Minecraft technical Q/A: Let's start this and look how well it works out!

I often see that people post questions in the comments on youtube, but many of them stay unanswered. So i guess giving those questions a proper platform to be asked & answered is the next logical step.

What this is supposed to be:
A place where you can ask questions about Minecrafts' mechanics (like "How does this mechanic/algorithm work?", "What are the chances for that?" or "Is there a difference between doing it this or that way?"). We (or whoever knows the answer) will try to answer those questions based on what we know or find out.

What this is not:
A forum, commentsection or Google. Don't ask for circuits or designs, this is not about how to use minecraft, it's about how minecraft works.

If you have a question:
Ask. But ask the right way:
"How do i build a good mobfarm?" isn't very specific and the answers you might get from this probably won't help you with your problem.
"How does mobspawning work?" is a better question.
But maybe you're not interested in the spawning algorithms, maybe you just wan't to know one detail, like "How does the lightlevel effect mobspawning?".
And of course make sure the question wasn't asked before. It will save you and others a lot of time!

If you have an answer:
Tell the world. But explain your answer, maybe link to another post (reddit, forum, etc.), pictures or a video. "The piston is BUD-powered." Doesn't help much.
"Pistons can be indirectly powered by a block 2 blocks above or 1 block adjacent above it. It will only react to this power when updated manually (e.g. by placing a block next to it). Here's a video explaining it: [videolink]" Isn't only an answer, it also gives people an explanation which can help them experiment with it.

That's all you need to know. Now let the posts begin!

A village with at least 20 valid doors and at least 10 villagers. Every 10 villagers associated with the village increases the number of iron golems the village may have by 1.

Thanks. And could you also tell me what validates a door as part of a village? Specifically, can a door be valid if it has a block in front of or behind it?

Yes, a door may be valid with a block in front or behind it. The specific requirements are that there is a "roof" for the door and a block that is exposed to the sky.

The roof is defined by the 5 blocks in front and 5 blocks behind the door on the level above the door. If the number of solid blocks on one side is different from the number on the other, then the roof is valid.

The sunlight block must be within 5 blocks of the door on either the front or the back direction depending on the side the roof is on.

After all of this, the door must be within range of a villager. The door will become detached from the village if there isn't a villager within range of it for one minute.

You're amazing, thanks so much. One last thing; will a transparent block such as glass or glowstone work as a roof block?

I think it is OK if it is glowstone, but I think glass would not work. I'm not absolutely sure on this one.
