Rotate is not working?

[GarrisonCool1]

I don't know if this is a bug or not (maybe I just suck at javascript), but why are these not rotating?
If its not a bug, could someone tell me why this isn't working?
My code:

particlesJS('particles-js', { "particles": { "number": { "value": 10, }, "color": { "value": "#000000" }, "shape": { "type": "star", }, // Why is this not working? "rotate": { "random": true, "direction": "clockwise", "speed": 20 }, "move": { "speed": 1, "direction": "bottom", "straight": true, } } });
