Result

 * Fails if rule name is not defined and value is not provided (i.e., attempting to query an undefined game rule), or if "rule name is not a predefined game rule.
 * On success, returns the value of the game rule (if value is not provided) or sets the game rule to the specified value (if value is provided).

Examples

 * To stop the day-night cycle:
 * To stop natural healing:
 * To stop creepers, ghasts and other mobs from modifying blocks:
 * To stop the natural cycle of weather:
 * To keep all of your valuables when you die:
