Talk:Grass Block/Archive 1

Fences
While constructing a farm, I noticed that grass will apparently never spread to or from (I'm less certain about the second) a block with a fence on top. Not sure about this since grass spread is probabilistic so I'm not adding it to the page, but if there's confirmation... —KPReid 07:04, 17 October 2010 (CDT)


 * Grass is weird in alpha right now. Some grass seems to stay alive in odd places, its living under fence, but wont spread under it? Theres grass in the bottom of a pond i made too, and its been there for a while. Grass supposedly needs light to live, so why is grass still there in covered up creeper-craters? I dont know.Toadbert


 * Same happens with glass. Nbord


 * Perhaps the game won't let it grow there because the fence still counts as a "block." It won't grow there because it thinks there is a block on top. This may also explain the problem I had a while ago; I set up a path of dirt to grow some gras into my base, but there was no grass growing where I had placed a sign. It took me hours to figure out why it wouldn't grow. -buster2Xk


 * It doesnt spread under fences, torches, doors or glass... maybe it just doesnt spread when under a block? -F1racer101 04:56, 11 December 2010 (CST)
 * It appears to spread under all pseudo blocks that will occupy a block but aren't solid. So torches, minecart tracks, redstone all will be spread to but fences and glass still count as solid --Flippeh 00:00, 22 January 2011 (UTC)

Animals
Grass is used to deturming where animals can spawn. If you get grass to grow in a deep cave then animals can spawn there.--Tnarg 18:47, 21 October 2010 (CDT)

Grass Spawning
I know that dirt cubes will spawn new grass if they are close enough to another grass cube. What are the rules for this? Do they need to be orthogonal? Does it only happen with enough light? How far away (horizontally and vertically) can the dirt cube be from grass for a chance of grass spawning? --Mozai 18:55, 27 November 2010 (CST)
 * I've been putting a bit of research into this, not complete yet but I figured I'd dump my notes here so as not to forget them... Alpha 1.2.6 of course (current at the time of writing).


 * Grass seems to require a minimal light level of 4 to grow (keeping in mind that a torch provides 14, meaning it'll grow up to ten tiles away from a single torch in an otherwise dark area). It will only grow if another grass tile is next to it (diagonal joins count). Grass may spread up to one dirt block higher, or three dirt blocks lower, then the grass block in concern - I've yet to conclusively test how far away it can be on the horizontal plane, but it seems there's a no-gap limitation there. It seems grass travels downhill significantly faster then it does uphill (it may take multiple game days to go up a block, whereas downhill travel tends to happen within a real world minute). I'm uncertain yet whether grass may travel diagonally downhill at two/three blocks lower then the source block, but it may certainly travel up/down a single block along the diagonal (although uphill diagonal travel takes an age).


 * Grass will not die if deprived of light, however, placing another solid block on top of it will eventually revert it back to dirt. - Bomb Bloke 13:15, 10 December 2010 (UTC)

Beta 1.5
Is anyone else having a problem with the sides of grass blocks appearing as a black-ish color since the update? It seems to be similar to the texture used for "Crying Obsidian" except colored green instead of blue. --Teska Jadestar 16:56, 19 April 2011 (UTC)

Are you using a texture pack from beta 1.4_01 or earlier? That might still have the Crying Obsidian texture. Zkyo 17:07, 19 April 2011 (UTC)
