Okay, so I haven’t watched it all yet, but when I get around to it I will. I did know the first few things and judging from one of the later things I saw (extended redstone device using cobwebs) they’re things I know or have at least heard of.
But I have a few things you may not know…
InfiniteObsidian Glitch: Basically it’s a glitch that uses blocks such as redstone wire to generate obsidian without destroying a lava source. Notch knows about it and never planned on fixing it, so technically not a glitch.
Fun facts about Mob Spawners: Most “normal” spawners (Zombie, spider, skeleton, etc.) spawn the monsters in air no more than 4 blocks away from the spawner. They also have caps based on the number of monsters in the area. They spawn in light levels of 7 and less. Exceptions: Silverfish: Spawn as listed above, but also will spawn on Cobblestone, Stone, Stone Brick that sort of block, no matter the light level. Blaze: Light levels to spawn are 14 and less.
Redstone: Interesting little device you can make. A binary signal that travels along a single wire. In other words, you can send a byte of data (that’s 8 total 1s or 0s or any combination) along a single piece of redstone (Or theoretically more than a byte). Makes some devices much more compact and allows for better user input.
Sheep: There are 5 different naturally occurring colors of sheep. White is the most common, while Black, Light Grey, and Grey are all fairly equally common. There’s one more type that you’ll probably never see: Pink. It has about a 0.125% of spawning.
Lightning: So thunderstorms happen every once in a while, and while the lightning effect looks cool, it also does some cool stuff. If lightning strikes a pig, the pig will transform into a Zombie Pigman. If the lightning hits a Creeper, bad things happen. A blue aura surrounds the Creeper, making him “Super Charged”. A Super Charged Creeper blast not only does insane damage, but also leaves a much bigger crater. Fun fact, the lightning strike actually sets the Creeper on fire, but because it always rains during a storm, the rain usually puts the Creeper out. Speaking of fire, killing a cow or pig or chicken with fire (either flint & steel or an enchantment or whatever), the animal will drop the cooked version of it’s meat.
