| This API requires the use of a wrapped peripheral! This API does not behave like a regular API, to use it you must first wrap the peripheral and call the methods on the wrapped object. For more information see this page.
|
The Command Block API allows you to run commands in a Command Block, using it as a peripheral. (The peripheral can only be used if allowed in the config, which disables it by default.) Under CC 1.7 or later, it may be easier to use a Command Computer.
API
Functions exposed by the Command Block, where "commandBlock" is a wrapped Command Block:
 Command Block (API) | ||
|---|---|---|
| Function | Return values | Description |
| commandBlock.getCommand() | string command | Returns a string containing the command currently inside the Command Block. |
| commandBlock.setCommand(string command) | nil | Sets the command in the Command Block to command. This does not run it. |
| commandBlock.runCommand() | boolean success [, string error] | Runs the command inside the Command Block previously set by manually editing it or by using commandBlock.setCommand(). |
Usage
All Command Block functions are to be used after wrapping the block as a peripheral. Example:
local commandBlock = peripheral.wrap("left") commandBlock.setCommand("time set 1000") commandBlock.runCommand() local currentCommand = commandBlock.getCommand()
