check the sdk samples in the gu folder, there maybe something there ?

[Gh0sT]

Hey everyone or anyone,

I'm trying to include pspmath.h into one of my projects, but I have no idea how to accomplish this.

Tried search these forums and Google without luck so I decided to ask here.

Hope someone can help me out.

Thanks in advance,
Gh0sT

[MrChaos]

Can't find an example there. What I'm trying to do is move away from LUA. So I'm making a game in C, got the menu to show up, but nothing is rendering so I can't use it.


Gh0st,

#include <pspmath.h> ?

[eldiablov]

ghost try <math.h>

[Gh0sT]

#include <pspmath.h> ?

Thanks, but obviously I tried that. Think I don't have the appropriate lib installed.

main.c:8:21: error: pspmath.h: No such file or directory

EDIT:

ghost try <math.h>

OMG, that actually worked! Thanks alot!

Greets,
Gh0sT

[MrChaos]

Oh, and I got another question. Can you include images in a EBOOT, instead of having to put them in a folder?

(Meaning PSP/GAME/[Gamefolder])

[eldiablov]

np Ghost :)

Anyway mr chaos when you compile an eboot images are compiled aswell so you wont see them in a folder.

Do you have the toolchain and cygwin installed MrChaos ?

[MaTiAz]

Anyway mr chaos when you compile an eboot images are compiled aswell so you wont see them in a folder.

He didn't mean that....

MrChaos: Yeah, use bin2c <filename>, that creates an unsigned char of the file, then you include <filename>.c in your makefile as <filename>.o. After that, you just load the image from a buffer instead of a file.

[michaelp]

is there anyway to test your eboots made in C on your computer?

[yaustar]

is there anyway to test your eboots made in C on your computer?

Short answer, no. Long answer, yes but you have to design your code so it can be compiled on different platforms.

[hallo007]

so specific app's no , games are a bit possible

[MrChaos]

I still need help rendering something in a program.

Ex. Making a menu render, so I could swap bettwen menu options. What am I missing, cases?

[michaelp]

hey when you make an EBOOT.PBP, can you edit what you put in later, or would you have to make a whole new EBOOT?

[slicer4ever]

new eboot

[michaelp]

damn
well, i think i'm gonna quit lua and start learning C, because it'll help in the long run

[SG57]

Does anyone know whether or not the psp-gcc will support Obj-C at some point? Itd be a great new learning experience for me to learn Obj-C, but I dont want to as my main console i develpe for is the PSP :-\

Thanks.

[slicer4ever]

ok i need some help as i'm very close to release my beta of celestial cunning but i've come up 2 a prob which i can't seem to find a solution 2(probably well after i post)

now then i believe the following code goes somehow into an infinite loop because normally when my program stops it quits after a moment but this just freezes all movement and the home button quits working so that is why i conclude it enters an infinite loop anyways any1 who can help me would be much appreciated

Spoiler for code:

void attacking(int unit_number_f){
     int attack_unit=-1;
     unit_attack_scan_time[unit_number_f]++;
     if(unit_attack[unit_number_f] != -1){
          sprintf(printing_text,"attacking: %d",unit_attack[unit_number_f]);
          printing(0,0,printing_text);
     }
     if(unit_attack_scan_time[unit_number_f]>fps*30 && unit_attack[unit_number_f] == -1){
          if(unitstatus[unit_number_f]==-1 && unit_attack_able[unit_number_f]==0){
               for(i=0;i<10;i++){
                    for(d=0;d<10;d++){
                         for(g=0;g<unit_num;g++){
                              if(attack_unit == -1){
                                   if(round(unitx[g+1]) == round(unitx[unit_number_f])+i || round(unitx[g+1]) == round(unitx[unit_number_f])-i){
                                        if(round(unitz[g+1]) == round(unitz[unit_number_f])+d || round(unitz[g+1]) == round(unitz[unit_number_f])-d){
                                             if(unit_owner[g+1] != unit_owner[unit_number_f]){
                                                  attack_unit=g+1;
                                             }
                                        }
                                   }
                              }
                         }
                    }
               }
               if(attack_unit != -1){
                    unitstatus[unit_number_f]=4;
                    unit_attack[unit_number_f]=attack_unit;
                    unitgx[unit_number_f]=round(unitx[unit_attack[unit_number_f]]);
                    unitgz[unit_number_f]=round(unitz[unit_attack[unit_number_f]]);
               }
          }
          unit_attack_scan_time[unit_number_f]=0;
     }

thats not the full function but the part that i've concluded enters the infinite loop or slows down the program an extreme amount(unlikly more likly of infinite loop 2 me)

anyways don't tip me on optimising just help me fix it and thanks

(also good 2 be back)

[SG57]

I dont see a problem there, however i have only looked at the conditions for the statements.

However, one thingi might add is that when you setup your callbacks, your setting up an entirely new thread that the home button is hooked to and starts it. Having teh home button stop from working means a crash stopping the polling for Home button pressed. If that is wrong, please correct me, as thats how ive seen it.

[slicer4ever]

i don't see a prob either yet after many tests i know thats the source, although i'm not 100% sure if it is a crash as like i said after a moment it usually shuts down when crashed from what your saying it sounds like it crashes yet i can't find the source to this crash (which has to be there somewhere) which rly sucks cause if i can get this 2 work then i can release a beta of celestial cunning
-= Double Post =-
ok i fixed it which is good but now i have a few new bugs so hopefully my beta well be out by tommorow or maybe later tonight

[vodkkaa]

I want to create a app that will change the firmware system version. What im thinking of doing is having a TXT file with the system version yuo want written into it then the app will covert it to unicode and overwrite the offsets in the vshctrl.prx in flash0:/kn. how would i go about doing this

BTW: Yes i know there are apps that can change system version but i am a trying to improve my coding and want to create one myself

[michaelp]

Okay, I want to start learning C, so I need CYGWIN right?
I transfered the PSPtool chain and CYGWIN to a computer in my room that DOES NOT HAVE internet.
So I tried the option "install from local directory"
But when it ask where to save the install files or whatever it is, a message comes up say that I have performed an illegal operation.

It's a Windows '98 computer.

Also, could I install CYGWIN on a computer, than transfer the files that were installed to the '98 computer?

[seenit]

you need the internet unfortuantly for toolchain and to use the setup of cygwin

[eldiablov]

michael i have told you countless times to use THE PRECOMPILED ENVIRONMENT !!!

[Kwastie]

I creating a whooping Stopwatch XD:ROFL: just to improve my coding skill's but
but the screen is flickering as hell, so does someone know at what rate i don't see it flickering any more?!?
or is there a way i only have to refresh the numbers of my stopwatch , the whole menu get's

sceKernelDelayThread(1000 000); = 1 seconde
my pc has about 80 Hz so if I refresh the screen but for calculating 100 Hz is much better
@ 1000000/100= 10000 so if I do
sceKernelDelayThread(1000 0) it has 100 Hz?!?

i'll give a example

printf(" Your running this program for");
printf" i%", hour)
printf":i%", minute)
printf":i%", seconde);
sceKernelDelayThread(10000)
ms ++
if (ms > 100)
{
seconde ++
ms = 0;
} 
if (seconde >60)
{
minute ++
seconde = 0;
}
if (minute >60)
hour ++
minute = 0;
}
if (hour >24)
{
hour = 0;
}

i am like 20% sure this is going to work but ok it's something to work on

[SuperBatXS]

Hey guys,
1000th post!!!! YES! Anyways, i need help with this code:

	{	
		ScePspFVector3 move = { 0.0f, 0.0f, -3.0f };
		
		sceGumTranslate( &move );
		sceGumRotateY( rquad );
		double PI = 3.14159265358979323846264338327;
		sceGumRotateY(90*(PI/180.0f));
	}

This code doesn't seem to work. It keeps rotating the cube. If i use this:

	{	
		ScePspFVector3 move = { 0.0f, 0.0f, -3.0f };
		
		sceGumTranslate( &move );
		double PI = 3.14159265358979323846264338327;
		sceGumRotateY(90*(PI/180.0f));
	}

This code doesn't do anything. What do i use to make it rotate the cube (rquad) exactly 90 degrees left or right using radians?

[michaelp]

where is this precompiled environment

Can anyone help?

[michaelp]

thanks
i won't need to use anything else will i?
this is all i need for developing in C

edit: got an error when downloding it

[the_darkside_986]

michaelp, I installed cygwin and toolchain on a lab pc at school on to my jumpdrive and then took it home and copied it to my own Win XP box. Trying to run things compiled for XP on 9x causes problems. But it is good if you found a solution for your problem.
