\qmltype Friction \instantiates QQuickFrictionAffector \inqmlmodule QtQuick.Particles\inherits Affector

For applying friction proportional to the particle's current velocity.

\qmlproperty real QtQuick.Particles::Friction::factor

A drag will be applied to moving objects which is this factor of their current velocity.

\qmlproperty real QtQuick.Particles::Friction::threshold

The drag will only be applied to objects with a velocity above the threshold velocity. The drag applied will bring objects down to the threshold velocity, but no further.

The default threshold is 0
