Minecraft is filled with various blocks that players can discover and create in their survival worlds. However, as a sandbox game, certain blocks can only be accessed when cheats are enabled and commands are utilized. One such block is the command block, obtainable exclusively through commands. This block is used to execute specific commands automatically whenever a redstone signal is received.
There are three distinct types of command blocks available in Minecraft, categorized by their execution frequency and triggering conditions: impulse, chain, and repeating.
Understanding Impulse, Chain, and Repeating Command Blocks in Minecraft
Impulse Command Block
As previously mentioned, a command block is used to automatically perform commands in a Minecraft world, eliminating the need for players to enter them manually in chat. Players can acquire a command block using the “/give”command.
Essentially, the impulse command block is the most basic type, executing a command only once each time it is activated. It will not repeat the command execution unless it receives another activation via a redstone signal, whether triggered manually or through a contraption.
Chain Command Block
A chain command block is a specialized type that executes its command once each time it is triggered by another command block or a redstone signal. However, it must be activated at least once prior to detecting triggers from adjacent command blocks.
After a command block processes its command (regardless of whether it succeeds or fails), it will trigger any chain command blocks it is adjacent to, provided those are in conditional mode unless altered to unconditional.
Repeating Command Block
As the name suggests, a repeating command block executes its command repeatedly on each game tick while activated, specifically in Minecraft Java Edition. In Bedrock Edition, it can execute a command more frequently than a single game tick as long as it remains active.
Importantly, this command block is not influenced by random tick speed; players can modify this with the command “/gamerule randomTickSpeed”. Instead, its operation is based on the game’s standard tick rate of 20 ticks per second, allowing a repeating command block to execute a command up to 20 times every second when active.
