Is there an easy way to get the icon/background of a homebrew game (What you see on the xmb)? Is there a function in C that can accomplish this?

P.S. I just realized that it is possible (irshell does it), but now I need to find out how to do it in c.

See Slasher's thread here: http://forums.ps2dev.org/viewtopic.php?t=6124

My CYGWIN says ERROR: Make sure you have GNU 'make' installed. Any ideas?

How do i clear the screen to be red?

[Waterbottle]

How do i clear the screen to be red?

with graphics.c?

clearScreen(color);

[Moonchild]

with graphics.c?

clearScreen(color);

No, fillScreenRect(RGB(255, 0, 0), 0, 0, 480, 272);
The fillScreen doesn't actually clear it with the color you specified. Just have a look at the function, you'll see that the color parameter isn't used.

No, fillScreenRect(RGB(255, 0, 0), 0, 0, 480, 272);
The fillScreen doesn't actually clear it with the color you specified. Just have a look at the function, you'll see that the color parameter isn't used.

That is the slowest possible way of doing it and I would avoid it at all costs.
Yes the clearScreen() function in the graphics.c is missing a line.

sceGuClearColor(GU_RGBA(255, 0, 0, 255));
 sceGuClearDepth(0);
 sceGuClear(GU_COLOR_BUFFER_BIT|GU_DEPTH_BUFFER_BIT);

If you're not using graphics.c, or change the clearScreen() function to this if you are:

void clearScreen(Color color)
{
	if (!initialized) return;
	guStart();
	sceGuClearDepth(0);
	sceGuClearColor(color);
	sceGuClear(GU_COLOR_BUFFER_BIT|GU_DEPTH_BUFFER_BIT);
	sceGuFinish();
	sceGuSync(0, 0);
}

Hi,
I'm trying to get a little client/server-application running (whereas the PSP is the client). Therefor I'm using a codeexample I got from a german tutorial. Unfortunately the compiler tells me

main.c: In function 'main':
main.c:72: error: 'INADDR_NONE' undeclared (first use in this function)
main.c:72: error: (Each undeclared identifier is reported only once
main.c:72: error: for each function it appears in.)

Line 72 is "if ((addr = inet_addr( argv[1])) != INADDR_NONE) {" and the whole code (just ignore the german comments, I can remove them if they are annoying):

You need a blank line at the end of your code.

#define INADDR_NONE ((unsigned long) -1)

It works, I'll just trust you that this is the right value... however, thank you!

Thanks SG57 :) it worked! But it's tremedously small, do you have any idea how to enlarge it?

[SG57]

Bronx - Dont translate so far in the distance, change the -15 to -1, should work fine

psp - For one, you are using both debug console + gu and without properly setting the debug console framebuffer address to the gu's, itll flicker. To solve this, use the pre-made printTextScreen functions for printing, as well as remove the sceKernelSleepThread call since that make sthe current thread fall asleep stopping EVERYthing besides the homebutton from working (software wise). Oh and you need to flipScreen() at hte end of hte while(1) loop.

O.o, duh... I feel stupid, lol

Um can you give me an example of the printTextScreen(); function?

You need a semi-colon at the end of this line:

Should be:

char buffer[200];

but when i compile it keeps telling me `rn0 (undeclared)'

There are no booleans in C.

Can glTranslate() and glColor4f() take variables as arguements? I tried it so if blah was pressed a variable that held the number for red decreased or increased and I placed that variable in glColor4f's first arguement, but it didn't work... I also tried the same idea for the glTranslate and it als didn't work... :/

i changed it from

bool rn0 = 0;

to

int rn0 = 0;

and it still doesnt work so idk =\

What? Basic C knowledge would lead to you knowing you can pass a variable as an argument. You probaby dont know the values for colors...

0.0f = no intensity
1.0f = full intensity

that variable must be a float and can't go above 1.0 and vice versa with 0. I still dont quite get what you mean though, sorry


psp - Best way to 'replicate' a boolean in C is to:

#define true 1
#define false !true
#define bool int

You also could make an enumerator, but i find it best to do it all during hte pre-processing stage (or w/e its called, sorry ).

Or just rename main.c to main.cpp, and add -lstdc++ to the libs section in the makefile, and you can use the bool enumerator/data type.

No, I know rgba, and I did have it as a float. so I had this basically:

float red = 0.0;
float green = 0.0;
float blue = 0.0;

glColor4f(red, green, blue, particle[loop].life);

Then I altered the switch statement for the controls to say if blah was pressed those vars would increase or decrease. And it didn't work. And I did the same concept with the translate func but declared the vars as int, and that didn't work either.

Hi
I'm now trying to create a simple server (using windows), but if I use "Microsoft Visual C++ 2005 express" with the "Microsoft Platform SDK" (i installed the SDK just like it's written here), he always tells me

fatal error C1083: File (Include) cannot be opened: "winsock.h": No such file or directory

when I try to compile. Using Dev-C++ he gives me a list of errors like

[Linker error] undefined reference to `[email protected]'
[Linker error] undefined reference to `[email protected]'
[Linker error] undefined reference to `[email protected]'
[Linker error] undefined reference to `[email protected]'
[Linker error] undefined reference to `[email protected]'
and so on

Can anyone help me?

As SG57 already said, something such as:

typedef enum {FALSE = 0, TRUE = 1} bool;

will suffice.

Bronx - I still havent a clue, but some things to try... Try moving the glColor4f into the glBegin and glEnd, else try removing the texcoordinates that are mapped for some reason (?). I dont see a texture being binded, so i dunno.

[Bronx]

ok, Ill try it :) Thanks
