Then, you just have to "subscribe" your control busses to this state group to obtain different mix values per subscribed Wwise object, per state.
Other advantages to this includes:
- You also have control over the interpolation time between each state in the State Group Property Editor.
- You get access not only to volume but also to LFE volume, low pass filter and pitch
- Property changes can be done in "Absolute" or "Relative" values.
- State changes can be triggered by the code or by an Event using the SetState actions.
- You are not limited to control busses. You can also subscribe Actor-mixer objects, containers, sounds and even interactive music objects to the state. This gives you total control over your mix and it can certainly help to reduce the number of required control busses in your project.
