SetBlockInput(boolean)

grandMA3 User Manual » Plugins » Lua Functions - Object-Free API » SetBlockInput(boolean)
Version 2.1

Description

The SetBlockInput function is an internal function used during the system tests. It stops input from USB-connected keyboards and mouse. The built-in keyboard on some models is internally connected using a USB connection, which is also blocked by this function. The block affects the station where the function is executed.

Important:
Should the station be blocked and cannot be unblocked using a new Lua command, then pressing the keyboard keys A, S, D, and F simultaneously unblock the input again.

Arguments

  • Boolean:
    The boolean indicates if the stations' input should be blocked or unblocked.
    • true (or 1): The station input is blocked.
    • false (or 0): The station input is unblocked.

Return

This function does not return anything.

Example

This example blocks mouse and keyboard input for 10 seconds:

Lua
return function()
-- Set a variable for yield time in seconds
yieldTime = 10
-- Set the block to true
SetBlockInput(true)
-- Wait the [yieldtime]
coroutine.yield(yieldTime)
-- Unblock the station
SetBlockInput(false)
end
