Hearing system #6
Description
Objects interacted with by the player will emit sounds, in order to make this make sense only player caused sounds sould be taken into account for the hearing system.
A system to propagate player noise emissions could be implemented.
For example, an object thrown by the player using the gravity gun will emit a noise on impact, however, if it hits another physics object, it will also mark that object so it will be allowed to emit a noise for a few moments.
Physics objects have a noise range, this noise range is the maximum possible range NPCs can detect noises emitted by the object.
Noise events may have a priority system, so the NPCs can react to them while investigating something else if it's a more important thing.
