|Repeating Command Block|
|Type of Block||Solid Block, Redstone|
|Tool Used||None (cannot be destroyed outside of Creative Mode)|
|Data Values||Hex: 89|
The Repeating Command Block is a redstone-powered block that was made available in the 1.9 patch for Minecraft. The Repeating Command will perform server commands over and over again when attached to a redstone circuit. This block cannot be crafted and only server administrators are allowed to place them. Command blocks can only be obtained when cheats are activated, and can still only be used in creative mode, preventing survival players in a server from accessing "staff" abilities. Repeating Command blocks are invincible outside of creative mode. With Repeating Command blocks, one can preform commands that players can not preform.
To get a repeating command block using cheats, type
/give @p minecraft:repeating_command_block <amount>.
When attached to a redstone circuit, or set to "Always" instead of "Needs Redstone," the Repeating Command Block can perform a variety of server commands, such as changing the difficulty or giving players items. There are also gamerules, which are unique commands over and over again.
This table shows the list of gamerules.
|Gamerule||What it does|
|commandBlockOutput||Enables/disables text output of command block commands to console|
|Enables/disables fire spread.|
|doMobLoot||Enables/disables mob drops.|
|doMobSpawning||Enables/disables the spawning of mobs unless one wants them to ex: eggs and mob spawners will still spawn mobs.|
|doTileDrops||Enables/disables blocks dropping items when broken (includes TNT destroying blocks).|
|keepInventory||Enables/disables keeping inventory on death.|
Enables/disables creepers, ghasts, and Wither blowing up blocks, endermen picking up blocks and zombies breaking doors.
|doNaturalRegeneration||Enables/disables regenerating health when hunger is full or close to full.|
Gamerules are case sensitive.
One must type in /gamerule before the name of the actual gamerule, and true/false tells whether one wants to disable the gamerule (false), or enable it (true).
An example of a gamerule command is
/gamerule mobGriefing true.
This table shows that commands can be restricted to players on the server.
An example of a command is:
/give @p minecraft:cobblestone 64, which will give the nearest player a stack of Cobblestone over and over again until the repeating command block is destroyed or is not powered..
