Sets the Source's directional volume cones. Together with Source:setDirection, the cone angles allow for the Source's volume to vary depending on its direction.
Source:setCone( innerAngle, outerAngle, outerVolume )
- The inner angle from the Source's direction, in radians. The Source will play at normal volume if the listener is inside the cone defined by this angle.
- The outer angle from the Source's direction, in radians. The Source will play at a volume between the normal and outer volumes, if the listener is in between the cones defined by the inner and outer angles.
number outerVolume (0)
- The Source's volume when the listener is outside both the inner and outer cone angles.
