Bump,

Why can't I use nSDL_DrawString(SDL_Surface*, nSDL_Font*, int, int, char*, ...) on a non-CX calc, when the exact same code works on CX calcs ?

That's weird; has apparently been working fine for others and me.

Does the function return 0? What's the exact code you're using? Not just a problem with colors that are converted into 4-bit format and happen to have same value?

@hoffa ! <3

I tested your "coyote demo" uploaded on TI-planet, did you made a topic for it ?

Damn that's some really old stuff (the tile map game engine thing, renamed it to Owl later). I think I had a thread here before yeah, but nobody seemed to care and I couldn't bear the responsibility of maintenance (or something) so I just deleted everything (I think I have a backup somewhere though).

That demo was in Ndless, right? That was cool, but IIRC by then the GBC emulator had come out and people didn't seem to take on large RPGs or something.
In case you are wondering where I went, I left Omni back in 2015 to form CodeWalrus due to various reasons explained back then, but I stopped calc dev in 2016 and am now mostly active on the CW Discord server at https://discord.gg/cuZcfcF

Time flies and I'm now in the UK doing a BSc in Computer Science. It's soon been a year, but yeah Australia was pretty cool, met and traveled with a whole bunch of interesting people (and girls), camped like a hobo everywhere, did all sorts of work and it pretty much changed the direction of my life with the whole Koreans and Korea episode (long story short found myself in Korean flat in Melbourne, had an awesome experience, made good friends and met my Korean ex, started learning the language #YOLO, made lots of Korean friends at university in the UK, visited Korea in Easter and going back in summer for 3 months to Yonsei University to study and a month to work. Have been studying the language for 6 months now and will do my graduate studies there, if not more)

Oh hey ! It's been a while :D Nice to see you're still working on calc stuff ;D

I can't think of anything to add to nSDL for now. It always had what I wanted it to have.

I don't know if I'm doing it wrong or what, but nSDL forces the BPP to 8 on TI-Nspire non-CX calcs, even after I set the LCD to 16-bits mode. Is it that you're checking the BPP validity with is_cx or has_colors in SDL_SetVideoMode ? If so, you should consider reading bit 1 to 3 of 0xC000001C to check if the screen is correctly set to accept the provided BPP value.

Okay, so I have a pretty large sprite sheet (converted to NTI, of course). When I use the following code to get the sprites:
Code: [Select]
void draw_tile(SDL_Surface *tileset, long tile_num, int x, int y)
{
    SDL_Rect src_rect, screen_pos;
    src_rect.x = tile_num * 10 + 8;
    src_rect.y = tile_num / 30 * 10 + 119;
    src_rect.w = TILE_WIDTH;
    src_rect.h = TILE_HEIGHT;
    screen_pos.x = x * TILE_WIDTH;
    screen_pos.y = y * TILE_HEIGHT;
    SDL_BlitSurface(tileset, &src_rect, screen, &screen_pos);
}

Any sprite with an x or y value greater than 127 is not displayed. I looked at the official SDL_Rect struct definition, and those values should end up being 16 bit values, not 8 bit values. Is this a problem with the code or a problem with the library? I am using a monochrome Nspire CAS.
I am Bach.
