C/C++ Programming Help Thread

I think he is refering to an int. You can either cast it straight to an int which will truncate the float value (e.g 5.9 will become 5) or round it and then cast it to an int.

[SG57]

Anti-QJ - a decimal is technically a float/double with infinite precision (pi, e, etc). Floats, doubles, long doubles, etc. have limited precision for obvious reasons. since some machines have no real use for incredibly high precision, there isnt hardware dedicated directly to it (the PSP for example, it can't handle doubles in hardware so they are handled in software, so you loose a little performance using doubles. The PSP isnt a graphing calculator after all :o

ok, thanx for teh help.

Hi, I just began programming on the psp, but I have a little problem. I have a script that loads a .png and plays a .mp3, but if I want to write text it goes under the png. I just want it above , so some1 knows how to do this??

[Xsjado7]

Since you said script im guessing your using LUA. Theres a LUA help thread a thread-or-so below this one for any help you may have. Anyway, in your main loop/where the text and images are printed have your text preint first and then the image.

Quick question about AI. Iv never worked with it and i really dont want to but i have to for my game otherwise it'll never see the light of day. All im gonna be doing is generating a random number between 0 and 1000 with the mersenne twister or whatever its called. From there i simply do a check to see what the random number is and also how far away the player is for example 200 pixels. Then, if the random number is > 500, stand still else move forward. Is that what simple AI is based around? Iv read Vaza's first tutorial on planning and stuff but i cant really be bothered reading the others seeing as though they're about a tic-tac-toe game and im making a 2d fighter. I just wanna know if im going the right way

This tutorial shows you how to make use of the printTextScreen function.

its a program with a background (2 png's) and a selection menu with some text. Someone knows what i'm doing wrong??

[yaustar]

What is the EXACT error and line number?

[michaelp]

I'm pretty sure you forgetting 1 or 2 closing braces somewhere. If you indented your code, you would know that.

[devos50]

it's in the last line, with the
}

Here is the error in cygwin:
main.c: in function 'main';
main.c:142: error: expected declaration or statement at the end of input;
make: *** [main.o] Error 1

someone knows how to solve it?

ok, I can compile it now, but when I want to start it on my psp, it won't run. My psp freezes and shut down. Where is the error?? I've looked again at the script but can't find it:o

ps: I found an error in the callback thread. There was a space, but I saw that while I was compiling and fixed it, so that isn't the error, and I'm sure I've copied the test.mp3 and gw.png and background.png in the EBOOT folders, and have all the necessary headers.

[Mirzab14]

I was looking at the 1.50 POC source code, and was wondering how I would go on about changing this:

	if (strcmp(dirname, "ms0:/PSP/GAME") == 0)
	{
		theuid = res;
	}

so it would read from ms0:/PSP/GAME150 instead of /GAME. I've tried changing the string to /GAME150 but it still reads everything from /GAME.

Anybody?

you also have to change both paths in the dread and dopen functions

int dopen_patch(const char *dirname)
{
    int res = sceIoDopen(dirname);

    if (strcmp(dirname, "ms0:/PSP/GAME150") == 0)
    {
        theuid = res;
    }

    return res;
}

int dread_patch(SceUID dfd, SceIoDirent *dir)
{
    char path[512];

    if (dfd != theuid)
        return sceIoDread(dfd, dir);

    while (1)
    {        
        int res = sceIoDread(dfd, dir);
            
        if (res <= 0)
            return res;

        snprintf(path, 512, "ms0:/PSP/GAME150/%s/EBOOT.PBP", dir->d_name);

        SceUID fd = sceIoOpen(path, PSP_O_RDONLY, 0777);

        if (fd > 0)
        {
            u32 signature;

            sceIoRead(fd, &signature, 4);
            sceIoClose(fd);

            if (signature == PBP_SIGNATURE)
                return res;
        }

Hint: What does sceKernelSleepThread do? Where is it being called?

Thanks, but still doesn't work. Maybe its something that can't be edited?

[Durka Durka Mahn]

I was wondering if anyone knows how to get the title of a PSP Game while using a PRX?

I'm wanting to make my own simple universal cheat device and I need the title for each game.

[Xsjado7]

Either find the address of it in memory or maybe read the param.sfo of the currently playing game

[Archaemic]

Yeah, read the PARAM.SFO. disc0:/PSP_GAME/PARAM.SFO is where it is for every PSP game.

[Durka Durka Mahn]

Thanks.
Do you know exactly where in the file it is located?

[Archaemic]

If I'm not mistaken, it varies. You'll have to parse some of the file to get exactly where in the file it's located.

[Insert_Witty_Name]

Check out the source for mksfo in the SDK.

[yaustar]

The compiler says there is no datatype of Color. Are you sure it is defined in the headers you have included? Normally it is a u32 IIRC. That will solve most of the errors.

[Moose]

I'm sorry but what is a u32 IIRC?

[yaustar]

u32 = Unsigned 32 bit integer. If you look in the PSP SDK, you will see a typedef in one of the headers like this:

typedef u32 unsigned int;

Or similar.

IIRC = If I Recall Correctly.

[Xsjado7]

with OSL you declare it like:

OSL_COLOR*
