C/C++ Programming Help Thread

[SuperBatXS]

@TMNT if mine is that easy then can you plz give me an answer this is the help thread

Lol, i was referring to my own problem earlier.

I would also like help on this. I tried using it, and it just crashed. So then I manually added the function stubs for it (properly, mind you), and the functions didnt do anything. So yeah, help?

Yea, i thought i had those working, but it turned out that i was on 1.5 (doesn't take long to downgrade or upgrade). Then i upgraded to 3.10 oe, and used the different functions for it and even tried the same one's. Neither of them worked, so yea, i could use help in this again. No one seemed to have answered my question (now youresam's as well).

[seenit]

o....ok

[youresam]

In case anyone cares...

STUB_START "sceDisplay",0x00090005,0x00010005 
  STUB_FUNC 0x31c4baa8,sceDisplaySetBrightness 
STUB_END

[BlackShark]

this should be a rather simple question to answer (and yet I searched and didn't find much) but..

how do i simply print out a function? (Using graphics.h), im trying to use...

printTextScreen(430, 5, "Time Left:%d", Msec, red);

but to no avail, Thanks for your time

[Insert_Witty_Name]

1. printTextScreen doesn't do formatted printing like printf does. sprintf it to a char buffer first.
2. I'm assuming Msec is a function that returns a value, in that case do Msec().

i seem to have **** up my cygwin, it doesnt have any of the commands, like ls or make or wget anymore. so i am going to uninstall and reinstall. but how do i uninstall? should i just delete the folder? there is no entry in add or remove programs.

[seenit]

thats what i did after i messed up the first time
-= Double Post =-
also what does the % sign do in codeing? i've seen it several times but never understood what it does
-= Double Post =-
as an example from another thread(you should know it)

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
	for(int c(0); c <= 100; ++c)
	{
		if (((c % 5) == 0) && ((c % 3) == 0))
			cout << "FizzBuzz\n";
		else 
			if ((c % 5) == 0)
				cout << "Buzz\n";
			else
				if ((c % 3) == 0)
					cout << "Fizz\n";
				else 
					cout << c << endl;
	}
	while(!kbhit());
	return 0;
}

so you can see what i'm talking about

[youresam]

% is modulate, returns whats left after a number divides into another evenly.

[seenit]

o ok i see now ty

[Insert_Witty_Name]

I've heard it called Mod, Modulus, Modulo or Modular - but never Modulate, though that might just be me...

Those words will help with your Google search though ;)

[Raphael]

Well, the common term is modulo which is an ablative form of the latin "modulus". Mod is used as short form and in mathematics as notation for the operator.
Modular and modulate are different things though ;)

1. printTextScreen doesn't do formatted printing like printf does. sprintf it to a char buffer first.
2. I'm assuming Msec is a function that returns a value, in that case do Msec().

no its an integer.

[Insert_Witty_Name]

Still, my first point stands.

[dracule]

can anyone suggest how to uninstall cygwin. i just want to delete the folder, but sometimes that screws up reinstallation

[seenit]

@dracule never had that prob anyways i have a question:

i'm trying to make my function to write in 3d and i'm wondering instead of using:

sprintf(print,"test %d",number);
then calling the function:
printing(-10,0,0,print);

if when i do my function if i could call it like:
void printing(float z_distance,float x,float y,sprintf(char *text,char *texts))
instead of:
void printing(float z_distance,float x,float y,char *text)

that would make it easier instead of having to declare sprintf(print,"test") every time before declaring my print jw if it is possible thanks in advance

[Insert_Witty_Name]

Look at stdarg.h and the va_* and vsn functions.

It's not hard to add printf style formatting to functions.

[seenit]

thats what i was asking earlier but never got a straight answer could you help me with getting my function to read format texting?

QFE?

i did a search for that lib but i never found it which was odd

i've been busy creating a proper version check; but i am not able the succeed
this is my code; (version check-part only)

int Startup(void)
{

    if(sceKernelDevkitVersion() == 0x02070110)
    {
        printf("\n");
        printf("You're using firmware 2.71\n");
        printf("For safety reasons you can't use this program\n");
        printf("Please Upgrade to 3.02 OE-A or higher\n");
        printf("Flash Magic Will exit in 10 seconds\n\n");
        wait(540);
        printf("          Bye Bye        \n");
        wait(60);
        sceKernelExitGame();
    }
    else if(sceKernelDevkitVersion() == 0x03000210)
    {
        printf("\n");
        printf("You're using firmware 3.02 OE-X\n");
        printf("you will go to main menu now \n");
        wait(300);
        pspDebugScreenClear();
        menu();
            }
    else if(sceKernelDevkitVersion() == 0x03000310)
    {
        printf("\n");
        printf("You're using firmware 3.03 OE-X\n");
        printf("you will go to main menu now \n");
        wait(300);
        pspDebugScreenClear();
        menu();
    }
    else if(sceKernelDevkitVersion() == 0x03010110)
    {
        printf("\n");
        printf("You're using firmware 3.10 OE-A\n");
        printf("you will go to main menu in 5 seconds \n");
        wait(300);
        pspDebugScreenClear();
        menu();
    }
   else if(sceKernelDevkitVersion() == 0x03030010)
    {
        printf("\n");
        printf("You're using firmware 3.30\n");
        printf("This firmware is not supported yet");
        printf("So please wait for Flash Magic 2.00\n");
        printf("Flash Magic Will exit in 10 seconds\n");
        wait(540);
        printf("          Bye Bye        \n");
        wait(60);
        sceKernelExitGame();
    }
    else
    {
        printf("\n");
        printf("You're running a non supported firmware ,\n");
        printf("Only Firmware 3.02 OE, 3.03 OE and 3.10 OE \n");
        printf("are supported, please upgrade \n");
        printf("Flash Magic Will exit in 10 seconds\n\n");
        wait(540);
        printf("          Bye Bye        \n");
        wait(60);
        sceKernelExitGame();
    }
    return 0;
}

what is wrong with it? it always says: You're running a non supported firmware; so it can't read version check or it automaticly go to else {

and something else; how can i see the diffrents bitween 3.03 OE-A 3.03 OE-B and 3.03 OE-C ??

[hallo007]

i told you before , check the size of some prx'en

[Archaemic]

I recommend using a switch command:

switch (sceKernelDevkitVersion()) {
    case [value1]:
    ...
    break;
    case [value2]:
    ...
    break;
    ...
    case [valuen]:
    ...
    break;
    default: //if no match
    ...
    break;
}

Also, output the value of sceKernelDevkitVersion to see what you do get.

Question:
Using GU functions, how do you rotate a cube (3D) exactly 90 degrees so that it faces from one side to another?

[seenit]

sceGumRotateY(90*(PI/180.0f))
-= Double Post =-
convert degrees to radians with PI/180

[SuperBatXS]

sceGumRotateY(90*(PI/180.0f))
-= Double Post =-
convert degrees to radians with PI/180

Uh......lol i just recently started learning gu functions. I know how to rotate a cube, but i still don't get what you mean...

[seenit]

it rotates by radians not degrees so you need to convert your degrees into radians with PI/180

[SuperBatXS]

How? Could you give me an example? Btw, i am using the tutorial 6 on psp-programming. Thanks.

[seenit]

when you go to move/rotate your object:

{
ScePspFVector3 move = {xtrans,ytrans, ztrans};
sceGumTranslate( &move );
sceGumRotateY(90*(PI/180.0f));
}
that puts your object where it should then rotates it to 90 degrees
you use sceGumRotateY which rotates your object around the Y axis

[MrChaos]

Hey guys,

Anyone got any idea how to render something in a loop?
