Okay, I saw that code in the BG widget and I am using it in my app.
However, I do not know how to trigger it.The problem is, that I have to read what is playing, when I start the app.
Otherwise I cannot show title information and I do not know what the musicstate is.global.GB = function(j) {
if (debug ==1) print("global.GB");
switch (j.t) {
case "musicinfo":
musicInfo = j;
draw();
break;
case "musicstate":
musicState = j.state;
draw();
break;
}
};
You just need to define a function called
GB
