Short question: are there dynamic arrays in C (not ++)? I mean can I declare an array like "myType myName[]" and later on add items like "myName[0] = 1; myName[1] = 2;" ?

No, unfortunately not. You have to do them yourself, or use a static array that holds the maximum number of elements you want to put into that array. Creating a dynamic array is not very hard though (using malloc/realloc).

Thank you. What library do I need for malloc/realloc? Is there a <stdlib.h> in PSPSDK? And is that the correct way of using them:

type name = malloc(ArraySize);
array = realloc(array, NewSize);

?

Yes, there is a stdlib.h, but you just need to include <malloc.h>, nothing more. And yes, that's the correct syntax to use.

Hm, I' getting errors:

Code:

---

    typedef struct
    {
        Image* iconHigh;
        Image* iconLow;
        char label[16];
        int x,y;
        int imgOffsetX;
    } MenuItem;


    typedef struct
    {
        Image* iconHigh;
        Image* iconLow;
        char label[16];
        int x,y;
        int imgOffsetX;
        MenuItem subMenu[2];
    } MainMenuItem;
   
    MainMenuItem mainMenu[5];

    mainMenu[0].subMenu = realloc(mainMenu[0].subMenu, 5);    // Line 139

---

Error:

Zitat:

---

main.c: In function 'main':
main.c:139: error: incompatible types in assignment

subMenu has to be a pointer if you want to malloc it (e.g. you can't allocate a struct/array with a static size).

ive had the same prob when i tried to make a mini shell and i asked every person and schearched every thread and i didnt find anything but you could try asking at pspdev.org (:

---

I was hoping someone here would know:(. I guess I'll try pspdev. If you find a way to do this PSP-Maniac, please let me know.

how do you port this (cout to printf)

Zitat:

---

cout<<"schrijf 2 getallen voor te vermenigvuldigen: ";
cin>>x>>y;
cin.ignore();
cout<<"het produkt van de 2 getallen is ";
cout<<x*y<<"\n";

---

i tested this , but it only prints text and dont execute x*y

Zitat:

---

printf("schrijf 2 getallen voor te vermenigvuldigen: ",x,y);
printf("\n");


printf("het produkt van de 2 getallen is ",x*y);

---

I don't quite get it. I tried various kinds of combinations between pointers and arrays. Eg.

Code:

---

    typedef struct
    {
        Image* iconHigh;
        Image* iconLow;
        char label[16];
        int x,y;
        int imgOffsetX;
        MenuItem subMenu;
        MenuItem *pSubMenu;
    } MainMenuItem;

    MainMenuItem mainMenu[5];

    mainMenu[0].pSubMenu = &mainMenu[0].subMenu;
    mainMenu[0].subMenu = realloc(mainMenu[0].pSubMenu, 5);

---

But this doesn't only look wierd, it really don't works. Can you give me an example of how to declare an array in the mainMenuStruct later on set its size / how to create an array of MainMenuItems with SubmenuArrays of different sizes in it ?

Here:

Code:

---

typedef struct
    {
        Image* iconHigh;
        Image* iconLow;
        char label[16];
        int x,y;
        int imgOffsetX;
    } MenuItem;


    typedef struct
    {
        Image* iconHigh;
        Image* iconLow;
        char label[16];
        int x,y;
        int imgOffsetX;
        MenuItem *subMenu;
    } MainMenuItem;
   
    MainMenuItem mainMenu[5];


//Allocation (should be in a function)
mainMenu[0].subMenu =(MenuItem *)malloc(5);

---

You then use it like this (example code):

Code:

---

strcpy(mainMenu[0].subMenu[0].label, "Test0");
mainMenu[0].subMenu[0].x = 0;
mainMenu[0].subMenu[0].y = 0;

---

To reallocate it you simply do this

Code:

---

mainMenu[0].subMenu = (MenuItem *)realloc(mainMenu[0].subMenu, 6*sizeof(MenuItem));

if youre using the graphics lib you can use

Code:

getPixelScreen(int x, int y)

I don't wanna go on you guy's nerves, but I'm having a wierd error; Same code as above

Code:

---

    typedef struct
    {
        Image* iconHigh;
        Image* iconLow;
        char label[16];
        int x,y;
        int imgOffsetX;
    } MenuItem;


    typedef struct
    {
        Image* iconHigh;
        Image* iconLow;
        char label[16];
        int x,y;
        int imgOffsetX;
        int maxMenuItems;
        MenuItem *subMenu;
    } MainMenuItem;
   
    MainMenuItem mainMenu[5];

    mainMenu[0].subMenu =(MenuItem *)malloc(5);
    mainMenu[0].subMenu[0].iconHigh = loadImage("./img/mainmenu/s_eq_high.png");

    while(1)
    {
        if (mainMenu[0].subMenu[0].iconHigh) {
            blitAlphaImageToScreen(0 ,0 ,32 , 32, mainMenu[0].subMenu[0].iconHigh, 0, 0);
        }
    }

---

The problem is that the picture's all messed up:

You probably put the wrong width and height values. You should do

Code:

---

blitAlphaImageToScreen(0 ,0 mainMenu[0].subMenu[0].iconHigh->imageWidth, mainMenu[0].subMenu[0].iconHigh->imageHeight, mainMenu[0].subMenu[0].iconHigh, 0, 0);

---

No, the width and height are definitely correct. Including the image directly (using a var Image *tmp for loadImage()) it works just fine

I am trying to hook some firmware functions (in a devhook prx) so that I can draw my menu on the screen whenever the sceDisplayWaitVblankStart function is called so that everything is ALWAYS drawn on top of the current frame and I won't get flickering. I am also trying to hook the audio output functions (sample code below) to add a boost function like in PMP Mod AVC, except this would boost all output. I have tested the code for finding the offsets for the NIDS that I need to patch, and it does find the correct ones, but there is something wrong with either my patched functions or the actual patching of the functions. As soon as a sound is played the PSP freezes, indicating that the right NIDS are patched but that something causes it to freeze. In my original code I would patch the sound functions whenever I chose to in my menu, and in that way I found out that it patches the functions but whenever I would press a button on the D-pad to trigger the sound it would freeze. Can someone help me figure out what is wrong with my code? Below is a stripped down version of my code that simply patches the functions when it loads.

That problem is, thanks to СУ&am solved now :)

So I got time to come back to the transparency Issue.

Well, I use this to set the alpha value of images:

Code:

---

void SetAlphaImage(Image * image, unsigned int alpha)
{
        int size;
        Color *databuf;

        if(!image->data)
                return;
               
        if(alpha>255) alpha = 255;
        if(alpha<0) alpha = 0;

        size = image->textureWidth * image->textureHeight;
        databuf = image->data;

        for(i = 0; i <= size; i++)
        {
                *databuf = (*databuf & 0x00ffffff) | ((A(*databuf)-(A(*databuf)-alpha))<<24);
                databuf++;
        }
}

---

---

It neither has a return value, nor does it affect the Image-pointer, so how do you use it? (sorry, I still am a noob)

Looks like it affects it to me mate.

Follow the function through logically - it's pretty easy to understand.

What are you trying to achieve exactly? I feel there will be an easier and faster way to execute it. The above function will be quite slow.

well, i tried this:

Code:

---

void Controls() {
//read pad//
        if (pad.Buttons & PSP_CTRL_SELECT) {
                saveImage("test1.png", getVramDisplayBuffer(), 480, 272, 480, 1);
        }
}

---

but when i try to compile it, it gives an error:

Code:

---

undefined reference to 'getVramDisplayBuffer()'
undefined reference to saveImage(const char*, unsigned int*, int, int, int, int);

---

how can i solve that?

---

I can't believe I missed this the first time around. If you look at my function you will see that you only have to supply the filename and none of the other arguments.

Just do:

Code:

---

IMG_Screenshot("myImage.png");

Yeah ok. I already wanted to edit my post. I used it but it turns my partially transparent PNGs into transparent squares :S. What I want to do is fade out the images of my mainmenu... .

Faster way, draw a quad over the top that's black (or whatever color you want to fade out to) and covers the entire screen and then alter the alpha value of the color.

Something like this:

Code:

---

//////////////////////////////////////////////////////////////////////
// Name: FadeScreen
// Purpose: Fades the screen in/out (white)
// Returns: NONE
// Usage: Pass a value from 0.0f increasing to 1.0f to fade in,
//        1.0f decreasing to 0.0f to fade out
//////////////////////////////////////////////////////////////////////
void FadeScreen(const float FadeInAlphaValue)
{
guStart();
sceGuDisable(GU_TEXTURE_2D);
CSVertex* vertices = (CSVertex*) sceGuGetMemory(2 * sizeof(CSVertex));
          vertices[0].color = GU_COLOR(1.0f, 1.0f, 1.0f, FadeInAlphaValue);
          vertices[0].x = 0;
          vertices[0].y = 0;
          vertices[0].z = 0;
          vertices[1].color = GU_COLOR(1.0f, 1.0f, 1.0f, FadeInAlphaValue);
          vertices[1].x = 480;
          vertices[1].y = 272;
          vertices[1].z = 0;
sceGuDrawArray(GU_SPRITES, GU_COLOR_8888 | GU_VERTEX_16BIT | GU_TRANSFORM_2D, 2, 0, vertices);
sceGuEnable(GU_TEXTURE_2D);
sceGuFinish();
sceGuSync(0, 0);
}

---

Where CSVertex is:

Code:

---

typedef struct
{
        unsigned int color;
        short x, y, z;
} CSVertex;

---

You can of course alter the function to take your own arguments - but this one is hard set to white.

Sometimes you have to change the alpha value without making a fade effect though...

I believe this should save the transparency that's already there:

Code:

---

void SetAlphaImage(Image * image, unsigned int alpha)
{
        int size;
        Color *databuf;

        if(!image->data)
                return;
               
        if(alpha>255) alpha = 255;
        if(alpha<0) alpha = 0;

        size = image->textureWidth * image->textureHeight;
        databuf = image->data;

        for(i = 0; i <= size; i++)
        {
                *databuf = (*databuf & 0x00ffffff) | ((A(*databuf)-(A(*databuf)-alpha))<<24);
                databuf++;
        }
}

When I call drawSubMenu with 0 as a parameter everything works fine. Using 1, which means using the 2nd part of the Array, the PSP freezes

en here is the makefile

Code:

---

TARGET = calculator
OBJS = main.o danzeff.o

CFLAGS = -O2 -G0 -Wall
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)

EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = calculator

PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak

[/code]

There's a readme that comes with danzeff OSK.

Read it.

You need to choose within danzeff whether to use GU or SDL.

that's the point i dont understand the readme:(

i want the use the SDL_Joystick

but dont know how do change it

You need SDL installed to be able to use it...

I think the default for danzeff is SDL.

Uhm, I compared this with the old version and I don't actually see a difference.

My recent Problem: (sorry for so many code)
[ code ]
When I call drawSubMenu with 0 as a parameter everything works fine. Using 1, which means using the 2nd part of the Array, the PSP freezes

Problem solved

Glad to hear it.

hay i was wondering if any one can help give me a code to check if a file exists then load it and have it tell me when it exits i look all over but i couldnt find any.

could just do:

file = fopen("./file.txt", "r");
if(file==NULL) { //file dosn't exist
} else {
//file exists
}

To check if a file exists you simply do

Code:

---

//Open the file, change file path to the file you wish to check. rb indicates that it opens in read-binary mode.
FILE * file = fopen("file path", "rb");
//If file==0 (same as !file) the file doesn't exist
if(!file) { printf("file does not exist"); return 0; }
//Close the open file
fclose(file);
return 1;

Not sure what you mean by the "exit" part though.

what i ment was when the app i loaded exits out of itself that i want it to tell my program that it exited and do something

Oh, in that case. Just add this to your main (preferbly where you intialize the app)

Code:

---

int cbid;
cbid = sceKernelCreateCallback("Exit Callback", exit_callback, NULL);
sceKernelRegisterExitCallback(cbid);

---

And then add this

Code:

---

/* Exit callback */
int exit_callback() {

  //Add stuff here       

  sceKernelExitGame();
  return 0;
}

actualy I mean when i load the app that i checked if it exists when that app exits then i want it to do something.

whats the screen brightness button code

whats the screen brightness button code
(the one beside note)

PSP_CTRL_SCREEN = 0x400000
It can only be read in kernel mode.

Can it be modified?
