I can't get it to work.

I want to assign a keyboard key to wheel axis, but it's not even available.

Only pedals are available....

Is there a way to assign a kbd key to "wheel left" and another key to "wheel right"?

Hello,

I will consider adding this in a future release.

In the meantime, you can try using macro to achieve this. Bind an axis to the wheel and generate axis movement with a button.

Hello,

Im not a Steering Wheel expert as Matlo but because he's on vacation now I'll try to help.

Please open configuration with text editor, find these lines

Code: Select all

<axis_map>
...
</axis_map>

Add following code inside <axis_map> to make it look like that

Code: Select all

<axis_map>
...
<axis id="rel_axis_0-" label="">
          <device type="keyboard" id="0" name=""/>
          <event type="button" id="a"/>
</axis>
<axis id="rel_axis_0+" label="">
          <device type="keyboard" id="0" name=""/>
          <event type="button" id="d"/>
</axis>
</axis_map>

In theory it should force GIMX to bind keyboard A and D keys to wheel axis even if this option does not seem to be available in gimx-config.

If it doesn't work then make sure rel_axis_0 is correct axis name for wheel axis, you can check that also inside <axis_map>, there should be something like that

Code: Select all

<axis id="rel_axis_0" label="wheel">
          <device type="joystick" id="0" name="Logitech Driving Force GT USB"/>
          <event type="axis" id="0" dead_zone="0" multiplier="0.0039" exponent="1.00" shape=""/>
        </axis>

It means that rel_axis_0 is the wheel axis and if you add lines I wrote before it should work.

Regards,
Daniel

EDIT:: Ah it looks like Matlo replied while I was writing this post. @Matlo could you please check if my idea could work? It's simplier than making a macro.

Yes, it may work.

After reading your valuable reply, my <axis_map> structure was changed to this:

Code: Select all

      <axis_map>
        <axis id="rel_axis_0-" label="">
          <device type="keyboard" id="0" name=""/>
          <event type="button" id="a"/>
		</axis>
		<axis id="rel_axis_0+" label="">
          <device type="keyboard" id="0" name=""/>
          <event type="button" id="d"/>
		</axis>
		<axis id="rel_axis_0" label="wheel">
          <device type="joystick" id="0" name="Logitech G27 Racing Wheel USB"/>
          <event type="axis" id="0" dead_zone="0" multiplier="0.0039" exponent="1.00" shape=""/>
        </axis>
        <axis id="abs_axis_17" label="gas">
          <device type="joystick" id="0" name="Logitech G27 Racing Wheel USB"/>
          <event type="axis" id="1" dead_zone="0" multiplier="0.008" exponent="1.00" shape=""/>
        </axis>
        <axis id="abs_axis_18" label="brake">
          <device type="joystick" id="0" name="Logitech G27 Racing Wheel USB"/>
          <event type="axis" id="2" dead_zone="0" multiplier="0.008" exponent="1.00" shape=""/>
        </axis>
        <axis id="abs_axis_19" label="clutch">
          <device type="joystick" id="0" name="Logitech G27 Racing Wheel USB"/>
          <event type="axis" id="4" dead_zone="0" multiplier="0.008" exponent="1.00" shape=""/>
        </axis>
      </axis_map>

But it's not working....

About the macro suggestion, I didn't find any mention to wheel axis in the wiki, only mouse and joystick axis are specified there....

Am I missing something?

You shouldn't change wheel axis number but change my code to match the real wheel axis number. I tested it and it worked, with a gamepad at least. Could you please send us the whole config before changes?

Axises are same for mouses, joysticks and wheels so you can use Macros system.

Will post the whole config as soon as I can.

Thanks!

This should be fixed in GIMX 7.8: viewtopic.php?f=2&t=2704
Feedback is very welcome!
