Anyone seeing this yet? http://sourceforge.net/p/hapticsforfg/code/HEAD/tree/ It would be very interesting to have Force Feedback on FG,since I don't know any sim in development having FF. — Poomklao Teerawattanaprapha (Dec 29th, 2015). [Flightgear-devel] Feature commit request:Force feedback.

Status

For the last few days I have coded force feedback support for FlightGear. It currently works, I have implemented control surface loading (for jsbsim), pilot g forces and stick shaker. Currently the system is so that I have external app which uses SDL 1.3 to handle the ff effects, so it should be portable quite easily. That program communicates with FG through telnet, and some nasal/xml magic on FG does the rest. Here's a screenshot of the configuration options (from which most do not yet work, but you get the idea): (see the linked image) I will support: multiple devices, autocenter, control surface forces, pilot g forces and stick shaker at least. And all effects can be disabled, or disabled/enabled on some devices, and also axes should be configurable. Now, the problem is that telnet interface is way too slow, the forces are updated once every 1 or 2 seconds, which is awfull. But I still don't know beforehand which properties to pull, so generic I/O is not good either. Does anyone have any ideas on how to solve this? — Zan (Dec 19th, 2011).  . (powered by Instant-Cquotes)
