RTPC Tied to Boy's speed?

Question

I've tried using the RTPC Velocity on volume and pitch of different sounds, but they are not altered in game when the boy is moving at different speeds.

 

Am I misunderstanding what this RTPC actually does?

Hi James, 

The RTPC_VELOCITY game parameter should work. Couple of things to check:

1. RTPC_VELOCITY game parameter values are updated on the 'Boy' game object. If the sounds that you've attached RTPC curves are not triggered from the 'Boy' game object, nothing will happen (you'll get the default game parameter value). 
2. Similarly, if you've attached the RTPC on a global audio object like a bus, it will also not be updated.
3. It could also be related with the SoundBank generation. I suggest you look at this answer: https://www.audiokinetic.com/qa/189/limbo-sound-bank-not-updating

Hope this helps,

Ah, so it's tied to everything within the Boy event. Thanks!
