I've made a mod that changes the height limit from 128 to 512 (or 256, or 1024, or maybe even higher). It's still pretty rough around the edges, but I'd like you all to try it out!
The mod makes sure you don't overwrite your old worlds (but it can't convert them yet, that's planned for the next version).
Also included is a experimental feature to stretch the output of Minecraft's terrain generator in various interesting ways to get bigger mountains to look at/build with. This is just there for experimenting; I think I'll remove it once I understand better how to alter the worldgenerator.
It comes with a fairly long Readme where the various options are (hopefully) explained, as well as technical info on the modifications I had to make to the save format to accomodate the larger heights - this last bit is for tool writers (for mapviewers and editors and so on). For the interested modder, the output of 'git diff -p' against a fresh decompile by MCP 2.7 is included so you could even play with it.
Download is at http://www.mediafire.com/?2t8cramdgjacwad. Quick install instructions: backup minecraft.jar, put the classes in the zip file into minecraft.jar, delete META-INF, go! For more options, consult the readme.
Enjoy, and I look forward to your opinions and bug reports!
EDIT 1: You can find an intermediate bug fix release, v0.1.5, at http://www.mediafire.com/?1m8n9wy2b33t2mx, this removes the stretching, fixes the lighting problem and makes a special chunk appear at (0,0). Hopefully no other bugs are introduced!
Oh my god is this real?
How much of the entire game did you rewrite?
I changed 20 existing classes in total and added 3. Most of it was in World and Chunk, and most of the rest had to do with map generation. The big work was finding out what needed changing (a simple search for 128/127 won't find all of them!)
Looking at the pictures, I don't think I'll be downloading it until you get the world generation fixed. I would love tall mountains, but not the ones you're getting with this mod :tongue.gif:
You can also turn it off, and get a flat world with just more airspace.
In fact, that's what this mod does if you just install the class-files. You have to start messing around with scalePercentages.txt to get wierder stuff.
Also, in the screenies I turned it up pretty far just to see what would happen. I imagine if you just scale the parts above sea level by a factor of 1.5 or 2, you'd get fairly reasonable looking landscapes.
He said that he prefers not to add mods to the game.
He said he prefers not to add mods to the game because he wants to be creative, and if he added mods they would be taking away some creativity. This mod has nothing to do with creativity (as in new features, blocks, mobs,ect).
For example, he added the McRegion Mod into the game. It's just like this one, it doesn't add "new content" to the game that would ruin notch's creativity.
We must tweet this to Notch. He would be insane not to add it into the main game.
Give me one reason why he should not.
The only reason I see why he wouldn't is because of all the whining and bitching about performance. I however will be installing this when I get in, as my PC rocks and I get no performance issues. Will try 1024 and let everyone know.
If this mod works effectively, it deserves a thousand 's
