|
* This component contains an Entity reference which should link to an Entity
|
|
* that has a TriggerAreaComponent or PhysX Collider with Trigger enabled. That Trigger Area (and shape) will act as the
|
|
* broad-phase trigger. Once Entities go inside, this component will track their
|
|
* movement until they leave the Trigger Area.
|
|
* The AudioAreaEnvironmentComponent's Entity requires it's own Shape that defines
|
|
* where the Environment is fully applied. This shape should be placed interior
|
|
* to the Trigger Area. Entities that are between the two shapes will 'fade'
|
|
* the environment amount based on the Environment fade distance property.
