In this recipe, we will emulate a sense of hearing by developing two entities: a sound emitter and a sound receiver. It is based on the principles proposed by Millington for simulating a hearing system, and it uses the power of Unity colliders to detect receivers near an emitter.
The hearing function using a collider-based system
Getting ready
As with the other recipes based on colliders, we will need collider components attached to every object that is to be checked, and rigid body components attached to either emitters or receivers.
