Penalty standard for walking:
1. has a central foot. When you stand on the ground with your feet and start dribbling, the center foot must not be lifted until the ball is released. The rules for starting dribbling and moving are the same, so I combined them into one rule.
2. When there is no central foot, neither foot can be lifted until the ball is released.
3. When there is a center foot, the player can (lift) or jump up the center foot, but neither foot can fall back to the ground before the ball is released.
4. There is a central foot. When moving, the player can jump (lift) the center foot and land on one foot or both feet at the same time. However, after one or both feet are lifted, neither foot should fall back to the ground until the ball is released.
5. When there is no central foot, you can lift it with one foot or both feet, but you must not fall back to the ground before putting the ball.
