MSXgl – A new C game library for MSX

Thanks aoineko!
Well, even with it it doesn't seem to work in my code. I'm generating the header this way: wine $(tools)/MSXtk/bin/MSXimg.exe assets/ship_spr.png -name ship_spr -trans 0xff00ff -pal msx1 -size 16 16 -mode sprt -i16 0 0 1 1 -out assets/ship_spr.h || true

If I call directly VDP_LoadSpritePattern(src, index, 4); the order is wrong. That's why I wrote this other function:

void VDP_LoadSpritePattern16_fix(const u8* src, u8 index) {   
    u16 low = g_SpritePatternLow + 8*index;
    u8 offsets_src[] = {8*0, 8*2, 8*3, 8*1};
    u8 offsets_low[] = {8*0, 8*1, 8*3, 8*2};
    
    for(u8 i = 0; i < 4; i++) {
        VDP_WriteVRAM(src + offsets_src[i],
                      low + offsets_low[i],
                      g_SpritePatternHigh,
                      8);
    }
}

I'll investigate more, since there must be any detail I'm skipping. If the example you wrote works well, then I'm doing something different... I'll compare with the example.

For MSXimg there's only MSXimg.exe for Windows.
Although the source code is available, I couldn't compile it because the file "tchar.h" is not found in my system. Yes, I could find which is the package which provides that header, but I since I wanted to start my project ASAP, I just used wine for the moment.
To reach the last position at MSXDev'03 XD

I think you forgot the sprite color in your command Line
-i16 0 0 1 1 0xFFFFFF
With i16 (i=include) only the provided color will be exported.
With e16 (e=exclude) all the colors but the provided one will be exported.
It could seem complex but it's usefull to export multi layer sprites like in my Example sample or in my game Final Smash.

Happy birthday MSXgl!
The library have been officially released just 1 year ago.

A lot of things have changed since 1 year (multi-platform support, new audio format, optimization, new devices, etc.).

But there is one thing that hasn't changed, it's my game projects that don't progress much. ^^

Thanks ToriHino. If you see anything to improve, don't hesitate to tell me.
Beyond the fact that creating this library is fun for me, all this work will really make sense when MSXgl will have helped new MSX games or tools to be released. Hopefully in 2023.
