not sure if this is the right place to post, but here goes.
first off i really appreciate the work being put into gsKit, it is really nice to have.
anyways, the bugs i have found so far involve fontm support. first when using \n in a string the next line is always 26.0f, i think multiplying by scale would solve this problem maybe?
secondly, sometimes when using sprintf to put a number in a string, it instead displays a letter, like 4 shows a 'u'. i took some screenshots and also wrote a simple demo program to show what happens.
| Code: |
// this code created from a modified fontm.c file
#include "gsKit.h"
#include "dmaKit.h"
#include "malloc.h"
int main(void)
{
u64 White,BlackFont;
GSGLOBAL *gsGlobal = gsKit_init_global(GS_MODE_NTSC);
GSFONT *gsFont = gsKit_init_font(GSKIT_FTYPE_FONTM, NULL);
dmaKit_init(D_CTRL_RELE_OFF,D_CTRL_MFD_OFF, D_CTRL_STS_UNSPEC,
D_CTRL_STD_OFF, D_CTRL_RCYC_8);
// Initialize the DMAC
dmaKit_chan_init(DMA_CHANNEL_GIF);
dmaKit_chan_init(DMA_CHANNEL_FROMSPR);
dmaKit_chan_init(DMA_CHANNEL_TOSPR);
White = GS_SETREG_RGBAQ(0xFF,0xFF,0xFF,0x00,0x00);
BlackFont = GS_SETREG_RGBAQ(0x00,0x00,0x00,0x80,0x00);
gsGlobal->PrimAlphaEnable = GS_SETTING_ON;
gsKit_init_screen(gsGlobal);
gsKit_font_upload(gsGlobal, gsFont);
gsFont->FontM_Spacing = 0.95f;
gsKit_mode_switch(gsGlobal, GS_ONESHOT);
int x=0;
char tempstr[25];
while(1)
{
gsKit_clear(gsGlobal, White);
sprintf(tempstr, "test : %i", x);
gsKit_font_print_scaled(gsGlobal, gsFont, 50, 50, 3.0f, 2.f, BlackFont, tempstr);
gsKit_sync_flip(gsGlobal);
gsKit_queue_exec(gsGlobal);
// creates a delay, so the bug can be seen
double i=0;while(i<100000)i+=.1;
x++;
if (x==10000)
x=0;
}
return 0;
}

Ewww... Thats ugly... No reason to do that crap... If you need a delay, do something like
| Code: |
for(i=0;i<60;i++)
VSync();
|
(assuming VSync() is defined.. I have my own vsync call, there is probably one provided somewhere in gskit as well, or you could just draw it on both front and back buffers and do sync_flip)

| yeah i know...i use eetimers in my real program for making delays, this was just a rather quick hack to find the bug...which randomly vanishes from me. |

Re: sprintf
The first thing to do is to try and determine if it is sprintf() or gsKit_font_print_scaled() that is buggy. After doing the sprintf, printf the string, and check the console to see what is printed.

i tested that...its the gskit print function that is buggy..although i now think that it is somehting i am doing.
in the small game i am making, if i pause/unpause the screen the numbers are displayed properly. if i pause unpause again they go back to being messed up.
when i pause the game..i site in a loop, which occurs right after i have swapped my buffers..
gsKit_queue_exec(gsGlobal);
gsKit_sync_flip(gsGlobal);
while(pause)
handlekeys();//toggles pause when they press the pause button
i don't know how that makes a difference at all....but it seems to be something i am doing wrong. |

Yo!
Thanks for the problem report.
I'm pretty sure I know what the problem is, and I've done some things that should fix it.
I have a big(ish) commit going in sometime in the next couple days, please give it a run and let me know if it fixes the issue for you.

Get latest from gsKit SVN. The issue should be resolved now.
