Wwise: SIMVAR_GROUND_VELOCITY

I found out in Wwise that the simvar ‘SIMVAR_GROUND_VELOCITY’ (and others) only returns the value of the user plane. Is it possible to make it so I can read the value of AI aircraft, like I do for TURB_ENG_N1 and TURB_ENG_N2?

What’s this? Nobody?

Trying again, within Wwise you can use Simvars to control your sounds. As I only make sounds for AI aircraft, I would like to use SIMVAR_GROUND_VELOCITY to vary some sounds for ground roll. But it turns out the option uses the Simvar of the user aircraft instead of the AI aircraft that is producing the sound. Can this please be fixed.

Hello @MaVe1628,

Sadly, we do not expose this Simvar as an RTPC in Wwise for now.

If you want, you can create an Idea here on the forum to let us know your needs more specifically.

Regards,

Alexandre

Why do you use the same Simvars in your Wwise AI aircraft example then?

Indeed, it shouldn’t be used. I am logging a bug about this issue. Thanks.

@MaVe1628 I was able to get this working in the //42 “JuiceGoose” on AI vehicles. On the AI XML:

  <Sound WwiseEvent="GROUND_ROLL" SimVar="GROUND VELOCITY" Units="KNOTS" Index="0" FadeOutType="2" FadeOutTime="0.5" WwiseData="true" ContinuousStopDelay="1.5" >
    <WwiseRTPC SimVar="GROUND VELOCITY" Units="KNOTS" Index="0" RTPCName="SIMVAR_GROUND_VELOCITY" />
  </Sound>

Thanks a lot! That was it, didn’t think we had to put these variables in the soundai.xml. Great heads up.
