Talk:Tick

Tick inconsistency
Article Mob spawner declares that the tick concerning spawning mechanics is 1/20 seconds, whereas this article uses the term tick for a 1/10 second period. I think something should be changed, anyone has any ideas on the subject? | TheKax |  Talk   15:45, 7 August 2011 (UTC)


 * A 5-clock ticks on once per second, so 5 ticks on and 5 off, totaling at 10 ticks in a second. Unless there's a new definition of a tick, I'd say to change Mob Spawner. Purtip31 23:54, 8 August 2011 (UTC)


 * Well actually... there is the game definition of a tick. That definition is used by both redstone and mob spawning and almost any other in-game check. A true tick takes 1/20th of a second, and each "redstone tick" is in-fact two true game ticks. This is unfortunately very confusing and I should probably go and edit the page. *sulks off, muttering*. Also, because the tick governs more than just redstone, though it is most noticeable in that application, it should not be merged with redstone circuits just yet.  | Akyute |  02:38, 13 September 2011 (UTC)

Merge With Redstone Circuits

 * - Ticks don't necessarily have anything to do with Redstone, and renders them a completely different subject, that subject being the physical game engine.

 * - Merge the small part pertaining to redstone with the redstone article: Ticks can be used to measure time. –Preceding unsigned comment was added by 50.104.194.86 (Talk) 01:19, 8 March 2012. Please sign your posts with


 * - I agree with the above statement the first half of the article talks about tick as in the game's loop. But, the second half of the article (Methods to produce multiple or single ticks) talks about redstone circuits, that part should be merged. –Preceding unsigned comment was added by 66.207.116.1 (Talk) 00:16, 15 March 2012‎ (UTC).

 * - As the person above me stated, the second half of the article doesn't have to do with anything except redstone circuits, really. So don't merge the whole page, just the part about redstone ticks. –Preceding unsigned comment was added by NightstormKitty (Talk&#124;Contribs) 00:30, 18 April 2012‎ (UTC).

 * - I agree with the two above me; some of it is redundant but some is not. –Preceding unsigned comment was added by Colabcalub (Talk&#124;Contribs) 21:23, 29 May 2012‎ (UTC). Please sign your posts with


 * - Merging is unnecessary. Just keep the topic together so people can view all types of ticks. - Asterick6 (talk) 06:21, 6 June 2012 (UTC)


 * - The section explaining what redstone ticks are should stay, but the section on designing circuits for short pulses should go. A link can be added to the pulse limiter section of the redstone circuits page. --Sostratus 00:16, 13 July 2012 (UTC)

 * As mentioned in the link above, on every tick, 48 blocks per chunk are chosen for updates. The chance of any particular block being updated is, so the chance of it not updating is 65488/65536. After 47 seconds (940 ticks), the chance that a block still hasn't been updated is  . This is why the median time between block updates is approximately 47 seconds: half of the blocks will have received updates by then. -- Orthotope 01:30, 27 June 2012 (UTC)

To be more precise, 3 blocks per 16x16x16 mini-chunk are chosen every game tick. The chance of a particular block being chosen in a tick is technically not, but actually. The blocks picked are independent, and the same block can be chosen multiple times. Mini-chunks without any blocks that respond to block ticks are skipped to spare computation. The average time for a tick on a particular block (not the median) is 68.2666... seconds. Supposedly the random number generating technique used is somewhat poor, but analyzing it for any biases is beyond me. The code for this can be found in the tickBlocksAndAmbience method of the World.java class. http://mcp.ocean-labs.de/files/jd124/client/net/minecraft/src/World.html#tickBlocksAndAmbiance%28%29 --Sostratus 00:02, 13 July 2012 (UTC)
