Do you have to take the ball back after a missed shot playing half court?

There are two methods of playing a half-court game.

One method is that if the ball is missed but hits the rim or backboard, the opposite team (the team that shot the ball can rebound and shoot as they please) must take the ball back. If the ball is missed and hits nothing, then the opposing team does not have to take the ball back.

The second method is the same except that the ball must be taken back under all circumstances for the opposing team, should they gain possession of the ball.
