If it is not forced out what must happen to a base runner to be called out in softball?

Not sure about all six, but the batter can be out if (s)he bunts foul on strike two (this is actually a strikeout), steps on the plate while bunting the ball, steps on the plate while hitting the ball, hits the ball when it is determined that the batter is out of the batter's box, touches the ball in fair territory with the body while out of the batters box, is hit by a throw to first from behind if not running in the outlined base running area between home and first, is hit by a pitch that is in the strike zone if (s)he intentionally positions a part of the body in a way that results in the ball hitting him/her.
