Changeset 5982 for code/branches/sound3/src/orxonox/sound

Timestamp:

Message:

Ambient Sounds are now locationally triggerable, i.e if the player comes close to an object, it's own ambient sound starts playing, while the sound of the outer object is paused. Upon leaving proximity of that object, the old sound is resumed. —> Triggerable by changing active state.
