Talk:Composter

Could we also rank them by % chance, not just Alphabetically?
I.e., like the Snapshot description Page:

10% chance: all saplings, all leaves, all types of seeds (except nether wart), (sea) grass, sweet berries, and (dried) kelp. 20% chance: dried kelp blocks, tall grass, sugar cane, cactus, vines, and melon slices. 50% chance: wheat, lily pads, melons, sea pickles, pumpkins, apples, potatoes, beetroots, carrots, cocoa beans, all mushrooms, mushroom stem blocks (not mushroom blocks), all ferns, and all (tall) flowers. 80% chance: hay blocks, bread, cookies, and baked potatoes. 100% chance: cake and pumpkin pie.

It also helps show those 5 only seemingly specific % amounts. Easier to keep track of same-#'s. Yilante 1 /16 /19  5:02 p.m. 76.209.248.192 01:02, 17 January 2019 (UTC)


 * Th table can be sorted by the chance to compost, by clicking the column header. Having a compact per-chance list in addition to the table might be a good idea, though. 「 ディノ 奴 千？！ 」☎ Dinoguy1000 01:32, 17 January 2019 (UTC)


 * I've added data-sort-type="number" so hopefully it might sort correctly now. – Nixinova Nixinova sig image 1.png Nixinova sig image 2.png 01:35, 17 January 2019 (UTC)


 * And it looks very niice. But as pointed-out in the MC Forum, "their % 's are weird."


 * So we should probably also analyze the best-ranges of given plants /crops /Crafted-Food, yields. So for example, do each by basically-efficiency of input-type to amount of output for it.

Percentages
I really don't think the percentage for wheat seeds is 10%. After extensive testing, I'm convinced it's 12.5%, or one chance in 8 rather than 10. I can do a full-blown chi-square test if anyone wants, but you can see for yourself - run a full chest of wheat seeds through a composter, and you'll get ~31 bone meal.

I haven't yet tested the other items in the "10%", but it seems likely that they also have the higher percentage. TheShadowLC (talk) 13:41, 18 January 2019 (UTC)

I just realized that I made an error in my calculations. A hypothesis test for the true percentage being greater than 10% on my current dataset gives a p-value of 0.137 - a tad high, but nowhere near high enough to reject the null hypothesis. Solution: Collect more data! TheShadowLC (talk) 14:30, 18 January 2019 (UTC)

Sigh, a tad *low*, I meant to type. TheShadowLC (talk) 14:40, 18 January 2019 (UTC)

Okay. Having run 3 double chests of wheat seeds (10368 total) through a composter, I got 196 bone meal, corresponding to 1372 composter levels. I calculate the following:

A one-sided hypothesis of whether the true mean proportion is greater than 0.1 has a p-value of 1.3e-22. I therefore reject the null hypothesis that the true mean proportion is 0.1.

I calculate a 99% confidence interval of [0.12375, 0.14090] for the true mean proportion. That's a range of 1 in 7.0971 to 1 in 8.0803.

The percentage could conceivably be higher than 12.5%. Doing a hypothesis test on that gives a p-value of 0.0138 - much higher than before, but still rather low. TheShadowLC (talk) 18:25, 18 January 2019 (UTC)


 * I just checked looking at several different items that can be composted. The percentages for 4 different items in the 10% category averaged to 11.3%. None of the items I tested were at or below 10%, and none exceeded 12.5%. I also tested 3 items each from the 20%, 50%, and the 80% categories. All recorded percentages were slightly above expected numbers across different items averaging 22.4%, 54.0%, and 82.3%. I agree with ShadowLC that either the real odds are different then the ones listed in the snapshot info or it occurred to me that it's possible some other system might be twisting the odds and giving an increased percentage and at other times may give a lower percentage. The percentages I found were only 1-4% higher then expected values. It might simply be they've configured the composter to always give those percentages at minimum. I used 3 doublechests of items for each item tested as well. Amefeu (talk) 01:23, 24 January 2019 (UTC)

Interesting things about the 10% talk. Are you sure you also accounted for what was in the composters? User-100207953 (talk) 18:28, 26 January 2019 (UTC)

I'm getting 10.7% on my 1st go. Are you sure? User-100207953 (talk) 18:53, 26 January 2019 (UTC)


 * If we account for what is in the composter the percentages Shadow and I found would *slightly* go up but no more then roughly .1%. We are only talking about 6 layers at maximum in a composter left over. Even at the 10% group that would be 6 layers extra among roughly 1200 layers that had already passed through. Definitely not significant enough to worry about. However like I discussed in my reply to Shadow there may be some other factor influencing the percentages yet unknown. We need to see the input amount before we can make sense of that percentage you got before we can compare your data to ours. Amefeu (talk) 21:10, 27 January 2019 (UTC)

Blast resistance
I think that the blast resistance of the composter is 3. Just saying User-100207953 (talk) 12:49, 27 January 2019 (UTC)

Bonemeal gambling
I have discovered with extensive research of 10 tests that if you get 1 bone meal, use it to make grass + Tall Grass + flowers, and put them back into a composter, you receive at 24% increase in bonemeal.

e.g.

I have 100 bonemeal

I plant all 100 bonemeal

I gather all grass, tall grass and flowers

I put them into a composter

I now have 124 bonemeal

Wow!

No fish?
Of all the things compostable, I would expect fish to be included in the list. Was that an oversight in this article, or are fish actually not compostable, like they are in real life? ~ Amatulic (talk) 22:22, 1 February 2019 (UTC)

I also think that there should be bamboo User-100207953 (talk) 22:33, 1 February 2019 (UTC)


 * Stick to Vegetation and Crops (and other non-Meat, Food). And one of those is Potatoes, which can be Cooked (Baked) on also-New, Smoker and Campfire, otherwise all-Meat, there (so a crossover thing, while also only Cookable, Crop).

 * This is ridiculous. A sea pickle is arguably meat, because it's an animal. It definitely isn't vegetation or crop.... and yet you can still convert it to bone meal. So why not fish?
 * Bone meal is an animal product, dammit! It comes from bones, which in turn come from animals, not plants! Of all the things that could be converted to bone meal, vegetation is the last thing that comes to mind. ~ Amatulic (talk) 05:28, 5 February 2019 (UTC)


 * Fish (along with other meat-based items and soups) are indeed not compostable in 19w05a; right-clicking on the block has no effect. – Sonicwave talk  08:04, 5 February 2019 (UTC)
 * As I said, it seems ridiculous that you can't compost anything containing bones. I honestly thought this was an error in the article.
 * It would make more sense for plant material to be composted into fertile soil that can be spread around to create farm blocks without needing a hoe. Somebody clearly lost their senses when coming up with this composter idea. ~ Amatulic (talk) 22:18, 20 February 2019 (UTC)

Data values
So, I was goofing off with commands, and I discovered composters support data values up to 15. Note that they (should) only go up to 8. The podzol texture goes WAY above the actual block up to a point, where placing another (empty) composter directly on top of it will result in the top composter looking as if it had a data value of 7. I feel as if, along with other major bugs, this should be shown on History. I will be posting this to the bug tracker. Fezemerald (talk) 00:52, 28 April 2019 (UTC)

Grass Block percentage
I noticed that the chance for a grass block to compost (for BE) was still not on this page, so I did some testing myself and I'm pretty sure it's 50%. Could someone verify this? 107.77.204.111 19:57, 28 April 2019 (UTC)

Baked Potatoes
I noticed while playing in bedrock edition that Baked Potatoes will not work in composters in Bedrock edtion 73.157.165.244 22:29, 27 July 2019 (UTC)
 * As I said 3 sections above, nothing about Minecraft composters makes sense to me. I put a "java only" tag next to the Baked Potato entry in the table, though. ~ Amatulic (talk) 22:43, 29 July 2019 (UTC)

False crafting recipe
The crafting recipe presented on this page is false, the correct one is :

FENCE-EMPTY-FENCE FENCE-EMPTY-FENCE PLANK-PLANK-PLANK

 * The crafting recipe is not false; it was changed in Java Edition 1.15 to match the crafting recipe in Bedrock Edition. -BDJP (t 10:11, 24 December 2019 (UTC)

Crafting section gives false information regarding nether slabs
The section says only overworld slabs can be used. However, in the current version, 1.16.1, I am able to craft a composter using warped and crimson slabs. Could someone please fix this?

Composter's use for mining
Composters can be used as a vanilla x-ray alternative. By getting into the block and placing any block with gravity on top, the player is forced onto the crawling position, which puts the player's head inside the composter without suffocating it, allowing the player to see through most solid blocks.

This should be added to a section in "usage", or at the very least as a bullet point on the "Trivia" section.
 * It's java-only. Crawling doesn't exist in Bedrock. Although I prefer to minimize trivia sections if it's possible that a fact fits into the main body, in this case discussion of bug exploits should be in trivia. Amatulic (talk) 00:19, 13 October 2020 (UTC)
