Bug reports: Collision Radius set to 1 pixel when using a custom display object

    I added the below code to Particle2DUtils.createParticle2DFromDisplayObject to sync up the collision radius of my particles with the display object they are based upon. Otherwise the collision radius is set to 1 by default and does not behave properly. This does assume that width and height is the same, so perhaps there would be a better fix that would average the height and width to get a more accurate collisionRadius.

    // make new particles have the same radius as the width of the display object
    particle.collisionRadius = obj.width/2;
    //

    right above:
    particle.image = obj;
    return particle;

    Good idea. I've added it (using the average of width and height) in createParticle2DFromDisplayObject and createRectangleParticlesFromBitmapData.

    Thanks
