peripheral.find
From ComputerCraft Wiki
Function peripheral.find | |
Introduced by ComputerCraft 1.6, returns a list of handles for connected peripherals that match the supplied type (essentially performing as a filtered version of peripheral.wrap()). If multiple peripherals are found, they are all returned as separate values, in the same order peripheral.getNames() returns. A custom function may additionally be passed as a parameter - if it's supplied, each matching peripheral's name and handle will be passed to it during the search, and they'll only be included in the final results if it returns true. | |
Syntax | peripheral.find(string type [, function fnFilter( name, object )]) |
Returns | table handle1, table handle2, ... handles to peripherals of the given type |

Examples
Example | |
Finds a monitor and writes 'Hello' on it. | |
Code |
local monitor = peripheral.find("monitor") if monitor then monitor.write("Hello") end |
Output | If there is a monitor connected 'Hello' will be written on it. |
Example | |
Finds 2 advanced monitors and writes 'Hello' on the first and 'World' on the second. | |
Code |
local mon1, mon2 = peripheral.find("monitor", function(name, object) return object.isColour() end) if mon1 then mon1.setTextColour(colours.blue) mon1.write("Hello") end if mon2 then mon2.setTextColour(colours.red) mon2.write("World") end |
Output | If it finds 1 advanced monitor, 'Hello' will be written on it. If it finds 2 advanced monitors, 'Hello' will be written on the first and 'World' on the second. |
