详细描述

The particles will continue roughly in the original direction, however will randomly drift to each side.

The code below produces an effect similar to falling snow.

Rectangle {
    width: 240
    height: 320
    color: "black"
    Particles {
        y: 0
        width: parent.width
        height: 30
        source: "star.png"
        lifeSpan: 5000
        count: 50
        angle: 70
        angleDeviation: 36
        velocity: 30
        velocityDeviation: 10
        ParticleMotionWander {
            xvariance: 30
            pace: 100
        }
    }
}
