thats the tutorial i followed, and i changed some stuff in the main (just made it 2d)

I was just going to start in C++, but this is the reason i never do, i always have problems compiling.

PS i named the dodads joan to see if it was changing anything (which it wasnt)
i might add also before i even changed anything, it wouldnt make a new eboot.

With that makefile it didn't compile an eboot?
Quite odd.
But why did you add all that stuff at the end?
like run: scekxploit and all that stuff?

Download the source/binary files from the tutorial and compile that.
If an eboot compiles then there's something wrong on your end.
If it doesn't, then the tutorial is wrong.

[dracule]

i didnt add any of that stuff at the end, i dontloaded the source and binary and ran make and it didnt work.
-= Double Post =-
the one you listed doesnt work either.

Im new to C so go easy on me :) Can you change the color and/or change the position of the text? thanks

[SWE_PsYcHo]

I need to rotate my screen for an app iam creating cause everrything needs to be upsidedown the text the images.... EVERYTHING . how do i do that with C ?

[Insert_Witty_Name]

In your VIEW matrix call sceGumRotateY(GU_PI);

[SWE_PsYcHo]

well iam really really novice so: huh?

[hallo007]

also I would suggest reading up on c file IO, if you already have do again. If you knew it well enough something as simple as copying a file should be no problem.

but the prob is I CANT COPY FROM ms0:/ TO ms0:/
godam thats already the fift time i say that , i can copy to flash but not ms0:/ to ms0:/

[dracule]

is there perhaps just a command i can use to make an eboot, because this is really annoying not being able to make an eboot.

[yaustar]

What error messages are you getting if any? Do you get a new elf file?

You should be able to. If not, copy ms0:/ to memory then memory to ms0:/. Simple.

In your VIEW matrix call sceGumRotateY(GU_PI);

Wouldn't it be the Z axis?

[dracule]

i get a new elf file, but no eboot. i already posted my makefile and main

[yaustar]

If you look in the build.mak file, it shows you how it makes the eboot. You can easily write a batch file to do the same.

I do suggest you read up on all of the six tutorials that www.psp-programming.com has. (well the six basic ones, it has fileio tuts, PSPGU tuts, etc.)

Enjoy C. :)

I wouldn't. Those tutorials are for learning how to program for the PSP, not learning C or C++. Go here: http://www.cprogramming.com/tutorial.html

[MasterChief117]

i'm dling the psptoolchain and its been stuck at "Logging in as anonymous ... " for 20 mins
on try 7 now. can i change the dling site

[PSPduh]

I wouldn't. Those tutorials are for learning how to program for the PSP, not learning C or C++. Go here: http://www.cprogramming.com/tutorial.html

Well I would assume he was talking about the PSP as this is the PSP development forum.

Alright, thanks guys!
Edit, also, very impressive Portfolio there Yaustar

I was wondering how to make a machine gun for a scrolling shooter. I have run into a problem because i can only display one bullet on the screen at once because when i try to shoot another, the variables are reset for the first one.

Main Loop:

int main() {
    char bullet_buffer[100];
    Image* bullet;
    
    int travel_x;
    int travel_y; 
    
    pspDebugScreenInit();
    SetupCallbacks();
    initGraphics();
    
    SceCtrlData pad;
    
    sprintf(bullet_buffer, "bullet.png");
    bullet = loadImage(bullet_buffer);
    
    while(1) {
             sceCtrlReadBufferPositive(&pad, 1);
             
             clearScreen(0);
             blitAlphaImageToScreen(0, 0, 5, 20, bullet, travel_x, travel_y);

             if(pad.Buttons & PSP_CTRL_CROSS) {
                            travel_y = 260;
                            blitAlphaImageToScreen(0, 0, 5, 20, bullet, travel_x, travel_y);
             }
             travel_x = 240;
             travel_y -= 5;
             
             flipScreen();
    }
    sceKernelSleepThread();
    return 0;
}

anyone? i left all night, but it didn't download 24 tries

[1337PSPer]

i remember when i was seting up toolchain i had to go find mirors for half the files because they wern't there maybe you will to or you can try my toolchain.sh file http://rapidshare.com/files/12649221/toolchain.sh.html

[MasterChief117]

thnx i'll tell you if it worked

i didn't work.....

[hallo007]

is there a way to use a bin2c file

static unsigned int size_background = 74112;
static unsigned char background[] __attribute__((aligned(16))) = {
	0x42, 0x4d, 0x20, 0x18, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x36, 0x00, 0x00, 0x00, 0x28, 0x00, 
.............................

as an .c file , so it dont need to compill always ( i have some files of 100 000 lines and that takes a moment;))

I was wondering how to make a machine gun for a scrolling shooter. I have run into a problem because i can only display one bullet on the screen at once because when i try to shoot another, the variables are reset for the first one.

If you want more than one bullet at a time, you also need more then one variable (pair). So use an array of variables to store the bullets positions.
You'll also need a way to decide whether a variable in the array is already used, so you'll end up with three variables per bullet (x,y,active/used).

s there a way to use a bin2c file
Code:

static unsigned int size_background = 74112; static unsigned char background[] __attribute__((aligned(16))) = { 0x42, 0x4d, 0x20, 0x18, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x36, 0x00, 0x00, 0x00, 0x28, 0x00, .............................

as an .c file , so it dont need to compill always ( i have some files of 100 000 lines and that takes a moment)

That already IS a .c file, so I don't know what you're asking.

[hallo007]

no it's an .h file , because if you do it with .c it will give an error in cygwin
(impledict declaration of....)

Huh???!??

Im kinda not understanding what you are saying :P ..

Make sure u add

in main.c
#include "yourfile.c"


In the makefile

TARGET = Hi
OBJS = main.c yourfile.c




I dont understand what you were saying so i hope that helped :P
