Hi
I needed my video hotspots to have directional sound under VR so i used this
Code
<!-- put those lines under hotspot -->
<events name="hotspot_name_3dsound" keep="false" onviewchange="viewaction(hotspot_name)"/>
<action name="viewaction">
getlooktodistance(hotspot_dist, hotspot[%1].ath, hotspot[%1].atv);
set(new_volume, 0.8); <!-- 0.8 - maximum volume -->
div(hotspot_dist, 130); <!-- 130 - range -->
sub(new_volume, hotspot_dist);
if(new_volume GT 0.1, set(hotspot[%1].volume, get(new_volume))); <!-- 0.1 - minimum volume-->
<!--if sound can be muted use: set(hotspot[%1].volume, get(new_volume));-->
</action>
I don't know if this is most efficient way to do this, but i haven't found any other way to have directional sound for videos so that could be useful :)
(probably works for sound on volume too ;)
my example with that code:
