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:
 * For the player, so that they can keep all of their valuables when they die:
 * To stop TNT from exploding:
 * To make it so the player can't get health back from eating (only from regeneration or healing potions, or golden apples):

Additional behavior
This section is dedicated to explaining more complex behaviors of certain gamerules.
 * When true, the Bad Omen effect is not removed from a player when entering a village.
 * Stops a raid if set to true while a raid is in progress, but the existing raid mobs do not despawn.
 * When false, items cannot be removed from item frames.
 * Affects only natural mob spawning. Mobs from structures, spawners, and events still spawn when set to false.
 * When false, containers still drop their contents, but not themselves.
 * Shulker boxes do not drop anything, causing the items in them to be lost.
 * When false, destroying an armor stand does not drop it nor any armor it had equipped.
 * When false, the player will still lose air, but will not take damage when the air is depleted.
 * When false, prevents:
 * All mobs from:
 * Trampling crops.
 * Picking up items.
 * Blazes from creating fire or lighting campfires.
 * Creepers from destroying blocks when they explode, although they still damage entities.
 * The ender dragon from destroying blocks, causing it to just fly through them instead.
 * Endermen from picking up or placing blocks.
 * Foxes from picking sweet berries from a sweet berry bush.
 * Ghast fireballs from exploding blocks and creating fire. They will still damage entities.
 * Rabbits from eating carrot crops.
 * Ravagers from destroying crops and leaves.
 * Sheep from turning grass blocks into dirt, but does not prevent the regrowth of wool.
 * Snow golems from creating snow trails.
 * Villagers from farming and picking up items. However, they can still open doors and throw items.
 * The wither and its heads from destroying blocks with their explosions. Entities will still be damaged, and wither roses will drop as an item.
 * Zombies from breaking doors.
 * Has no effect on the player.
