Jup, that's an issue with chunk loading. If the view distance is at 1 (the current minimum) some adjacent chunks aren't loaded because I iterate through each chunk and do a if(dist <= sqrt(x*x + y*y + z*z)) to determine whether to render it. Did noone yet find the bug that a chunk isn't rendered if you stand on it and look in the wrong direction? :P

@DJ_O I had that glitch too, but it got fixed by making the field of vision a bit longer by pressing +. I think what's happening is you're jumping into a place before the calc has loaded it.
If you have any issues please let me know! Otherwise I may think it's not as important or it doesn't happen often.

For me it pretty much happens everytime >.< (well, unless vision is set to high)

It's really nice. I think the critter you should add first might actually be, if it's possible, a view of Steve himself. Or pigs; they're tasty. :)

I am unable to test it, so I don't know if smelting and crafting is in yet, but if not, it probably should be added as soon as possible.

Just a short update, I'm currently not developing crafti, I'm currently working on finishing newlib integration into ndless.
Then I'll finally be able to use the C++ stdlib fully, including iostream, fstream and such.
When it's ready I'll optimize world generation speed and speed in general. I think I may get another frame or two per second :)
Any other issues except those which are generator related?

A few graphics glitches, like sometimes you can see through blocks when viewed at a certain angle (happens a lot when you dig underground), but overall it's pretty good. Also, if you dig too deep you fall out of the world. Bedrock would help a bit.

YEah I agree about bedrocks. Also do you think, grass, water and lava (including their flow/physics) would be hard to implement?

Really, REALLY cool!

Could there be a readme file though please?

Grass flow? Do you mean grass spreading onto nearby dirt blocks?

What should be in there? Instructions, controls, changelog, license?

If the terrain generation is slow on the calculator, then maybe there could be an option to generate maps on a computer and then transfer them to your calc. Just an idea. :P

Having the standard library would help ndless development immensely. More power to you.

The readme should include instructions

Crafti is now on GitHub.
Changes in v0.7.2:
- Faster world generation (should be fast enough now)
- Fixed bug if the maximum chunk distance was too small
- Other texture pack, wooden planks look a bit weird. If you can find a better one with a suitable license please tell me!
- Add README.md

Yeah, it's just a bugfix release, I'm now slowly integrating the new possibilities with full newlib+libstdc++ (e.g. fstream) and fixing bugs on the way.
There's a lot to clean up now, so progress may be a bit slow.

Nice job! :)
Did you ever get elf2flt to speed up when linking against libstdc++? When I tried last time, it took forever and froze my computer.

Also: in the README, it says you're using something called PerlinNoise, which is licensed under the GPL. So shouldn't the whole program be GPL'd to comply with the license?

Somehow the bug resolved itself with the last change to the libstdc++ compile flags (I think -fpic)

It's basically CC-NC-SA except for the PerlinNoise class and the texture. The texture didn't contain a license so I didn't care.
I don't know whether CC-NC-SA exists or is compatible with the GPLv3, I'm not too familiar with licenses but I don't think it was that hard of a work to copy the offical PerlinNoise source and change the syntax a little. If you think that's an issue, I'll probably make it GPLv3.

CC-NC-whatever isn't compatible with GPL.
The texture shouldn't matter because you aren't linking with it.
