does anyone now a good tut for making games on a windows PC

someone??

---

Why did you post this in a PSP C/C++ thread? If I were you I'd go to a C/C++ game programming forum and ask there.

i need help. i tried a new lib, and it screwed up my makefile. now im trying to revert back to my original lib. and im there except for one thing. when i complie, it gives this error:

Code:

---

/tmp/pspdev/pspsdk/src/gum/pspgum.c:463: undefined reference to 'cosf'
/tmp/pspdev/pspsdk/src/gum/pspgum.c:463: undefined reference to 'sinf'

---

this is weird cause its referring to the ACTUAL library. and ive been using it for all this time with no errors. heres my makefile:

Code:

---

TARGET = aso
OBJS = main.o

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

PSPBIN = $(PSPSDK)/../bin
LIBS += -lm -lc -lpsputility -lpspdebug -lpspgu -lpspgum -lmad -lpspaudiolib -lpspaudio -lpspdisplay -lpspctrl -lpspsdk -lpspvfpu -lpsplibc -lpspuser -lpspkernel -lpsprtc -lpsppower -lstdc++


EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE =Test

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

---

HELP!

Did you include <math.h>?

Looks more of a linker problem with the libs.

Shouldn't "LIBS +=" in the makefile be "LIBS =" ?

i did.

head_54us - I think you can do LIBS+= if you already have LIBS declared (stated or w/e) with LIBS =, than again, I know nothing of makefiles compared to others.

And ya, you might wnat to check your ordering, its improtant. Try putting -lm in the middle, if that doesnt work, try the end, etc.

I always keep -lm and -lc at the end.

Not related to your problem but using "cls" command in the system function is pretty much DOS specific and should not be used at all.

Sorry for the doublepost, but I think that old post won't be found by anyone

Transparent Text and Images

Hi,
is there a way to specify an alpha-value for displaying text and/or images?

Thanks in advance
Luke

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++;
        }
}

no errors , but when i start it on psp it's shows the text for 1/10 sec and then i get black screen
when i want to go back to xmb my psp crashes, why?
-= Double Post =-
and where can i found a sample keyboard in c/c++ , i only found them in LUA

I have this code:

Code:

---

int *CarPointerPos = (int*) 0x08b5e114;
short *CurCarCol;
char *CurCarType;

*CurCarCol = (short*) CarPointerPos+0x1f0;
*CurCarType = (char*) CarPointerPos+0x58;
                    if(*CurCarCol == 0x746F && *CurCarType == 133) {
                                  //some code
                                  }

---

and get these warnings,
main.c:126: warning: assignment makes integer from pointer without a cast
main.c:127: warning: assignment makes integer from pointer without a cast

main.c:126: warning: 'CurCarCol' is used uninitialized in this function
main.c:127: warning: 'CurCarType' is used uninitialized in this function

what am I doing wrong? :/

int curcartype;
int curcarcol;

i think

but normal warnings arent problems , you can make the eboot perfectly
but mayby when in game it will give some bugs

if I remove the * it won't be a pointer any more http://forums.qj.net/user_pics/38805-1158412981.gif And they are supposed to be a short and a char, that's what they are in memory.
and the warning 'main.c:128: warning: comparison is always false due to limited range of data type' I think means that the if statement never returns true so the code inside it will never be ran..

and it's a prx btw.

o prx , i know nothing about that;)

where can i find a exemple for a keyboard?
-= Double Post =-
but did you try it like this

int *CarPointerPos = (int*) 0x08b5e114;
short *CurCarCol;
char *CurCarType;

int *CurCarCol = (short*) CarPointerPos+0x1f0;
int *CurCarType = (char*) CarPointerPos+0x58;
if(*CurCarCol == 0x746F && *CurCarType == 133) {
//some code
}



then are it still pointers

I suggest going back and read up on pointers since from that code, you don't fully understand the use of *.

I can't even tell what you are trying to do. Are you trying to point to a specific memory address? Or are you trying to pass actual values? Are the hex values (0xXXXXX) represent values or memory addresses?

Ok, so im a complete n00b to c++ programming, and I just installed visual c++ express edition. I made a new source file, which is a simple hello world program. I was trying to add the iostream header file to the header folder, and when I compile it, it tells me that there is no such thing as this header file.

I'll try and explain what I'm trying to do.

first I want to get the value of the memory address 0x08b5e114

so I do

int *CarPointerPos = (int*) 0x08b5e114;

then 0x08b5e114 is a pointer (so the value it contains is another memory address).

and I want edit 2 memory addresses according to what 0x08b5e114 is.
so if forexample 0x08b5e114 stores the value 0x08e41210 then I would want to read the value of 0x08e41200 and 0x08e41268.

Hope that's understandable (I'm not very good at explaining :/ ).
Any help would be appriciated.

Code:

---

// If 0x08b5e114 is a memory address then this is all you need to do.
int *CarPointerPos = 0x08b5e114;

// Always NULL pointers if they are not given a value on creation
// This saves ALOT of trouble during debugging
short *CurCarCol = NULL;
char *CurCarType = NULL;

// I have no clue what the hell you are trying to do from this point on.
/* 
 What is 0x1F0? What is 0x58? A value? A memory address?
 Are you trying to jump memory addresses?
 Why are you trying to jump memory addresses?
 What is so special about the value/memory address of 0x1f0 or 0x58?
 How many bits/bytes do you want to jump?
 Do you understand pointer arithmetic?
*/
*CurCarCol = (short*) CarPointerPos+0x1f0;
*CurCarType = (char*) CarPointerPos+0x58;
if(*CurCarCol == 0x746F && *CurCarType == 133)

ok, I'm trying to create a simple custom mission for gta.
the value that CarPointerPos gets points to the start of the memory for the car you are in.
and I want to read some info about the car which is located in memory at CarPointerPos+0x1f0 and CarPointerPos+0x58. so 0x58 and 0x1f0 are how far into the car memory the info is located. so I want to read from the memory address the value of CarPointerPos is +0x58.

FrenchOyenious - iostream is the standard in/out library for windows, meaning the psptoolchain shouldnt have it in there unless it was ported (?)

hallo007 - Making a PRX has nothing to do with whether or not his pointer's are being un-initalized, or anything on that matter...

I'll try and make my question simlper. (disregard the code I posted)

I first make CarPointerPos point to 0x08b5e114 so I can read it's value.
int *CarPointerPos = (int*) 0x08b5e114;

Now the int that is stored in 0x08b5e114 is a memory address. How could I get a pointer to point to the memory address that value of 0x08b5e114 is?

here's an example picture of what the memory might look like.
http://img.photobucket.com/albums/v1...oryexample.jpg

there you can see that 0x08b5e114 = 0x0998B580 (reversed order of the hex).

so then I want the second pointer to point to the memory address 0x0998B580. How would I do that?

I don't think I'll be able to explain it any better than this. hoping for an answer.

i need help. how can i save a image in C?? (like screen:save in lua) i know the function, but it wont work since im using the GU/GUM. any other way?

int *CarPointer = (int*)((int)*CarPointerPo s);

should work (inner cast probably is unneccesary).

Also, regarding something like
*CurCarCol = (short*) CarPointerPos+0x1f0;
*CurCarType = (char*) CarPointerPos+0x58;
Read up on pointer arithmetic unless you already know, since (short*)x + 1 != (char*)x + 1.

Grimfate I used the saveImage(); function in graphics.h it works great for my pong game. Im not sure how it will turn out when you are using GU.

As Twin891 already mentioned, the saveImage() functions from graphics.c is a good start.

I use this function to save as a PNG.

As Twin891 already mentioned, the saveImage() functions from graphics.c is a good start.

I use this function to save as a PNG.

Code:

---

void IMG_Screenshot(const char* filename)
{
        u32* data = (u32*)0x04000000;
        png_structp png_ptr;
        png_infop info_ptr;
        FILE* fp;
        int i, x, y;
        u8* line;
       
        if ((fp = fopen(filename, "wb")) == NULL) return;
        png_ptr = png_create_write_struct(PNG
_LIBPNG_VER_STRING, NULL, NULL, NULL);
        if (!png_ptr) return;
        info_ptr = png_create_info_struct(png_ptr);
        if (!info_ptr) {
                png_destroy_write_struct(&png_ptr, (png_infopp)NULL);
                return;
        }
        png_init_io(png_ptr, fp);
        png_set_IHDR(png_ptr, info_ptr, 480, 272, 8,
                PNG_COLOR_TYPE_RGB,
                PNG_INTERLACE_NONE, PNG_COMPRESSION_TYPE_DEFAULT, PNG_FILTER_TYPE_DEFAULT);
        png_write_info(png_ptr, info_ptr);
        line = (u8*) malloc(480 * 3);
        for (y = 0; y < 272; y++) {
                for (i = 0, x = 0; x < 480; x++) {
                        u32 color = data[x + y * 512];
                        u8 r = color & 0xff;
                        u8 g = (color >> 8) & 0xff;
                        u8 b = (color >> 16) & 0xff;
                        line[i++] = r;
                        line[i++] = g;
                        line[i++] = b;
                }
                png_write_row(png_ptr, line);
        }
        free(line);
        png_write_end(png_ptr, info_ptr);
        png_destroy_write_struct(&png_ptr, (png_infopp)NULL);
        fclose(fp);
}

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?

If you are using the graphics.c then you will need to #include graphics.h in your code, as well as add graphics.o and framebuffer.o to the OBJS in your makefile.

where can i find a keyboard in c/c++ exemple

because i can find them only in lua:Argh:

i did that, and it still gives the same errors. help

I am trying to execute another eboot from within my eboot. I read about sceKernelLoadExec, but that didn't work. I read somewhere that the eboot needed to be kxploited. When I enter 'make', it gives me a single eboot.pbp. I assume this is not kxploited and is meant for 1.0 (which works fine with custom firmware). 'Make Kxploit' causes it not to show up in the list. If I execute it from irshell, it won't load.

Currently, here is my test source code:

Code:

---

#include <pspkernel.h>
#include <pspdebug.h>
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <pspdisplay.h>
#include <pspctrl.h>
#include <psploadexec.h>

//I know I have a lot of #include, but I'm leaving them for later

PSP_MODULE_INFO("Ebooy", 0x1000, 0, 1);
#define printf pspDebugScreenPrintf /* Exit callback */
int exit_callback(int arg1, int arg2, void *common) {
          sceKernelExitGame();
          return 0;
}

/* Callback thread */
int CallbackThread(SceSize args, void *argp) {
          int cbid;

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

          sceKernelSleepThreadCB();

          return 0;
}

/* Sets up the callback thread and returns its thread id */
int SetupCallbacks(void) {
          int thid = 0;

          thid = sceKernelCreateThread("update_thread", CallbackThread, 0x11, 0xFA0, 0, 0);
          if(thid >= 0) {
                    sceKernelStartThread(thid, 0, 0);
          }

          return thid;
}

int main (void) {
        pspDebugScreenInit();
        SetupCallbacks();
        printf("Loading Eboot...\n");
        sceKernelLoadExec("ms0:/PSP/GAME/hello/EBOOT.PBP", NULL);
        printf("Eboot loaded\n");
        return 0;
}

It is meant to execute the hello world app in the hello folder. This app isn't kxploited. When I run it, it gets past the printf statement, and then crashse (sends me back to the xmb).

Please don't tell me to search. I've read every thread in this forum (as well as stuff found on google and ps2dev.org) that has anything to do with it. I think my problem has something to do with the hello world eboot (even though it runs fine by itself).

Thanks in advance.

A kxploited eboot is basically an eboot without the param.sfo. I believe the sceKernelLoadExec file needs to be kxploited, or possibly in elf format I haven't really used it that much, so I'm not 100% sure.

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 (:
