Keyboard Detector Command Guide

Advanced keyboard event detection in Minecraft for all keys!

Command Overview

Command Functionality Key Parameters
iskeydown Single key press detection <KeyAscii>, <keepStatic>
matchgroup Multi-key combination detection <KeyAsciiList>
iskeytapped Instant Multi-key combination detection <KeyAsciiList>
flush Reset key states for subcommand iskeydown None

1. Single Key Detection: /keyboarddetector iskeydown

Functionality

Detects real-time press state of a specific keyboard key.

Command Syntax

/keyboarddetector iskeydown <PlayerID> <KeyAscii>
Parameter Description Example Values
<PlayerID> Target player selector @p, @a[limit=1], @e[type=player,limit=1]
<KeyAscii> ASCII code of the 11key to detect 49
<keepStatic> Persistent state mode (true/false) true, false

Usage Examples

Standard mode:

/keyboarddetector iskeydown @p 49 false

Detects long-press of key '1'.

Persistent mode:

/keyboarddetector iskeydown @p 49 true

If target player have pressed the '1' key, the command block will return true and activate redstone signal constantly (Until /keyboarddetector flush is executed).

Command Block Behavior

Mode Behavior
Standard Mode (keepStatic=false) • Activates signal when all keys are pressed simultaneously
• Deactivates immediately when any key is released
Persistent Mode (keepStatic=true) • Locks signal on first successful detection.
• Maintains activation after keys are released.
• Requires manual flush to reset

2. Key Combination Detection: /keyboarddetector matchgroup

Functionality

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

Command Syntax

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

Parameters

Parameter Description Example Values
<PlayerID> Target player selector @p, @a[limit=1], @e[type=player,limit=1]
<KeyAscii> Comma-separated ASCII codes 49,50,51

Usage Examples

/keyboarddetector matchgroup @p 49,50,51

` Detects simultaneous press of keys '1', '2', '3'.

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 Key Combination Detection: /keyboarddetector iskeytapped

Functionality

Detect solely the instant when the key is pressed for multiple keys. (independent key processing).

Command Syntax

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

Parameters

Parameter Description Example Values
<PlayerID> Target player selector @p, @a[limit=1], @e[type=player,limit=1]
<KeyAscii> Comma-separated ASCII codes 49,50,51

Usage Examples

/keyboarddetector iskeytapped @p 49,50,51

Detects solely the instant when the key '1', '2', '3' are pressed.

Command Block Behavior

  • In repeating command blocks:
    • 🔴 Key pressed: Returns true and activates redstone signal solely the instant when the key is pressed.
    • ⚪ Key hold: Returns false and deactivates redstone signal. (Different 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

  1. After keys are pressed, signal stays active

  2. 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 are exetuting /keyboarddetector matchgroup, make sure all <AsciiList> must not contain any duplicate values. Otherwise, only one of the key events can be triggered.

❗ Do not use /keyboarddetector flush without conditional statement. Otherwise, all subcommands for decection won't be available.
