user.lua initialising question

[Damlimey 0]

Hi all,

I think this is a simple question for all you experts out there.

I would like to have an 'initial state' which presets several switch/variable conditions when I load specific aircraft. Because this will not be triggered by a switch preferably, I am assuming that this should be done by the user.lua file. If that is the case, could somebody please tell me how to code this, let's say it's a one off toggle of a fuel valve.

The only way I have achieved this as a proof of theory was to use the LibUserTimer but obviously, that just kept repeating the toggle on/off. So, my question is specifically; how do I code the user file to perform the function once only when it is loaded?

Big thanks in advance to you all,

D
