Post your Nspire routines here!

[bwang]

Are you supposed to be able to use floats as arguments to the sprite routine?

No.
@apcalc: Post your modified scrollScreen().

[apcalc]

bwang, that was the problem.  I had SCREEN_BYTES_SIZE+bytesOffset, which probably made it larger that it could handle.  Thank you so much for your help, I feel so stupid when it is a simple error like this. You might want to modify the utils.h/.c header to include functions for scrolling the screen up and down.  Here are my (hopefully working ) modified versions:

Code: Select All | Copy To Clipboard

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

void scrollScreenDown(char* scrbuf, char* tmpbuf, int lines) {   int bytesOffset = 160 * lines;   int cpysize = SCREEN_BYTES_SIZE - bytesOffset;   memcpy(tmpbuf, scrbuf - bytesOffset, cpysize);   memcpy(scrbuf, tmpbuf, cpysize);   memset(scrbuf + cpysize, 0xFF, bytesOffset); } void scrollScreenUp(char* scrbuf, char* tmpbuf, int lines) {   int bytesOffset = 160 * lines;   int cpysize = SCREEN_BYTES_SIZE - bytesOffset;   memcpy(tmpbuf, scrbuf + bytesOffset, cpysize);   memcpy(scrbuf, tmpbuf, cpysize);   memset(scrbuf + cpysize, 0xFF, bytesOffset); } [\code]

Glad to hear its working
I should probably move the scroll functions to graphics.h.

[DJ Omnimaga]

Glad it's working. I wish you good luck in your projects, if any (Starcraft Nspire... j/k )

We really need some documentation for these functions. I've started on it, and will post it when I'm done.

[t0xic_kitt3n]

How do you convert an integer to a string? I wanted to display the score in a dialog box upon exiting my game.

Also, the documentation is almost complete for utils.h, except for fade, scrollscreen, and WAIT. What do all the arguments do in these functions?

[calc84maniac]

Hmm, to convert an integer to a string, don't you do sprintf(string_ptr,"%i",score)

[t0xic_kitt3n]

Unfortunately, sprintf hasn't been written yet. There was another, simpler function, itoa, but it depends on this standard library function.

[calc84maniac]

I thought sprintf is part of the OS, and we are able to use it. Was I mistaken?

[bwang]

sprintf is part of the OS (at least it's defined in os.h).

scrollScreen() arguments:

Code: Select All | Copy To Clipboard

1 2	scrollScreen(char* scrbuf, char* tmpbuf, int lines)

Scroll the screen buffer scrbuf up lines rows. tmpbuf is a temporary buffer of the same size as scrbuf used by the routine internally.

[t0xic_kitt3n]

I never thought of looking there for sprintf. Thanks!

Also, at least on windows, the windows and linux makeTNS binaries can coexist peacefully, and I have a hunch it will be the same on linux, though someone should confirm it.

[bwang]

I updated the first post with a better graphics.h.

[apcalc]

I found a small error in common.h.

The "?" key, named "KEY_NSPIRE_?" causes an error when compiling because of the ?.

I have attached a fixed version with this key named "KEY_NSPIRE_QUES"

[bwang]

Fixed in the first post Thanks for the bugfix!
Can someone verify whether the Linux and Windows versions of the tools can coexist in the same directory? That way I can merge the two skeletons.

[t0xic_kitt3n]

I already said they can coexist on windows in a previous post here.
