|—————|———————————–|——————————|
| 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 key 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

1. 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.
