Software to install the CAS on the non-CAS is also most likely legal (after all, we are not distributing TI's files). The current agreement right now, though, seems to be to avoid financially damaging TI in order to placate them (Ndless does not make them happy).

The textures will tile in the final version.
You will certainly be able to stand on lower walls (after all, what use are stairs if you can't climb them?)
A word of warning: this demo is very buggy. Don't expect too much from it.

New demo! Walls now have variable heights. Sadly, the floor-drawing code doesn't work (so when you see the top of a cube, bad things happen). Also, the sprite clipping behaves strangely sometimes (since the old 1D Z-Buffer no longer works). critor: do you have the formulas/source code for drawing the floor segments? I can't seem to figure it out

Bubble sort?

Does anyone have advice/code/pseudocode on how to do multiple height walls? I could use some guidance on how to optimize the feature (I think I have the math right now, but I haven't started implementing yet because it looks messy).

Or use calc84's utility.

You could always PM steev for his email address, then email him the links.
As for sales increasing, ticalc.org should really change their Nspire page to reflect the new developments. Otherwise, people will still think the Nspire "lacks programming ability".

How old is the Nspire? Is it one of the new touchpad Nspires?
No, you cannot run the CAS OS on the non-CAS that way (it validates the image to prevent that).

Really trivial update attached changes the quality keys to H and L.

Latest trivial update!
Press [Enter] to toggle rendering only every other column (you might have to try a couple times to make it work; the keys don't have any delay so it is possible to switch it on and then off again in one keypress).
@Builderboy:The speed concern is why I have implemented drawing every other column (free 2x speed gain at the cost of a negligibly uglier result).
@DJ Omnimaga: The floors will all be separated by textured walls, so no two floors will ever intersect.

Try the new CAS version attached.

I remember scaling a 160x120 up to 320x240 a while ago. It wasn't any slower (because since the ratio is 1:2, I can just fill in 4 pixels for every calculated pixel).
I might render every other column instead of scaling up a half-sized screen, though (so I'd get a 2x increase in speed).

Try the new attachment.

Well, there's not much progress right now--I don't actually have multi-height walls; I'm just changing the code a bit so I can add them later (hopefully in a couple days).
My current plans for the engine (roughly in order of priority):
* Add multiple height walls
* Speed up sprites a bit (so sprites behind you are completely ignored)
* Add doors
* Move code to their own files so that other people can use it
* Add fake sky textures
* Add support for moving objects
* Write external data loader
How does one access files in C on the Nspire?

New slightly changed demo:
* Looking up and down is out for now, in preparation for multi-height walls.
* F key toggles floor textures.
* * and / keys change the resolution.
critor: never mind the floor question, I figured out.
