Linux force feedback wheel support

[thelusiv]

jdeneux, I haven't yet created a gain setting for the force-feedback. You could also try turning on stop-and-start to see if that gives you better results. What kind of joystick were you trying to use? Does it work in jstest, jscal, jscalibrator, etc.?

If you're playing with the keyboard I recommend turning on "Button Control Delay" in Options -> Controls. Also turn on the Input Graph in Options -> Display. This will make the keyboard controls much easier to drive with. If they're not already on, also turn on ABS and TCS.

However there should be some noticeable force feedback if you're driving and turning, no matter what gear. I basically kept the same settings that ffcfstress defaulted with - the updates happen at about 25 Hz, the gain is 2.0 because that felt good on my wheel, etc. I'll see if I can make it a little easier to tune, like perhaps you could try chaging line 987 in src/vamosworld.cpp from

Code:

if( ff_update_time >= 40.0 )

to

Code:

if( ff_update_time >= 100.0 )

this would set the updates to happen at 10 Hz instead of 25 Hz, and maybe you won't get the error messages anymore.
