Auto swap fuel tanks with FSUIPC?

[St54Kevin]

Hey guys,

 

So i wanted to create a script that changes over to the next fuel tank automatically when a specific fuel quantity is left in the mains. I thought FSUIPC might be a good way to do it. But I´ve never worked with it other than as an API to 3rd party tools. How do I approach this?

 

Thanks

First, look for the offsets which hold the fuels tank quantities - you probably want to use the fuel tank level offsets starting at 0x0B74 or 0x1244 (not sure why these are duplicated....). I would monitor them first (using Log =>Offsets) to verify that they are changing as expected. Then create a lua script and use event.offset to receive the level every time it changes. When it reaches a certain level, you can then send the control (using ipc.control) to switch fuel tanks, and maybe also start monitoring the level in that tank as well to switch to the next tank when the level drops below a certain quantity / %age - you can so this for as many tanks that are available. See the FSUIPC Lua Library document for details on how to use these functions.

Note also that the script should be auto-started from your FSUIPC7.ini, most probably only in the profile for the aircraft for which you want to use the script. See the Advanced User guide for automatic running of Luas.

Thanks, maybe I need to emphasize it more: I have NEVER actively used FSUIPC. Do you have a good source on how to start in general?

Do you have a license? You need a registered version for the lua facilities - if you have not purchased yet, please try the trial license, available here:

Use the provided resources - the documentation that comes with FSUIPC (there is also a zip file containing example lua plugins), and the forums - you can look in the FAQ sub-forum and the User Contributions sub-forum for lua scripts that others have provided.

Thanks will have a look on all that
