I've been trying to use audio analyser to make a background like Super Hexagon. I'm using Construct 2 r180. To preview, I am using Chrome Canary.
The event is
System > General > Compare 2 Values > First value: round(Audio.AnalyserRMSLevel("pew", 0)) | Comparison: > Greater than | Second value: -22
The action is
System > Layers & Layout > Set layer background color > Layer: 0 | Color: rgb(random(255), random(255), random(255))
I found that Audio.AnalyserRMSLevel("pew", 0) always outputs 0, regardless if the music is off or on.
Then I used the Audio analyser sample project and imported the same music and changed the play audio action to play my music, and then I imported the code from above, and it worked exactly how I wanted it to.
