A solution would be to make nGL support true monochrome rendering and convert textures to monochrome before needing them.

nGL doesn't care about colors or such things, it just sets every COLOR on screen to a COLOR in a TEXTURE.
4-bit doesn't work in C and if I use 16 bit I wouldn't even have to change the definition of COLOR as uint16_t.

How close would redstone/related stuff be?

Or even lighting?

If you mean progress: I didn't even begin. I will when I have time, motivation and some other projects finished.

Just a quick question: How much could I increase startup time?
In v1.0 I'll implement some more optimizations, but it'll result in a slower start.

A slow start doesn't bother me since it'll improve the game overall.

What about being able to interrupt startup and emergency quit ?

That'd be possible by either writing some asynchronous worker functions, which is a total mess or keyboard interrupts which I never got to work.

So, not until I find a solution for keyboard IRQs.

I was more thinking of putting key detects in the loops that precompute datas - the ones that occur when we see the "Crafti" title screen, that way you can detect emergency-quit.

Most of the time it's doing a fread call, so hardly interruptible. But I'll insert a isKeyPressed(KEY_NSPIRE_ESC) in the middle somewhere.
Probably when "Loading" is shown first.

Voginator, you should do coroutines based calculations. FOr HBE for instance all subroutines give the hand to another routine, even if they didn't reached their goal.

For your case, you could do something like this

Code: [Select]
LOOP
  Calculate a batch of things
  Draw
  Key update (the order of the actions doen't mind)
ENDLOOP
for the batch calculations, you could track the index or the loop counter.

That's called game/render-loop and I'm using that already, combined with a state-machine.
But for cleanup, for instance, I'd need to return some value to inform the whole call stack up to main that the user requested a termination.
(I dislike atexit and there may be some problems with bFLT..).
Also, most are some calls to drawTexture, newTexture, loadTexture, resizeTexture and I don't want to just throw some if(!isKeyPressed) in there. Also the key press detection itself would take longer than the rest of the loop body.
A interrupt would be the most clean solution, but I'll not implement anything more than some additional isKeyPressed in between until I found a solution for keypad interrupt handler crashing occasionally.

Wow ! Those are good improvements! :o

Nonetheless, the game... laggs. Why does it lagg more with water and lava?

Feature requests:
  • Be able to open the menu or quit the game even when there is the "loading" label.
  • Move on the items selector menu with the touchpad.

I think the priority is the speed up all the "loading" during the game.

In v1.0 I'll implement some more optimizations, but it'll result in a slower start.

I think the speed during the game is much more important than the startup time. I think you can grow it up to 40 seconds (currently 22 seconds) if you add a loading bar.

Thanks for your work! Do you mind if I upload it on tiplanet?

That's a bug I found yesterday by accident and I already fixed it ;) (Water was spreading to blocks even if there's already water)
And it will always be somewhat slower if water and lava are visible as blocks under water or lava still have to be drawn as you can dive.
(I COULD rerender the world if you're submerged, but that'd take some seconds, which would be very annoying if you're swimming just beneath the surface)
That's also the reason why I retained from natual water sources such as seas, oceans or underground lava.

I can insert a if(keyPressed(KEY_NSPIRE_ESC)) somewhere in the middle of the splash screen, that shouldn't be too bad.

Ok, will do.

That's terrain generation and it will probably not get much faster.. :( Unless I can find a better way to generate terrain.

I hope I don't reach 40 seconds, but it's likely the framerate will increase by ~20-100% in some cases!

Not at all, if you put a link to the github release page or this thread, just so that everybody can find the latest release and source code.

Wait, that means that if I stay on a "region" where everything is already generated, I don't have that loading anymore ?
Maybe you could add an option or something to waste 1 minute of time generating a "huge" map to save time later by not generating anything anymore ?
