Probablye due to the settings. They all need to be to 0 I think (contrast and stuff).

In case anyone wants to know how I got the source code (in Linux) :p
I opened his file with nspire_emu, and copied the source to the clipboard (of the device), and then use gcore to dump the memory of the entire nspire_emu process (fun).
Then I searched for some lua code and found the position in the dump. All I then did was copy and paste

(The built in memory dump function does not work for me)

Thank you for the code !
And yeah, I need to fix 2 or 3 things.

DJ_O :
~~I really don't understand that bug...~~ NVM, fixed
And I'll try to make cubes more diagonal when you turn. It shouldn't be hard, but It will decrease the framerate a bit.

Jonius7 :
Thanks for the screenshot !
But it looks kinda weird... The framerate is really low and the grey squares don't show up...

Anyway, I'm going to add the TNS document and Jonius7's screenshot to the first post.
Could someone tell me if the document works for OS>=3.0.2 ?

DJ Omnimaga · « **Reply #18 on:** October 19, 2011, 03:28:14 pm »

I acutally made a screenshot, but it's in AVI format and doesn't run at the original frame rate. It's still the exact same speed as the game, though.

Jonius7 · « **Reply #19 on:** October 19, 2011, 03:28:31 pm »

I'm going to update the screenshot quite soon:

DJ Omnimaga · « **Reply #20 on:** October 19, 2011, 03:32:33 pm »

I appended my avi to the previous post. It's 2.21 MB. On calc the game runs at about 20-25 FPS, but the video runs at 15.

Btw can Lua display rotated cubes? If not, then it might be best to forget about my screen rotation idea lol. Else, maybe you can cheat like in Squidgetx game and simply display sprites of squares and display alternate ones when they're far away or rotating?

Jonius7 · « **Reply #21 on:** October 19, 2011, 03:42:02 pm »

Also another thing that could be added. In the original cubefield and the TI-84 version shown earlier, it starts with a corridor made out of cubes that the player travels through before entering the cubefield. Could this be implemented in the Lua version so it's not so easy to die instantly?

PS: I've uploaded the moving screenshot above.

DJ_O :
The function gc:fillPolygon() could be used, it would be quite easy.
Thanks for the avi btw !

Jonius7 :
The corridor would be harder... Well, I would have to create levels instead of random cubes. But I could do this.
And your latest screenie is great ! Thanks !

Jonius7 · « **Reply #23 on:** October 19, 2011, 06:12:27 pm »

the corridor will only have to appear at certain times so from 0 - 150 score the corridor appears. Then maybe another one at 700 or something. You might have to extend where the black cubes come in from 1000 to maybe 1400. But the rest will be the same random cubes. I'm sure you can do this.

Yeah but can Lua actually display rotated polygons? If so, then that's epically awesome

gc:drawPoly({x1, y1, x2, y2, ... })
You can make your own rotation matrix, apply it and give the x, y couple result to drawPoly

Chockosta · « **Reply #27 on:** October 23, 2011, 07:31:18 am »

Update !

-Now when you turn, the cubes become diagonal.
-The bug which caused some blocks that are farther to appear on top of the closer ones is fixed.
-Before the speed increases, a "Speed Up!" sign appears.
-Between 2 "levels", there is a corridor made of cubes.

Should I keep my little square for the player or should I create a sprite ?

As usual, I've attached a TNS file which contains the code. Could someone please extract the code ?
Thanks !

Very smooth game

and ...

but wait... you did all that oncalc ?
(NO WAY ?)

if so, I definitely can do something for you .... ( ;-) )

Chockosta · « **Reply #29 on:** October 23, 2011, 07:40:46 am »

Thanks a lot !
And yes, I entirely did that on-calc. (Just love on-calc programming)

What can you do for me ?
