ill pm you

Where is the example data?

1. Use the right headers:

#include <windows.h>
#include <iostream>
#include <cstdio>
#include <cstdlib>
#include <string>
#include <fstream>
#include <cstdlib>

2. Use example code that is given to you:

// Opens name

        {
            ifstream OpenFile("name.conn");

            if( !OpenFile )
            {
                cerr << "Error opening file" << endl;
                return -1;
            }

            string tempString = "";

            while ( OpenFile >> tempString )
            {
                name += tempString;
            }

        }

So can anyone help me out with my problem? I'd rather stay using pspctrl.h than change. Thanks

[Raphael]

Hey everyone, I was wondering if there's any alternative to PSP_CTRL so that it just records the initial press of a button and not you constantly holding it. Any help would be great, thanks

You asked for an alternative to pspCtrl, not on a way to do what you want with still using it :P But anyway, the solution is very easy and taking a look at the source of any engine that handles it would suffice.
Here's code from my current working code:

static SceCtrlData pad, oldPad;
static unsigned int pressed_buttons, released_buttons, held_buttons;

void update()
{
oldPad = pad;
sceCtrlPeekBufferPositive (&pad, 1);

held_buttons = pad.Buttons;
pressed_buttons = pad.Buttons & ~oldPad.Buttons;
released_buttons = ~pad.Buttons & oldPad.Buttons;
}


bool pressed( unsigned int buttons )
{
return ((pressed_buttons & buttons) == buttons);
}


bool released( unsigned int buttons )
{
return ((released_buttons & buttons) == buttons);
}


bool held( unsigned int buttons )
{
return ((held_buttons & buttons) == buttons);
}

[Xsjado7]

Lol, i meant i was wondering if there was an alternative to the function PSP_CTRL, not the lib. Anyways, thanks for that Raphael. I had a look through OSLib but couldnt find it

                name += tempString;
            }

        }

this works perfectly except, the name is repeated twice.


it comes out namename

its huge, i included #include </usr/include/sys/stat.h> because the tutorial said to !

[eldiablov]

You cant include something that isn't there. You may have to download the header and put it there.

[BigSanFrey]

where do i find the header? (im on ubuntu)

[Archaemic]

Try adding CFLAGS+=-I/usr/include in your makefile

Actually, that might not be a good idea. Remove the /usr/include/ from the include so it's just sys/stat.h

[BigSanFrey]

nope, that doesn't help:
game.c:5:43: error: /sys/stat.h: No such file or directory

[Blackbelttcon]

        {
            ifstream OpenFile("name.conn");

            if( !OpenFile )
            {
                cerr << "Error opening file" << endl;
                return -1;
            }

            string tempString = "";

            while ( OpenFile >> tempString )
            {
                name += tempString;
            }

        }

the variable name repeats twice in the text, like namename

how do i change that

[Archaemic]

nope, that doesn't help:

Remove the leading slash.

It doesn't. I checked the compiled code you gave. Check what is in your .conn files. Check your print output code. Debug and use breakpoints to see what values are being stored.

[Blackbelttcon]

the .conn files are fine, just one name, the debug was fine also just one value, and here is my input code ( i dont no what you mean by the print output code)

  {

    ofstream SaveFile("name.conn");

	SaveFile << name <<endl;
 	SaveFile.close();

   }

[BigSanFrey]

Remove the leading slash.

thanks that helped :)

[yaustar]

the .conn files are fine, just one name, the debug was fine also just one value, and here is my input code ( i dont no what you mean by the print output code)

  {

    ofstream SaveFile("name.conn");

	SaveFile << name <<endl;
 	SaveFile.close();

   }

If what you say is true then it is IMPOSSIBLE for it to output twice unless you are specifically doing it by:

cout << name << name << endl;

Without seeing your code again, a rough guess is that you are reading the file twice somewhere and appending the original string twice.

OR that you have a typo and reusing the same variable twice for two different .conn files.

Repost your current code PUBLICALLY here (and properly formatted).

sorry for not putting it in a spoiler it errored my firefox everytime i tryed to paste the code.

[Auraomega]

Just a quick question about PSPLink, I've upgraded to 3.52M33, and the shell isn't printing information back to me anymore, this has started to become an issue and I was wondering if there was a fix and/or if higher firmwares printed info on the shell again.

And I've been messing around with sceKernelLoadExec, and it appears that it won't work in 3.XX kernel, which is most likely to be the reason why I'm having problems, because my app runs in 3.XX, is there any way I can get sceKernelLoadExec to work in 3.XX without switching kernel? (I want to make this Slim friendly).

Thanks.
-Aura

[Raphael]

while ( OpenFile >> name)
{
name += name;
}

LOL, and you wonder why it prints the name twice?

@Auraomega: You need to use the release_oe build of PSPLink and put it in the game folder, running it in 3.xx kernel OR use the normal release build of PSPLink and put in the game150 folder.

[Blackbelttcon]

no all that does is takes the name variable from the text file, and makes it a variable to use for the program.


i could change that to

while ( OpenFile >> username)
{
username += name;
}
-= Double Post =-
but thanx though

[Raphael]

Are you serious about what you just said? Dude.... read the exact code that yaustar has given you, then look at what you really used. Now think about why your code will produce double output. Really think about it.
If you don't get it, read up on what the += operator does on strings here: http://www.cplusplus.com/reference/s...perator+=.html

If you still don't get it.... I'm sorry but then you are beyond help.

[Auraomega]

You need to use the release_oe build of PSPLink and put it in the game folder, running it in 3.xx kernel OR use the normal release build of PSPLink and put in the game150 folder.

Thats what I've been doing, I'm using the release_oe version, but I still get the same problem of nothing coming up on the shell. When I run in 1.50 kernel it works fine though.

Hey, sorry for all these questions i have been posting lately, I was just wondering how i would go about doing something with a 1/3 - 2/3 - 1/2 and so on chance. Would having a variable that counted up and down from, say, 1 to 300 and did something like:

if(variable > 200)
{
do code
}
if(variable < 200)
{
do other code
}

work the same/well enough. It's for my AI. Any help would be greatly appreciated, thanks

PSP_MODULE_INF should be PSP_MODULE_INFO

nvm i saw you got it to work

i highlighted the lines of the error in bold

any help appreciated

thanks

This may sound random but can somebody link me to chip 8 emulator source code that involves no sdl please ?

[Auraomega]

Is it possible to use sceKernelLoadExec in 3.XX, and if so can someone post an example as I can't get it to work. Also, I'm still seeing nothing in PSPLink, even though I'm running the PSPLink from release_oe, if anyone can link me to a compiled working version I'd be grateful.

Thanks.

Thats what I've been doing, I'm using the release_oe version, but I still get the same problem of nothing coming up on the shell. When I run in 1.50 kernel it works fine though.

-Aura

Then just use the normal release build and put it into the game150 folder.
