Hehe, sorry bout that ...found out what I have to do know though....painfully simple after all the brain-ache.
All I have to do is use two 3D vectors to describe the listener rather than just one. Then when i have an incoming sound I can angle check against both of these two vectors and then determining which side of the listener's "face" the sound is hitting is easy !
Yay !...well I'm not sure if I'll have time to implement it today...busy times...but this week it will be finished and implemented....It will mean some big aditions to the level editor but that's fine !
Oh and Jerry, the technical stuff was just for you
