I don't know if anyone still use this, but I just finished it.
(I spent too much time on this to give up)

So, here is nSpaint 0.7. It features :

-The same tools and filters as in nSpaint 0.6
-A native-like GUI (in nAnima too)
-A file manager, which can be used to delete images (in nAnima too)
-A tool to copy the current image code to the clipboard (really useful to Lua developpers!)
-A tool to paste an image if there's one in the clipboard
-Undo and redo! (5 times max)
-A option to erase all the image
-A nice color selecter
-Tools to flip/rotate the image
-A filter which replace a color with another one
-A filter which erases a color
-Two filters to increase and decrease brightness
-A 'help' window for each tool
-A splash screen (in nAnima too)
-You can move the cursor with the mouse
-The image is automatically moved when the cursor goes off the screen
-The cursor is moved when you scroll

This looks like a nice project !
I think I prefer side-view.

Good luck !

Wow!
Once again, the Ndless team amazes us!

I'm not sure that the USB key is useful since the Nspire has a huge flash memory...
But it could be used as a very convenient way to send documents to the handheld.

Nice work !
I remember that I did something like that a while ago, but I never finished it.

Adriweb :
Yes, I think it is resetted by any reboot, since the Nspire RTC is.

That's awesome news
Is there a version for non-CX or do we have to use downgradefix ?

I already do it.
The Nspire is fast, but 3D drawing without hardware acceleration takes a lot of resources.
Since there is a lot of cubes to draw, it wouldn't be playable without optimization.

I use several ways to speed up the drawing :
- Only draw cubes if there is an "air" block near them
- Don't draw them if they're not on the screen
- Draw only 3 faces per cube (there are always less than 4 faces that can be seen)

Then I just sort the cubes that will be drawn with their distance from the player (optimized heap sort), no need to use a depth buffer.
So I can manage to have a decent framerate.

Good progress !
I hope you'll be able to create nice games soon

By the way, I already managed to get 15puzzle to work on OS 3.1, just by saving it under an older OS... (3.0.1 IIRC)
(and my highscore is 72 moves)

Good luck with lua !

I agree with you jimbauwens, even if I would add some downsides to the TI-Nspire CX :
- Some bugs are quite annoying (like when the mouse appears, a weird square is displayed for a few seconds)
- The file explorer is really slow to load
- The text editor is way too slow too
- There is no official on-calc lua script editor

But the Nspire is still better than the prizm, IMHO
