A brute force way to do this would be to add an IfCondition test to the [mState] measure to hide the entire skin if that value is not 1.Save the file and refresh the skin. The only time it will show anything is when your player is in "Play" mode.
Code:
[mState]Measure=PluginPlugin=WebNowPlayingPlayerName=SpotifyPlayerType=STATESubstitute="0":"playOff.png","1":"play.png","2":"pause.png"IfCondition=(mState=1)IfTrueAction=[!Show]IfFalseAction=[!Hide]Statistics: Posted by eclectic-tech — Today, 4:09 pm
