    Problem with a simple expression

    Posted by Philippe Lessard on March 24, 2016 at 4:24 pm

    Hi,

    I cant figure out what wrong with this expression:

    opacity=thisComp.layer(“soundhomme”).effect(“Sound Keys”)(“Output 1”);
    if (opacity <; 50){ (100); }else{ (0) ; } Like you see I use the soundkey plugin output that return values between 0-100 from audio analyse. I want the value to be 0 or 100, so rounded values.I pickwip the output value of soundkey from the opacity of the layer I want to animate, than add the "opacity=" at the beginning of the expression, and the " if (opacity < 50){(100);}else{ (0) ; } " at the end. Also it return no error! Thanks opacity=thisComp.layer("soundhomme").effect("Sound Keys")("Output 1");
    if (opacity &lt; 50){
    (100);
    }else{ (0) ; }

    You shouldn’t use opacity as a variable name. I’d do it like this:

    sk=thisComp.layer(“soundhomme”).effect(“Sound Keys”)(“Output 1”);
    if (sk < 50) 100 else 0
