I'll begin by saying that I only understood a fraction of what was described in this blog entry, and if you also have no experience with coding, you'll probably be in the same boat. That said:
Notch's latest blog post, mostly sharing an email from one of the developers of a long-standing plugin which
modifies the height limitations of Minecraft. Here's a short bit taken from near the end, most technical details aside.
I have to say that the game was *remarkably* performant with the Y height pushed up to 256. I imagine 512 might not be too bad on my beast of a machine, either, though 1024 would be pushing it. That said, one of my short-term ?just for fun? goals is to see if I can?t get the Nether to populate from 0-127, the main world from 128-255, your Sky dimension from 256-383, and then that one group of modders? new dimension, the Aether, from 384-511. That would be epic.
Alright, so this guy is strongly implying that, yes, that sky dimension Notch made a passing mention of about a month ago is definitely, absolutely going to be in 1.8, which will probably be a large feature of the adventure update. However, with the way it's mentioned as a completely separate thing from the Aether, this leads me to believe that it really is just that: a completely separate thing from the Aether. I'm expecting grass, dirt, stone, snow biomes, water, lava, blah blah blah, the usual stuff you see down on the ground, except in floating island form.
And with less trees.Now, I know what you're thinking: "Well, yeah, one guy did strongly imply that the sky dimension is going to be in 1.8, but what does he know? It's not like he's a part of Mojang or anything, so your assumption that the sky dimension will be in 1.8 is pretty-"
BAM. Ah, good, you're back from watching that, and possibly rewinding it to watch everything before that, too.
Alright, so let's face it: despite all this, there's no way of disproving that they didn't simply find all the right settings to get
this uncanny lookalike of Notch's aforementioned sky dimension into Minecraft through the use of something like the
PhoenixTerrainMod. As it stands now, this is all just conjecture, but, personally? I'm hopeful.
