Synopsis #

Copy a 16-bit sprite/image to the VRAM buffer.

Definition #

void CopySprite(color_t* sprite, int x, int y, int width, int height) {
   color_t* VRAM = (color_t*)GetVRAMAddress();
   VRAM += LCD_WIDTH_PX*y + x;
   for(int j=y; j<y+height; j++) {
      for(int i=x; i<x+width; i++) {
         *(VRAM++) = *(sprite++);
      }
      VRAM += LCD_WIDTH_PX-width;
   }
} 

Inputs #

• color_t* sprite: The sprite data (from SourceCoder?)
• int x: X-coordinate of top-left of sprite
• int y: Y-coordinate of top-left of sprite
• int width: Width of sprite, in pixels
• int height: Height of sprite, in pixels

Outputs #

Sprite drawn to VRAM

SourceCoder can be used to convert .png, .bmp, and .gif images to arrays that you can use with this routine.
