Play SoundType where the creature's position is.

<p>Exactly, the position is between Position and Middle &mdash; SoundHeight = 0 means Position, SoundHeight = 1 means Middle, SoundHeight between means ... well, between Position and Middle. This can also be higher than 1 or lower than 0, should be treated like lerp between Position and Middle.

<p>If TiedToCreature then the sounds position will be updated as the creature will move, and when the creature object will be destroyed, sound will stop. If not TiedToCreature, then the sound will simply be done at creature's position, but then it will continue to be played independent of this creature.</p>

Can the approximate sphere be used for some collision-detection tasks.

<p>Set to <code>False</code> in descendants if Resource.Radius is not appropriate for this creature state.

<p>In this class, this is implemented to return <code>not Dead</code>. This is usually sensible, since only alive creatures need bounding sphere advantages (stairs climbing), and using sphere with dead creatures would unnecessarily force the sphere radius to be small and Middle to be high.</p>

You can set this to <code>False</code> to force the creature to die without making any sound. This is really seldom needed, usefull only to avoid a loud shriek noise when you kill many creatures at once. Primarily for use by debug menu &quot;kill all creatures&quot; and similar things.</p>
