You need some scripts, No No NO don't run, take it easy.
Create a new script, attach it to an empty gameobject
Imagine this gameobject is your keys input manager.
Script:
using UnityEngine; // mandatory
using System.Collections; // mandatory... i think
public class test : MonoBehaviour { // NAME OF THE CLASS MUST BE THE SAME AS THE FILENAME; Here; test.cs
void Update () { // Called each frame
float rtpcValueToSend = 22; // set the rtpc as you which, value is declared as a float, no need to write 22f
if (Input.GetKey ("up")) { // will execute the next commands in {} if the up key is pressed
AkSoundEngine.SetRTPCValue ("nameofyourrtpc", rtpcValueToSend); // send rtpc to wwise
}
}
}
You should look at AkSoundEngine class, most functions are called with this class,
for example, AksoundEngine.PostEvent("play_Footstep, gameObject)
