Does any one here have some TuT on how to struct ZOPK or ZSOPK and how to update them

for(int i = 0; i < 32; i++)
{
	if(!g_pBase->player || !g_pBase->local) break;
	CPlayer* pPlayer = g_pBase->player[i];
	CPlayerInfo *pInfo = GetPlayerInfo(i) ;

	if(pInfo && pPlayer)
	{
		if(PlayerOPK == 1)
		{
			NoBound = 1;
			if( pInfo->health > 0 )
			{
				pPlayer->pos1 = 0;
				pPlayer->pos2 = 0;
				pPlayer->pos3 = 0;	
			}
		}
	}
}
