# Keyboard Detector Command Guide *Advanced keyboard event detection in Minecraft for all keys!* ## Command Overview | Command | Functionality | Key Parameters | |---------------|-----------------------------------|------------------------------| | `iskeydown` | Single key press detection | ``, `` | | `matchgroup` | Multi-key combination detection | `` | | `iskeytapped` | Instant Multi-key combination detection | `` | | `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 ````command /keyboarddetector iskeydown ```` |Parameter | Description | Example Values | |------------|----------------|-----------------| | `` | Target player selector | @p, @a[limit=1], @e[type=player,limit=1]| | `` | ASCII code of the key to detect | 49 | | `` | Persistent state mode (true/false) | true, false | ### Usage Examples #### Standard mode: ```command /keyboarddetector iskeydown @p 49 false ```` Detects long-press of key '1'. #### Persistent mode: ````command /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 ````command /keyboarddetector matchgroup ```` ### Parameters |Parameter | Description | Example Values | |------------|----------------|-----------------| | `` | Target player selector | @p, @a[limit=1], @e[type=player,limit=1]| | `` | Comma-separated ASCII codes | 49,50,51 | ### Usage Examples ```command /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 ````command /keyboarddetector iskeytapped ```` ### Parameters |Parameter | Description | Example Values | |------------|----------------|-----------------| | `` | Target player selector | @p, @a[limit=1], @e[type=player,limit=1]| | `` | Comma-separated ASCII codes | 49,50,51 | ### Usage Examples ```command /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: ````command /keyboarddetector iskeydown @p 49 true ```` 2. After keys are pressed, signal stays active 3. Reset detection state **(must with conditional statement)**: ````command /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 `` 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. ### ASCII Key Reference Table | Key | ASCII Code | Key | ASCII Code | |--------------|------------|-------------|------------| | **Numbers** | | **Letters** | | | 0 | 48 | A | 65 | | 1 | 49 | B | 66 | | 2 | 50 | C | 67 | | 3 | 51 | D | 68 | | 4 | 52 | E | 69 | | 5 | 53 | F | 70 | | 6 | 54 | G | 71 | | 7 | 55 | H | 72 | | 8 | 56 | I | 73 | | 9 | 57 | J | 74 | | | | K | 75 | | | | L | 76 | | | | M | 77 | | | | N | 78 | | | | O | 79 | | | | P | 80 | | | | Q | 81 | | | | R | 82 | | | | S | 83 | | | | T | 84 | | | | U | 85 | | | | V | 86 | | | | W | 87 | | | | X | 88 | | | | Y | 89 | | | | Z | 90 | | | | | | | **Functions**| | **Special** | | | F1 | 112 | Space | 32 | | F2 | 113 | Enter | 13 | | F3 | 114 | Esc | 27 | | F4 | 115 | Tab | 9 | | F5 | 116 | Caps Lock | 20 | | F6 | 117 | Shift | 16 | | F7 | 118 | Ctrl | 17 | | F8 | 119 | Alt | 18 | | F9 | 120 | Backspace | 8 | | F10 | 121 | Delete | 46 | | F11 | 122 | Insert | 45 | | F12 | 123 | Home | 36 | | | | End | 35 | | | | Page Up | 33 | | | | Page Down | 34 | | | | Arrow Up | 38 | | | | Arrow Down | 40 | | | | Arrow Left | 37 | | | | Arrow Right | 39 | **Notes**: - Lowercase letters: a=97, b=98 ... z=122 - Numeric keypad: 0=96, 1=97 ... 9=105 - Case sensitive (A=65 vs a=97) - Full reference: [ASCII Table](https://www.asciitable.com)
