Can clear entire hotbar with one click in Creative (new in 12w23a/b)
This doesn't seem to be in the list of 12w23b changes yet. When you shiftclick on the Red Cross in the creative entire, it clears your inventory and hotbar. --18:45, 11 June 2012 (UTC)18:45, 11 June 2012 (UTC)~


 * Well it hasn't been updated in awhile so it might update soon. MaryTheTiger 23:12, 13 June 2012 (UTC)

Buckets
Buckets don't seem to work well with lava, right clicking lava with an empty bucket removes the source but the bucket stays empty. 86.81.124.236 14:40, 10 June 2012 (UTC)


 * In Creative mode, this is intentional; it makes it easier to remove many lava/water source blocks, and you have an infinite supply of lava and water buckets anyway. -- Orthotope 19:47, 10 June 2012 (UTC)

Side of cow's head flashes completely white when hitting them in 12w23b
Can someone confirm this? Looks weird --Nebetsu 00:35, 11 June 2012 (UTC)

Skin gets reset after fighting Enderdragon in 12w23b

Silk Touch doesn't work on Mushroom blocks like it used to.
Don't get the ones with "sides" anymore. Just the standard mushroom block. D: --Nebetsu 05:08, 11 June 2012 (UTC)

Experience has never been "exponential"
I don't know if this is an error on Mojang's part or some wiki editor, but experience has never been "exponential" either "slightly" or otherwise. In the pre-12w22a system the differential xp was linear and the cumulative xp was consequently quadratic. I have no hard stats to go by for 12w22a, but it sounds like the differential xp was constant (17 xp) and the cumulative xp was consequently linear. In the post-12w23a system the differential xp is constant for the first 16 levels, then it becomes roughly linear (it actually fluctuates a bit). This makes the cumulative xp roughly quadratic (the slight fluctuations prevent it from being perfectly fit by a polynomial).

None of these systems are exponential. They are nowhere NEAR exponential. An exponential case would be where you have to multiply the past level's xp by some fixed number to find the next levels xp (either differential or cumulative, the derivative of an exponential is an exponential). An example would be where that number is 2 and the amount of xp required to level up doubles every time. This number could be less than 2, or even less than 1, but the bottom line is that the required xp grows *very* fast in the limit of large levels.

Constant is "order 0", linear is "order 1", quadratic is "order 2", and so on. Exponential technically has infinite order. Granted there are slow growing functions, oscillating functions, and so on that have infinite order, but exponentials are generally considered one of the fastest growing functions (from the perspective of limiting behavior). So, I think its worth noting that the minecraft case is quadratic, not exponential, since quadratic is very slow-growing in comparison when it comes to limiting behavior.

 * You do realize that a quadratic function is an exponential function, right? Bluemilkman 23:51, 21 June 2012 (UTC)


 * Nope. x2 is quadratic (or, more generally, polynomial), 2x is exponential; they are very different terms. -- Orthotope 07:27, 22 June 2012 (UTC)

The /tp command in snapshot 12w24a new features
The New snapshot features it says that there is a new /tp command that allows teleporting between players. As far as I know, that command has always existed, and it shouldn't be displayed as a new feature. Am I just being crazy? Because I am sure it is NOT new, I use it on my vanilla server...

 * It's been in SMP before but now they added it to the new SP-LAN mode. - Erik –Preceding unsigned comment was added by 174.96.152.234 (Talk) 08:59, 15 June 2012. Please sign your posts with


 * Well, the text being fixed so that the information was correct was the concern. I'm sure this has been solved. Angelin01 19:05, 15 June 2012 (UTC)

Lag in 12w25a
Anyone notice a bit of lag in the newest snapshot (12w25a)? Spiders were glitching and hitting me and iron doors would only open for a split second. I downgraded back to the previous one and it was gone. Bluemilkman 19:40, 21 June 2012 (UTC)


 * It seems like it has to do with the new method of garbage collection meant to lower overall memory usage. It was messing with almost everything that has a timed nature. Redstone circuits, doors, leaf block decay, mob attacks/movement. Current solution seems to be to move back down to 12w24a --Sinthrill 23:18, 21 June 2012 (UTC)

Arrows fired out a bow in creative...
In previous versions when you were in creative mode with no arrows and fired a bow, the arrows would fire, but you couldn't collect them after. Now with 12w25a you can "collect" them, though they just get removed from the world and they don't go into your inventory. --76.4.89.161 22:34, 21 June 2012 (UTC)


 * Possible bug or intended “cleanup” feature? MaryTheTiger 22:38, 21 June 2012 (UTC)


 * Given that there was previously no way to remove the arrows, I'd vote for "cleanup". Not even going into survival would pick them up.  You'd need to wait for them to despawn, which can cause issues depending on where/what they hit (seeing as they activate wooden pressure plates and tripwires). --76.4.89.161 23:42, 21 June 2012 (UTC)

12w25a cannot confirm bugs
I cannot confirm these bugs: LB 23:57, 21 June 2012 (UTC)
 * You can only select Adventure Mode game in LAN mode.
 * Mobs and entities are frozen causing the game mostly unplayable.
