I actually thought about that, but it doesn't make much sense IMHO. One hand for rotation and the other for movement.
And also that would make debugging absolutely impossible, as I couldn't rotate the camera on nspire_emu then.

I also hit a bug in GCC 4.9.0, but it should be faster now, as one of the major features in 4.9.0 is a optimized LTO.

Once Lionel Debroux said that GCC versions x.y.0 are buggy, and when 4.8.0 was the latest GCC, I ran into a bug that gave an ICE when compiling Ndless :P
I reported the bug, and it was fixed in 4.8.1.

The major time between 4.8.2 and 4.9.0 was testing, especially for regressions.. Obviously it was still too short.
I'm looking forward to find out what else it breaks.. I mean, it's just a normal constructor, I don't know any C++ projects without constructors...

I am very interested in wondering if, because the iOS does not support Java, you are actually using mechanics similar (unknowingly) to those in the iOS version of Minecraft?

The programming language has nothing to do with mechanics. But maybe it's just unclear to me what you meant.

BTW: Just found another bug in GCC 4.9.0: Compile anything with pointers with -fsanitize=address and it crashes if LTO is enabled:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=61048
I don't know, maybe it's also present in 4.8.2.

Well on PC, you have one hand on keys and the other one on the mouse.
Same on Android where you have one hand on a virtual D-Pad and the other one sliding around to look around.
I hear your argument about the emu though.

That's how GNU version numbering works. :P Major.minor.patch = overhaul.features.hotfix.

Crafti v0.9
« Reply #247 on: May 06, 2014, 01:15:52 pm »
New major release of crafti: v0.9!
I know, I only changed the minor version number >:D

A screenshot first, can you guess the changes?


New features:
  • Water and Lava: Water has a range of 5 blocks, lava 3. You'll be able to find out yourself how it exactly works :P
  • Inventory for quick-select: Press 5 while in block list mode and you change the block in the current slot. Use 1 and 3 to select the inventory slot.
  • Doors: Open them with 7
  • Wheat: Has to be placed on dirt or grass adjacent to water. If you remove the water, it'll dry instantly. Growth speed is totally random.
  • Selection indicator: I reused the glass texture, in the quick-select as well
  • Swimming: You can swim in water. Not in lava, that'd be dangerous!
  • New blocks: Glowstone, glass, diamond, gold, iron, netherrack and cobblestone
  • Switched included texture pack to Sphax PureBDCraft: The other texture didn't contain water somehow.

Fixed bugs:
  • Most graphical issues fixed: Your screen shouldn't show complete garbage anymore.
  • Fixed jumping bug: No more sliding along walls or getting stuck in blocks!
  • Fixed bottom of grass blocks: It was gravel before. Don't ask me why. I couldn't answer myself.
  • Made leaves opaque again. Not a huge difference in appearance, but in performance.
  • Fixed accidentially overwriting not block-shaped blocks, like flowers or mushrooms.

Known issues (compared to v0.8.1):
  • None!

    you forgot the readme :P
    Awesome !
    Glad to see you could make both the inventory and water+lava, among other things :D

    So epic :D I hope you'll be able to port it to monochrome Nspires as well, or let someone do it for you (yes this is a proposal) ;D

    nGL is open source, so of course everybody can - if that "everybody" wants to.
    It's only the matter of some code switching to 8-bit grayscale mode (there's no 4bit array in C, so that would be quite invasive), and a conversion routine that handles the displaying. And no - I won't do it. At least not this month.

    Do you even know how happy I would be to be able to skrew around with redstone (and related material) on my Nspire?

    I would cry. Tears for you. Bottle them. And then mail them. To you. So you. Could physically feel. My joy.
