Hi, im just started again with ds development.

Everything seems to been changed a littlebit.

Im now trying to make a puzzle game with sprites, but 3 months before it was realy easy for me to make a game with sprites.

But now i can't even get sprites on the screen??

So i used an example named : Complex_2d from devoto.

Ok got the sprites working now! but only on hardware!!

When i start my compiled program on my hardware ds then it runs, but on the emulator it wont work anymore.

a few months ago i used it to test my codes, because writing it the whole time to my flashcard takes a lot of time.

But now it won't work anymore on dualis???

What's going wrong with the new development area???? I really don't know??

here's my code :

Code:

#include <stdlib.h>
#include <nds.h>

// these files are generated automatically by the bin2o rule
#include "ballpalette_bin.h"
#include "balldata_bin.h"

#define NUM_SPRITES 36

sSpriteEntry OAMCopySub[128];

//simple sprite struct
typedef struct {
int x,y;          //location
int dx, dy;       //speed
sSpriteEntry* oam;
int gfxID;          //graphics lovation
}Sprite;

//---------------------------------------------------------------------------------
void MoveSprite(Sprite* sp) {
//---------------------------------------------------------------------------------
int x = sp->x >> 8;
int y = sp->y >> 8;

sp->oam->attribute[1] &= 0xFE00;
sp->oam->attribute[1] |= (x & 0x01FF);

sp->oam->attribute[0] &= 0xFF00;
sp->oam->attribute[0] |= (y & 0x00FF);

}

//---------------------------------------------------------------------------------
void initOAM(void) {
//---------------------------------------------------------------------------------
int i;

for(i = 0; i < 128; i++) {
   OAMCopySub[i].attribute[0] = ATTR0_DISABLED;
}
}

//---------------------------------------------------------------------------------
void updateOAM(void) {
//---------------------------------------------------------------------------------
unsigned int i;

for(i = 0; i < 128 * sizeof(sSpriteEntry) / 4 ; i++)
{
   ((uint32*)OAM_SUB)[i] = ((uint32*)OAMCopySub)[i];
}
}

//---------------------------------------------------------------------------------
void irqVBlank(void) {
//---------------------------------------------------------------------------------
IF = IF;
}

//---------------------------------------------------------------------------------
int main(void) {
//---------------------------------------------------------------------------------

uint16* back = VRAM_A;
uint16* front = VRAM_B;

Sprite sprites[NUM_SPRITES];

int i, j;
int ix = 0;
int iy = 0;
int screen = 1;
uint16* map0 = (uint16*)SCREEN_BASE_BLOCK_SUB(1);
uint16* map1 = (uint16*)SCREEN_BASE_BLOCK_SUB(2);
uint16 red;

//turn on the power to the system
powerON(POWER_ALL);

//set main display to render directly from the frame buffer

//vram banks are somewhat complex
vramSetMainBanks(VRAM_A_LCD, VRAM_B_LCD, VRAM_C_SUB_BG, VRAM_D_SUB_SPRITE);

//irqs are nice
irqInit();
irqSet(IRQ_VBLANK, irqVBlank);

// Sprite initialisation
for(i = 0; i < 256; i++)
   SPRITE_PALETTE_SUB[i] = ((u16*)ballpalette_bin)[i];
/*

      if(sprites[i].y < (1<<8) || sprites[i].y > (182 << 8))
         sprites[i].dy = -sprites[i].dy;

      //reposition the sprites
      MoveSprite(&sprites[i]);
   }


   swiWaitForVBlank();

   updateOAM();
/*
   //flip screens
   if(screen) {
      videoSetMode(MODE_FB1);
      front = VRAM_B;
      back = VRAM_A;
      screen = 0;
   } else {
      videoSetMode(MODE_FB0);
      front = VRAM_A;
      back = VRAM_B;
      screen = 1;
   } */
}
return 0;
}

i only get a dark screen with a block on topleft???

Hope you guys know the problem??

thanx anyway!!
