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: Select all

// this code created from a modified fontm.c file
#include "gsKit.h"
#include "dmaKit.h"
#include "malloc.h"
 
int main&#40;void&#41;
&#123;
        u64 White,BlackFont;
        GSGLOBAL *gsGlobal = gsKit_init_global&#40;GS_MODE_NTSC&#41;;
 
        GSFONT *gsFont = gsKit_init_font&#40;GSKIT_FTYPE_FONTM, NULL&#41;;
 
        dmaKit_init&#40;D_CTRL_RELE_OFF,D_CTRL_MFD_OFF, D_CTRL_STS_UNSPEC,
                    D_CTRL_STD_OFF, D_CTRL_RCYC_8&#41;;
 
        // Initialize the DMAC
        dmaKit_chan_init&#40;DMA_CHANNEL_GIF&#41;;
        dmaKit_chan_init&#40;DMA_CHANNEL_FROMSPR&#41;;
        dmaKit_chan_init&#40;DMA_CHANNEL_TOSPR&#41;;

        White = GS_SETREG_RGBAQ&#40;0xFF,0xFF,0xFF,0x00,0x00&#41;;
        BlackFont = GS_SETREG_RGBAQ&#40;0x00,0x00,0x00,0x80,0x00&#41;;

        gsGlobal->PrimAlphaEnable = GS_SETTING_ON;
        gsKit_init_screen&#40;gsGlobal&#41;;
        gsKit_font_upload&#40;gsGlobal, gsFont&#41;;
        gsFont->FontM_Spacing = 0.95f;
 
        gsKit_mode_switch&#40;gsGlobal, GS_ONESHOT&#41;;
        int x=0;
        char tempstr&#91;25&#93;;
        while&#40;1&#41;
        &#123;
                gsKit_clear&#40;gsGlobal, White&#41;;
                sprintf&#40;tempstr, "test &#58; %i", x&#41;;
                gsKit_font_print_scaled&#40;gsGlobal, gsFont, 50, 50, 3.0f, 2.f, BlackFont, tempstr&#41;;
                gsKit_sync_flip&#40;gsGlobal&#41;;
                gsKit_queue_exec&#40;gsGlobal&#41;;
                // creates a delay, so the bug can be seen
                double i=0;while&#40;i<100000&#41;i+=.1;
                x++;
                if &#40;x==10000&#41;
                        x=0;
        &#125;
        
        return 0;
&#125;

Ewww... Thats ugly... No reason to do that crap... If you need a delay, do something like

Code: Select all

for&#40;i=0;i<60;i++&#41;
   VSync&#40;&#41;;

(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.
