I am using A-frame 1.5 for which the primitive “a-video” (https://aframe.io/docs/1.5.0/primitives/a-video.html) doesn’t provide spatial sound, the audio of videos si then playing the volume depen..ding of my rig position on the virtual world.

I want to show a chemical reaction with A frame. If user shows marker of Hydrozen and Oxygen then it will show Water molicule . Water molicule will show up in repalce of Oxgen marker. And It would better if hydrozen marker if close to near of oxygen then the chemical reaction will happen other wise not .Bellow the code i tried with.
