Command Overview

Command	Functionality	Key Parameters
iskeydown	Single key press detection	<KeyAscii>, <keepStatic>

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.
