Okay, I need some help with something. I need to get a list of files in a directory. I've found how do it using sceIoDopen and so on, but that requires the path to that directory to be hard-coded. For example, I might expect the directory to be in ms0:/PSP/GAME/blah/huh/, but the user might have placed the eboot in GAME150, so it would fail. For normal file reading, I've used the f-something functions (fopen, fread etc.) instead of the SceIo* functions, so I can use relative paths. But how do I do this for finding the files in a directory?

Since you're allready using the c i/o functions why not use them for dir listing too ?
aren't the sce file i/o functions actually wrapper for the c file i/o?
anyway it works just fine with the c file i/o.

to determine the executable path you can analyse the argv command, tho i'm pretty sure this will only get you the exe name

Okay, I am trying to make a little game but i keep getting an error..

Not every error happens in main ;)
Unless you make the 2 global or advance to a better coding style you keep getting this error
=> read up on global variables

Nope, it gives you the full path of the PBP.

(main function code)

int main(void) {
    pspDebugScreenInit();
    SetupCallbacks();
    SceCtrlData pad;

    int ok = 1;
    int x = 100;
    int y = 100;
    int width = 50;
    int height = 50;

    Color red = RGB(0, 255, 0);
    Image* Background;
    Background = loadImage("./Images/Background.png");

    while(1) {
	sceCtrlReadBufferPositive(&pad, 1);

	blitAlphaImageToScreen(0, 0 , 480, 272, Background, 0, 0);

	// move square left
      if(pad.Buttons & PSP_CTRL_SQUARE) {
	x = x--;
      }

	// move square right
      if(pad.Buttons & PSP_CTRL_CIRCLE) {
	x = x++;
      }

	// move square up
      if(pad.Buttons & PSP_CTRL_TRIANGLE) {
	y = y--;
      }

	// move square down
      if(pad.Buttons & PSP_CTRL_CROSS) {
	y = y++;
      }


	// draw our little square!
      if(ok >= 1){
	fillScreenRect(red, x, y, width, height);
      }

	sceDisplayWaitVblankStart();
	flipScreen();

    }	
    sceKernelSleepThread();
    return 0;
}

Just to make sure....

Your including pspctrl to your source code right?

@BigSanFrey: Why are you trying to access pad and y in your CallbackThread function?

where? :s

Ok, im trying to make a 2d tile engine, but the problem is its not loading the tiles to the correctly to the array, here is my full main.c,
http://pastebin.com/m35b3bb94

the error is in the loading function, and im not sure how to go to the next char when reading.

Have you got jpeg installed????

If not...

svn checkout svn://svn.ps2dev.org/psp/trunk/jpeg
cd jpeg
make
make install

[BigSanFrey]

yep, i installed jpeg :s

[placo23]

yep, i installed jpeg :s

And you still have the same?

What's in ur code?

Are you on Linux? I've just tested this on my windows box, and it worked straight away, but when I tested the same code from my Linux Ubuntu box, i've had the same error, but instead of being with the jpeg, I got it from png. Though I have it properly installed

Cheers

[BigSanFrey]

yep, im on Ubuntu !

[placo23]

yep, im on Ubuntu !

Same here!!!!

[Archaemic]

You probably installed libjpeg from apt, yes? Well, if so, you installed it wrong. You need to do exactly what was specified on the previous page. Including make install. If you don't, it won't show up. If make install gives you errors, do sudo make install.

[Auraomega]

I'm having a problem adding 2 functions to an app, I want to launch in different kernels, so I've been using the SDK from the Hen C, but I also want to add the option to use the NoUMD for the newer firmwares, which the library included does not allow.

I've tried using the newest library (from the 3.71 SDK), but this doesn't have the former function of changing loading kernels, I've tried adding both libraries to my app, but I get a string of errors, so my question is, is there another library that has both of these options on, and if not, is there any way I can link both libraries into the app without conflict?

Thanks
-Aura

[BigSanFrey]

i did:
svn checkout svn://svn.pspdev.org/psp/trunk/jpeg
sudo ./configure
sudo make
sudo make install

same error still :s

[Archaemic]

Delete it, redownload it and DO NOT run configure. The makefile is already prepared.

How would you compile a program made in OSLib for use on a PC?

It's missing out an include because of that error, that could be the cause to alot of the problems. Check the graphics.h file.

Ok, im trying to make a 2d tile engine, but the problem is its not loading the tiles to the correctly to the array, here is my full main.c,
http://pastebin.com/m35b3bb94

the error is in the loading function, and im not sure how to go to the next char when reading.

Alright, i know what i half to do, i have to read the text file and put each character into the 2d array, but how would i do this?

Alright, i know what i half to do, i have to read the text file and put each character into the 2d array, but how would i do this?

Assuming the text file starts with 2 integers containing the x and y size of the map, this should work;

FILE *fp = fopen( "file", "rb" ); // open the file
unsigned int sizex, sizey, i;
char **map; // put the map data in this
fread( &sizex, sizeof(int), 1, fp ); // read the x size of the map into sizex
fread( &sizey, sizeof(int), 1, fp ); // same with y
map = (char**) malloc( sizeof(char*) * sizex ); // allocate memory
for( i = 0; i < sizex; i++ )
{
   map[i] = (char*) malloc( sizeof(char) * sizey );
}
for( i = 0; i < sizex*sizey; i++ )
{
    map[i/sizey][i%sizey] = fgetc( fp ); // read the data
}

i reformatted my PC but I backed up my whole c:\cygwin directory. ive copied it all back over but now when I run cygwin i get

bash-3.2$

in the command propt window. what do i need to do to get cygwin up and running again

[BlackShark]

how would the text file layout be? (spaces? no spaces? can i use char's other than numbers? if so, how would i blit them?
