Hello, my group is developing a framework OOP for games, using OSLib.

how I can make a thread using c++ and OSLib?
I need to have a thread carrying my images, sounds, etc. To create a loading system.

This is my function Start:
Code:

void PSPFLoader::Start() {
    LoadThread = sceKernelCreateThread("PSPFLoaderThread", ThreadMetod, 0x10, 0x10000, PSP_THREAD_ATTR_USER, NULL);
   
    if (LoadThread >= 0) {
        sceKernelStartThread(LoadThread, 0, 0);
        SceKernelThreadInfo* info;
        sceKernelReferThreadStatus(LoadThread, info);
        oslDebug("%d", info->status);
    }
    else
        oslDebug("Erro #501");
   
    Started = true;
}






In My other class inherit Loader above:

Code:
AngelLoader::AngelLoader() {
    ThreadMetod = loa;
}
int loa(SceSize args, void *argp) {   
    PSPFResourceManager* r = PSPFResourceManager::getResourceManager();
    oslDebug("PRE1");
    PSPFImage* imagem = new PSPFImage(100, 74, OSL_PF_5551, "Anjo.png");
    imagem->setFormatSheet(50, 74);
    r->AddResource(imagem, "ANJO");
    mywait(1000);
    oslDebug("PRE1 - OK");
   
    PSPFImage* background = new PSPFImage(500, 300, OSL_PF_5551, "fundo.jpg");
    r->AddResource(background, "BACKGROUND");
    mywait(1000);
   
    PSPFSound* musica = new PSPFSound("som.wav", NONE, 1);
    r->AddResource(musica, "SOM");
    mywait(1000);
   
    Mundo* fase1 = new Mundo();
    PSPFWorldManager::getWorldManager()->AddPSPFWorld(fase1);
    PSPFWorldManager::getWorldManager()->setWorldFocus(1);
   
    return 1;
}


But this thread return status 4 (Waiting) or PSP Crash.

I´m try this code below

Code:

#include <oslib/oslib.h>
#include <pspthreadman.h>

PSP_MODULE_INFO("THExample", 0, 1, 1);
PSP_MAIN_THREAD_ATTR(THREAD_ATTR_USER | THREAD_ATTR_VFPU);

bool loaded;
OSL_IMAGE* Image;

int user_main(SceSize args, void *argp) {
      
    Image = oslCreateImage(50, 74, OSL_IN_RAM, OSL_PF_8888);
   oslPrintf("create\n");
    Image = oslLoadImageFile("anjo1.png", OSL_IN_RAM, OSL_PF_8888);
   oslPrintf("loaded\n");
   if (Image == NULL) {
         oslFatalError("Error <#300>");
         return -1;
     }
    loaded = true;
   return 0;
}

int main(SceSize args, void *argp) {
    loaded = false;
   
    oslInit(0);
    oslInitGfx(OSL_PF_8888, 0);
   oslInitConsole();
   oslPrintf("Loading images...");
   
   SceUID thid = sceKernelCreateThread("User Mode Thread", user_main,
            0x11, // default priority
            256*1024, // stack size (256KB is regular default)
            PSP_THREAD_ATTR_USER, NULL);
   
    sceKernelStartThread(thid, 0, NULL);
    sceKernelWaitThreadEnd(thid, NULL);

   while (!osl_quit) {
        oslStartDrawing();
       
        if (loaded) oslDrawImage(Image);
       
        oslReadKeys();
        if (osl_pad.pressed.start) oslQuit();
      
       
        oslEndDrawing();
    }   
   
    oslEndGfx();
    oslQuit();
   
    return 0;
}


oslPrintf is displayed but Image is not drawing.

Your main thread isn't waiting, so the spawned thread doesn't get time to run. The PSP does COOPERATIVE multitasking, not preemptive. Just add something like

Code:
    sceKernelDelayThread(100000);
