Hi, I'm a sound designer and cowboy programmer. By cowboy I mean show me how to do something and I can apply it to my own objects / set my own variables etc etc. This is beyond my experience but something tells me it should be possible.

I have been using some scripts created by another similar sound designer/programmer but obviously slightly better than myself!

He has created this script to tell FMOD where the player is relative to a sound emitter by passing it the 3D info about the player. Problem is, it was written for a 1st person game. I am making a platformer. Basically I need this to correspond to the Camera instead as, in a platformer, the camera is the audio listener. The stuff about footsteps etc I will need to keep on the actual player but I'm not so worried about that right now so edit that out (same with the wallpat etc). Could someone edit this script for me to be attached to the camera instead of the player so that FMOD can receive its 3D position info.

Here is some basic FMOD 3D Listener programmers (C++ not C# but should be similar) info:

EventSystem::set3DListenerAttributes This updates the position, velocity and orientation of the specified 3D sound listener.

C++ Syntax

FMOD_RESULT EventSystem::set3DListenerAttributes( int listener, const FMOD_VECTOR * pos, const FMOD_VECTOR * vel, const FMOD_VECTOR * forward, const FMOD_VECTOR * up );

C Syntax

FMOD_RESULT FMOD_EventSystem_Set3DListenerAttributes( FMOD_EVENTSYSTEM * eventsystem, int listener, const FMOD_VECTOR * pos, const FMOD_VECTOR * vel, const FMOD_VECTOR * forward, const FMOD_VECTOR * up );

Parameters

listener

Listener ID in a multi-listener environment. Specify 0 if there is only 1 listener.

pos

Address of a variable that receives the position of the listener in world space, measured in distance units. You can specify 0 or NULL to not update the position.

vel

Address of a variable that receives the velocity of the listener measured in distance units per second. You can specify 0 or NULL to not update the velocity of the listener.

forward

Address of a variable that receives the forwards orientation of the listener. This vector must be of unit length and perpendicular to the up vector. You can specify 0 or NULL to not update the forwards orientation of the listener.

up

Address of a variable that receives the upwards orientation of the listener. This vector must be of unit length and perpendicular to the forwards vector. You can specify 0 or NULL to not update the upwards orientation of the listener.

and the script in question (FMODPlayer.cs):
