C/C++ Programming Help Thread

super - You specifically said you had made a game in C for the PSP sometime ago. You never stated C for the PC, and even still, PC programming would have taught you how loops work and basic number arithemtic. Ive been a snob latley, because ever since I talked to you that first time on MSN, you talked pretty high of yourself ("im going to optimize TP's code even more" as an example, where his code was as optimized as it could get, unless you wanted to spend all afternoon unwrapping for loops). I was ok with it, as I hadnt seen any of your code or your programming style, but soon after, you asked me many questions regarding simple things. such as "how do i store an image in a buffer?". Than, after answering quite alot of questions regarding g-pack's shell (such as "how do i make a mouse/cursor?"), you refered to me as a god, and when TP joined, he as well. Than when I had said Im ditching Lua for C now that I have my PSP back,you were saying something like how you hate lua and want to go back to C, which makes me think you think C is better than Lua and why all of a sudden would you chose to go back to C when Lua hasnt limited YOU yet, when really, its the programmer, not the language (although a good portion of it is the language). All of this has been bottling up inside me, and now its all slowly pouring out. Im not trying, nor am, a know it all, but alot of things coming from you contradicts what you've said to me on MSN and other means of communication. Im going to stop doing it now, as they are starting to come off as flames, but i dont feel any different...

On Topic:

Ok, Im just quickly getting back into my PSPGL phase, and to start, Ive made a PSP version of the stanford rabbit. Ive made the model into a display list, to help my framerate along, and am happy to say it runs 60 FPS, and sure enough, displays the rabbit. I have the rabbits normals applied to the vertex array, and when using them to light the rabbit, I result in a rabbit whose colors are all one shade, Rather than having a nice metalic look, I get this:
http://jordansg57.googlepages.com/snap0002.JPG
meaning, one normal is affecting all of them (im guessing). Does anyone know what might be the problem? If you need to see some code (and no my normsl ARENT the same within the vertex array) than post so. Oh and yes, i can rotate the rabbit, and can definatly say one normal is affecting the entire model :( Oh and yes i have lighting enabled ;)

Zitat:

Oh and yes i have lighting enabled

---

But most likely wrongly. Only other chance would be that your vertex normals are really the same all over your mesh or you just didn't set smooth shading. Some insight into your code might help.

Well, I now have a nice 3D world going, I move via /\, [], O and X, look around via Analog stick. Raphael - would you mind running my currnet build and seeing what it looks like? It has lighting, as iit lightens/darkens from different angles as it should, but not as it looks in screenshots of other versions. Also, you could tell me what you think of the control scheme, too fast, too slow, as Im always picky about my speed, so a second opinion would help alot (and your one of few, if any, 3d-intelligent people that is online right now.)

You can't compare strings with the == operator (at least not in C). Use strcmp.

---

THNX:tup:

if (strcmp (szKey,szInput) != 0)

Code:

---

  char *checkextension;
 
  int size=0;
  SceUID in;
  in = sceIoOpen(wat, PSP_O_RDONLY, 0777);//open de geselecteerde file
  filesize = sceIoLseek(in, 0, SEEK_END);  //bereken de grootte van de eboot 
  printf("Opening EBOOT....size: %d kb\n" ,filesize/1024);
 
  sceIoLseek(in, tmp->psar, SEEK_SET); //zoeken naar data.spar in eboot
  sceIoRead(in, checkextension , 4);
 
  if( strcmp (checkextension,"PSAR") != 0)//als er een dat.spar is
  {

---

that needs to be true :) first go to school now , i can test it in 8houres:)

Just a tip- strcmp actually returns 0 when the two strings are the same. So it would be:

Code:

---

if( strcmp (checkextension,"PSAR") == 0)

---

unless of course you meant it to do something when they aren't the same.

Is their a PSP emulator where i can test my EBOOTs instead of keep on transferring them to my PSP? I know PSPE is one but i think it uses an older version of the SDK/Toolchain.

Just to finish off strcmp's return values ;), it returns however many characters one string is, longer than the other. If they're the same length, then itll return 0, as strlen(str1)-strlen(str2) = 0 when they're both the same..

Raphael - Ive ditched the bunny, it was just to refersh my memory on how display lists work. Now, Ive got the mechanics of a good 3D maze game, well... good anything really, it could be applied to a FPS, but im not that far yet and dont want to be overwhlemed :o (i can walk around, strafe, and look around via analog stick). Now, Ive created a neat little sky box function, which asks for where you want it. and autmatically centers it so I could, in theory, have the sky box 'follow' my camera. Itd look pretty bad, but itd be pretty neat to try out. Anyways, my sky box works, and works dandy i might add, but it has some nasty culling :( Im thinking of a way to project the sky box images, onto smalelr quads, so only the small quads are culled when 3 of their verticies arent on-screen, and if i make each one less than 1 pixel in size, it shouldnt even be visible, the culing.,.. What do you say to this idea? Any better ideas? If not, know a way to do as ive said? I have ONE theory i could try, but if it doesnt work im stuck :( So hopefully you can help before hand.

Wow, nice gfx. I looked at the first post and saw that you posted this thread. You must be very famous for it. Anyways, let me introduce myself guys, i am Xylem (i would not like to give out my real name). I signed up at QJ around 15 minutes ago, but i have coming here often to the front page and downloading things from the download section. However, i just learned today that there are forums here, so i obviously signed up! Another thing, i am a newbie in C programming, and i would like to program in lua or C for the psp. If i have any questions, i will come here to post them (hopefully you guys don't mind answering questions). Also, i searched for quite a while and learned at lua programming is easier than C, but C has more capability. I would rather like to learn C first though, and i think you guys will like having me here (hopefully!).

Use smaller triangles and more of them. Also increasing your near plane value will help the triangles to not get clipped.

Anti-QJ, use psplink. It's not an emulator but you can use it to load your programs on your psp from your pc's terminal window via USB or wifi no copying over to the psp necessary.

Code:

svn co svn://svn.ps2dev.org/psp/trunk/psplink

Thanks dude! :tup:

Insomniac - That was what I was planning on doing as my theory. I need to project my texture over enough triangles, to the point where each one is smalelr than a pixel on screen, that way when they do get culled, it won't show as the one next to it is in it's place and showing hte texture as it should. I just need a method of projecting the texture over a lot of triangles. I remember i asked this as ps2dev a way while back, so ill check there in the morning, Til then, im off to bed as i have school tomorrow, and homework i need to do during school :p

Also, after placing a simple cube that would resemble a person in my little world, the sky box is HUGE... With nothing else but it there, it doesnt seem to big, rather that your walking slow. But after placing a cube in there, i saw just how big it is... I say I could fit a nice little maze within it. Once that is done, ill start with heightmapping and collision on all 3 axis (right now i just substitute the Y axis as the Z, with a few tweaks so it turns out right...)

I wouldn't make your triangles that small.

Just tesselate your mesh until you get a decent result.

Good luck with the 3D collision.

By the way, sky dome > sky box ;)

sill not working:(

Code:

---

  sceIoLseek(in, tmp->psar, SEEK_SET);
  sceIoRead(in, checkextension , 4);

  if( strcmp (checkextension,"PSAR") == 0)
  {

---

if( strcmp (checkextension,"PSAR") == 0) is still false :(

mayby the fault is here sceIoRead(in, checkextension , 4);
what it needs to do , reading the offset and stores the first 4 bytes in checkextension , that 4bytes need to be PSAR

hallo - extensions usually start with '.'. Maybe it's returning false because your comparing '.PSA' with 'PSAR'.

Insomniac - Sky dome is better, but I dont want to mess with spheres until I know I will get a decent framerate (i havent hte slightest clue whether or not a cube takes less CPU than a sphere when creating/rendering, but seeing as how a sphere must have ALOT of verticies, Im guessing the cube is less of a hassle with the CPU.. :( Please correct me if im guessing wrong).

Oh and I think you mean 'tessellate' ;) And I know i can make alot of small squares make up a wall, but hte problem is that I need to than project my texture over them. To do this, Im thinking of using offsets of the texture per square. Im looking into it now as we speak. Once thats done, ill apply collision, than make a start and finish with their appropriate collision and whatnot. Than, ill start my map structure...

Ok, i know how to do it. When setting the UV coordinates, its as if im setting offests. Now itll be very easy to do.
-= Double Post =-
Is anyone on right now, that has some knowledge of using a 3D API? I have a few questions, one thing new I learned is setting a textures envirorment parameter to GL_DECAL, rather than GL_MODULATE, it will prevent any lighting and/or coloring done to the texture, this was currently a problem as whenever I drew ANYTHING, be it a cube or my gridded ground, id get a colored sky box, now it's just peachy.

But, im still having trouble with culling. Setting my near-z value in my perspective to a greater amount, certainly has helped (now the grided floor shows, but not both ses of lines all the time. I have a question though, setting it any higher (right now it's 2.0f, the default (my regular usage) is 0.1f) make it worse? Also, if someone is on (Raphael, Insomniac, yaustar, etc.) is there anyway i can talk to you via instant messenger? Be it, IRC, MSN, Aim or some other type of messenger? Thatd be great :o Im still a novice at 3D programming, but Im moving, slowly but surely.

You can increase it past that, but it's never going to be a complete way of avoiding the clipping.

Subdivision (whether it be lines, triangles or whatever) combined with increasing the near plane is a decent way of doing it.

I've PM'd you my AIM, I'll be home from work in less than an hour.

@hallo007: That's because you do something very bad and that is writing to unallocated memory:

Code:

---

  char *checkextension;
  ...
  sceIoLseek(in, tmp->psar, SEEK_SET); //zoeken naar data.spar in eboot
  sceIoRead(in, checkextension , 4);
 
  if( strcmp (checkextension,"PSAR") != 0)//als er een dat.spar is
  {

---

Make that first line THIS instead:

Code:

---

char checkextension[5];
checkextension[4]=0;

---

@SG57: You NEED to tesselate/subdivide your faces on PSP to avoid unwanted culling. There was a very good thread on PS2dev where someone explained the exact reason for the PSP to act like that. Also, you can reach me via ICQ most of the time (just not this week, because I'm not at home).
Also, regarding your texture modes, try GL_REPLACE if you want to completely avoid any mixing of the texture with the background. GL_DECAL is another apply mode that still blends in the current fragment (vertex) color when the color mode is GL_RGBA. GL_DECAL == GL_REPLACE for GL_RGB though.
Read here for a complete specification of the modes (it's for openGL-ES actually, but it's the same for standard openGL).

ok i have just gone back to realy basic code to re freash my memery and i can work out why this simple code doesn't work.

Code:

PSP_MODULE_INFO("CONVERTER", 0, 1, 1);
#define printf pspDebugScreenPrintf

int exit_callback(int arg1, int arg2, void *common) {
          sceKernelExitGame();
          return 0;
}

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 dec1 = 234;
int bin1 = 0;

#define RGB(r, g, b) ((r)|((g)<<8)|((b)<<16));

int main() {
pspDebugScreenInit();
SetupCallbacks();

if (dec1 > 255) {
pspDebugScreenPrintf("ERROR ");
}

if (dec1 < 0) {
pspDebugScreenPrintf("ERROR ");
}

if (dec1 >= 128) {
bin1 = 10000000;
dec1 = (dec1 - 128);
}

if (dec1 >= 64) {
bin1 = 1000000;
dec1 = (dec1 - 64);
}

if (dec1 >= 32) {
bin1 = 100000;
dec1 = (dec1 - 32);
}

if (dec1 >= 16) {
bin1 = 10000;
dec1 = (dec1 - 16);
}

if (dec1 >= 8) {
bin1 = 1000;
dec1 = (dec1 - 8);
}


if (dec1 >= 4) {
bin1 = 100;
dec1 = (dec1 - 4);
}

if (dec1 >= 2) {
bin1 = 10;
dec1 = (dec1 - 2);
}

if (dec1 >= 1) {
bin1 = 1;
dec1 = (dec1 - 1);
}




printf(bin1);
printf(dec1);


sceKernelSleepThread();

return 0;
}

---

mafia1ft: It's because printf requires a char variable, and you're giving it an int. Try printf("%i", bin1); instead of printf(bin1);.

PS: If you're supposing to print the binary representation of a number with that, then you're off. It will only print the least significant one-bit. If you want the real binary, use bin1+=.
Also, there are more elegant ways to get done what you want :P Try using a loop and use shifts.

I can't find that file in my include dir, can you upload pspsyscon.h?

It'd be no use on it's own.

This is why you should install the toolchain yourself and not use one of those pre-packaged binary setups, you're stuck with whatever revision the setup has.

If you have installed the toolchain yourself, then update it.

Well, that 'crap' is your poor programming skills in action (or copy paste job ;)). My best guess is that your trying to compile that plasma demo someone made over at psp-programming, or some variation of it, and not linking the correct libraries needed on the LIBS line.

Im thinking of getting rid of the scaling, along with translation call in the function, and using the verticies points for where to place them, and to 'scale' them (i wont actually scale htem, rather just build the sky box the size it is, without scaling a 1x1x1 cube).

I'm having a problem running the toolchain.sh file when setting up the toolchain. Here's a screenshot of it:

Atin, some guy just posted this thread:
http://forums.qj.net/f-psp-developme...ead-95565.html

Try posting it there, he may be able to help. I personally don't know much about this, since i myself haven't completely installed cygwin yet.

That guy is super, and he totally disregarded a largely spread rule, *Search*.

AS for your problem Atin, I had the same problme a long time ago, I made a tutorial on how to do it with that error, it ended up with me downloading whatever link to the file it was trying to get. There's 3 in total; binutils,newlib and gcc i believe...

Thanks that's exactly what I needed.

All with the same or nearly hte same problem as Atin, check my newly created thread here, or go here:
