Ok here is what I would like to accomplish and what I did right now to try to get there.

All I want to do is play a MP3 at a specified time, like and alarm, then stop and continue what I was doing.

Code:

void AlarmManager::PlaySound()
{
   pspAudioInit();
   
   MP3_Init(1);
   MP3_Load("data/sound/Alarm.mp3");
   MP3_Play();
   
                while(int i = 1)
                {
                   if(MP3_EndOfStream() == 1)
      {
      MP3_Stop();
      i = 0;            
       }
   }
   MP3_FreeTune();
}


Right now all it does is play the sound then stops. The PSP doesn't go back and then it' shuts down.

I call that method from the main.

2- I Display a clock at the top of my screen
Code:

   pspTime time;
   
   while(isrunning){
      sceRtcGetCurrentClockLocalTime(&time);
      
      char timeText[8];

      SDL_BlitSurface(background, NULL, ecran, &background_position);
      SDL_FreeSurface(textTime);
      
      snprintf(timeText, 8, "%02i : %02i", time.hour, time.minutes);
      SDL_Surface *textTime = TTF_RenderText_Shaded(timeFont, timeText, couleurblanc, couleurnoir);

       SDL_BlitSurface(textTime, NULL, ecran, &txttime_position);

    }


This is all in my main loop, for some reason the clock shows up for like 2 minutes then dissapear... Can't figure out why!

Cheers

The thread sounds much friendlier now, but sorry, I don't know the answer.
Actually I just wanted to point out, that it's not very nice to bump a thread that soon (not even 1 day) after you've postet your question. If no one replies, then maybe no one knows.

Thank you for your answer Mihawk.

But I would like to know the "correct" and polite way to post over here, cause it seems every forums has his own way or rulke about that, and from now on I would like to be able to post the correct way here.

And I'm sorry if I bumped that early, but I am stuck and I wanted to move foward with that. Anyways sorry for all that!!

Thank anyways

Are you running in psplink? If the PSP is shutting down, you are likely getting an exception and you can just find out where.

You have

Code:
      SDL_FreeSurface(textTime);


But textTime seems to be set AFTER this point. Where's the check to see if textTime has yet been initialized? Maybe it's in another part of the code, but we can't see that from the two snippets you posted.

Two things I'd do - first, turn the speed down. You don't need 333MHz for this. It'd be much better to crank the speed down as far as you could go and still play an mp3 so it saves battery life. Second, I'd put a delay after the flip. There's no reason to be going through the loop more than a few times per second.

Code:
   sceKernelDelayThread(250*1000);


That would delay the program so that you only did four loops per second. It's possible the unexpected quit is due to calling the flip too frequently.

Thank you for your advice J.F. I would like to point out one little small problem. Now with the reduce speed the mouse, that is used as a pointer device to select stuff, is really slow on the screen and doesn't run smoothly... Is there anything to do with that?

BTW It seems to have solved the problem I had with the clock disapearing.

Probably had to do with calling flip to often. I'm not familiar with SDL, but there's probably a function in it you could call before or after flip that would handle that issue.

As to the mouse speed, the delay time I gave was for 4 times per second. I didn't notice you had a mouse in there. You might bump that a bit higher - maybe 20 or 30 times per second. The delay value is microseconds.

Just to keep you posted on my problem J.F. I figured out a way to bypass the sceKernlDelayThread by adding a condition like so

Code:

    while(isrunning)
    {      
      
        sceRtcGetCurrentTick(&CurTick);
      
        if (sceRtcCompareTick(&CurTick, &CmpTick) >= 0)
        {
                      SDL_FreeSurface(textTime);
                      snprintf(timeText, 8, "%02i : %02i", time.hour, time.minutes);
         
                      textTime = TTF_RenderText_Shaded(timeFont, timeText, white, black);

                      sceRtcGetTick(&time, &CmpTick);
                      sceRtcTickAddMinutes(&CmpTick, &CmpTick, 1);
                      SDL_BlitSurface(textTime, NULL, ecran, &txttime_position);
        }

    }


I have no clue if it's the perfect way to do it but right now it works.

Thank you for your help

There's no such thing as the "perfect way". :) Sometimes, you're looking for an optimal solution, while other times you're looking for something more simple and maintainable. The above is simple to follow - each time through the loop, check if a minute has gone by. If so, add another minute and update the clock time. Waiting an odd number of microseconds doesn't lend itself to understanding why you were waiting without a comment to accompany it.

So programmers don't use terms like "perfect" - leave that to marketing. Programmers prefer terms like "better", "optimal", "intuitive", "simple", etc. Shades of gray...
