I thought there was too little colors in the snowstorm.js, so I've tampered a bit with it.

Here's the result.
If anyone figures out how to center the rotation successfully in this js I'd like to see it. I did a different effect instead which works pretty well.
Hoping somebody will have fun with this one.

Me too, I got the rotation to work by rotating around the center, like this:

Code: Select all

    ctx.translate(ScreenWidth / 2, ScreenHeight / 2);
    ctx.rotate(degrees * Math.PI / 180);
    ctx.translate(-ScreenWidth / 2, -ScreenHeight / 2);

Frame by frame it rotates a tiny bit, smoothing when zoomin up, creating a pretty neat effect!

The variable degrees are oscillating between -10 to +10 adding to the effect.
