Well, OS 1.7/2.0 should last you a while, at least for math purposes. By the time TI adds proper graphics and I/O commands to Nspire BASIC, we'll probably have Axe ported to the Nspire

Yeah, given the limited editor capabilities, Axe is excellent.
I wonder if Builderboy will finish his BASIC editor.

Non-CAS clickpad has the most hardware, plus immediate Ndless compatibility. I recommend it.
Inevitably, some day the CAS OS will be thrown onto the non-CAS, and then CAS owners will be sad that they have no special keypad.

Benryves was talking about writing a tokenizer for Document DE files a long time ago on Maxcoderz.
BBC Basic is also slower than Axe, unfortunately. However, it makes up for it by being a lot more user-friendly (Axe is limited to available tokens,which hurts its usability). It is also nearly compatible with the many BASIC dialects from the 70's and 80's, making it a lot easier to port programs.

Yeah, the learning curve on BBC Basic's editor was a bit steep  Its a nice language, just overshadowed by Axe.

The dimensions have to be a power of 2 in order for the bit-shifts and fast modulos to work.
Also, the final version will have a lower framerate, both due to the extra work involved in drawing sprites and the fact that right now, 40FPS on the Nspire's crappy screen causes blurring.

The Nspire has no random() function; the one in Ndless is called rand().
That could be a possible reason for your crashes. I've experienced crashes when calling non-existent functions before.

The tiles are 64x64 pixels, in case you are interested. The bigger the better, I guess.
But I think 128x128 may result in some icky accuracy issues in the integer arithmetic. I will check it out over the weekend (not tomorrow, since I am away). It also uses 4x the storage, but that's 16KB, hardly a concern with the Nspire's enormous 32 MB archive. Hooray for no more memory issues, ever!

The version with textures is even faster, thanks to a change in the code  Combining floorcasting with ray casting is certainly possible; however, much of the Ncaster code needs to be altered to support that (namely, the entire thing has to be converted to integer arithmetic). I originally intended for this to be part of a racing game engine (in the style of F-Zero). I really need to go find some tiles and a map to render. That would make the demo look so much better. The current map is 64x64 tiles. How big do you guys think a racing game's map should be? The map size is hard-coded for efficiency, so I need to know it if/when I make a release.

cd "My Documents", maybe?

Do you have a link to the algorithm you're using? The only thing I can think of at the moment would be x, y going out of bounds.

There are some rather scary programs out there, but they are not likely to get on your calculator.
Most of them don't cause irreparable damage anyway.

This is quite unfortunate Have you tried chilling the drive? Rumor has it that sticking it in a freezer for a day will help with the recovery. I hope your new projects do well! Just out of curiosity, which math camp was it? EDIT: Typo ("day minutes" )

I can use my Nspire as a flashlight now!

Why is your for loop for (a = 0; a == 10; a++)? Shouldn't it be for (a = 0; a <= 10; a++)?
