Setting up force feedback

Force feedback is currently only supported on Linux.

Prerequisites

• a steering wheel supporting constant force effects (like a Logitech Momo Racing force feedback steering wheel)
• Linux
• HID_FF is enabled in your kernel
• your device's USB ID is in kernel-source/drivers/usb/input/hid-ff.c
• the ff-utils test program ffcfstress works for you. Note the device name you use with this program (should be /dev/input/eventX).
• write permission to /dev/input/eventX
• VDrift SVN r1547 or later

If you need to recompile your kernel to enable force feedback, you can have a look here Enabling force feedback in kernel

Enabling force feedback in VDrift

Once you've met the prerequisites, recompile vdrift like this:

scons force_feedback=1

Now open your VDrift.config. Find the section [ joystick ] and add the following line to the joystick section somewhere:

ff_device = /dev/input/event0

Change event0 to whatever device you should use (the one that worked with ffcfstress).

Start up VDrift. The console will print whether or not force feedback initialization succeeded. Start a practice game. You should feel a force effect on your steering wheel based on the aligning moment force from the front tires.
