Command Block Behavior

2. Key Combination Detection: /keyboarddetector matchgroup

Functionality

Detects simultaneous pressing of multiple keys (independent key processing).

Command Syntax

/keyboarddetector matchgroup <PlayerID> <KeyAsciiList> <keepStatic>

Parameters

Usage Examples

/keyboarddetector matchgroup @p 49,50,51

Command Block Behavior

• In repeating command blocks:
  • 🔴 Key pressed: Returns true and activates redstone signal
  • ⚪ Key released: Returns false and deactivates redstone signal

3. Instant Combination Detection: /keyboarddetector iskeytapped

Functionality

Detects exclusively the moment of key press for multiple keys (independent key processing).

Command Syntax

/keyboarddetector iskeytapped <PlayerID> <KeyAsciiList> <keepStatic>

Parameters

Usage Examples

/keyboarddetector iskeytapped @p 49,50,51

Detects exclusively the moment of pressing keys '1', '2', '3'.

Command Block Behavior

• In repeating command blocks:
  • 🔴 Key pressed: Returns true and activates redstone signal only at press moment
  • ⚪ Key hold: Returns false and deactivates redstone signal (Difference from /keyboarddetector matchgroup)
  • ⚪ Key released: Returns false and deactivates redstone signal

4. State Reset Command: /keyboarddetector flush

Functionality

Clears persistent key states created by iskeydown with keepStatic=true

Usage Scenario

1. Persistent mode activated:

   /keyboarddetector iskeydown @p 49 true

2. After keys are pressed, signal stays active

3. Reset detection state (must with conditional statement):

   /keyboarddetector flush

Effects

♻️ Resets all detection states

🚦 Requires new key combination press to reactivate

Attention

❗ When more than 1 command blocks execute /keyboarddetector matchgroup, ensure all <AsciiList> contain no duplicate values. Otherwise, only one key event can trigger.

❗ Do not use /keyboarddetector flush without conditional statement. Otherwise, all detection subcommands become unavailable.
