SceUID vsh_graphics;
pspSdkReferThreadStatusByName("SCE_VSH_GRAPHICS",&vsh_graphics,0);
sceKernelSuspendThread(vsh_graphics);

Try that. If not...well, dig through the docs. They're REALLY helpful.

Yup, that worked well, but for future reference... what documents?

whats the svn for oslib ? or how do i go about installing it ?

Quick Google search threw this up, don't blame me if it doesn't work though as I already have it installed...

svn co https://ro-oslib.svn.sourceforge.net/svnroot/ro-oslib/trunk oslib

isnt that the svn for pc useage not psp ?

No idea, as I said I didn't install, all I did was a google search, but honestly, for something like OSLib, I'd suggest doing a google search there are plenty of places you can find it (even right here on QJ you can find a download).

I've been trying to get a bit of GU code to work in the XMB for the past... well too long, and I've whittled it down to something in my InitGU, and I was just wondering if theres anything I specifically shouldn't use in the VSH.

Just as a quick note, before I load my GU stuff I suspend the SCE_VSH_GRAPHICS thread, it only crashes when I resume the thread again. If I don't suspend the thread it crashes as soon as I load the GU code.

If its not possible to do it this way, is there any way I can stop a module, and then start it again, and if that was possible, would stopping the scePaf_Module and starting it again sort out these problems?

I'd keep trying different things myself, but my eyes have become a blur

Thanks

Look at the DSX source, it shows how to set up the GU for the VSH.

[xGriffinx]

How would I find out how much space is left in the ms?



edit

Another question...Shouldn't this in theory delete a filesystem? Why is it freezing on me?

void build_path(char *output, const char *root, const char *path, int append)
{
	while(*root != 0)
	{
		*output++ = *root++;
	}

	if(*(root-1) != '/')
	{
		*output++ = '/';
	}

	while(*path != 0)
	{
		*output++ = *path++;
	}
	if(append)
		*output++ = '/';

	*output++ = 0;
}

void delete_filesystem(const char *root)
{
	int dfd;
	char next_root[256];

	dfd = sceIoDopen(root);

	if (dfd > 0)
	{
		SceIoDirent dir;

		while (sceIoDread(dfd, &dir) > 0)
		{
			if (dir.d_stat.st_attr & FIO_SO_IFDIR)
			{
				if (dir.d_name[0] != '.')
				{
					build_path(next_root, root, dir.d_name, 1);
					delete_filesystem(next_root);
				}
			}
			else
			{
				char pathh[256];
				sprintf(pathh, "%s/%s", root, dir.d_name);
				sceIoRemove(pathh);
			}
		}
	}

	sceIoDclose(dfd);
	sceIoRmdir(root);
}

Why isn't it working?

If you would LEARN from the SDK samples instead of copy and pasting you'd learn why. Take sometime to look over it and see how it works and it'll be quite obvious ;)

No need for the Web, the manual sits on your computer when you install the SDK anyway.

(Posted since QJ was complaining I haven't posted for a few weeks... )

I don't actually have that, but I guess its because I can't install any of the things like everyone else (dialup user), so instead brethren burns everything I need to a DVD

Sorry to pester, but why dial up? Broadband is now low as $20 or so am onth - are you in a suburb or something?

By the way - They aren't that big of packages - 56kb won take long to get most libraries (except lua... that one is a beast)

Look at the DSX source, it shows how to set up the GU for the VSH.

I've looked at the source, but I think I have an incomplete source because I can't find anything helpful, I've downloaded from a couple of places and got the same each time... you could like me to somewhere that has the entire source?

I've also narrowed down the crash to this line of code

sceGuDispBuffer( SCR_WIDTH, SCR_HEIGHT, (void*)0x88000, BUF_WIDTH);

but my knowledge on GU is about as limited as a mules, so I'm not sure what I can change the values to for it to work safely.

A rhortical question, but do you think I want to be on dialup? Unfortunatly there is no broadband on the street I live (yet around the corner they can get it), and no, I live in a large community, so there really is no valid reasons to not have broadband wire to my house .

Downloading each library would be quick, but downloading them as a whole is pritty darn slow, when your download speed is lucky to ever reach 4kb/s.

Do you live in London, if so what part ?

i had the same sort of trouble ...

[myschoo]

hello ppl, can anyone help:

i set my app to kernel mode, but then i cant use stdio.h ... does anyone know solution... ?

[Insert_Witty_Name]

There's no reason you can't use stdio.h with kernel mode.

[myschoo]

mmm strange...

in main:

#include <stdio.h>

PSP_MODULE_INFO("blah",0x 1000,1,1);

using some file functions

in makefile:

USE_KERNEL_LIBC = 1
USE_KERNEL_LIBS = 1



and when i compile i get error undefined reference (or something similar) to all my file functions

[Insert_Witty_Name]

Remove the USE_KERNEL_* from the Makefile.

[myschoo]

is there a special rule when making prx in kernel? because the it wont react :/ but it compiles without errors... o_O

Try to make a deal with someone that could give you WLAN access until you get broadband over there? :)

[Auraomega]

Supprisingly theres no-one around here that actually uses a wireless network (even if there was I doubt they'd let me use it)... otherwise I would have been using their connection a long time ago (I would pay if available, but seeing as its not I'd do the next best thing...).

[Raphael]

Remove the USE_KERNEL_* from the Makefile.

Only the USE_KERNEL_LIBC :P
Else the kernel mode prx won't work in anything > 3.40

I'm making a sidescroller.

How would I set a jumping/walking speed?

(If I set a speed to walking, I wouldnt need to use lastpad...right?)

EDIT:

I think if I just make a varible, and make it go to a certain number, then move the charecter...(then reset the varible), it should work..

Lol, anyone understand that?

i would do something like

//declare all ours values first
int movespeed = 2;
float maxspeed = 10;
float xspeed, yspeed, friction;
xspeed = yspeed = 0.0f;
friction = .98f;


bool onGround = false;
//done declaring

//start processing run
if(right button pressed)
{
       xspeed += (float)movespeed;
}
if(left button pressed)
{
       xspeed -= (float)movespeed;
}
if(xspeed > maxspeed){xspeed = maxspeed;}
if(xspeed < -maxspeed){xspeed = -maxspeed;}
xspeed *= friction;

playerXposition += xspeed;
//done with run

if(onGround) //onGround can be set to true when there is a collision with the floor
{
    if(jump button pressed)
    {
         //do the same as with the xspeed but instead of friction u can subtract gravity
         onGround = false;
     }
}

of course u would have to add stuff, thats just a basic start i guess

[brethren]

i'm using psplink for the first time and i'm wondering if theres a command that you type in pcterm to start the vsh so i can look at what modules are loaded and basically just have a look round

btw i'm on 3.52 m33
