Wow, this is the best Tic-tac-toe game i've ever seen !
Congrats !

It's time for a really little demo version !
You can walk on a ridiculously tiny island with a little house.
This is more a proof of concept than anything else.

If you want to try it, open the attached archive and use nCraft.tns.
WARNING : it has never been tested on a real calculator. And I don't have CX support yet.
You can go forward with a, backward with z and you can turn the camera with the arrows.
The collision detection is very simple and doesn't really work.

For the ones who want to see it but don't want to download it, there is an attached screenshot.

Your snake game is awesome !
It really reminds me the nokia version... And the snake on the title screen is really nice

Great work !

Test ALL the addresses
http://hackspire.unsads.com/wiki/index.php/Memory-mapped_I/O_ports

Timer 1, Timer 2, and RTC.
The choice is up to you.
Beware on the emulator, it seems that the RTC can't be modified since it is based on the system (windows) time.

Thanks !

What is RTC ? If that means Real Time Clock does that mean there is a clock on the Nspires that I never noticed ?

Yes...
A while ago, with ndless 2, I made a little program to use it, but I never finished it.

If you get minecraft to work on the CX, you win.

I hope I will
But don't think it will really look like the PC game : much slower, no textures, no nice physics...

Please try with this code, it should work...

I don't think that TI can change their mind.
We are a tiny part of all the Nspire users, and they just care about teachers.

In my opinion, they don't trust us because they think that it could "hurt" them more than it could help them...

(BTW, downrates don't exist anymore )

So, thank you compu for allowing us to use the CAS on non-CAS nspires !

@Hayleia :
Oh, I'm really sorry, I didn't see your post !

I have a stupid answer: Join the Ndless team ?

I would like to help them, but this is totally out of my programming capacities. I'm just a little programmer who makes games with a SDK. Moreover, I don't think I have enough free time.

@ExtendeD :
I understand your point.
But it's quite frustrating to create programs for the Nspire, while TI does everything to block it. I know it has always been like that, but it's sad to realise it.
Moreover, it seems that TI secures more and more their OSes, so I think that ndless 3.2 won't be here before a while, despite your amazing work.


Anyway, I thought a lot about this last night, and it would be stupid to stop calculator programming.
I might not stop this project, but it is paused for sure (for at least one week).
I still feel discouraged, but I do want to help the community, and it seems that giving up isn't the right thing to do.

It's quite easy with parametric equations...

Just use {x1(t)=2, y1(t)=t}
