Bugfix release 0.7.1:
  • If you jump, you don't get stuck in the ceiling anymore if you hold 5
  • Top of block at the top of the world not drawn
  • Almost no stone generated
  • Smoother terrain

How many bits does one block occupy in memory ? Because if you use 32 bits for each block, that is kind of a waste and that's a spot where you could save space, not only in the savegame, but also in the cache (which means a faster game overall :D)

Consider that 32 bits leaves room for data storage for things like chests, redstone, spawners, etc.

Well I don't think 32 bits are necessary for one block. Even 16 is a lot. Since there are less than 256 blocks, 8 bits is enough to know the type of a block, and the 8 remaining bytes can be used for some information (like the number of the chest if you placed several chests), but I don't think you really need 32 bits.

Currently I have a typedef uint8_t BLOCK in the code and the chunk data is a BLOCK[8][8][8] which is directly fread or fwritten into a file.
If I'll add a feature which requires some data storage for a block, I'll either make a BLOCK 16 bits wide or use a seperate array.
A seperate array will be faster and easier to handle than a interleaved array.
For blocks which require more storage, I'll store a unique ID in the extra 8 bits and reference it to the specific data.
But such things are far away now... Probably further away than the next nspire OS release blocking ndless...

Well to remove the post you quoted and which was a test. I was sure I could delete it too, with a red cross button, but now I can't find it.

Bug report in the latest version: I keep getting stuck in blocks it seems because everytime I jump somewhere I can,t move anymore afterward until I destroyed the blocks under me.

Check out the links on the front page for information on getting Ndless 3.6 going.

Just extract the file with 7zip and craft.tns should be in there.
@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.

Ah I see now. Yeah I kept it somewhat low so it doesn't take 3-4 seconds before the next chunk loads. The wait got a bit annoying compared to the older version. D:
