It is the result of having a star hit with**	a photon torpedo.  There are several things which may happen.**	The star may not be affected.  It may go nova.  It may turn**	into a black hole.  Any (yummy) it may go supernova.****	Stars that go nova cause stars which surround them to undergo**	the same probabilistic process.  Klingons next to them are**	destroyed.  And if the starship is next to it, it gets zapped.**	If the zap is too much, it gets destroyed.*/nova(x, y)int	x, y;{	register int		i, j;	register int		se;	if (Sect[x][y] != STAR || Quad[Ship.quadx][Ship.quady].stars < 0)		return;	if (ranf(100) < 15)	{		printf("Spock: Star at %d,%d failed to nova.\n", x, y);		return;	}	if (ranf(100) < 5)		return (snova(x, y));	printf("Spock: Star at %d,%d gone nova\n", x, y);	if (ranf(4) != 0)		Sect[x][y] = EMPTY;	else	{		Sect[x][y] = HOLE;		Quad[Ship.quadx][Ship.quady].holes += 1;	}	Quad[Ship.quadx][Ship.quady].stars -= 1;	Game.kills += 1;	for (i = x - 1; i <= x + 1; i++)	{		if (i < 0 || i >= NSECTS)			continue;		for (j = y - 1; j <= y + 1; j++)		{			if (j < 0 || j >= NSECTS)				continue;			se = Sect[i][j];			switch (se)			{			  case EMPTY:			  case HOLE:				break;			  case KLINGON:				killk(i, j);				break;			  case STAR:				nova(i, j);				break;			  case INHABIT:				kills(i, j, -1);				break;			  case BASE:				killb(i, j);				Game.killb += 1;				break;			  case ENTERPRISE:			  case QUEENE:				se = 2000;				if (Ship.shldup)					if (Ship.shield >= se)					{						Ship.shield -= se;						se = 0;					}					else					{						se -= Ship.shield;						Ship.shield = 0;					}				Ship.energy -= se;				if (Ship.energy <= 0)					lose(L_SUICID);				break;			  default:				printf("Unknown object %c at %d,%d destroyed\n",					se, i, j);				Sect[i][j] = EMPTY;				break;			}		}	}	return;}
