C++ (Cpp) DBuffer Examples

Example #1

File: sectSprites.cpp Project: Angluca/nxengine-libretro

uint8_t *SIFSpritesSect::Encode(SIFSprite *sprites, int nsprites, int *datalen_out)
{
DBuffer buf;
int i, f;

	buf.Append16(nsprites);
	
	for(i=0;i<nsprites;i++)
	{
		buf.Append8(sprites[i].w);
		buf.Append8(sprites[i].h);
		buf.Append8(sprites[i].spritesheet);
		
		buf.Append8(sprites[i].nframes);
		buf.Append8(sprites[i].ndirs);
		
		SaveRect(&sprites[i].bbox, &buf);
		SaveRect(&sprites[i].solidbox, &buf);
		
		SavePoint(&sprites[i].spawn_point, &buf);
		
		SavePointList(&sprites[i].block_l, &buf);
		SavePointList(&sprites[i].block_r, &buf);
		SavePointList(&sprites[i].block_u, &buf);
		SavePointList(&sprites[i].block_d, &buf);
		
		for(f=0;f<sprites[i].nframes;f++)
		{

		}

	if (datalen_out) *datalen_out = buf.Length();
	return buf.TakeData();
