October 2012 (UTC)
 * No I am not, I'm simply noting it doesn't work other way around. And that makes it annoyance. -- 16:01, 12 October 2012 (UTC)
 * you send an item to the specific slot of the hot bar pressing 1-9, you can't send/switch back if you click in the hotbar, since the game can't know to which item/block you want to change it with. Just use shift or press in the inventory.
 * He want to say, that he pressing number key on empty inventory slot and expect to corresponding item from hotbar to move to that place. Basicly to swap item with empty space. — undefined 17:33, 13 October 2012 (UTC)
 * Imagine how quickly you could organice your inventory from complete mess with this ability. -- 19:18, 13 October 2012 (UTC)
 * I definitely agree. Imagine if Mojang just took the week to relax and fix and put in all the annoyances. It really adds up and makes the game better, plus it gives a better sense of accomplishment because you fixed a lot of things!-- 20:54, 13 October 2012 (UTC)

Out of Memory Discussion

 * smp Also getting OOM crashes with snapshots above 12w36a. I've tried running the world through some corruption fixing tools but none is reporting any errors. -- 20:36, 15 October 2012 (UTC)
 * One thing you should try is running it with more allocated memory to use, when i first ran my bukkit server it crashed every few minutes or so because i failed to give it enough memory to use. if that does not work then your world MUST be corrupted. 13:55, 16 October 2012 (UTC)
 * Are you saying that 2GB of memory is not enough for 15 slots with vanilla Minecraft with no mods loaded? I find that very hard to believe. And, a few snapshots back (I believe it was 12w38a), I started a brand new map that the server generated, and still continued to receive OOM errors. This has been happening for me with all snapshots after 12w36a. I've even gone up to 4GB and still received this error.-- 14:42, 16 October 2012 (UTC)
 * Then possibly server generated maps are for some reason laggier than others? Otherwise then playing a map serverside is more laggy than playing it singleplayer? You are probably right, 2gb should be enough, when i first ran my server it was only getting somewhere around 1gb. As soon as i get my pc to 64 bit, i will have more RAM available for use. 14:57, 16 October 2012 (UTC)
 * I can't affect the allocated memory as it's the hosting provider that sets it. It's been running fine with 12w36a, anything after seem to cause GC OOM errors. As says, he is running with 2GB of memory and it still crashes for him. And my server crashes  after a while with only 1 user online so something is obviously not as it should. -- 16:46, 16 October 2012 (UTC)
 * The idea is that you download the minecraft_server.exe from the wiki as of the snapshot you desire, run it, and connect to it on your own PC, you do not have to be online to do this. You will als experience no connection lag, as you are hosting the server. My PC is capable of 4g of RAM, but until we upgrade it to 64 bit from 32 bit, it will only use 3G of RAM. My servers always run smoothly because of this. 17:24, 16 October 2012 (UTC)
 * What's the sense of testing a server if you are going to connect to it locally, and not have it available for others? I host my server on a 64-bit Linux server in my house, and have people connecting to it from all over the world. There's a guy on there right now from Germany, one regular player on int he morning is from Australia, and I have others that regualary join the server from Sweden, Finland, UK, and even one player from China. To me, this is how the snapshot is suppose to be tested - Put it out there for the world to connect to, and really give it a good shake down. And even with a home broadband connection, I have very little problems with lag. Any lagging issues are usually because of the player's local PC or Internet conection, not the server.-- 17:47, 16 October 2012 (UTC)
 * The sense in running a server on a pc in single is so you do not get connection lag, it is still mutliplayer, just because you are connecting to your own pc run server does not make it single player for you. The purpose is to test the features, to see if they work properly. That is usually how people test them, so you know that any problems happening are not related to a bad connection. It also is much more quick than sending an Email to someone or having your friend do it, since all you do is in multiplayer when connecting just connect to the localhost, it will automatically connect you to your server. It makes alot of sense to simply run a server on your own PC, that is, unless your PC cannot handle a server running (Highly Unlikely) 18:55, 16 October 2012 (UTC)
 * I guess we just have to agree to disagree. I have a different idea on how to test the snapshots than you have, and at the same time, I feel I'm filling a demand that many people want. It's not unusual over the weekend to have all 15 slots filled, and I can't even get into my own server. Many people have commented how they have been looking, but can't find any other than mine. if I could, I would add more slots to it, but this is pushing it as it is for bandwidth (I notice it on other devices and just web browsing when all 15 slots are filled). And even with the crashing, I might not be able to restart it for a few hours, but as soon as I do, there are people jumping on right away.-- 19:33, 16 October 2012 (UTC)
 * Well, hard to test the server for memory issues locally by yourself. Besides it was the OOM errors in SMP that where reported, not "singleplayer". -- 20:54, 16 October 2012 (UTC)
