Re: Fonts aren't working...? I used 8x8 pixel rom font editor

My first instinctive thought is that you only provide 8 bytes per character as opposed to 16 as the graphics uses two bitplanes.
Try duplicating each byte and put it in direct succession of itself.

as in:

0x18, 0x3C, 0x3C, 0x18, 0x18, 0x00, 0x18, 0x18,    // Char 033 (!)
becomes
0x18, 0x18, 0x3C, 0x3C, 0x3C, 0x3C, 0x18, 0x18, 0x18, 0x18, 0x00, 0x00, 0x18, 0x18, 0x18, 0x18,    // Char 033 (!)
etc.

Not sure how GBDK formats its fonts, but I'd expect them to be just straightforward 16 bytes per tile as it seems to generate all 4 shades in the image you've linked.

IDEA! GUESS!

Maybe they're tiles!? What an unprofessional font editor... oh well.

Re: Fonts aren't working...? I used 8x8 pixel rom font editor

Well all graphics on the GB is made up by the same characters in VRAM (albeit you can reconfigure the order a bit)
So everything could be considered tiles essentially and the fonts in GBDK is no different.
The only thing that may differ is how you store it in ROM and/or modify the data before loading it into VRAM, and that might be what differs between the font editor you use and how GBDK handles its fonts.

So was the problem solved or not?

Re: Fonts aren't working...? I used 8x8 pixel rom font editor

Hey, I'm trying to set my own custom font so I'm interested on that point too.
I tried to duplicate each bytes as RoboTwo suggested, but the program won't compile, giving me an overflow.

Otherwise, from what I read on the documentation of GBDK, there's a way to specify that your font is using only 8 bytes per character (here : http://gbdk.sourceforge.net/doc/html/c0 … CTURE-TYPE) but I don't know how to set that.

I think the easiest way to pass the problem would be to code the font directly in asm as done for the exemple fonts, but how should I link that to my C code after?

I hadn't done a lot asm before so I'm not really good about it, so if you can help me that would be really nice.

Re: Fonts aren't working...? I used 8x8 pixel rom font editor

If you're getting an overflow error, try making the array const, i.e. const unsigned char font[];
That'll cut down on memory usage for the array. I usually also save tile sets and other large arrays in other memory banks to save space, but that's up to you.

Re: Fonts aren't working...? I used 8x8 pixel rom font editor

Okay, so now it compiled using a const array.

However, most characters seems to be messy. I took the font showed on the first post and duplicate some characters (for exemple, $ and %), for the other ones I filled with 0x00 which shouldn't be a problem.

If I try to print "$%", the result I have is the following :

Re: Fonts aren't working...? I used 8x8 pixel rom font editor

So I loaded some of this data up as tile data, and loaded the rom into BGB, and here's the data from the VRAM viewer:
https://i.imgur.com/IeQJKXj.png
I set tile 0 to $00, so it should've been blank. But it looks like this "font" is working, and is just slightly bigger than 2 letters per tile high. I can make out numbers/letters, etc. So, yeah, it'd look like gibberish normally unless GBDK has some special way of displaying it. I use assembly/RGBASM and don't have any experience with GBDK, so I wouldn't be much help there.

EDIT: Just wanted to clarify - just doubling up the bytes isn't working. It isn't 2 letters per tile. It's like ~2.1 letters per tile.

Okay, if you find how to solve the problem feel free to answer here. I think it could be really helpful.

Re: Fonts aren't working...? I used 8x8 pixel rom font editor

I haven't used the font library with GBDK before, but here's how I load fonts:

I have a const UBYTE array which defines the 8x8 pixels tiles of ASCII characters 0 through 127. If I have any special character tiles in my game that I want to use (e.g. button symbols), I'll load them into unused tiles, i.e. 1-31.

Code:

const UBYTE fontTiles[] =
{ 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, //0, null char
  0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,
  0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, //1, unused
  0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,
  0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, //2, unused
  0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,
    ...
  0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, //32, space
  0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,
  0x0C,0x0C,0x0C,0x0C,0x0C,0x0C,0x08,0x08, //33, !
  0x08,0x08,0x00,0x00,0x08,0x08,0x00,0x00,
  0x00,0x00,0x12,0x12,0x24,0x24,0x24,0x24, //34, "
  0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,
  0x00,0x00,0x12,0x12,0x3F,0x3F,0x12,0x12, //35, #
       ...
}

In my game, I load the font with

Code:

set_bkg_data(0,128,fontTiles);

Then when I want to print stuff, I use this custom print function:

Code:

void print(UBYTE x, UBYTE y, UBYTE *str, UBYTE len){
   set_bkg_tiles(x, y, len, 1, str);
}

I used have it use strlen(str), but that apparently isn't always reliable, so I hardcode the length of the string when I call it, e.g. for hello world, you'd have to call it like:

Code:

print(1,1,"Hello World",11);

This print function doesn't wrap around to new lines. And if you want to print numbers, you'd have to make a placeholder array and call sprintf(), e.g.

Code:

UBYTE placeholder[2]; //can hold 1 digit and a trailing null char
sprintf(placeholder, "%d", (UWORD)2+5);
print(1,1,"2+5=",4);
print(5,1,placeholder,1);

I'm currently trying to make this system better, but if using the font library doesn't work, here's an alternative.

Re: Fonts aren't working...? I used 8x8 pixel rom font editor

I unfortunately don't care enough about GBDK to learn it to solve this problem, sorry. I need to spend my time focusing on ASM.
The GBDK documentation is here: http://gbdk.sourceforge.net/doc/gbdk-doc.pdf
Per the font part of that, I'd check the font_struct to see if it's encoding the font in 8 bytes or 16 bytes (using bit 3 of the returned font_struct). AFAIK, it's doing compression on the tiles, and then decompressing them before loading them into VRAM, if that bit is set.
You could try using mprint_string() instead of printf(). Or try decompressing them yourself, using the data from the document I linked.
G'luck.

Re: Fonts aren't working...? I used 8x8 pixel rom font editor

Okay, so I'm bumping again this subject.

I decided to use the font via an asm file (made following the included ibmfixed.s).

Here's the file if you want to check it (nothing fancy) :

Code:

    .db 0b00000000
    .db 0b00000000

;end of file

Anyway, after that I made a simple program to load the font and print some text :

Code:

void main(void)
{
    font_t custom_font;
    
    font_init();
    
    custom_font = font_load(font_custom);  // 95 tiles
    
    mode(get_mode() | M_NO_SCROLL);
    
    font_set(custom_font);
    printf("Simple test:\n");
    printf("100 working?\n");
}

Then, I launch the resulting gb file and... here's the result :
http://www.plixup.com/pics_core3/14416368066144result_custom_font.png

It's a bit better that what we had previously, but it still has some display issues.
Do you know where would the problem be?

My guess would be that it comes from the compressing thing or I don't know, but I've set the font as 128 characters compressed (8 bytes for one character). According to the doc, it should expend automatically to 16 bytes.

I tried to load the tiles on BGB VRAM viewer, but it gives me the same result. So I think the problem comes from the compilation?

Re: Fonts aren't working...? I used 8x8 pixel rom font editor

if you make spaces between all the letter do you still have this problem

just wondering if its because the font is being squashed together

so like:
printf("H E L L O\nW O R L D")

Re: Fonts aren't working...? I used 8x8 pixel rom font editor

Still the same problem yes.

As you can see on the VRAM viewer, the tiles are saved in that form in the memory :

Okay, I don't know if double posting is forbidden here (if not, sorry).

I've finally been able to run my own font. I really don't know how, but anyway. I'll try to do a test with another font and if it does work again, I'll explain the method to do so.

Re: Fonts aren't working...? I used 8x8 pixel rom font editor

This could be 100% my ignorance showing, but in the ASM font file, you have:

Code:

 .globl font_load

Should that have been:

Code:

 .global font_load

?
No idea if that actually matters.
Barring that, it looks like something wacky on GBDK's decompression. Can't help, sorry.

Re: Fonts aren't working...? I used 8x8 pixel rom font editor

Well, no it doesn't change anything, and it happens that I finally don't need this line.
Anyway, I've made some others tests and it still work, so here's how to do this.

First, you'll have to make a .s file with the following datas :

Code:

    .area    _BASE

_your_font_name::    ; Name of your font
    .db 1+4        ; Correspond to the type of your font - here is a 128 bytes characters font, compressed (1bpp) - more informations : http://gbdk.sourceforge.net/doc/html/c0509.html
    .db 95        ; Number of unique characters in your font

; Encoding table - assign each ASCII character to one of your font character (if your A character is the second one, then you will have to put 0x01 for the 65th character
    .db 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00
    .db 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00
    .db 0x00,0x01,0x02,0x03,0x04,0x05,0x06,0x07,0x08,0x09,0x0A,0x0B,0x0C,0x0D,0x0E,0x0F
    .db 0x10,0x11,0x12,0x13,0x14,0x15,0x16,0x17,0x18,0x19,0x1A,0x1B,0x1C,0x1D,0x1E,0x1F
    .db 0x20,0x21,0x22,0x23,0x24,0x25,0x26,0x27,0x28,0x29,0x2A,0x2B,0x2C,0x2D,0x2E,0x2F
    .db 0x30,0x31,0x32,0x33,0x34,0x35,0x36,0x37,0x38,0x39,0x3A,0x3B,0x3C,0x3D,0x3E,0x3F
    .db 0x40,0x41,0x42,0x43,0x44,0x45,0x46,0x47,0x48,0x49,0x4A,0x4B,0x4C,0x4D,0x4E,0x4F
    .db 0x50,0x51,0x52,0x53,0x54,0x55,0x56,0x57,0x58,0x59,0x5A,0x5B,0x5C,0x5D,0x5E,0x00

; And now, you have to design each characters following this sequence (I've put only two for exemple)
;Character   (32)
    .db 0b00000000
    .db 0b00000000
    .db 0b00000000
    .db 0b00000000
    .db 0b00000000
    .db 0b00000000
    .db 0b00000000
    .db 0b00000000

;Character ! (33)
    .db 0b00000000
    .db 0b00011000
    .db 0b00011000
    .db 0b00011000
    .db 0b00011000
    .db 0b00011000
    .db 0b00000000
    .db 0b00011000

On this exemple, I'm using a compressed font, which mean that I each byte will represent one pixel (0 -> White, 1-> Black). If you want to use a 4-shaded font, you'll have to use 16 bytes for each characters and remove the "+4" on the font type.

In order to convert directly my font in bytes, I've made a simple program that will convert a plain PBM file (you can generate it using Paint.net for exemple) to a data file. If you want it, here it is : http://www.mediafire.com/download/6m2q0 … verter.exe
And here is what my PBM file looks like (here saved as .png, but you get the idea) : http://www.plixup.com/pics_core3/144178 … custom.png

Once your .s file is complete, move it to your project folder, and link it on the compiler (if you're using a make.bat - which I recommend - you can directly output your .gb file from .c and .s files - see compiler options if needed : http://gbdk.sourceforge.net/tools.html)

Now, in your c code, you can use your font by loading it with font_load(your_font_name).
However, the code can't compile yet. For this, you'll have to go on gbdk\include\gb, open the font.h file, and add your custom font to the list of default fonts :

Code:

/** The default fonts */
extern UINT8 font_spect[], font_italic[], font_ibm[], font_min[], your_font_name[];

And after that, everything should be working!
