i'm almost 100% sure it's not possible to return a nil on basic data
types, but just incase i'll post the question.
------------------------------------------------------
- (float)panForSoundWithName:(NSString *)soundName
{
OpenALSound *sound = [soundDictionary objectForKey:soundName];
if (!sound) return 0.0f;
return sound.pan;
}
------------------------------------------------------
so above i'd like to write "if (!sound) return nil;". my reasoning is
because some attributes to a sound object (like pan) are created only
when the sound is initialized. if there is no sound object than there
should also be no pan value to return. unfortunately, the float
default 0.0f is also the default value for pan (range from -1.0 to
1.0).
