Hi there,

I'm trying to use Wwise Meter to update an RTPC and translate that into a visual element in Unity. In the Wwise Profiler, I can clearly see the RTPC is updating for the game objects as intended, but when using AkSoundEngine.GetRTPCValue() on the same game object in Unity, it seems to be stuck on the default RTPC value.

Here's what I'm doing in the script:

Declared variables:

    public string rtpcID = VO_Volume;
    public float rtpcValue;
    int type = 0;

 

in the Update function:

AkSoundEngine.GetRTPCValue(rtpcID, gameObject, 0, out rtpcValue, ref type);

In the current Wwise documentation, GetRTPCValue calls for a RTPCValue_type, however that's not an available argument in the C# integration, and I saw in the QA board that someone just set it to be 0 but I'm not sure that's affecting anything.

 

If anyone has used this effectively I'd love to know what you did!

 

Thanks in advance,

Blake

Hi Blake,

the source of your problem seems to be the "type" parameter.

instead of directly providing a numerical value, may I suggest casting the enum AkQueryRTPCValue into an int instead, everything will be more clear if you do.

 

A value of 0 was equivalent to (int)AkQueryRTPCValue.RTPCValue_Default, which explains why your rtpc seemed stuck on the default value.

Rather, you should use (int)AkQueryRTPCValue.RTPCValue_GameObject

 

Enjoy

Hey thanks, Martin!

That pointed me in the right direction. It looks like I'm unable to cast it as an int and still reference it from that function, however I could just use a predefined int. So for those who might see this later what I'm doing now instead is exactly the same as what's in the original question, except type = 1 (which sets it to 'Global' instead of default, and 2 would set it to GameObject).

Thanks again, Martin!
